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...

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 discusses and develops "non-welfaristic" arguments on distributive justice, mainly basing upon J. Rawls and A.K. Sen, and formalizes, in cooperative production economies, "non-welfaristic" distribution rules as game forms. First, it conceptualizes Needs Principle that the distribution...

Succeeding Dutta, Sen and Vohra (1995) and Saijo, Tatamitani and Yamato (1995), we define several conditions of natural mechanisms in production economies, and proposed two types of natural mechanisms, that is, the quantity and price-quantity types.

In this paper, we shall provide a theoretical overview of what are the chief implications of fucusing institutions and economic systems, what are the main sources of their evolution, how are their evolutionary paths affected by various economic factors. In the latter half, we shall provide a...

This article is devoted to a survey of results for differential games obtained through Viability Theory. We recall the basic theory for differential games (obtained in the 1990s), but we also give an overview of recent advances in the following areas : games with hard constraints, stochastic...

Network users can choose among different security solutions to protect their data. Those solutions are offered by competing providers, with possibly different performance and price levels. In this paper, we model the interactions among users as a noncooperative game, with a negative externality...
