This paper identifies sharp bounds on the mean treatment response and average treatment effect under the assumptions of both concave monotone treatment response (concave-MTR) and monotone treatment selection (MTS). We use our bounds and the US National Longitudinal Survey of Youth to estimate...

In this study, we examined the differences between smoking and drinking in regard to their associations with socioeconomic factors among about 7,000 Japanese workers. Using microdata from nationwide surveys in Japan, we estimated bivariate probit models to jointly explore how smoking and...

This paper investigates why so many people are premium payment defaulters or dropouts from the national pension system using household-level data from a Japanese Government Survey. The major results can be summarized as follows: (1) the dropout probability of younger cohorts does not differ...

In Japan, economic stagnation due to the lack of aggregate demand has hit the regional health insurance system and this affects most retired pensioners. The fiscal state of insurers in rural areas deteriorated. This paper aims to investigate whether the regional disparities in medical levies per...

A theoretical curiosity remains in the Huggett [1993] model as to the possible existence of a unique and degenerate stationary distribution of agent types. This coincides with the possibility that an equilibrium individual state space may turn out to be trivial in the sense that every agent...

In this paper we develop a two-country global monetary economy where a monetary equilibrium exists because of fundamentaldecentralized trade frictions ? a Lagos-Wright search and matching friction. In the decentralized markets (DM), the terms of trade can be determined either by bargaining or by...

This study investigates what factors determine students’ academic performance in five major economies in East Asia, using the dataset from the 2007 survey of Trends in International Mathematics and Science Study (TIMSS). We explicitly consider initial maturity differences, endogeneity of class...

Our study employs an OLG model under which political strengths of different generations (the working and retirees with and without children) determine the distribution of the fiscal burden between the generations, including the future generation. We investigate the relationship between the...

As the return to education (and possibly also parental income) is uncertain, and given that the work a child does covertly for his own parents, and transfers between parents and children, are private information, the government should make school enrollment compulsory, set a legal limit...
