In The triumph of monetarism, Brad De Long wrote in the Journal of Economic Perspectives—Volume 14, Number 1—Winter 2000—Pages 83–94 that today’s new Keynesian" macroeconomists would include in any list of their key ideas and premises the five following propositions that:
- The key to understanding real fluctuations in employment and output is to understand the process by which business cycle-frequency shocks to nominal income and spending are divided into changes in real spending and changes in the price level.
- Under normal circumstances, monetary policy is a more potent and useful tool for stabilization than is fiscal policy.
- Business cycle fluctuations in production are best analysed from a starting point that sees them as fluctuations around the sustainable long-run trend (rather than as declines below some sustainable potential output level).
- The right way to analyse macroeconomic policy is to consider the implications for the economy of a policy rule, not to analyse each one- or two-year episode in isolation as requiring a unique and idiosyncratic policy response.
- Any sound approach to stabilization policy must recognize the limits of stabilization policy—the long lags and low multipliers associated with fiscal policy; the long and variable lags and uncertain magnitude of the effects of monetary policy.
De Long then went on to argue that the above research programme is the macroeconomic research programme of Milton Friedman in the mid-20th century.
Utopia, you are standing in it!
