This paper examines the trade-off between the length of treatment days and the units of service provided per day for elderly patients in the context of the initiative taken by the Ministry of Health and Welfare of Japan to discourage lengthy hospital treatment and/or stay by elderly patients. By...

In this study we use data from the National Longitudinal Survey of Youth (NLSY). We estimate the relationship between high school graduation, and alcohol and marijuana use among the sample of high school students. We also estimate these students' demand determinants for each of these substances. Our...

Our study shows that the household production theory illuminates the behavior of households in the allocation of time and consumption expenditures. Among the noteworthy findings derived from our data, the various household non-market time allocations (consequently, market labor supply) cannot be...

The study focuses on the influence of labor, capital, R&D, technological knowledge, and other factors influencing labor productivity in different manufacturing industries. The study also examines the competitiveness of these manufacturing industries in the Japanese market. The results indicate that...

The aim of this paper is to examine the impact of labor market conditions, represented by male civilian unemployment rates, on seven major categories of crime. We propose a theoretical model from which the positive macro relationship between the unemployment rate and the crime rate is explicitly...

Japanese annual time series data covering the period 1951 to 1982 reveals that changes in the program of social security retirement benefits have substantial influence on personal saving and retirement behavior. The empirical results show that social security retirement benefits depress personal...

Using Japanese annual time series data covering the period from 1946to 1982, this paper shows that social security wealth depresses personal savings. The effect was a reduction of approximately 143 thousand yen per capita wealth in real terms from 1970 to 1980. However, declining labor force...

The estimated elasticity of the probability of retirement with respect to social security retirement benefits declines as individuals age. The negative impact of social security retirement benefits on full-time workers is much greater than the impact on part-time workers for all age groups. Earnings...

The model presented in this paper emphasizes the importance of the mother's nutritional intake as a determinant of infant health. Using cross-sectional market averages for 1980 and 1981 in Japan, we find that the nutrient intake of the mother during pregnancy is a potential determinant of neonatal...

Using a multanornial logistic approach, we analyze the inter-dependencies among the labor force participation decisions of married women an Japan. These decisions are working part-time,working full-time, being unemployed (in the labor market but unable to find work), and not participating. Our focus...

In this paper, we attempt to resolve the drawbacks in previous studies of the labor supply of women in Japan. We hypothesize here that the response to the socioeconomic factors that influence the decision to work varies among different groups of women, and we estimate separately the labor supply of...

Previous studies of female labor force participation in Japan often show that the estimates of female wage rates are "negative" in their single-equation models of labor supply. Based on the common belief that the substitution effect dominates the income effect for female labor supply, to disentangle...

A strong and negative correlation between married women's labor force participation and fertility has been witnessed in Japan in past decades. Relative to empirical studies of a traditional single equation on female labor supply, there exist few econometric studies dealing explicitly witha possible...
