Ordinally single-peaked preferences are distinguished from cardinally single-peaked preferences, in which all players have a similar perception of distances in some one-dimensional ordering. While ordinal single-peakedness can lead to disconnected coalitions that have a "hole" in the ordering,...

Based on a result due to Ray and Vohra showing the possibility of inefficiency due to a coalition formation in an international emission reduction game, we consider a possibility of negotiation preceding the negotiation stage, and by means of an example, indicate that the efficiency is restored....

We model 'money buys access' informational lobbying as a commitment from the policy-maker to observe a lobby's verifiable evidence only upon receiving an access fee. We specifically examine the policy-maker's optimal access fees in the presence of two strictly competing lobbies. Our novel method...

A conclave is a voting mechanism in which a committee selects an alternative by voting until a sufficient supermajority is reached. We study experimentally welfare properties of simple three-voter conclaves with privately known preferences over two outcomes and waiting costs. The resulting game...

This paper investigates the coordination of bargaining activities among labor unions in a Multinational Enterprise (MNE) with plants in different countries. Making use of a threestage game where the parties sequentially decide whether o coordinate negotiations, it derives the bargaining regimes...

This paper develops a two-country multi-frictional model where the freeze on liquidity access to commercial banks in one country raises unemployment rates via credit rationing in both countries. The expenditure-switching channel, whereby asymmetric monetary shocks traditionally lead to negative...

This report contains three separate papers, each addressing selected issues concerning natural gas policy and security of gas supply in Europe. The over-arching themes are vulnerability (to supply disruptions, to supplier pricing power) and fragmentation; and measures designed to overcome them,...

We examine the effects of money priming and solidarity on individual behavior in three simple experiments: dictator game, ultimatum game, and prisoner's dilemma. Our study comprises two money treatments and two neutral (control) treatments. Additionally, we control for the strength of social...

We analyze a model of strategic network formation prior to a Manea (2011) bargaining game: ex-ante homogeneous players form costly undirected links anticipating expected equilibrium payoffs from the subsequent network bargaining. Assuming patient players, we provide a complete characterization...

We provide a new proof of the non-emptiness of approximate cores of games with many players of a finite number of types. Earlier papers in the literature proceed by showing that, for games with many players, equal-treatment cores of their "balanced cover games", which are non-empty, can be...
