We present a simple, positive model in which regulatory enforcement is a 2-stage process. In the first stage firms are subject to random inspection. The inspection yields a noisy signal of the firm's true performance. Only if the signal exceeds some critical or "trigger" value is the firm...

Class action suits are a legal device by which similarly injured individuals can collectively obtain compensation through the justice system. Damage averaging occurs when the compensation awarded by the court to individual members is partly or completely determined by the average damage of the...

The detection of dangerous road sites is usually performed using empirical methods which focus on observed accident frequencies and/or proportions of accidents with a given feature. The most widely used detection tools have an empirical Bayes (EB) background. The EB approaches rely on the...

A voting situation, in which voters are asked to rank all candidates pair by pair, induces a tournament and a weighted tournament, in which the strenght of the majority matters. Each of these two tournaments induces in turn a two-player zero-sum game for which different solution concepts can be...

The usual Condorcet Criterion says that if an alternative is ranked ahead of all other alternatives by an absolute majority of voters, it should be declared the winner. The following partial extension of this criterion to other ranks is proposed: If an alternative is consistently ranked ahead of...

The problem in which some agents joint together to realize a set of projects and must decide how to share its cost may be seen as a cooperative cost game. In many instances, total cost may naturally be decomposed into joint costs and costs that are specific to individual agents. We show that the...

Consider a small developing economy with a manufacturing sector opened to international trade, and an agricultural sector having limited, not to say any, access to world markets. We modify the Grossman and Helpman's influence-driven model of trade policy formation to allow for an endogenously...
