On his blog, Roger Farmer advertizes his new book, “Prosperity for All,” and argues that governments should stabilize asset prices:
Following the Great Stagflation of the 1970s, economists backtracked and revived the classical economic theory that had dominated academic economics for a hundred and fifty years, beginning with Adam Smith in 1776 and culminating in the business cycle theory described by Keynes’s contemporary Arthur Pigou in his 1927 book, Industrial Fluctuations. That backtrack was a big mistake. It is time to realize that much, but not all, of Keynesian economics is correct. …
In my book Prosperity for All: How to Prevent Financial Crises, … I do not conclude that more government spending is the right way to cure a depression. Instead, I argue for a new policy in which central banks and national treasuries systematically intervene in financial markets to prevent the swings in asset prices that have such debilitating effects on all of our lives.
The control of asset prices will seem like a bold step to some, but so too did the control of the interest rates by the Open Market Committee of the Federal Reserve System when it was first introduced in 1913. We do not have to accept hyperinflations of the kind that occurred in 1920s Germany. Nor should we be content with the 50% unemployment rates that plague young people in Greece today. By designing a new institution, based on the modern central bank, we can and must ensure Prosperity for All.
And in another post:
The New Keynesian agenda is the child of the neoclassical synthesis and, like the IS-LM model before it, New Keynesian economics inherits the mistakes of the bastard Keynesians. It misses two key Keynesian concepts: (1) there are multiple equilibrium unemployment rates and (2) beliefs are fundamental. My work brings these concepts back to center stage and integrates the Keynes of the General Theory with the microeconomics of general equilibrium theory in a new way.
