Several empirical studies have challenged tournament theory by pointing out that (1) there is considerable pay variation within hierarchy levels, (2) promotion premiums only in part explain hierarchical wage differences and (3) external recruitment is observable on nearly any hierarchy level. We...

It is well-known that, in static models, minimum wages generate positive worker rents and, consequently, inefficiently low e?ort. We show that this result does not necessarily extend to a dynamic context. The reason is that, in repeated employment relationships, ?rms may exploit workers’...

When several plaintiffs file individually a lawsuit against the same tortfeasor, the resolution of the various cases through repeated trials produces positive informational externalities, which benefit to the later plaintiffs (since there exist precedents, jurisprudence...). Thus, the first...

In this paper, we study the dynamics of legal rules in a model with two nation-states playing a non cooperative game. For each country, changing the legal system is a costly process. At the same time, the existence of different legal systems is also costly for all nation-states. We show that...

We develop a 2-country model of legal dynamics in which each country's social welfare depends generally on its actual law, its culturally ideal one, its technologically efficient one and the actual law of the other country. In our model, countries are better off when all these laws coincide....

This paper elaborates on a basic model of mass tort litigation, highlighting the existence of positive informational externalities afforded by the discovery process (as a general technology of production of evidences) in order to study when a class action is formed, or when a sequence of...
