This paper uses a battery of calibrated and estimated structural models to determine the causal drivers of the negative correlation between output and aggregate uncertainty. We find the transmission of uncertainty shocks to output is weak, while aggregate uncertainty endogenously responds to...

The Cobb-Douglas matching function is ubiquitous in search and matching models, even though it imposes a constant matching elasticity that is unlikely to hold empirically. Using a general constant returns to scale matching function, this paper first derives analytical conditions that determine...
