In this paper we incorporate a labor market with matching frictions and wage rigidities into the New Keynesian business cycle model. In particular, we analyze the effect of a monetary policy shock and investigate how labor market frictions affect the transmission process of monetary policy. The...

This paper studies the role of sticky prices for the monetary transmission mechanism, using disaggregated industry-level data from 205 US industries. There is substantial heterogeneity in the output responses of industries to monetary policy surprises. I show that an industry's response to...

The secession of Southern Sudan from the mother nation of Sudan was a direct result of political agreement known as the Comprehensive Peace Agreement (CPA). It was expected by the totalitarian government of Northern Sudan that it can contain the civil war between the Sudan Popular Liberation...

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...

The empirical effectiveness of economic policies that operate theoretically through similar channels differs substantially. We document this fact by comparing an easy-to-grasp expectations-based policy, unconventional fiscal policy, with a policy whose implications are harder to understand by...
