Abstract
Being intensified by the recent financial crisis in 2008, debt crises seemto be looming ahead among many OECD countries due to the runawayaccumulation of government debts. This paper first explores them as asystemic failure of the current debt money system. Secondly, with anintroduction of open macroeconomies, it examines how the current sys-tem can cope with the liquidation of government debt, and obtains thatthe liquidation of debts triggers recessions, unemployment and foreigneconomic recessions contagiously. Thirdly, it explores the workings of apublic money system proposed by the American Monetary Act and findsthat the liquidation under this alternative system can be put into effectwithout causing recessions, unemployment and inflation as well as for-eign recessions. Finally, public money policies that incorporate balancingfeedback loops such as anti-recession and anti-inflation are introduced forcurbing GDP gap and inflation. They are posed to be simpler and moreeffective than the complicated Keynesian policies.
1 Introduction: Public vs Debt Money
I have explored in the paper [16]1 how accumulating government debts couldbe liquidated under two different macroeconomic systems; that is, a current
∗The original paper was presented at the 29th International Conference of the SystemDynamics Society, Washington D.C., USA, July 25, 2011. On the following day, July 26, itwas presented at the US Congressional Briefing, Cannon 402, sponsored by the CongressmanDennis Kucinich. Then, it is moderately revised by adding comparative analyses of liquidationpolicies under a debt money system, and presented with the same title at the 7th Annual AMIMonetary Reform Conference in Chicago, USA, Sept. 30, 2011.
1With its modest revision, the paper was presented at the monetary reform conf. inChicago, organized by the American Monetary Institute, on Oct. 1, 2010, for which the
1
macroeconomic system of money as debt, and a debt-free macroeconomic systemadvocated by the American Monetary Act. What I have found is that theliquidation of government debt under the current macroeconomic system ofmoney as debt is very costly; that is, it triggers economic recessions, whilethe liquidation process under a debt-free money system can be accomplishedwithout causing recessions and inflations. The results are, however, obtained ina simplified closed macroeconomic system in which no labor market exists.
Accordingly, the purpose of this paper is to expand the previous simplemacroeconomic system to complete open macroeconomies in which labor mar-ket and foreign exchange market exist, and analyze if similar results could beobtained in the open macroeconomies for a system of money as debt and adebt-free money system. For the examination, I have felt a strong necessityto briefly redefine money and its system in this introductory section to avoidfurther confusions caused by different usage of terminologies. In the previouspaper, a system of money as debt was used to describe the current monetarysystem, and a debt-free money system was used as a system that is proposed bythe American Monetary Act. Let us redefine these terminologies in a uniformfashion as follows.
Public Money
From early days in history money has been in circulation as a legal tender asAristotle (384-322 BC) phrased that “Money exists not by nature but by law[17].” Hence, money has been by definition a fiat money as legal tender. Moneythus created, whether it could be tangible or intangible, has to have the followingthree features as explained by many economics textbooks.
• Medium of Exchange
• Unit of Account
• Store of Value
Money
Commodity
Receipts Payments
Sales Purchases
Figure 1: Public Money
Using system dynamics con-cept of stock and flow, thesefunctions of money may beuniformly illustrated in Figure1 in which flows of money suchas receipts and payments ac-complish counter-transactionsof sales and purchases of com-modity (means of exchange)according to a uniform scale(unit of account), and the
following award was given; “Advancement of Monetary Science and Reform Award to Prof.Kaoru Yamaguchi, Kyoto, Japan, For his advanced work in modeling the effects on nationaldebt of the American Monetary Act”.

Table 1: Public vs Debt Money
amount of money thus circulated is stored as a stock of money as a resultof these transactions (store of value). In system dynamics stocks of money andcommodity can be said to co-flow all the time in an opposite direction.
Money, having the above three features as a legal tender, could take a formof commodities such as shell, silk (cloth) and stone, of precious metals such ascopper, silver and gold, of paper such as Goldsmith and gold certificates andbank notes, and of intangible numbers and electronic digits such as depositsand credits. In short, any form that performs three features has been generallyaccepted as money that has a purchasing power.
Among these various forms of money, let us define public money here as theone that is a fiat money of legal tender and issued only by the government andsovereignty as public utility for transactions. Examples of public money aresummarized in Table 1.
Debt Money
Tangible money currently in use are coinage and bank notes. Coins are mintedby the government as subsidiary currency. Hence, it is public money by def-inition. On the other hand, bank notes are issued by central banks that areindependent of the government and privately owned in many countries. For in-stance, Federal Reserve System, the central bank in the United States, is 100%privately owned [2] and Bank of Japan is 45% privately owned. Hence, govern-ments are obliged to borrow from central banks and in this sense bank notesare regarded as a part of debt money.
Theoretically, the issuance of money by the private organizations can be pos-sible only when government or sovereignty legally allow them to create money,since “money exists by law” as pointed out above. Historically this occurredwhen Bank of England was founded in 1694 and endowed with the right to is-sue money as its bank notes. In the United States, this was instituted by theFederal Reserve Act in 1913.
In addition to the tangible money such as bank notes and coinage, bank
3
deposits or credits created as loans by commercial banks also play a role ofmoney, though intangible, because they can be withdrawn any time, at request,for transactions. This process of credit creation is made possible by the so-calleda fractional reserve banking system. For detailed analysis see [10].
In sum, under the current financial system, currency in circulation such asbank notes and coinage and bank deposits play a role of money. The amountof money that is available at a certain point of time is called money supply orstock, which is thus defined as
Money Supply = Currency in Circulation + Deposits (1)
Commodity
SalesPurchases
Money(Currency inCirculation)
Deposits
Loan
Money Supply
Receipts (MS) Payments (MS)
Figure 2: Debt Money
In system dynamics ter-minology, it is nothing buta money stock as illus-trated in Figure 2. To dis-tinguish this type of moneyfrom public money, let uscall it debt money, be-cause money of this typeis only created when gov-ernment and commercialbanks come to borrowfrom central banks (high-powered money), and pro-ducers and consumers cometo borrow from commercial banks (bank deposits and credits are called low-powered money). In my previous paper [16], this system is called system ofmoney as debt. Almost all of macroeconomic textbooks in use such as [4], [5],[6], [3] justify the current macroeconomic system of debt money without men-tioning an alternative system, if any, such as the money system proposed by theAmerican Monetary Act to be explained below.
The American Monetary Act
After the Great Depression in 1929, two banking reforms were proposed to avoidfurther serious recessions; that is, the Banking Act of 1933 known as the Glass-Steagall Act and the Chicago Plan. The Glass-Steagall Act was intended to sep-arate banking activities between Wall Street investment banks and depositorybanks. The act was unfortunately repealed in 1999 by the Gramm-Leach-BlileyAct. This repeal was criticized as having triggered the recent financial crisis ofsubprime mortgage loans, following the collapse of Lehman Brothers in 2008.On-going movement of financial reforms in the US is an attempt to bring backstricter banking regulations in the spirit of the Glass-Steagal Act.
The other reform was simultaneously proclaimed by the great economists in1930s such as Henry Simons and Paul Douglas of Chicago, Irving Fisher of Yale,Frank Graham and Charles Whittlesley of Princeton, Earl Hamilton of Duke,
4
and Willford King, etc. [18], who had seen a debt money system as a rootcause of the Great Depression. Their solution for avoiding a possible “GreatDepression” in the future is called the Chicago Plan. For instance, Irving Fisher,a great monetary economist in those days, was active in establishing a monetaryreform to stabilize the economy out of recessions such as the Great Depression.His own plan is known as “100% Money Plan”
I have come to believe that the plan, ”properly worked out andapplied, is incomparably the best proposal ever offered for speedilyand permanently solving the problem of depressions; for it wouldremove the chief cause of both booms and depressions, namely theinstability of demand deposits, tied as they are now, to bank loans.”[1, p. 8]
In contrast with the Glass-Steagal Act, the Chicago Plan has failed to be im-plemented.
The American Monetary Act2 endeavors to restore the proposal of theChicago Plan or 100% Money Plan by replacing the Federal Reserve Act of1913. In our terminology above, it is nothing but the restoration of a publicmoney system from a debt money system. Specifically, the Act tries to incor-porate the following three features. For details see [16] and [17, 18].
• Governmental control over the issue of money
• Abolishment of credit creation with full reserve ratio of 100%
• Constant inflow of money to sustain economic growth and welfare
When full reserve system is implemented by the Act, bank reserves becomeequal to deposits so that we have
Money Supply = Currency in Circulation + Deposits= Currency in Circulation + Reserves= High-Powered Money (2)
Accordingly, under the public money system, money is created only by thegovernment, and money supply becomes public money only3.
As a system dynamics researcher, I have become interested in the systemdesign of macroeconomics proposed by the American Monetary Act, and posed a
2On Dec. 17, 2010, a bill based on the American Monetary Act was introduced to theUS House Committee on Financial Services by the congressman Dennis Kucinich. This bill iscalled H.R. 6550 National Emergency Employment Defense Act of 2010 (NEED). A similarproposal “Towards A Twenty-First Century Banking And Monetary System” was recentlysubmitted jointly by PositiveMoney, nef(the new economics foundation), and Prof. RichardWerner of the Univ. of Southampton, to the Independent Commission on Banking, UK.
3Money supply is also defined in terms of high-powered money as
Money Supply = m ∗ High-Powered Money (3)
where m is a money multiplier. Under a full reserve system, money multiplier becomes unitary,m = 1, so that money can no longer be created by commercial banks.

question whether this public money system of macroeconomy can solve the mostimminent problem our economy is facing; that it, accumulation of governmentdebt. My previous work [16] positively answered the question under a simplemodeling framework. Before exploring it under the complete model of openmacroeconomies here, let us probe how serious our current issue of accumulatingdebt is.
2 Debt Crises As A Systemic Failure
Debt Crises Looming Ahead
Being intensified by the recent financial crisis following the collapse of LehmanBrothers in 2008, severe crisis of sovereign or government debts seems to belooming ahead. Let us explore how serious accumulating national debts are.Table 2 shows that, among 33 OECD countries, 18 countries are suffering fromhigher debt-to-GDP ratios of more than 50% in 2010. Average ratio of these 33countries is 66.7%, while world average ratio of 131 countries is 58.3%4. Thisimplies that developed countries are facing debt crises more seriously than manydeveloping countries. .

Table 2: Public Debt-GDP Ratio(%) of OECD Countries in 2010
Let us now take a look at the US national debt. Following the Lehman shockin 2008, US government is forced to bail out troubled banks and corporationswith taxpayers’s money, and the Fed continued printing money to purchase poi-soned subprime and related securities. In fact, according to the Federal ReserveStatistical Release H.4.1 the Fed assets jumped more than doubles in a yearfrom $905 billion, Sept. 3, 2008, to $2,086 billion on Sept. 2, 2009. This un-usual yearly increase was mainly caused by the abnormal purchase of federal

agency debt securities ($119 billion) and mortgage-backed securities ($625 bil-lion). In addition, US government is obliged to spend more budget on war inMiddle East. These factors contributed to accumulate US national debt beyond14 trillion dollars as of Feb. 2011, more than 4 trillion dollars’ increase sinceLehman shock in Sept. 2008. Figure 3 (line 2) illustrates how fast US nationaldebt has been accumulating almost exponentially5. From a simple calibration

Figure 3: U.S. National Debt and its Forecast: 1970 - 2020
of data between 1970 through 2011 , the best fit of their exponential growthrate is calculated to be 9% !, which in turn implies that a doubling time ofaccumulating debt is 7.7 years. If the current US national debt continues togrow at this rate, this means that the doubling year of the 14 trillion dollars’debt in 2011 will be 2019. In fact, our debt forecast of that year becomes 29trillion dollars. Moreover, in 2020, the US national debt will become higherthan 31 trillion dollars, while US GDP in 2020 is estimated to be 24 trilliondollars according to the Budget of the U.S. Government, Fiscal Year 2011; thatis, the debt-to-GDP ratio in the US will be 129%!.
Can such an exponentially increasing debt be sustained. From system dy-namics point of view, it is absolutely impossible. In fact, following the financialcrisis of 2008, sovereign debt crisis hit Greece in 2009, then Ireland, and nowPortugal is said to be facing her debt crisis. Debt crises are indeed loomingahead among OECD countries.
A Systemic Failure of Debt Money
From the quantity theory of money MV = PT , where M is money supply, Vis its velocity, P is a price level and T is the amount of annual transactions, it

can be easily foreseen that transactions of a constantly growing economy PTdemand for more money M being incessantly put into circulation. Under thecurrent debt money system this increasing demand for money has been met bythe following monetary standards.
Gold Standard Failed (1930s) Historically speaking gold standard originatedfrom the transactions of goldsmith certificates, which eventually developedinto convertible bank notes with gold. Due to the limitation of the sup-ply of gold, this gold standard system of providing money supply wasabandoned in 1930s, following the Great Depression.
Gold-Dollar Standard Failed (1971) Gold standard system was replacedwith the Bretton Woods system of monetary management in 1944. Underthe system, convertibility with gold is maintained indirectly through USdollar as a key currency, and accordingly called the gold-dollar standard.Due to the increasing demand for gold from European countries, US pres-ident Richard Nixon was forced to suspend gold-dollar convertibility in1971, and the so-called Nixon Shock hit the world economy.
Dollar Standard Collapsing (2010s?) Following the Nixon shock, flexibleforeign exchange rates were introduced, and US dollar began to be usedas a world-wide key currency without being supported by gold. As aresult, central banks acquired a free hand of printing money without beingconstrained by the amount of gold. Due to the exponentially accumulatingdebt of the US government as observed above, US dollar is now under apressure of devaluation, and the dollar standard system of the last 40 yearsis destined to collapse sooner or later.
As briefly assessed above, we are now facing the third major systemic failuresof debt money, following the failures of gold standard and gold-dollar standardsystems. Specifically, our current debt money system seems to be heading to-ward three impasses: defaults, financial meltdown and hyper-inflation. By usingcausal loop diagram of Figure 4, let us now explore a conceivable systemic failureof the current debt money system.
Defaults
A core loop of the systemic failure is the debt crisis loop. This is a typicalreinforcing loop in which debts increase exponentially, which in turn increasesinterest payment, which contributes to accumulate government deficit into debt.In fact, interest payment is approximately as high as one third of tax revenuesin the US and one fourth in Japan. Eventually, governments may get con-fronted with more difficulties to continue borrowing for debt reimbursements,and eventually be forced to declare defaults.

Financial Meltdown6
Exponential growth of debt eventually leads to the second loop of financial crisis.To be specific, a runaway accumulation of government debt may cause nominalinterest rate to increase eventually, because government would be forced to keepborrowing by paying higher interests7. Higher interest rates in turn will surelytrigger a drop of government security prices, deteriorating values of financialassets among banks, producers and consumers. Devaluation of financial assetsthus set off may force some banks and producers to go bankrupt in due course.
Under such circumstances, government would be forced to bail out or intro-duce another stimulus packages, increasing deficit as flow and piling up debt asstock. This financial crisis loop will sooner or later lead our economy toward
6This section name was originally “Meltdown” in the paper submitted in the morning ofMarch 11, 2011, when eastern part of Japan was hit by historical earthquake and tsunamiin the afternoon of the day, followed by the meltdown of the Fukushima Dai-ichi nuclearpower plants in a day or so. To distinguish it from the nuclear meltdown, it is revised as“Financial Meltdown”. We are indeed at a turning point of history revolved by these twomajor meltdowns.
7This feedback loop from the accumulating debt to the higher interest rate is not yet fullyincorporated in our model below.

a second impasse which is in this paper called financial meltdown, following[8]. Recent financial crisis following the burst of housing bubbles, however, isnothing but a side attack in this financial crisis loop, though reinforcing thedebts crisis. Tougher financial regulations being considered in the aftermathof financial crisis might reduce this side attack. Yet they do not vanquish thefinancial crisis loop originating from the debts crisis loop in Figure 4.
Hyper-Inflation
To avoid higher interest rate caused by two reinforcing crisis loops, centralbanks would be forced to increase money supply (balancing loop), which in-evitably leads to a third impasse of hyper-inflation. Incidentally, this possibilityof hyper-inflation in the US may be augmented by the aftermath behaviors ofthe Fed following the Lehman Shock of 2008. In fact, as seen above mone-tary base or high-powered money doubled from $905 billion, Sept. 3, 2008, to$1,801 billion, Sept. 2, 2009, within a year (FRB: H.3 Release). Thanks to thedrastic credit crunch, however, this doubling increase in monetary base didn’ttrigger inflation so far. In other words, M1 consisting of currency in circulation,traveler’s checks, demand deposits, and other checkable deposits, only increasedfrom $1,461 billion in Sept. 2008 to $1,665 billion in Sept. 2009 (FRB: H.6Release), which implies that money multiplier dropped from 1.61 to 0.92. As ofFeb. 2011, it is 0.91. In short, traditional monetary expansion policy by the Feddidn’t work to restore the US economy so far. Yet, these tremendous increasein monetary base will, as a monetary bomb, force the US dollars to be devaluedsooner or later. Once it gets burst, hyper-inflation will attack world economyin the foreseeable future. One of the main subject of G20 meetings last year inSeoul, Korea was how to avoid currency wars being led by the devaluation ofdollar.
As discussed above in this way, current economies built on a debt moneysystem seems to be getting trapped into one of three impasses, and governmentmay be eventually destined to collapse due to a heavy burden of debts. Theseare hotly debated scenarios about the consequences of the rapidly accumulatingdebt in Japan, whose debt-GDP ratio in 2009 was 196.4% as observed above; thehighest among OECD countries! Greece has almost experienced this impasse in2009.
After all, current macroeconomic system has been structurally fabricated bythe Keynesian macroeconomic policy framework in which it is proposed thatthe additional government expenditure can rescue the troubled economy fromrecession. Yet, it fails to analyze why this fiscal policy is destined to accumulategovernment debt as mentioned above. In fact, even though GDP gap is very hugein Japan, yet due to the fear of runaway accumulation of debt, the Japanesegovernment is very reluctant to stimulate the economy and, in this sense, itseems to have totally lost its discretion of public policies for the welfare ofpeople even though production capacities and workers have been sitting idleand ready to be called in service. In other words, Keynesian fiscal policy cannot
10
be applied to the troubled Keynesian macroeconomy. With zero interest rate,its monetary policy has already lost its discretion as well. Isn’t this an irony ofthe Keynesian theory? Current debt money system of macroeconomy seems tohave fallen into the dead-end trap.
With these preparatory analysis of the current economic situations in mind,we are now in a position to expand our previous model to a complete modelof open macroeconomics, and examine how government debt can be liquidatedunder two different money systems; that is, debt money system and publicmoney system.
3 Modeling A Debt Money System
Since 2004 I have been working step-by-step on constructing macroeconomicmodels in [10], [11], [12] and [13] based on the method of accounting system dy-namics developed in [9]. This series of macroeconomic modeling was completedin [14] with a follow-up analytical refinement method of price adjustment mech-anism in [15]. The model of open macroeconomies in this paper is mostly basedon the model in [14].
For the convenience of the reader, main transactions of the open macroe-conomies by producers, consumers, government, banks and the central bank arereplicated here.
Producers
Main transactions of producers, which are illustrated in Figure 33 in the ap-pendix, are summarized as follows.
• Out of the GDP revenues producers pay excise tax, deduct the amount ofdepreciation, and pay wages to workers (consumers) and interests to thebanks. The remaining revenues become profits before tax.
• They pay corporate tax to the government out of the profits before tax.
• The remaining profits after tax are paid to the owners (that is, consumers)as dividends, including dividends abroad. However, a small portion ofprofits is allowed to be held as retained earnings.
• Producers are thus constantly in a state of cash flow deficits. To makenew investment, therefore, they have to borrow money from banks andpay interest to the banks.
• Producers imports goods and services according to their economic activi-ties, the amount of which is assumed to be a portion of GDP in our model,though actual imports are also assumed to be affected by their demandcurves.
11
• Similarly, their exports are determined by the economic activities of aforeign economy, the amount of which is also assumed to be a portion offoreign GDP.
• Produces are also allowed to make direct investment abroad as a portionof their investment. Investment income from these investment abroad arepaid by foreign producers as dividends directly to consumers as ownersof assets abroad. Meanwhile, producers are required to pay foreign in-vestment income (returns) as dividends to foreign investors (consumers)according to their foreign financial liabilities.
• Foreign producers are assumed to behave in a similar fashion as a mirrorimage of domestic producers
Consumers
Main transactions of consumers, which are illustrated in Figure 34 in the ap-pendix, are summarized as follows.
• Sources of consumers’ income are their labor supply, financial assets theyhold such as bank deposits, shares (including direct assets abroad), anddeposits abroad. Hence, consumers receive wages and dividends fromproducers, interest from banks and government, and direct and financialinvestment income from abroad.
• Financial assets of consumers consist of bank deposits and governmentsecurities, against which they receive financial income of interests frombanks and government.
• In addition to the income such as wages, interests, and dividends, con-sumers receive cash whenever previous securities are partly redeemed an-nually by the government.
• Out of these cash income as a whole, consumers pay income taxes, andthe remaining income becomes their disposal income.
• Out of their disposable income, they spend on consumption. The remain-ing amount is either spent to purchase government securities or saved.
• Consumers are now allowed to make financial investment abroad out oftheir financial assets consisting of stocks, bonds and cash. For simplicity,however, their financial investment are assumed to be a portion out oftheir deposits . Hence, returns from financial investment are uniformlyevaluated in terms of deposit returns.
• Consumers now receive direct and financial investment income. Similarinvestment income are paid to foreign investors by producers and banks.The difference between receipt and payment of those investment income
12
is called income balance. When this amount is added to the GDP rev-enues, GNP (Gross National Product) is calculated. If capital depreciationis further deducted, the remaining amount is called NNP (Net NationalProduct).
• NNP thus obtained is completely paid out to consumers, consisting ofworkers and shareholders, as wages to workers and dividends to share-holders, including foreign shareholders.
• Foreign consumers are assumed to behave in a similar fashion as a mirrorimage of domestic consumers.
Government
Transactions of the government are illustrated in Figure 35 in the appendix,some of which are summarized as follows.
• Government receives, as tax revenues, income taxes from consumers andcorporate taxes from producers.
• Government spending consists of government expenditures and paymentsto the consumers for its partial debt redemption and interests against itssecurities.
• Government expenditures are assumed to be endogenously determinedby either the growth-dependent expenditures or tax revenue-dependentexpenditures.
• If spending exceeds tax revenues, government has to borrow cash fromconsumers and banks by newly issuing government securities.
• Foreign government is assumed to behave in a similar fashion as a mirrorimage of domestic government.
Banks
Main transactions of banks, which are illustrated in Figure 36 in the appendix,are summarized as follows.
• Banks receive deposits from consumers and consumers abroad as foreigninvestors, against which they pay interests.
• They are obliged to deposit a portion of the deposits as the requiredreserves with the central bank.
• Out of the remaining deposits, loans are made to producers and banksreceive interests to which a prime rate is applied.
• If loanable fund is not enough, banks can borrow from the central bankto which discount rate is applied.
13
• Their retained earnings thus become interest receipts from producers lessinterest payment to consumers and to the central bank. Positive earningswill be distributed among bank workers as consumers.
• Banks buy and sell foreign exchange at the request of producers, con-sumers and the central bank.
• Their foreign exchange are held as bank reserves and evaluated in termsof book value. In other words, foreign exchange reserves are not depositedwith foreign banks. Thus net gains realized by the changes in foreignexchange rate become part of their retained earnings (or losses).
• Foreign currency (dollars in our model) is assumed to play a role of keycurrency or vehicle currency. Accordingly foreign banks need not set upforeign exchange account. This is a point where a mirror image of openmacroeconomic symmetry breaks down.
Central Bank
Main transactions of the central bank, which are illustrated in Figure 37 in theappendix, are summarized as follows.
• The central bank issues currencies against the gold deposited by the public.
• It can also issue currency by accepting government securities through openmarket operation, specifically by purchasing government securities fromthe public (consumers) and banks. Moreover, it can issue currency bymaking credit loans to commercial banks. (These activities are sometimescalled money out of nothing.)
• It can similarly withdraw currencies by selling government securities to thepublic (consumers) and banks, and through debt redemption by banks.
• Banks are required by law to reserve a certain amount of deposits withthe central bank. By controlling this required reserve ratio, the centralbank can control the monetary base directly.
• The central bank can additionally control the amount of money supplythrough monetary policies such as open market operations and discountrate.
• Another powerful but hidden control method is through its direct influenceover the amount of credit loans to banks (known as window guidance inJapan.)
• The central bank is allowed to intervene foreign exchange market; that is,it can buy and sell foreign exchange to keep a foreign exchange ratio stable(though this intervention is actually exerted by the Ministry of Finance inJapan, it is regarded as a part of policy by the central bank in our model).
14
• Foreign exchange reserves held by the central bank is usually reinvestedwith foreign deposits and foreign government securities, which are, how-ever, not assumed here as inessential.
4 Behaviors of A Debt Money System
Mostly Equilibria in the Real Sector
Our open macroeconomic model is now completely presented. It is a genericmodel, out of which diverse macroeconomic behaviors are generated, dependingon the purpose of simulations. In this paper let us focus on an equilibriumgrowth path as a benchmark for our analysis to follow. An equilibrium state iscalled a full capacity aggregate demand equilibrium if the following three outputand demand levels are met:
Full Capacity GDP = Desired Output = Aggregate Demand (4)
If the economy is not in the equilibrium state, then actual GDP is determinedby
GDP = MIN (Full Capacity GDP, Desired Output ) (5)
In other words, if desired output is greater than full capacity GDP, then actualGDP is constrained by the production capacity, meanwhile in the opposite case,GDP is determined by the amount of desired output which producers wish toproduce, leaving the capacity idle, and workers being laid off.
Even though full capacity GDP is attained, full employment may not berealized unless the following equation is not met;
Potential GDP = Full Capacity GDP. (6)
Does the equilibrium state, then, exist in the sense of full capacity GDP and fullemployment? To answer these questions, let us define GDP gap as a differencebetween potential GDP and actual GDP, and its ratio to the potential GDP as
GDP Gap Ratio =Potential GDP - GDP
Potential GDP(7)
By trial and error, mostly equilibrium states are attained when price elastic-ity e is 3, together with all other adjusted parameters, as illustrated in Figure5.
Our open macrodynamic model has more than 900 variables that are in-terrelated one another, among which, as benchmark variables for comparativeanalyses in this paper, we mainly focus on two variables: GDP gap ratio andunemployment rate. Figure 6 illustrates these two figures at the mostly equi-librium states. GDP gap ratios are maintained below 1% after the year 6, andunemployment ratios are less than 0.65% at their highest around the year 6, ap-proaching to zero; that is, full employment. The reader may wonder why theseare a state of mostly equilibria, because some fluctuations are being observed.

Economic activities are alive like human bodies, whose heart pulse rates, evenof healthy persons, fluctuate between 60 and 70 per minute in average. Yet,they are a normal state. In a similar fashion, it is reasonable to consider thesefluctuations as normal equilibrium states.

Money out of Nothing
For the attainment of mostly equilibria, enough amount of money has to beput into circulation to avoid recessions caused by credit crunch as analyzed in[12]. Demand for money mainly comes from banks and producers. Banks areassumed to make loans to producers as much as desired so long as their vaultcash is available. Thus, they are persistently in a state of shortage of cash aswell as producers. In the case of producers, they could borrow enough fund frombanks. From whom, then, should the banks borrow in case of cash shortage?
16
In a closed economic system, money has to be issued or created within thesystem. Under the current financial system of debt money, only the central bankis endowed with a power to issue money within the system, and make loansto the commercial banks directly and to the government indirectly throughthe open market operations. Commercial banks then create credits under afractional reserve banking system by making loans to producers and consumers.These credits constitute a great portion of money supply. In this way, moneyand credits are only crated when commercial banks and government as well asproducers and consumers come to borrow at interest. Under such circumstances,if all debts are repaid, money ceases to exist. This is an essence of a debt moneysystem. The process of creating money is known as money out of nothing.
Figure 7 indicates unconditional amount of annual discount loans and itsgrowth rate by the central bank at the request of desired borrowing by banks.In other words, money has to be incessantly created and put into circulation inorder to sustain an economic growth under mostly equilibrium states. Roughlyspeaking, a growth rate of credit creation by the central bank has to be inaverage equal to or slightly greater than the economic growth rate as suggestedby the right hand diagram of Figure 7, in which line 1 is a growth rate of credit

Accumulation of Government Debt
So long as the mostly equilibria are realized in the economy, through monetaryand fiscal policies in the days of recession, no macroeconomic problem seemsto exist. This is a positive side of the Keynesian macroeconomic theory. Yetbehind the full capacity aggregate demand growth path in Figure 5 govern-ment debt continues to accumulate as the line 1 in the left diagram of Figure 8illustrates. This is a negative side of the Keynesian theory. Yet most macroe-conomic textbooks neglect or less emphasize this negative side, partly becausetheir macroeconomic frameworks cannot handle this negative side of the debtmoney system.
In the model here primary balance ratio is initially set to be one and balanced
17
budget is assumed to the effect that government expenditure is set to be equalto tax revenues, and no deficit arises. Why, then, does the government continueto accumulate debt? Government deficit is precisely defined as

Figure 8: Accumulation of Government Debt and Debt-GDP Ratio
Deficit = Tax Revenues - Expenditure - Debt Redemption - Interest (8)
Therefore, even if balanced budget is maintained, government still has to keeppaying its debt redemption and interest. This is why it has to keep borrowingand accumulating its debt; that is to say, it is not balanced in an expanded senseof budget. Initial GDP in the model is attained to be 300, while governmentdebt is initially set to be 200. Hence, the initial debt-GDP ratio is around 0.667year. Yet, the ratio continues to increase to 1.473 year at the year 50 in themodel as illustrated by the line 1 in the right diagram of Figure 8. This impliesthe government debt becomes 1.473 years as high as the annual level of GDP.
Remarks: Even if a debt crisis due to the runaway accumulation of debt failsto be observed in the near future, still there exit some ethical reasons to stopaccumulating debts. First, it continues to create unfair income distribution infavor of creditors, that is, bankers and financial elite, causing inefficient allo-cation of resources and economic performances, and eventually social turmoilsamong the poor. Secondly, obligatory payment of interest forces the indebtedproducers to drive incessant economic growth to the limit of environmental car-rying capacity, which eventually leads to the collapse of environment. In short,a debt money system is unsustainable as a macroeconomic system.
Liquidation Policies of Government Debt
Let us now consider how we could avoid such a debt crisis under the currentdebt money system. At the face of the debt crisis as discussed above, supposethat government is forced to reduce its debt-GDP ratio to less than 0.6 by theyear 50, as currently required to all EU members by the Maastricht treaty.
To attain this goal, though, only two policies are available to the government;that is, to spend less or to tax more. Let us consider them, respectively.
18
Policy A: Spend Less
This policy assumes that the government spend 10% less than its equilibriumtax revenues, so that a primary balance ratio is reduced to 0.9 in our economy.In other words, the government has to make a strong commitment to repay itsdebt annually by the amount of 10 % of its tax revenues. Let us assume thatthis reduction is put into action at the year 6. Line 2 of the left diagram ofFigure 9 illustrates this reduction of spending.
Under such a radical financial reform, debt-GDP ratio will begin to getreduced to around 0.65 at the year 25, as illustrated by line 3 of the samediagram, and to around 0.44 at the year 50, as illustrated by line 2 in the rightdiagram of Figure 8. Accordingly, the accumulation of debt will be eventuallycurved as shown byline 2 in the left diagram of Figure 8.

Figure 9: Liquidation Policies: Spend Less and Tax More
Policy B: Tax More (and Spend More)
Among various sources of taxes to be levied by the government such as incometax, excise tax, and corporate tax, let us assume here that excise tax is increased,partly because an increase in consumption (or excise) tax has become a hotpolitical issue recently in Japan. Specifically the excise tax is assumed to beincreased to 10% from the initial value of 5% in our model; that is, 5% increase.Line 1 of the right diagram of Figure 9 illustrates the increased tax revenues.
Out of these increased tax revenues, spending is now reduced by 8.5% torepay the accumulated debt. Though spending is reduced in the sense of primarybalance, it has indeed increased in the absolute amount, compared with theoriginal equilibrium spending level, as illustrated by line 2 of the same rightdiagram of Figure 9. Accordingly the government needs not be forced to reducethe equilibrium level of budget.
As a result this policy can also successfully reduces debt as illustrated byline 3 of the same diagram up to the year 25, and further up to the year 50 asillustrated by line 3 in the left diagram of Figure 8.
19
Triggered Recession and Unemployment
These liquidation policies seem to be working well as debt begins to get reduced.However, the implementation of these policies turns out to be very costly to thegovernment and its people as well.
Let us examine the policy A in detail. At the next year of the implementationof 10 % reduction of a primary balance ratio, growth rate is forced to drop tominus 2 %, and the economy fails to sustain its full capacity aggregate demandequilibrium of line 1 as illustrated by line 2 in Figure 10. Compared with themostly equilibrium path of line 1, debt-reducing path of line 2 brings aboutbusiness cycles. Similarly, line 3 indicates another business cycle triggered byPolicy B.

Figure 10: Recessions triggered by Debt Liquidation
Figure 11 (lines 2) shows how this policy of debt liquidation triggers GDPgap and unemployment. GDP gap jumps from 0.3% to 3.9% at the year 7, anincrease of 13 times. Unemployment jumps from 0.5% to 4.8% at the year 7,more than 9 times. In similar fashion, lines 3 indicate another gaps triggeredby Policy B.
In the previous paper [16], unemployment was left unanalyzed. In this sense,the result here is a new finding on the effect of debt liquidation under the currentdebt money system. The reader should understand that the absolute number isnot essential here, because our analysis is based on arbitrary numerical values.Instead, comparative changes in factors need be paid more attention.
Figure 12 illustrates how fast wage rate plummets (line 2 in the left diagram)- another finding in this paper. Concurrently inflation rate plunges to -0.98%from -0.16%, close to 6 times drop, that is, the economy becomes deflationary(line 2 in the right diagram). Lines 3, likewise, indicate another behaviors

These recessionary effects triggered by the liquidation of debt turn out tocross over a national border and become contagious to foreign countries. Figure13 illustrates how GDP gap and unemployment in a foreign country get worsenedby the domestic liquidation policy A (lines 2) and policy B (lines 3). Thesecontagious effects under open macroeconomies are observed for the first time inour expanded macroeconomic model - the third finding in this paper. In thissense, in a global world economy, no country can be free from a contagious effectof recessions caused by the debt liquidation policy in other country.

Liquidation Traps of Government Debt
Under a debt money system, liquidation policy of government dept will beeventually captured into a liquidation trap as follows. The liquidation policyis only implemented with the reduction of budget deficit by spending less orlevying tax; that is; policy A or B in our case. Whichever policy is taken, itcauses an economic recession as analyzed above.

Figure 14: Liquidation Traps of Debt
The immediate effects of recession either by policy A or B are the reduction oftax revenues as illustrated by lines 2 in Figure 14. Eventually revenue reductionwill worsen budget deficit. In other words, policies to reduce deficit result in anincrease in deficit. This constitutes a typical balancing feedback loop, which isillustrated as “Revenues Crisis” loop in Figure 15.
The other effect of recession will be a forced bailout/stimulus package bythe government, which in turn increases government expenditures, worseningbudget deficit again. This adds up a second balancing feedback loop, which isillustrated as “Spending Crisis” loop in Figure 15.

In this way the liquidation policies of government debt are retarded by two

balancing feedback loops of revenues crisis and spending crisis, making up liq-uidation traps of government debt. This indicates that the debt money systemcombined with the traditional Keynesian fiscal policy becomes a dead end as amacroeconomic monetary system.
5 Modeling A Public Money System
We are now in a position to implement the alternative macroeconomic systemdiscussed in the introduction, as proposed by the American Monetary Act, inwhich central bank is incorporated into a branch of government and a fractionalreserve banking system is abolished. Let us call this new system a public moneysystem of open macroeconomies. Money issued under this new system plays arole of public utility of medium of exchange. Hence the newly incorporated in-stitution may be appropriately called the Public Money Administration (PMA)in this paper.
Under the new system, transactions of only government, commercial banksand the public money administration (formally the central bank) need be revisedslightly. All domestic models of a public money system of open macroeconomiesas well as foreign exchange and balance of payment are supplemented to the ap-pendix of this paper. Let us start with the description of the revised transactionsof the government.
Government
• Balanced budget is assumed to be maintained; that is, a primary balanceratio is unitary. Yet the government may still incur deficit due to the debtredemption and interest payment.
• Government now has the right to newly issue money whenever its deficitneeds to be funded. The newly issued money becomes seigniorage inflowof the government into its equity or retained earnings account.
• The newly issued money is simultaneously deposited with the reserve ac-count of the Public Money Administration. It is also booked to its depositsaccount of the government assets.
• Government could further issue money to fill in GDP gap.
Revised transaction of the government is illustrated in Figure 35 in the appendix,where green stock box of deposits is newly added to the assets.
Banks
Revised transactions of commercial banks are summarized as follows.
• Banks are now obliged to deposit a 100% fraction of the deposits as therequired reserves with the public money administration. Time depositsare excluded from this obligation.
23
• When the amount of time deposits is not enough to meet the demandfor loans from producers, banks are allowed to borrow from the publicmoney administration free of interest; that is, former discount rate is nowzero. Allocation of loans to the banks will be prioritized according tothe public policies of the government. (This constitutes a market-orientedissue of new money. Alternatively, the government can also issue newmoney directly through its public policies to fill in GDP gap as alreadydiscussed above.)

Figure 16: Required Reserve Ratios
Line 1 in Figure 16 illustrates theinitial required reserve ratio of 5%in our model. We have here as-sumed three different ways of abolish-ing a fractional reserve banking sys-tem. Line 2 shows that a 100% frac-tion is immediately attained in thefollowing year of its implementation,while line 3 illustrates it is attainedin 5 years. Line 4 indicates it is grad-ually attained in 10 years, startingfrom the year 6. In our analysis be-low, 100% fraction will be assumed tobe attained in 5 years as a represen-tative illustration of fractional behaviors.
Public Money Administration (Formerly Central Bank)
The central bank is now incorporated as one of the governmental organizationswhich is here called the Public Money Administration (PMA). Its revised trans-actions become as follows.
• The PMA accepts newly issued money of the government as seigniorageassets and enter the same amount into the government reserve account.Under this transaction, the government needs not print hard currency,instead it only sends digital figures of the new money to the PMA.
• When the government want to withdraw money from their reserve ac-counts at the PMA, the PMA could issue new money according to therequested amount. In this way, for a time being, former central banknotes and government money coexist in the market.
• With the new issue of money the PMA meets the demand for money bycommercial banks, free of interest, according to the guideline set by thegovernment public policies.
Under the revised transactions, open market operations of sales and pur-chases of government securities become ineffective, simply because government

debt gradually diminishes to zero. Furthermore, discount loan is replaced withinterest-free loan. This lending procedure becomes a sort of open and publicwindow guidance, which once led to the rapid economic growth after world warII in Japan [7]. Accordingly, interest incomes from discount loans and govern-ment securities are reduced to be zero eventually. Transactions of the publicmoney administration are illustrated in Figure 37 in the appendix, with greenstock boxes of seigniorage assets and government reserves being added.
6 Behaviors of A Public Money System
Liquidation of Government Debt
Under the public money system of open macroeconomies, the accumulated debtof the government gets gradually liquidated as demonstrated by line 4 in theleft diagram of Figure 17, which is the same as the left diagram of Figure 8except the line 4. Recollect that line 1 is a benchmark debt accumulation of

the mostly equilibria under the debt money system, while lines 2 and 3 are thedecreasing debt lines when debt-ratio are reduced under the same system. Nownewly added line 4 indicates that the government debt continues to decline whena 100% fraction ratio is applied in 5 years, starting at the year 6. The othertwo cases of attaining the 100% fractional reserve discussed above, that is, in ayear or 10 years, reduce the debts exactly in a similar fashion. This means thatthe abolishment period of a fractional level does not affect the liquidation of thegovernment debt, because banks are allowed to fill in the sufficient amount ofcash shortage by borrowing from the PMA in the model.
It is shown in Figure 18 that the liquidation of government debt (line 4) isperformed without triggering economic recession contrary to the case of debtmoney system (lines 2 and 3). To observe these comparisons in detail, let usillustrate GDP gap ratios and unemployment rates in Figure 19, in which thesame line numbers apply as in the above figures. The liquidation of govern-ment debt under the public money system (line 4) can be said to be far betterperformed than the current debt system because of its accomplishment withoutrecession and unemployment.

Figure 20: Wage Rate and Inflation
Moreover, Figure 20 illustrates that wage rate and inflation rates (lines 4)stay closer to the rates of mostly equilibria. Accordingly, the liquidation of debtunder the public money system can be said to be attained without reducing
26
wage rate and setting off inflation.Furthermore, the liquidation of debt under the public money system is not
contagious to foreign countries as illustrated by lines 4 in Figure 21. That is,GDP gap and unemployment in a foreign country (lines 4) remain closer to theiralmost equilibria states (lines 1).

Figure 21: Foreign Recessions are Not Triggered
Debt Crises can be Subdued!
In sum, the pubic money system is, from the results of the above analyses,demonstrated as a superior alternative system for liquidating government debtin a sense that its implementation does not trigger recessions and unemploymentboth in domestic and foreign economies. In other words, looming debt crisescaused by the accumulation of government debt under a current debt moneysystem can be thoroughly subdued without causing recessions, unemployment,inflation, and contagious recessions in a foreign economy.
7 Public Money Policies
The role of a newly established public money administration under a publicmoney system is to maintain a monetary value, similar to the role assigned tothe central banks under the debt money system. Keynesian monetary policyunder the debt money system controls money supply indirectly through the ma-nipulation of required reserve ratio, discount ratio, and open market operations.Accordingly its effect is after all limited, as demonstrated by a failure of stim-ulating the prolonged recessions in Japan during 1990s through 2000s with theadjustment of the interest rates, specifically with zero interest rate policies.
Compared with these ineffective Keynesian monetary and fiscal policies, pub-lic money policies we have introduced here are simpler and more direct; that is,they are made up of the management of the amount of public money in circula-tion through governmental spending and tax policies. Interest rate is no longerused by the public money administration as a policy instrument and left to bedetermined in the market.

Figure 22: Public Money Policies
More specifically, our public money policies consist of three balancing feed-back loops as shown in Figure 22. Anti-recession policy is taken in the case ofeconomic recession to fill in a GDP gap; that is, government spends more thantax revenues by newly issuing public money. On the other hand, in the case ofinflationary state, anti-inflation policy of managing public money is conductedsuch that public money in circulation is sucked back by raising taxes or cuttinggovernment spending. As a supplement to this policy in the case of an unusu-ally higher inflation rate that is overshooting a maximum tolerable level, a stepdown policy of budgetary restructure will be carried out so that a head of thepublic monetary administration is forced to resign for his or her mismanagementof holding a value of public money.
Recession
Let us now examine in detail how anti-recession policy help restore the economy.For this purpose a recession or GDP gap is purposefully produced by changingthe value of Normal Inventory Coverage from 0.1 to 0.5 months and OutputRatio Elasticity (Effect on Price) from 3 to 1, as illustrated in the left diagramof Figure 23.
To fill a GDP gap under such a recessionary situation, let us continue tonewly issue public money by the amount of 5 annually for 20 years, startingat t=7. The right diagram of Figure 23 confirms that the GDP gap now getscompletely filled in. More specifically, Figure 24 demonstrates how GDP gapratio and unemployment rate caused by this recession (lines 1) are recovered bythe public money policy as illustrated by lines 2.

Figure 24: GDP Gap and Unemployment Recovered
Inflation
As shown above, so long as a GDP gap exists, an increase in the governmentexpenditure by newly issuing public money can restore the equilibrium by stim-ulating the economic growth. Yet, this money policy does not trigger a pricehike and inflation as illustrated by lines 2 in Figure 25 in comparison with lines1 of GDP gap.
Yet, inflation could occur if government happens to mismanage the amountof public money. To examine the case, let us take a benchmark equilibriumstate attained by the public money policy as above (lines 2), then assume thatthe government overly increases public money to 15 instead of 5 at t=7 for25 years in the above case. This corresponds to a continual inflow of moneyinto circulation. Under such situations, Figure 25 shows how price goes up andinflation rate jumps to 1.3% (line 3) from the level of 0.3% attained by thepublic money policy (line 2), 4 times hike, at the year 9.
The inflation thus caused by the excessive supply of money also triggers aGDP gap of 5% at the year 12 (or -3.1% of economic growth or recession), andan unemployment rate of 7.7% at the year 13 as illustrated by lines 3 in Figure26.
Persistent objection to the public money system has been that government,once a free-hand power of issuing money is being endowed, tends to issue moremoney than necessary, which tends to bring about inflation eventually, though

history shows the opposite [17]. The above case could be unfortunately onesuch example. With the introduction of anti-inflationary policy, however, thistype of inflation can be easily curbed by the decrease in public money. Letus define maximal inflation as a maximum tolerable inflation rate set by thegovernment. For instance, it was set to be 8% in [16], as suggested by theAmerican Monetary Act. Then, anti-inflationary policy works such that if aninflation rate approaches to the maximal level and a tolerable gap decreases tozero, the amount of public money will be reduced to curb the inflation throughthe decrease in government spendings and/or the increase in taxes.
Step Down
What will happen if the tolerable gap becomes negative; that is, current in-flation rate becomes higher than the maximal inflation? This could occur, forinstance, when the incumbent government tries to cling to the power by unnec-essarily stimulating the economy in the years of election as history demonstrates.Business cycle thus spawned is called political business cycle. “There is someevidence that such a political business cycle exits in the United States, and theFederal Reserve under the control of Congress or the president might make thecycle even more pronounced [6, p.353].” Indeed Figure 27, obtained from theabove analysis of inflation, shows how business cycles could be caused by themismanagement of the increase in public money (line 3) when no GDP gap ex-
30
ists (line 2). This could be a serious moral hazard lying under the public moneysystem.

Figure 27: Business Cycles caused by Inflation under No GDP Gap
Proponents of the central bank may take advantage of this cycle as an excusefor establishing the independence of the central bank from the intervention bythe government. How can we avoid the political business cycle, then, withoutresorting to the independence of the central bank? As a system dynamics re-searcher, I suggest an introduction of the third balancing feedback loop of StepDown as illustrated in Figure 22. This loop forces, by law, a head of the PublicMoney Administration to step down in case a tolerable gap becomes negative;that is, an inflation rate gets higher than its maximum tolerable rate. Then anewly appointed head is obliged to restructure a budgetary spending policy tostabilize a monetary value. The stability of a public money system depends onthe legalization of a forced step down of the head of the public money adminis-tration.
Conclusion
Money is, by Aristotle (384 - 322 BC), fiat money as legal tender and has beenhistorically created either as public money or debt money. Current macroe-conomies in many countries are built on a debt money system, which, however,failed to create enough amount of money to meet an increasing demand forgrowing transactions. Gold standard failed in 1930s and was replaced withgold-dollar standard after World War II, which alas failed in 1971. Then cur-rent dollar standard was established, allowing free hand of creating money bycentral banks, from which, unfortunately, current runaway government debt has
31
been derived. The accumulation of debt will sooner or later lead to impassesof defaults, financial meltdown or hyper-inflation; in other words current debtmoney system is facing its systemic failure.
Under such circumstances it is shown that it becomes very costly to save thecurrent debt money system by reducing government debt and debt-GDP ratio;that is, a liquidation process of debt inevitably triggers economic recessions andunemployment of both domestic and foreign economies.
An alternative system, then, is presented as a public money system of openmacroeconomies as proposed by the American Monetary Act in which onlygovernment can issue money with a full reserve banking system. It is shownthat under the public money system government debt can be liquidated withouttriggering recession, unemployment and inflation.
Finally, in place of the current Keynesian monetary and fiscal policies, publicmoney policies are introduced, consisting of three balancing feedback loops ofanti-recession policy, anti-inflation policy and restructuring policy of step downof a head of PMA (Public Money Administration). Public money policies thusbecome simpler and can affect directly to the workings of the economy.
Accordingly, from a viewpoint of system design, a public money systemof macroeconomies as proposed by the American Monetary Act seems to beworth being implemented if we wish to avoid impasses such as defaults, financialmeltdown and hyper-inflation. 8.
8This implementation might bring about fortunate by-products. A debt money system ofthe current macroeconomy has been pointed out to constitute a root cause of unfair incomedistribution between haves and haves-not, wars due to recessions, and environmental destruc-tion due to a forced economic growth to pay interest on debt. Accordingly, a public moneysystem remove the root cause of these problems and could be panacea for solving them. Dueto the limited space, further examination will be left to the reader
