Declining Search Frictions, Unemployment, and Growth Revisited
This paper revisits the conditions under which search models generate balanced growth paths (BGPs)—equilibria where unemployment, vacancies, and job flows remain steady as search frictions decline. Martellini and Menzio (2020) claim that such paths exist only when matches are “inspection goods” and match quality follows a Pareto distribution. We show that these conditions are sufficient but not necessary. Their implementation assumes a strong form of stationarity—requiring the endogenous distribution of match qualities to remain invariant under proportional scaling. This restriction ...

Trading Relationships in the OTC Market for Secured Claims : Evidence from Triparty Repos
We use a new panel data set on intraday transactions of triparty repos (TPR) to study trading relationships in the over-the-counter market. We test the prediction that search frictions lead to relationship formation. We find that TPR trading parties form relationships with a broad number of counterparties but tend to focus their transaction volumes on only a small set of counterparties. We also find that having stable relationships and broader interactions across other funding markets positively shapes the relationships of investors with dealers in the TPR market. Finally, our results suggest ...

Does Exporting Improve Matching? Evidence from French Employer-Employee Data
Does opening a market to international trade affect the pattern of matching between firms and workers? This paper answers this question both theoretically and empirically in three parts. We set up a model of matching between heterogeneous workers and firms in which variation in the worker type at the firm level exists in equilibrium only because of the presence of search costs. When firms gain access to the foreign market, their revenue potential increases. When stakes are high, matching with the right worker becomes particularly important because deviations from the ideal match quickly ...

Taxation, Social Welfare, and Labor Market Frictions
Taking inefficiencies from taxation as given, a well-known public finance literature shows that the elasticity of taxable income (ETI) is a sufficient statistic for assessing the deadweight loss (DWL) from taxing labor income in a static neoclassical framework. Using a theoretical approach, we revisit this result from the vantage point of a general equilibrium macroeconomic model with labor search frictions. We show that, in this context, and against the backdrop of inefficient taxation, DWL can be up to 38 percent higher than the ETI under a range of reasonable parametric assumptions. ...

Non-Linear Employment Effects of Tax Policy
We study the non-linear propagation mechanism of tax policy in a heterogeneous agent equilibrium business cycle model with search frictions in the labor market and an extensive margin of employment adjustment. The model exhibits endogenous job destruction and endogenous hiring standards in the form of occasionally-binding zero-surplus constraints. After parameterizing the model using U.S. data, we find that the dynamic response of employment to a temporary change in the labor income tax is highly non-linear, displaying sizable asymmetries and state-dependence. Notably, the response to a tax ...

Search Frictions, Labor Supply, and the Asymmetric Business Cycle
We develop a business cycle model with search frictions in the labor market and a labor supply decision along the extensive margin that yields cyclical asymmetry between peaks and troughs of the unemployment rate and symmetric fluctuations of the labor force participation rate as in the U.S. data. We calibrate the model and find that cyclical changes in the extent of search frictions are solely responsible for the peak-trough asymmetry. Participation decisions do not generate asymmetry but contribute to the fluctuations in search frictions by changing the size and composition of the pool of ...

The Alpha Beta Gamma of the Labor Market
Using a large panel dataset of US workers, we calibrate a search-theoretic model of the labor market, where workers are heterogeneous with respect to the parameters governing their employment transitions. We first approximate heterogeneity with a discrete number of latent types, and then calibrate type-specific parameters by matching type-specific moments. Heterogeneity is well approximated by 3 types: αs, βs and γs. Workers of type α find employment quickly because they have large gains from trade, and stick to their jobs because their productivity is similar across jobs. Workers of type ...

The Alpha Beta Gamma of the Labor Market
Based on patterns of employment transitions, we identify three different types of workers in the US labor market: α’s β’s and γ’s. Workers of type α make up over half of all workers, are most likely to remain on the same job for more than 2 years and, when they become unemployed, typically find a new job within 1 quarter. Workers of type γ comprise less than one-fifth of workers, have a low probability of staying on the same job for more than 2 years and, when they become unemployed, face a high probability of remaining jobless for more than 1 year. Workers of type β are in ...

Jacks of All Trades and Masters of One: Declining Search Frictions and Unequal Growth
Declining search frictions generate productivity growth by allowing workers to find jobs for which they are better suited. The return of declining search frictions on productivity varies across different types of workers. For workers who are "jacks of all trades" in the sense that their productivity is nearly independent from the distance between their skills and the requirements of their job—declining search frictions lead to minimal productivity growth. For workers who are "masters of one trade" in the sense that their productivity is very sensitive to the gap between their individual ...

The Distributional Impact of the Minimum Wage in the Short and Long Run
We develop a framework with rich worker heterogeneity, firm monopsony power, and putty-clay technology to study the distributional impact of the minimum wage in the short and long run. Our production technology is disciplined to be consistent with the small estimated employment effects of the minimum wage in the short run and the large estimated elasticities of substitution across inputs in the long run. We find that in the short run, a large increase in the minimum wage has a small effect on employment and therefore increases the labor income of the workers who were earning less than the new ...
