What Causes Recessions?


Noah Smith on the causes of economic recessions:
While the article appears to suggest the superiority of the sticky-price models (and they are indeed superior to real business cycle theory based models), it fails to note that, until recently, most macroeconomic models ignored the role of the financial sector. Financial cycles, in fact, play an enormous role in driving actual business cycles. 

In fact, Robert Lucas himself came around to the conclusion that financial shocks matter:
“As I have written elsewhere, I now believe that the evidence on post-war recessions (up to but not including the one we are now in) overwhelmingly supports the dominant importance of real shocks. But I remain convinced of the importance of financial shocks in the 1930s and the years after 2008. Of course, this means I have to renounce the view that business cycles are all alike!”
