This paper introduces a new concept for full implementation that takes into account agents' preferences for understanding how the "process" works. We assume that the agents have an intrinsic preference for honesty in the sense that they dislike the idea of lying when it does not influence their...

This paper incorporates behavioral economics into implementation theory. We use mechanisms that are strictly detail-free. We assume that each agent dislikes telling a white lie when such lying does not serve her/his material interest. We present a permissive result wherein by using just a single...

We model a timing game of bubbles and crashes a la Abreu and Brunnermeier (2003), in which arbitrageurs compete with each other to beat the gun in a stock market. However, unlike Abreu and Brunnermeier, instead of assuming sequential awareness,the present paper assumes that with a small...

We investigate the finitely repeated prisoners' dilemma with explicit contractual devices. We show that full collusion can be achieved by incentivizing the players' final period of play with small fines. Our incentivizing modality is the penance contract, by which a player is penalized if (and...

This paper incorporates social psychology into implementation theory, where an uninformed principal manipulates a dynamic decision-making process without employing any tailored contractual device. We demonstrate the principal's mind-control method through which he can effectively utilize social...

This paper incorporates social psychology into implementation theory. Real individuals care not only about their material benefits but also about their social influence in terms of obedience and conformity. Using a continuous time horizon, we demonstrate a method of manipulating the...

We investigate the adverse selection problem where a principal delegates multiple tasks to an agent. We characterize the virtually implementable social choice functions by using the linking mechanism proposed by Jackson and Sonnenschein (2007) that restricts the message spaces. The principal...

This paper introduces a new concept of market mechanism design into general economic environments with finite but many traders, where multiple objects are traded and any combination of complements and substitutes is permitted. The auctioneer randomly divides traders into multiple groups. Within...

We analyze the stock market by modeling it as a timing game among arbitrageurs for beating the gun. We assume that (1) arbitrageurs are behavioral with a small probability, (2) the bubble soft-lands, and (3) the postcrash price increases as the X-day is postponed. Due to these assumptions, the...
