Does Macroeconomic Theory Influence Macroeconomic Policy?
| Peter Klein |
Not really, according to John Wood’s History of Macroeconomic Policy in the United States (Routledge, 2008). As David Wheelock notes in his EH.Net review:
Wood argues that U.S. fiscal and monetary policy have been remarkably consistent over the decades and largely uninfluenced by macroeconomic theory. Economists have rationalized more than influenced policy, Wood contends, and the direction of influence between economic theory and practice is primarily from the latter to the former.
This is of course the classic explanation for the spread of Keynesianism after 1936: rather than proposing a new approach to macroeconomic policy, the General Theory simply rationalized the massive deficit-spending and easy-money policies already in place (and long desired by disreputable economists such as Foster and Catchings).
