The Trade Restrictiveness Index (TRI) introduced by Anderson and Neary (1994) provided the first theoretically satisfying measure of a countrys tariff structure by overcoming the problem of ad hoc specification of indexing weights and the related index number problem. We observe, however, that...

We characterize asymmetric equilibria in two-stage process innovation games and show that they are prevalent in the different models of R&D technology considered in the literature. Indeed, cooperation in R&D may be accompanied by high concentration in the product market. We show that while such...

Recent work by Pecorino (1998, 1999) and Esteban and Ray (2001) has called into question one of the central propositions of Olson (1965) relating public good provision to group size. Pecorino addresses this issue in a repeated game context, while Esteban and Ray introduce a technology under...

Morgan (2000) has shown that lotteries are potentially an effective mechanism for the provision of public goods. In particular, he has shown that lotteries lead to a level of provision above the level provided by the voluntary contributions mechanism. In this paper, we analyze the effect of...

We analyze simultaneous discrete public good games with incomplete information and continuous contributions. We consider contribution and subscription games. We show that every equilibrium is inefficient. We also provide a sufficient condition for 'contributing zero' to be the unique equilibrium...

A warm-glow motivation for charitable giving has recently been explored as a possible solution to the problem of inefficient private provision of public goods. However, the introduction of warm-glow affects both the efficient level of public good provision as well as the equilibrium level. Hence...
