For the game of complete information with multiple principals and multiple common agents discussed by Prat and Rustichini (2003), we construct a general set of equilibrium transfers which implement any efficient outcome as a weakly truthful equilibrium, and the subset of such equilibria that are Pareto optimal for the principals. We provide conditions under which the general set completely char...

In general partition function form games, the recursive core coalition structure may be either coarser or finer than the one that maximizes the social surplus. Moreover, the recursive core structure is typically different from the one predicted by the α-core. We fully implement the recursive core for general games, including non-superadditive games where the grand coalition does not form in equ...

We develop a tractable dynamic general equilibrium model of oligopolistic competition with a continuum of heterogeneous industries. Industries are exposed to aggregate and industry-specific productivity shocks. Firms in each industry set value-maximizing state-contingent markups, taking as given the behavior of all other industries. When consumers are risk-averse, industry markups are countercy...

The aim of this paper is determination of an optimal policy rule for Iranian economy from an Islamic perspective. This study draws on an Islamic instrument known as the Musharakah contract to design a dynamic stochastic general equilibrium model. In this model the interest rate is no longer considered as a monetary policy instrument and the focus is on the impact of economic shocks on the Dynam...

The formulation of market equilibrium problems as mixed complementarity problems (MCP) permits integration of bottom-up programming models of the energy system into top-down general equilibrium models of the overall economy. Despite the coherence and logical appeal of the integrated MCP approach, implementation cost and dimensionality both impose limitations on its practical application. A comp...

In a two-period pure exchange economy with financial assets, a temporary financial equilibrium is an equilibrium of the current spot and security markets given forecasts of future prices and returns. The temporary equilibrium model can then be interpreted as a Walrasian model where preferences depend on prices. This idenfication implies, among other consequences, the generic determinateness of ...

Definitions of sequential equilibrium and perfect equilibrium are given in games of imperfect recall. Subtleties regarding the definition are discussed. JEL Classification numbers: C70, D81.

The paper focuses on regional trade agreements and economic co-operation and develops a new appropriate approach to study their impact on growth and trade. The approach is based on an endogenous trade-growth theory and novelly specified in an economic integration (expenditure) framework which is the conceptual foundation of regional trade agreements. Importantly, it also appropriately takes int...

Extending the notion of contractual pricing introduced by Makowski and Ostroy (2003) to economies with moral hazard, this paper develops a model of team formation and organized competition with three main contributions. Firstly, a team’s organization is defined as an allocation of (public or private) commodities together with incentive compatible actions and information to its members. Secondly...

We study an alternating offers bargaining model in which the set of possible utility pairs evolves through time in a non-stationary, but smooth manner. In general, there exists a multiplicity of subgame perfect equilibria. However, we show that in the limit as the time interval between two consecutive offers becomes arbitrarily small, there exists a unique subgame perfect equilibrium. Furthermo...
