Preface Any institutional education would not be completed if it were confined within theoretical
aspects. Every branch of education has become more competed by their practical application
and accomplishment of full knowledge. We shall be benefited by our education if we can
effectively apply the institutional education in practical fields. Hence, we all need practical
education to apply theoretical knowledge in real world. By considering this importance faculty
of economics arranges the Quantitative Methods in Economic Analysis courses for the
students of Masters in International Economics and Finance. As a part of this program my
topic was selected as how effectiveness of the fiscal and monetary.
I tried my best to conduct an effective study by arrange and analysis data. There may be some
mistakes, which are truly unintentional. So, I would request to look at the matter with merciful
mind.

(I).StatementoftheProblems
Under the economic conceptual, namely the IS-LM framework, the government might increase
the income by operate the fiscal expansion policy. The same gold also can occur from themonetary sector. The central bank might choose to increase the money supply level in order to
expand the economic growth. However, the policy manipulation might not able to achieve the
target since some of economic reason. Then, this paper tries to predict that how effectiveness ofthe fiscal and monetary.
(II)Reviewsofliteratureandtheoreticalbackground:One of the economic frameworks, which illustrate the relationship of the macroeconomic
variables, is the IS-Lm framework. The IS-LM framework goes beyond the simple Keynesiancross model of national income determination by adding a monetary sector and allowing for the
simultaneous interactions between investment, the interest rate and the demand for money, and
between saving, income and the demand for money. It is therefore an extremely useful and
versatile model, which can be used to discuss the effects of change in exogenous expenditure,
fiscal policy, monetary policy, and so on. The IS curve shows all the combinations of income
and interest rate at which the market for good and services is in equilibrium, in the sense that
expenditure is equal to output. The consumption is assumed to be a function of measured
income. It is positively related to the income.
C = a + by a > 0, 00
The LM curve is the locus of all the combinations of interest rate and real income at which the
money market is in equilibrium that is the demand for money equal supply of money. It is
assumed that the supply of money is fixed exogenous by the government, i.e. M, = M. At the
equilibrium, it can get that;
Md/P = d+mY-iR
Ms= M.
Ms =M
Ms=Md
Then, it might be able to obtain R as a function of Y;
R=Pd-M+m.Y

(V.3). The Interpretation of the resultAccording the result from equation, even though the current consumption should depend oil the
income by the theory, however, this case, the consumption is just determined by lag consumption
itself. Since the equation (1) is the autoregressive equation, then, the Durbin h statistic is
constructed. From the h statistic, it implies that there is no autocorrelation problem in this model.
By the way, the investment behavior follows as the theory state. It depends on the income level and
also has a negatively related with the interest rate. For the interest rate determinant, it can be
explained by the current income, the rate of change rate of income, and the rate of change rate of
money supply. However, it does not have any related with its lag value. Moreover, it might able to
see the historical simulation of consumption, investment, interest rate, and income from the
diagram as follow

(V.4).Export Forecast:After we got the estimated result, then it might want to test the goodness of fit of model in the
prediction.Hence,
we make the export forecast], by using the date 1986:1to 1988:1.The result is show as:

According the above graph, the simulation model may able to forecast the movement of the
economic variables. Nevertheless, it seems that the power of the prediction is not quite good. Thus,
we might want to confirm the goodness of the model by calculating for the root mean square error,

(V.5).Policy Analysis:Supposed that the government increase the exogenous expenditure by 3 percent, while also increase
the money supply for 1 percent. The result show as follows

(V.6). Interpretation the policy EffectivenessAccording the graph which shown in the section (V.5), it illustrates the effectiveness of the government policy. Inthis case, we let the government increase the government expenditure and also expand the money supply. The result
is consistent with the theoretical background.
We might interpret the result by combining the result in section (V.5) and the theoretical background in
section (V.6) together.

The Fiscal Policy
At the beginning period of time, the autarky equilibrium stays at point A, income stay at ''+- , and interest rate at .
Then, the government injects the government expenditure amount 3 percent in to the economy. This might increase
the aggregate demand. The IS curve shift to the right. The economy moves to point B. At that time, the
consumption will increase to Y01(2650). The interest rate rise up from .(11%) to Rfll (12.75%). The investment
will also increase from 770 to 820. This evidence drive the national income from i,(4100) to Yol (4300).
The Monetary Policy
At the same time, the central bank also injects the money supply into the economy. The LM curve will shit to the
right. The economy moves from point B to C. The consumption level still rises up to 2700. However, the interest rate
will drop to 11.5. These events drive the national income up to 4400, eventually.
(VI).Conclusion
This paper tries to study the effectiveness of the government policy, both of fiscal policy and monetary policy. The
paper use the simulation model to capture the effect of the 3 percent increase in the government expenditure, and
the 1 percent increase un the money supply. By the simulation method, we might able to predict the changing
magnitude of the economic variable, such as consumption, interest rate, investment, and the national income. All
of the information is available in the interpretation part (V.6).
