We consider the well-analyzed abatement game (Barrett 1994) and prove that correlation among the players (nations) can strictly improve upon the Nash equilibrium payoffs. As these games are potential games, correlated equilibrium - CE - (Aumann 1974, 1987) cannot improve upon Nash; however we...

In chapter 1, we consider the possibility of Secure Implementation in Production Economies beyond the result provided in the Saijo et al. (2007) paper. We find a large class of SCFs to be securely implementable. The serial SCF and the widely studied Fixed Path SCFs which contains serial SCF as a...

We study incentive compatible profit-sharing rules when output (or profit) is obtained via the joint use of a technology exhibiting decreasing marginal returns. The incentives compatibility criterion we adopt is that of strategy-proofness (SP), arguably the most robust and the most demanding...

This thesis consists of three essays. In the first two essays we assume that the wife earns a lower wage rate than the husband and we analyze intrafamily distributional effects if environmental parameters such as the tax system or divorce regulations change. The third essay evaluates the...

We propose two new axioms of demand responsiveness for additive cost sharing with variable demands. Group Monotonicity requires that if a group of agents increase their demands, not all of them pay less. Solidarity says that if agent i demands more, j should not pay more if k pays less. Both...

We introduce a model of bargaining among groups, and characterize a family of solutions using a Consistency axiom and a few other invariance and monotonicity properties. For each solution in the family, there exists some constant alpha = 0 such that the "bargaining power" of a group is...
