Recent empirical work shows that judicial dependence can explain high levels of corruption. This paper examines how the dependence of judiciaries influences corruption at different levels of the government in a model where the central government, low-level officials, and the judiciary are...

We run a large-scale natural field experiment to evaluate alternative strategies to enforce compliance with the law. The experiment varies the text of mailings sent to potential evaders of TV license fees. We find a strong alert effect of mailings, leading to a substantial increase in...

Economists draw important lessons for modern development from the medieval Maghribi traders who, according to Greif, enforced contracts multilaterally through a closed, private-order coalition'. We show that this view is untenable. The Maghribis used formal legal mechanisms and entered business...

We analyze the relationship between legal institutions, innovation and growth. We compare a rigid (law set ex-ante) legal system and a flexible one (law set after observing current technology). The flexible system dominates in terms of welfare, amount of innovation and output growth at...

The medieval Champagne fairs are widely used to draw lessons about the institutional basis for long-distance impersonal exchange. This paper re-examines the causes of the outstanding success of the Champagne fairs in mediating international trade, the timing and causes of the fairs' decline, and...

Decisions concerning marriage, fertility, participation, and the education of children are explained using a two-stage game-theoretical model. The paper examines the effects of (i) family law (cost of obtaining a divorce, alimony, availability of quasi-marriages such as PACS in France, and civil...

In this paper, we analyze a class of models in which there are interjurisdictional spillovers among heterogeneous jurisdictions, as illustrated for instance by CO2 emissions that affect the global environment. Each jurisdiction's emissions depend upon the local stock of private capital. Capital...

We examine “Forward Guidance Contracts”, which make central bankers’ utility contingent on the precision of interest-rate forecasts for some time. Such Forward Guidance Contracts are a exible commitment device and can improve economic performance when the economy is stuck in a liquidity...

In currency exchange markets, there is a conflict between individual decisions and the socially optimal solution. Whereas agents have a coordination motive to take the same position, at the social level effective market coordination per se is not socially valuable, and the central bank aims at...

A 1999 reform allowed Italian Mayors to partially substitute a more accountable source of tax revenue (the property tax) with a less transparent one (a surcharge on the personal income tax). Theoretical analysis suggests this should give incompetent Mayors a less costly way to hide themselves,...
