Eric Tymoigne and Randall Wray's (T&W, 2013) defense of MMT leaves the MMT emperor even more naked than before (excuse the Yogi Berra-ism). The criticism of MMT is not that it has produced nothing new. The criticism is that MMT is a mix of old and new, the old is correct and well understood,...

This paper compares Cambridge and neo-Kaleckian growth theory. Both are members of the post-Keynesian approach to growth and distribution, but the Cambridge model is a hybrid of Keynesian and classical features whereas the neo-Kaleckian model is Keynesian. The Cambridge approach assumes full...

This paper examines the implications of a currency union for monetary policy. The formation of a currency union worsens the inflation-unemployment tradeoff, so that leaving the inflation target unchanged at its pre-currency union level generates increased unemployment. Geographically based...

I thank Tom Michl for his insightful and gracious note (Michl 2013) pointing out a mistake in my paper (Palley 2013a) on fiscal policy in post-Keynesian economics. Despite correctly deriving the analytic condition (ibid., p. 85, footnote 6), I incorrectly drew the IS-ZZ diagram in figure 2,...

This paper excavates the set of ideas known as modern monetary theory (MMT). The principal conclusion is that the macroeconomics of MMT is a restatement of elementary well-understood Keynesian macroeconomics. There is nothing new in MMT's construction of monetary macroeconomics that warrants the...

This paper modifies the textbook income-expenditure model to properly account for imports. This modification causes government spending to have an even larger relative impact compared to tax cuts than conventionally thought. It also shows that increased government spending can have a smaller...

The causal relation between saving and investment has momentous implications for fiscal policy. If saving causes investment, this lends support for policies of fiscal austerity. Neither the national income accounts nor economic theory can resolve issues of causality. This paper presents a VAR...
