It is known that on some social choice and economic domains, a social choice function is coalition strategy-proof if and only if it is Maskin monotonic (e.g. Muller and Satterthwaite, 1977). This paper studies the foundation of those results. I provide a set of conditions which is sufficient for...

This paper develops an overlapping-generations model with nominal wage rigidities and examines the welfare effects of debt policy when unemployment exists. Issues of public debt stimulate aggregate consumption demand and create employment. Future generations then face both increased wage incomes...

This paper studies the incentive compatibility of solutions to generalized indivisible good allocation problems introduced by Sonmez (1999), which contain the well-known marriage problems (Gale and Shapley, 1962) and the housing markets (Shapley and Scarf, 1974) as special cases. In particular,...

This paper reexamines the paradoxical aspect of the electronic mail game (Rubinstein, 1989). The electronic mail game is a coordination game with payoff uncertainty. At a Bayesian Nash equilibrium of the game, players cannot achieve the desired coordination of actions even when a high order of...

We consider full-truthful Nash implementation, which requires that truth telling by each agent should be a Nash equilibrium of a direct revelation mechanism, and that the set of Nash equilibrium outcomes of the mechanism should coincide with the f -optimal outcome. We show that restricted...

Although the Keynesian multiplier effect of public works is criticized for lack of a microeconomic foundation, it is still taught in most undergraduate courses and believed to be useful for policy makers. However, it has a serious fallacy even if we accept the consumption function. This note...

This paper studies the application of the notion of secure implementation (Cason, Saijo, Sjostrom, and Yamato, 2006; Saijo, Sjostrom, and Yamato, 2007) to the problem of allocating indivisible objects with monetary transfers. We propose a new domain-richness condition, termed as minimal richness. We...

This study is an empirical attempt to investigate the effects of balance sheet deterioration of Japanese firms and banks during the 1990s on credit allocation using the Short-term Economic Survey of Enterprises. This survey includes a unique item: the proportion of firms perceiving the lending...

A group of agents are waiting for their job to be processed in a facility. We assume that each agent needs the same amount of processing time and incurs waiting costs. The facility has two parallel servers, being able to serve two agents at a time. We are interested in finding the order to serve...

This paper studies the possibility of strategy-proof rules yielding satisfactory solutions to matching problems. Alcalde and Barber_ (1994) show that efficient and individually rational matching rules are manipulable in the one-to-one matching model. We pursue the possibility of strategy-proof...
