Persistent Inequality

(with Dilip Mookherjee), Review of Economic Studies 70, 369-393, 2003.

SummaryWhen human capital accumulation generates pecuniary externalities across professions, and capital markets are imperfect, persistent inequality in utility and consumption is inevitable in any steady state. 

Coalitional Power and Public Goods

(with Rajiv Vohra), Journal of Political Economy 109, 1355-1384, 2001.

Summary. We study the provision of public goods when all agents have complete information and can write binding agreements. The focus is on coalition formation as a potential source of inefficiency.

Bargaining Power and Enforcement in Credit Markets

(with Garance Genicot), Journal of Development Economics 79, 398-412, 2006.

Summary. In a credit market with enforcement constraints, we study the effects of a change in the outside options of a potential defaulter on the terms of the credit contract, as well as on borrower payoffs. The results crucially depend on the allocation of “bargaining power” between the borrower and the lender. We prove that there is a crucial threshold of relative weights such that if the borrower has power that exceeds this threshold, her expected utility must go up whenever her outside options come down. But if the borrower has less power than this threshold, her expected payoff must come down with her outside options.  These disparate findings within a single model permit us to interpret existing literature on credit markets in a unified way.
