Conventional wisdom holds that, in the long run, the Phillips curve is vertical. We re-examine the relationship between inflation and unemployment in the long run, using quarterly US data from 1952 to 2010, and state-of-the art econometric methods. Using a band-pass filter approach, we find...

We examine the implications of changes in the skill distribution on the equilibrium matching process and the job finding rate, using a directed search approach. Worker abilities are selected from a distribution while firms face heterogeneous entry costs and direct their job offers to workers. We...

We develop an open economy general equilibrium model, with auction-based directed search unemployment, to study the interactions of trade and unemployment. The theory ascribes all outcomes purely to the fundamentals of technology and endowment. If countries differ by endowment, trade makes both...

We examine the relationship between inflation and unemployment in the long run, using quarterly US data from 1952 to 2010. Using a band-pass filter approach, we find strong evidence that a positive relationship exists, where inflation leads unemployment by some 3 to 3 1/2 years, in cycles that...

We examine the implications of worker heterogeneity on the equilibrium matching process, using a directed search model. Worker abilities are selected from a general distribution, subject to some weak regularity requirements, and the firms direct their job offers to workers. We identify...
