In this article, we investigate the role of several types of educational mismatch in explaining labour market transitions of workers with secondary and higher education. We focus on transitions from employment to unemployment and on job changes, to assess whether mismatch is a temporary or a...

Using newly digitized unemployment insurance claims data we construct a historical monthly unemployment series for U.S. states going back to January 1947. The constructed series are highly correlated with the Bureau of Labor Statics' state-level unemployment data, which are only available from...

This paper examines how economic insecurity and cultural anxiety have triggered different dimensions of the current populism in the United States. Specifically, I exploit two quasi-natural experiments, the Great Recession and the 2014 Northern Triangle immigrant in ux, to investigate the effects...

We reassess the role of vacancies in a Diamond-Mortensen-Pissarides style search and matching model. In the absence of free entry long lived vacancies and endogenous separations give rise to a vacancy depletion channel which we identify via joint unemployment and vacancy dynamics. We show...

In the standard macroeconomic search and matching model of the labor market, there is a tight link between the quantitative effects of (i) aggregate productivity shocks on unemployment and (ii) unemployment benefits on unemployment. This tight link is at odds with the empirical literature. We...

This paper provides a microeconomic model of matching which implies that the standard, reduced form approach, is misspecified. A simple model is analysed (with help-wanted/employment-needed advertising) where the matching rate depends not only on the stocks of unemployed and vacancies in the...

This paper offers an alternative theory for the increase in unemployment and wage inequality experienced in the United States over the past two decades. In my model firms decide the composition of jobs and then match with skilled and unskilled workers. The demand for skills is endogenous and an...

The matching function describes the flow of job creation as a function of the stocks of unemployed and vacancies. Most empirical work tries to identify such a relationship by regressing the flow of matches (aggregated over the month) on the stocks of unemployment and vacancies measured at the...

This paper analyses how the levels of unemployment and vacancies affect the rate at which unemployed workers find employment -- the worker-firm `matching function'. In particular we test the robustness of previous empirical work by checking whether we obtain the same estimated function using...

This paper models equilibrium trading patterns when marketplaces exist and goods are differentiated. When first visiting the market, a buyer samples a stock of goods. If fortunate, the buyer matches with and purchases one of these goods and then exits the market. If an initial match does not...
