We study the effect of strengthening CACs in a debt rollover model of a sovereign debt crisis. Conditional on default, there are multiple equilibria: the impact of strengthening CACs depends critically on the prevailing equilibrium. For a subset of equilibria, (i) given a fixed number of...

We examine a “Rotten Kid” model (Becker 1974) where a player with social preferences interacts with an egoistic player. We assume that social preferences are intentionbased rather than outcome-based. In a very general multi-stage setting we show that any equilibrium must involve mutually...

Mitigation and adaptation are the most important strategies in combating global climate change. It is expected that in a post Kyoto world industrialized countries have to engage in greenhouse gas abatement, and to support developing countries in adapting to climate change. Within the framework...

A simple dynamic game is used for analyzing international environmental problems and climate agreements. Different countries are, over time, emitting as well as investing in green technology. In this framework, we can analyze the business-as-usual outcome, short vs. long term agreements,...

We consider games where individual contributions are costly but beneficial to other players, so that contributing nothing is a dominant strategy. Considering that players may be unable to write binding agreements but may make binding unilateral commitments that are conditional on others'...

This note examines how the second chance, when provided to a disadvantaged player, can resolve the prisoner’s dilemma.

Unique-lowest sealed-bid auctions are auctions in which participation is endogenous and the winning bid is the lowest bid among all unique bids. Such auctions admit very many Nash equilibria (NEs) in pure and mixed strategies. The two-bidders' auction is similar to the Hawk-Dove game, which...

Water markets with market power are analysed as multi-market Cournot competition in which the river structure constrains access to local markets and limited resources impose capacity constraints. Conditions for uniqueness are identified. Lerner indices are larger under binding resource...

In this paper we consider the linear quadratic differential game for descriptor systems that have index one. We derive both necessary and sufficient conditions for existence of an open-loop Nash equilibrium

The ultimatum heuristic is a decision-making tendency discernible in graphical plots of mixed-motive noncooperative games. As such, it can serve also as a solution approach, backsolving, predicting and explaining outcomes better than the mainstay Nash equilibrium concept whenever data for the...
