Given the unanticipated nature of the financial collapse in Q3 of 2008, differences across firms in their patterns of seasonal nominal wage adjustment generated heterogeneity in firms’ exposure to downward nominal wage rigidity in Q4 of 2008. I find that exposure to downward nominal wage rigidity generated by firms’ seasonal wage adjustment patterns accounts for 23% of the spike in aggregate job destruction that occurred in Q4 of 2008. In Chapter 2, I present descriptive work with Leland...
