Collateral Constraints, Wage Rigidity, and Jobless Recoveries

The Great Recession has drawn attention to the importance of macro-financial linkages. In this paper I explore the joint role of imperfections in labor and financial markets for the cyclical adjustment of the labor market. I show that jobless recoveries emerge when, upon exiting a recession, firms are faced with deteriorating credit conditions. On the financial side, collateral requirements affect the cost of borrowing for firms. On the employment side, hiring frictions and wage rigidity increase the need for credit, making the binding collateral constraint more relevant. In a general equilibrium business cycle model with search and matching frictions, I illustrate that tightening credit conditions calibrated from data negatively affect employment adjustments during recovery periods. Wage rigidity substantially amplifies this mechanism, generating empirically plausible fluctuations in employment and output.

Macroeconomic Long-Run Effects of the German Minimum Wage when Labor Markets are Frictional

This paper analyzes the introduction of the German minimum wage in 2015 in a structural model geared to quantitatively assess its long-run economic effects. We first employ a simple neoclassic model where wages equal their marginal product, then extend this model to two sector economy, and finally introduce search and matching frictions. Even though all model variants remain highly stylized, they yield quantitative insights on the importance of different mechanisms and channels through which minimum wages affect outcomes in the long run. In this framework, the minimum wage has a strong negative effect on employment. When sectors are differently affected by the minimum wage, sectoral relative price changes play an important quantitative role. Other labor market policies and institutions are important for the transmission of minimum wage policy on labor market market outcomes.

Housing market and labor market search

Current models fail to concurrently account for several important empirical regularities in the housing and labor markets. I augment the Diamond-Mortensen-Pissarides (DMP) search and matching model of the labor market with a housing market characterized by search and matching frictions, integrating both markets in a coherent macroeconomic model. The model provides a framework to explain how shocks and frictions which originate in the labor market spill over into the housing market and vise versa. The model accounts for procyclical, serially correlated real estate values, rental rates and expected real estate appreciation. Further, it accounts for increases in wages, housing costs and willingness to commute as a result of increases in geographic amenities. The model is also consistent with the empirical relationship between vacancy rates in the housing market and separation rates in the labor market. Simulations demonstrate that certain land-use policies can mitigate permanent shocks to labor productivity and the level of geographic amenities.

FISCAL RULES AND UNEMPLOYMENT

This paper shows how fiscal policy affects unemployment in a New Keynesian model with search and matching frictions and distortionary taxation. The model is estimated using US data that includes labor market flows and distinct fiscal instruments. Several findings stand out. First, unemployment multipliers for spending and consumption tax cuts are substantial, even though output multipliers turn out to be less than one. Second, multipliers for labor tax cuts are small. Third, fiscal rules enhance the positive effects of discretionary fiscal policy. However, these expansionary effects on the multipliers are modest compared to earlier studies.

Search Frictions, Efficiency Wages and Equilibrium Unemployment

This paper explores the decomposition of equilibrium unemployment into involuntary and frictional components using a model that combines efficiency wages with search and matching frictions in the labour market. In deriving our results we generalise the celebrated Solow Condition, expressing the wage as the sum of a pure efficiency wage component and a component that reflects search frictions. Using standard values of calibrated parameters, we find that the bulk of unemployment is involuntary

UNEMPLOYMENT BENEFITS AND MATCHING EFFICIENCY IN AN ESTIMATED DSGE MODEL WITH LABOR MARKET SEARCH FRICTIONS

To explain the high and persistent unemployment rate in the United States during and after the Great Recession, this effort develops and estimates a dynamic stochastic general equilibrium model with search and matching frictions and shocks to unemployment benefits and matching efficiency. It finds that unemployment benefits play an important role in the cyclical movement of unemployment through their effects on labor demand, a channel overlooked in previous studies. From the second half of 2008 to 2011, extended unemployment benefits may have increased the overall unemployment rate by one percentage point. In contrast, matching efficiency changes had less effect on the cyclical movement of unemployment for the same period, but significantly slowed down the recovery after 2012.

IMMIGRATION AND UNEMPLOYMENT: A MACROECONOMIC APPROACH

This paper analyzes the effects of an unanticipated increase in immigration in a macroeconomic model with search and matching frictions. It shows how an immigration shock can lead to a temporary increase in unemployment under a variety of conditions and that this is qualitatively consistent with the responses from a VAR estimated on postwar US data.
