Statistical Discrimination and Duration Dependence in the Job Finding Rate (w/ Gregor Jarosch) [Draft \ Slides]  - R&R Review of Economic Studies

We propose an equilibrium search model to quantify the implications of employer discrimination against the long-term unemployed for job finding rates and long-term unemployment. In our framework, dynamic selection on unobservables endogenously generates statistical discrimination at the interview, or callback stage. In the estimated model, interview invitations for observationally equivalent workers decline by 50% as unemployment duration increases from 1 to 8 months, in line with a string of recent resume audit studies. Yet long-term unemployment and job-finding rates at all durations are almost identical in a full information benchmark where employers do not discriminate. Interviews lost to statistical discrimination impact individual job-finding rates solely if they would have counterfactually led to jobs. We show that such false negatives are rare because firms only discriminate when they anticipate being unable to form a viable match. Statistical discrimination is thus largely a response to dynamic selection rather than a cause of true duration dependence.
 


Assortative Matching and Income Inequality: A Structural Approach (w/ Shu Lin Wee) [Draft \ Slides]

Income inequality across households has risen dramatically in the last 40 years. At the same time, there have been significant changes in the determinants of household income, including educational attainment, the skill premium, and marital sorting patterns. We link these phenomena through an equilibrium model of investment in schooling, marriage, and household search. The present discounted value of search in the labor market at the household level determines the surplus generated by each marriage for each education pair, determining equilibrium educational attainment and the degree of marital sorting. In this environment, we show that the direction of marital sorting depends on the degree of search complementarities in the labor market. Using an estimated version of the model, we construct counterfactual income distributions under changing primitives (i.e., marital preferences and skill premia) that let the degree of sorting, educational attainment, and inequality respond to movements in those primitives.



The Productivity Gains from Household Insurance [Draft \ Slides] (currently being revised, draft available upon request)

This paper studies the effects of household insurance on aggregate productivity. If workers are risk averse and couples can pool their income, then under plausible assumptions on preferences, those with higher wage spouses search for higher wage jobs that are harder to obtain, but are also more productive. I calibrate the model to match evidence on search at the household level and compare realized output to counterfactual output in an economy where couples cannot pool income. Preliminary results suggests that aggregate output is up to thirty percent larger in an economy when couples can share risk and search jointly in the labor market. 



Sectoral Shocks and Move Unemployment [Draft]
(previously circulated under "A Multisector Equilibrium Search Model of Labor Reallocation")

This paper develops a multisector search model in which workers choose their sectors in response to sector-specific and idiosyncratic shocks. Unemployed workers can search for work in their sector of last employment, or become ``move unemployed,'' spending extra time in unemployment to reach a new sector. Sectoral shocks induce net movements of labor into relatively productive sectors, while idiosyncratic worker shocks ensure that gross intersectoral flows through unemployment are always positive, a prediction consistent with the data. I use the model to test the sectoral shifts hypothesis (Lilien (1982)) in the context of the Great Recession in which the construction sector experienced a relatively large shock. In a two-sector calibration of the model to construction and non-construction, I find that sectoral dispersion shocks have no impact on aggregate unemployment. While they increase net mobility, this increase is accomplished through a change in the composition of gross flows rather than their level. The results suggest that, a priori, we should not expect sectoral shocks to generate unemployment fluctuations.
