We develop a frictional labor market model with multiple regions and heterogeneous firms to study how frictions impeding labor mobility across space affect the joint allocation of labor across firms and regions. Bringing the model to matched employer-employee data from Germany, we find that...

U.S. inflation has recently surged, with inflation reaching its highest readings since the early 1980s. We examine the drivers of this rise in inflation, focusing on supply chain disruptions, labor supply constraints, and their interaction. Using a calibrated two-sector New Keynesian DSGE model...

In a collaborative project with ten central banks, we have investigated the causes of the post-pandemic global inflation, building on our earlier work for the United States. Globally, as in the United States, pandemic-era inflation was due primarily to supply disruptions and sharp increases in...

We answer the question posed by the title by specifying and estimating a simple dynamic model of prices, wages, and short-run and long-run inflation expectations. The estimated model allows us to analyze the direct and indirect effects of product-market and labor-market shocks on prices and...

Financial integration generates macroeconomic spillovers that may require international monetary policy coordination. We show that individual central banks may set nominal interest rates too low or too high relative to the cooperative outcome. We identify three sufficient statistics that...

We show that reducing the probability of a trade war promotes long-term importer-exporter relationships that ensure provision of high-quality inputs via incentive premia. Empirically, we introduce a method for distinguishing between these Japanese versus spot-market (i.e., American)...
