We model which special interest groups lobby which policymakers directly, and which employ for-profit intermediaries. We show that special interests affected by policy issues that frequently receive high political salience lobby policymakers directly, while those that rarely receive high...

This is the first study to examine the effect of experiencing a widespread, deadly epidemic on voting behavior. Using data on elections to the U.S House of Representatives and leveraging cross-district variation in HIV/AIDS mortality during the period 1983-1987, we document the effects of the...

Previous research has shown that if countries "merge", (i.e. move to centralized policy choices) the effect is to reduce lobbying. However empirical evidence suggests that this is not always the case. This paper attempts to explain the empirical evidence in a two-jurisdiction political economy...

Interest groups are introduced in a spatial model of electoral competition between two political parties. We show that, by coordinating voting behavior, these interest groups increase the winning set, which is defined as the set of policy platforms for the challenger that will defeat the...

In the last two decades of the XIX century Italy became an industrial country. Historians maintain that this process was affected by the action of some interest groups that pursued both state protection from competition and specific public expenditure programs. Starting from the economic...

The present paper analyzes situations in which groups compete for rents. A major result in the literature has been that there are both cases where larger groups have advantages and cases where they have disadvantages. The paper provides two intuitive criteria which for groups with homogenous...

We analyze a contest between two groups where group members have differing valuations for the contested rent. Generically the pivotal group member with the median valuation of the rent will not act himself but will want to send a group member that has preferences different to her own into the...

Interest groups are introduced in a spatial model of electoral competition between two political parties. We show that the presence of these interest groups increases the winning set, which is the set of policy platforms for the challenger that will defeat the incumbent. Therefore interest...

Recent studies indicate that firms often outsource standard and simple tasks, while keeping complex and important inputs inside their boundaries. This observation is difficult to reconcile with the property rights approach of the firm, which suggests that important components should be...

We report on several experiments on the optimal allocation of ownership rights. The experiments confirm the property rights approach by showing that the ownership structure affects relationship-specific investments and that subjects attain the most efficient ownership allocation despite starting...
