Olivier Blanchard offers a summary of things learned from a recent conference on the future of macroeconomics. I found this point puzzling:
The crisis made it clear that there are many distortions relevant for macroeconomics, many more than we thought earlier.
In particular, he cites agency theory and the role of finance. If this is what we have learned, who are ‘we’? The idea that credit market frictions play an important role in macroeconomic fluctuations and monetary policy has been widely recognized. The current Fed chairman, in fact, is a co-author of a widely cited paper on the role of the “financial accelerator” within a fairly New Keynesian framework. In fact, here is a list of influential papers (by no means exhaustive), the date of publication, the number of citations (according to Google Scholar), and the author(s):
