It is much more efficient than other similar ships.’ (Project engineer)

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

You bet!

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

What happens if we eliminate increases
in all sources of economic growth?
(starting in 2010 over 10 years)
• Consumption
• Investment
• Government
• Trade
• Population/labour
• Productivity
A no growth disaster

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