Focusing on the legal protection of minority shareholders in Japan, which suggests that manager‐owned firms are better governed than corporation‐owned firms, this study presents a new test of two dividend models: the substitute model and the outcome model. In support of the latter, I find that manager‐owned firms pay higher dividends than corporation‐owned firms. The paper also examines the association between ownership by the largest shareholder and dividend payments. I find an inverted U‐shaped relationship for manager‐owned firms and a U‐shaped relationship for corporation‐owned firms between them. These results can be explained by the benefits and drawbacks of concentrated ownership. 相似文献

We estimate labor losses caused by spam mails and input these estimated values into a production function, while also estimating
damage to the Gross Domestic Product (GDP) in Japan. As a result, we have found that spam mails decreased the Japanese GDP
by about 500 billion yen in 2004. This marginal negative effect of spam mail to the GDP increased with the progress of broadband
in 2000. Moreover, from the result of a social simulation conducted by the authors, the amount of damage is projected to reach
1% of the Japanese GDP by 2010, unless adequate countermeasures are taken against spam mails. This projection provides a statistical
fundamental to several theoretical analyses of spam mails. 相似文献

This study examines how the demand and supply of healthcare services have responded to the expansion of health insurance coverage in Vietnam by using biyearly provincial panel data from 2006 to 2014. The results of our analysis indicate significant progress towards universal health coverage (UHC) in Vietnam, with the expansion of health insurance coverage being accompanied by increases in admissions and inpatient days. However, some concerns remain. Our findings show a positive response of supply capacity only in terms of doctors and nurses at higher‐level hospitals (provincial hospitals), and none in other relevant aspects. Moreover, we find no positive response of the number of outpatient visits. Another concern is the issue of financial protection. The decline in out‐of‐pocket payments is not significant throughout our observation period, suggesting that lowering the cost of healthcare is not straightforward and that the expansion of health insurance coverage alone cannot achieve this. We believe that the Vietnamese experience has valuable implications for other emerging and developing countries, considering that the expansion of health insurance coverage is likely to increase utilization of healthcare services significantly and that the supply side needs to be prepared for the increase. 相似文献

This study investigates empirically the role of wealth in the behavior of Japanese households from two standpoints. One is concerned with what types of wealth are relevant in consumption decision by households. The other is which component of consumption spending is affected by wealth. We find that the liquid financial wealth appears as a significant explanatory variable in expenditure function of many commodity groups as well as total consumption. It turns out that variations of liquid wealth are responsible for about one third of the change in aggregate consumption in the boom period starting from the middle of 1980s. 相似文献
