The economy: a sub-system of the biosphere
The Lisbon strategy for growth and employment
“For Europe to increase living standards, itneeds to accelerate employment andproductivity growth…[and be] as supportiveas possible of growth … to sustain …environmental sustainability.”
GDP = P(1- u)LP: productivity (GDP per employed person)L: labour force (employed plus unemployed)u: rate of unemployment (unemployed/labour force)E: environment/resource impacty: intensity (impact/GDP)

Can we have full employment, no poverty, fiscal balance, reduced GHG emissions without relying on economic growth?

What makes an economy grow?
• Macro demand (what wespend money on):– Consumption– Investment– Government– Trade
• Macro supply (what we canproduce):– Labour– Capital– Productivity

What happens if we eliminate increasesin all sources of economic growth?

‘The real issue is whether it is possible tochallenge the “growth-at-any-cost model”and come up with an alternative that isenvironmentally benign, economicallyrobust and politically feasible.’
Larry Elliot (economics editor)The Guardian Weekly 29th August 2008
A better low/no growth scenarioHow?• New meanings and measures of success• Limits on materials, energy, wastes and land use• Carbon price - more informative prices• Stable population and labour force• More efficient capital stock• Shorter work year• More generous anti-poverty programs• Fewer status goods• More informative advertising• Education for life not just work

Entering the Mainstream“It is possible that the US andEurope will find that…eithercontinued growth will be toodestructive to the environmentand they are too dependent onscarce natural resources, orthat they would rather useincreasing productivity in theform of leisure…
Robert SolowNobel Laureate in Economics
There is no reason at allwhy capitalism could notsurvive with slow or even nogrowth.”(Harper’s Magazine, March 2008)
Policy Directions• Measuring progress• Environment• Population• Reduced work time• Investment, productivity and technology• Consumption• MWG in one country?
‘It may not be possible to increase the production, especially of goods, beyond
limit, because of the environmental damage that this would entail…As society progresses, it is not
unreasonable to expect people to enjoysome of the fruit of that progress
in the form of leisure.’
How should we measure progress?
Joseph Stiglitz Amartya Sen
Environment
Daly’s Three Principles1.Renewable resources: harvest not to
exceed regeneration rate
2.Non-renewable resources: rate ofdepletion not to exceed rate of creationof renewable substitutes
3.Waste emissions: not to exceedassimilative capacity
Policies for limiting throughput
• Limits:– e.g. annual allowable cut, ozone depleting
substances• Taxes:
– e.g. carbon tax• Trading
– e.g. SOx, carbon
Protected areas‘Defined as legally established areas,both land and water, that are regulatedand managed for conservation objectives:include parks, wildlife and forest reserves,wilderness and other areas designated throughfederal, provincial, and territorial legislations.’(NRCan)

Canada’s immigration policy• “Canada’s immigration levels plan for 2010 reflects a long-
term vision for immigration and recognizes the important roleof immigration in Canada’s economic growth and prosperity.”(Annual Report to Parliament on Immigration, 2009)
• In whose interest?–The country of immigration–The country of emigration–The immigrant
Stabilizing Canada’s population
• Low projection: 103,000 economic immigrants/yr• Medium projection: 22,000 economic immigrants/yr• High projection: 0 economic immigrants/yr
reduction in other categories
• Environmental migrants?

Conditions for a successful policy ofreducing work time to reduce unemployment
1. Wage compensation rising2. Changes in work organization3. Train more skilled labour4. Low fixed cost per employee5. Earnings equity6. Standardization of working hours
Consumption and advertising
• Ban advertising in public spaces• Control advertising on the internet• End the commercialization of
childhood• Tax advertising• Introduce a time and resources levy• Put the agencies’ mark on their
work• Introduce statutory regulation of the
advertising industry
Investment, productivity and technology
• Shift investment to priorities of MWG(leisure/recreation, community, publicgoods)
• Limits on throughput: will affectinvestment priorities
• Taxation:– Capital gains and capital tax– Favour investment in throughput efficiency
• Realize productivity gains as reducedhours worked
• Technology:– investment– assessment

Realize productivity gains (Pe)as reduced hours worked (a)
MWG in one country?• Obstacles:
– International trade treaties– Flight of capital and skilled labour
• Opportunities:– Policy support for transformation:
• measures of success• localization• alternative business models• work time
– Individual and community action– International movements for SSE
