Trade liberalization,the exchange rate and job flows in Brazil

Brazil underwent a large trade liberalization process in the 1990s. Over the period, manufacturing employment decreased significantly, generating public debate on the need to revert liberalization. This paper aims to identify the actual effect of trade liberalization on employment, separating it from exchange rate movements using a gross job flow approach. Our novel dataset covers all sectors and formally registered enterprises, and we use new sector specific exchange rate data. Our estimates suggest that greater openness reduce jobs through increased job destruction, with no effect on job creation, but the exchange rate matters also. Depreciations expand the number of jobs in manufacturing by increasing creation, with no effect on destruction.     

Inflation and Welfare in Long‐Run Equilibrium with Firm Dynamics

We analyze the welfare cost of inflation in a model with a cash‐in‐advance constraint and an endogenous distribution of establishments' productivities. Inflation distorts aggregate productivity through firm entry dynamics. The model is calibrated to the U.S. economy and the long‐run equilibrium properties are compared at low and high inflation. When the period over which the cash‐in‐advance constraint is binding is one quarter, an annual inflation rate of 10% leads to a decrease in average productivity of roughly 0.5% compared to the optimum. This decrease is not innocuous: it leads to a doubling of the welfare cost of inflation.
