We study Nash implementation by natural price-quantity mechanisms in pure exchange economies with free-disposal (Saijo et al., 1996, 1999) where agents have weak/strong intrinsic preferences for honesty (Dutta and Sen, 2012). Firstly, the Walrasian rule is shown to be non-implementable where all...

The primary objective of this paper is to examine how and to what extent changes in income tax rates and income tax deductions affect income inequality from longitudinal perspectives, by using microdata from Japanese individuals and households. The findings of this paper could shed light on the...

Conditions α and β are two well-known rationality conditions in the theory of rational choice. This paper examines the implications of weaker versions of these two rationality conditions in the context of solutions to nonconvex bargaining problems. It is shown that, together with the standard...

本論文の前段では，この四半世紀の設備投資研究の展開を理論・実証の両面から振り返った．この間の成果に注目すれば，凸型（二次）の調整費用関数を前提とし，線形の投資関数を導く「q...

Given the framework introduced by Dutta and Sen (2012), this paper offers a comprehensive analysis of (Nash) implementation with partially honest agents when there are three or more participants. First, it establishes a condition which is necessary and sufficient for implementation. Second, it...
