Temporary agency work (TAW) is believed to facilitate the matching between firms and on-the-job searchers. This leads to shortening of the unemployment and job search duration. On the other hand, firms that hire temporary workers have less incentive to train them, which makes it difficult for...

In view of the finding that debtors are likely to be more obese than nondebtors, we investigate whether interpersonal differences in body mass are, as in the case of debt behavior, related to those in time discounting and time discounting anomalies. The effects of time discounting on body mass...

This paper investigates whether the level of happiness and integrated process of changes in happiness are the same. Using the daily data of two waves of four and six months each, we found that the level of happiness is stationary, whereas the integrated process of changes is non-stationary with...

Most studies have not distinguished delay from intervals, so that whether the declining impatience really holds has been an open question. We conducted an experiment that explicitly distinguishes them, and confirmed the declining impatience. This implies that people make dynamically inconsistent...

Employing the Japan-U.S. international survey, this study analyzed the cause of rising perception of the widening income gap in Japan. Between these two countries, their distinct value judgments on the substance of gap influence their recognition. Japanese have negative perception of the income...

This paper attempts to estimate the causal effect of public capital stock on production using Japanese prefectural data. We first articulate the difficulty of consistently estimating the regional-level production function with public capital due to the endogeneity of the public capital stock...

Recent studies report that productivity increases under tournament reward structures than under piece rate reward structures. We conduct maze-solving experiments under both reward structures and reveal that overconfidence is a significant factor in increasing productivity. Specifically, subjects...

Extant research has found that an individual's happiness is relative with respect to income, suggesting that it rises with own income and falls as the income of a reference group increases. Some recent studies emphasize that the effect of relative income is mediated by the extent to which people...

We examined whether the knowledge that your private donation has a large number of potential recipients causes you to give more or less. We found that the people with blood type O are more likely to have donated blood than those with other blood types, by using a Japan's nationally...
