We investigate possible racial discrimination in the context of discretionary parole release. We develop a rational choice model of release whereby a parole board must balance parolees' risk of violation with the cost of not releasing prisoners who may not violate their parole. A color-blind...

Economists generally assume the existence of sufficient institutions to sustain a market economy and tax the citizens. However, this starting point cannot easily be taken for granted in many states, neither in history nor in the developing world of today. This paper develops a framework where...

The economic literature on enforcement is generally pessimistic concerning the use of legal aid. In this Paper we show that legal aid can be part of optimal law enforcement. The rationale behind our result is that with legal aid, in a system with legal or judicial error, both guilty and innocent...

In cooperation with Lex Mundi member law firms in 109 countries, we measure and describe the exact procedures used by litigants and courts to evict a tenant for non-payment of rent and to collect a bounced check. We use these data to construct an index of procedural formalism of dispute...

I study data on bribes actually paid by individuals to public officials, viewing the results through a theoretical lens that considers the implications of trust networks. A bond of trust may permit an implicit quid pro quo to substitute for a bribe, which reduces corruption. Appropriate networks...

Two literatures in political economy argue that differences in political institutions help explain variation in the fiscal performance of countries. They indentify electoral systems and institutions that structure the formation of the budget as important determinants of the budget deficit. In...

In a Case Law regime Courts have more flexibility than in a Statute Law regime. Since Statutes are inevitably incomplete, this confers an advantage to the Statute Law regime over the Case Law one. However, all Courts rule ex-post, after most economic decisions are already taken. Therefore, the...

We investigate the origin and evolution of the legal institution of citizenship from a political economy perspective. We compile a new data set on citizenship laws across countries of the world which documents how these institutions have evolved in the postwar period. We show that, despite a...

The cost of enforcing contracts is a key determinant of market performance. We document this point with reference to the credit market in a model of opportunistic debtors and inefficient courts. According to the model, improvements in judicial efficiency should reduce credit rationing and...

While confounding factors typically jeopardise the possibility of using observational data to measure peer effects, field experiments offer the possibility of obtaining clean evidence. In this Paper we measure the output of four randomly selected groups of individuals who were asked to fill...
