We develop a measure of static misallocation that separates uncertainty from misallocation generated by tax-like distortions. In the Finnish firm-level data, uncertainty accounts for the majority of ex post misallocation and explains a strong decreasing age-dependent trend in it. To understand...

An establishment can improve its productivity by hiring workers from more productive establishments. Then, how important is worker reallocation for aggregate productivity growth? To study this question, I develop a general equilibrium model where knowledge transmits as workers reallocate from...

With non-homothetic preferences, a monopolistic competition equilibrium is inefficient in the way inputs are allocated towards production. This paper quantifies a gains from trade component that is present only when reallocation is properly measured in a setting with heterogeneous firms that...

I develop a method to measure and separate the production misallocation caused by failures in factor markets versus financial markets. When I apply the method to rice farming villages in Thailand I find surprisingly little misallocation. Optimal reallocation would increase output in most...
