On the State of Macroeconomics

In a paper, Ricardo Reis defends macroeconomics against various critiques. He concludes: I have argued that while there is much that is wrong with macroeconomics today, most critiques of the state of macroeconomics are off target. Current macroeconomic research is not mindless DSGE modeling filled with ridiculous assumptions and oblivious of data. Rather, young macroeconomists are doing vibrant, varied, and exciting work, getting jobs, and being published. Macroeconomics informs...

Economics is not the same as applied statistics although the latter can help clarify, at least to some extent, the empirical relevance of economic theories....

True Cognitive Dissonance

There is gold in Asia, at least gold of the intellectual variety for anyone who wishes to see it. The Chinese offer us perhaps the purest view of monetary conditions globally, where RMB money markets are by design tied directly to “dollar” behavior. It is, in my view, enormously helpful to obsess over China’s monetary system so as to be able to infer a great deal about the global monetary system deep down beyond the...
