Educational Financing and Lifetime Earnings

Review of Economic Studies 2004 71(4), 1189-1216
This paper formulates and estimates a dynamic programming model of optimal educational financing decisions. The main purpose of the paper is to measure the effect of short-term parental cash transfers, received during school, on educational borrowing and in-school work decisions, and on post-graduation lifetime earnings. The estimated parameters of the model imply that parental cash transfers do not significantly influence post-graduation lifetime earnings. Long-term factors such as family background and prior human capital investments are more important. Parental cash transfers do, however, significantly determine the decision to borrow or work during school and the level of lifetime consumption. Copyright 2004, Wiley-Blackwell.

Job Mobility and the Market for Lawyers

Journal of Political Economy 1998 106(1), 147-171
This paper studies the life cycle career choices of law school graduates using unique data from the University of Michigan Law School. The model assumes that these graduates act according to the optimal solution of a dynamic optimization problem in which they sequentially choose among five employment sectors. The employment sectors are differentiated by pecuniary and nonpecuniary returns, promotion and dismissal probabilities, and the extent of transferability of human capital. the estimation of the model reveals a self‐selection mechanism, based on unobserved heterogeneity in abilities and expected future returns, which plays a critical role in reproducing the sector‐specific nonmonotonic separation hazards observed in the data. The underlying self‐selection mechanism also has implications for policy interventions in the market for lawyers, such as loan forgiveness programs.

Doctors without Borders? Relicensing Requirements and Negative Selection in the Market for Physicians

Journal of Labor Economics 2005 23(3), 437-465 open access
Relicensing requirements for professionals who move across borders are widespread. In this article, we measure the effects of occupational licensing by exploiting an immigrant physician retraining assignment rule. Instrumental variables and quantile treatment effects estimates indicate large returns to acquiring an occupational license and negative selection into licensing status. We also develop a model of optimal license acquisition that, together with the empirical results, suggests that stricter relicensing requirements may lead not only to practitioner rents but also to lower average quality of service in the market for physicians.

Immigration, Search, and Loss of Skill

Journal of Labor Economics 2003 21(3), 557-591
This article develops and estimates an on‐the‐job search model of the entry of highly skilled immigrants from the former Soviet Union into the Israeli labor market. The estimated parameters of the model, together with information on the wages of immigrants from earlier waves, imply that, on average, immigrants can expect lifetime earnings to fall short of the lifetime earnings of comparable natives by 57%. Of this figure, 14 percentage points reflect frictions associated with nonemployment and job distribution mismatch, and 43 percentage points reflect the gradual adaptation of imported schooling and experience to the local labor market.

Classification Error in Dynamic Discrete Choice Models: Implications for Female Labor Supply Behavior

Econometrica 2009 77(3), 975-991
Two key issues in the literature on female labor supply are (i) whether persistence in employment status is due to unobserved heterogeneity or state dependence, and (ii) whether fertility is exogenous to labor supply. Until recently, the consensus was that unobserved heterogeneity is very important and fertility is endogenous. Hyslop (1999) challenged this. Using a dynamic panel probit model of female labor supply including heterogeneity and state dependence, he found that adding autoregressive errors led to a substantial diminution in the importance of heterogeneity. This, in turn, meant he could not reject that fertility is exogenous. Here, we extend Hyslop (1999) to allow classification error in employment status, using an estimation procedure developed by Keane and Wolpin (2001) and Keane and Sauer (2005). We find that a fairly small amount of classification error is enough to overturn Hyslop's conclusions, leading to overwhelming rejection of the hypothesis of exogenous fertility.
