We use the framework of random matching games and develop a two society model to analyze the interaction of societies with different social norms. Each agent repeatedly faces two different coordination games. A social norm of a society is a mode of behavior - strategy - which is adopted by a...

This paper studies the effects of 'price-matching' policies in the Bertrand oligopoly model. If one or more consumers incur enforcement costs to utilize price-matching clauses, the unique equilibrium outcome is the competitive one.

This paper completely characterizes two public ownership solutions in convex production economies, known respectively as the Proportional Solution (PR), and the Equal Benefit Solution (EB), by adopting the axioms Moulin (1990a,b) discussed and introducing two other axioms, Pareto Independence...

This paper examines the implementation of two public ownership solutions in convex production economies with differentiable production functions. The two public ownership solutions we focus on are the proportional and equal benefit solutions. Two "natural" mechanisms which doubly implement the...

This paper examines the implementation of various solutions in differentiable concave production economies with one privately owned input, one output, and publicly owned production technology. The public ownership solutions we focus on are the Proportional Solution (PS) and the Equal Benefit...

This paper establishes a B-core existence result for normal form TU games.

Succeeding Dutta, Sen and Vohra (1995) and Saijo, Tatamitani and Yamato (1997), we define two types of natural mechanisms quantity and price-quantity types, in convex production economies, and characterize the class of Pareto subsolutions doubly implementable in Nash and strong Nash equilibria...

This paper considers an incumbent firm that is faced with a potential entrant in a vertically differentiated market. It demonstrates than an incumbent firm cannot prevent entry through product proliferation because of a commitment problem.
