John Maynard Keynes · Economics
Keynes’s prescription that when private demand collapses, the government should spend to fill the gap - even on seemingly wasteful projects - to restart the economy.
Keynes’s diagnosis pointed to a clear, if radical, cure. If a depression is caused by a collapse in total spending - households too frightened to consume, businesses too pessimistic to invest - then the way out is to restore spending. And if the private sector will not spend, then the one actor large enough to fill the gap is the government. By spending directly, the government can inject demand into the economy, put the unemployed back to work, and - through the multiplier - set off a chain reaction of renewed activity. The state becomes the spender of last resort.
Where does the money come from when tax revenues have collapsed in a recession? Keynes’s answer broke a sacred taboo: the government should borrow and run a budget deficit during the downturn. Trying to balance the budget in a slump - raising taxes or cutting spending to match falling revenue - only removes more demand and deepens the depression. Instead, government should spend counter-cyclically: deficits in bad times to support demand, then surpluses in good times to pay down the debt and cool an overheating boom. The budget should be balanced over the cycle, not every year.
Keynesian fiscal policy works through two distinct channels, and distinguishing them resolves much of the confusion - and answers some of the objections - about government ‘managing the economy.’ The first and less appreciated channel is the automatic stabilisers: features of the tax-and-spending system that counteract the cycle on their own, with no new decision required from anyone. When a recession hits and incomes fall, tax revenues automatically drop (people earn less, so they pay less tax, and progressive taxes fall more than proportionally), and government spending automatically rises (more people claim unemployment benefits, welfare, and other support) - so the government’s budget swings automatically toward deficit in a downturn, cushioning the fall in private demand without any politician lifting a finger. In a boom the reverse happens: revenues swell and benefit payments shrink, automatically pulling demand out of an overheating economy. These stabilisers are quietly Keynesian by design, built into the structure of the modern welfare state, and they are powerful precisely because they are automatic - they act instantly, in exactly the right direction, scaled to the severity of the downturn, and immune to the political and timing problems that plague deliberate intervention.
This is the opening of the lesson. The rest — the dialogue, the primary source, and the recall — is in the app.
You learned that Keynes urged government spending to fight slumps. Explain why he thought even ‘wasteful’ spending could help, and one serious risk of the policy, in your own words.
