Who bears the burden of social insurance? Evidence from Japanese health and long-term care insurance data 总被引:1,自引:0,他引:1
Kohei Komamura Atsuhiro Yamada 《Journal of the Japanese and International Economies》2004,18(4):565-581
Using the society-managed health insurance data, which is cross-sectional time-series and covers 1670 health insurance societies for seven years (FY1995–2001), we found for the first time in Japan that the majority of the employers' contribution to health insurance is shifting back onto the employees in the form of wage reduction. On the other hand, we cannot find such evidence for the contribution to long-term care insurance using a two-year (FY2000–2001) panel data set. The difference can be theoretically explained by how employees value the contribution relative to social security benefits they enjoy. J. Japanese Int. Economies 18 (4) (2004) 565–581. 相似文献

We extend a second‐generation Schumpeterian growth model to incorporate human capital accumulation to clarify the general equilibrium effects of subsidy policies on human capital accumulation and R&D activities in a unified framework. Despite the conventional argument that subsidies always stimulate these growth‐promoting activities, we find that subsidies asymmetrically affect human capital accumulation and R&D activities. Our theoretical results suggest that research using standard models of human capital might find false negative relationships between education subsidies and economic growth. 相似文献

Underpinned by the framework of the theory of planned behavior, this study uncovered the beliefs that could influence individuals' behavior of visiting a museum. Interviews and questionnaires were conducted with visitors at the Indiana State Museum to elicit a range of their behavioral, normative, and perceived behavioral control beliefs with respect to visiting the museum and to determine the strength and importance of the salient beliefs. The findings suggest a consideration of the positive outcomes of visiting the museum—such as learning and socialization, and family members' norm in the design of a persuasive communication intervention. 相似文献

The purpose of this paper is to demonstrate the powerful and flexible applicability of the Gram–Charlier expansion to pricing of a wide variety of interest rate related products involving interest rate risk and credit risk. In this paper, we develop easily implemented approximations of the prices of several derivatives; swaptions, CMS, CMS options, and vulnerable options. Associated with the default risk, a survival contingent forward measure is constructed. 相似文献

This paper shows that the degree of information asymmetry is lower for firms with more frequent news releases. The relation holds for various measures of information asymmetry such as the probability of information-based trading (PIN), permanent price impact, and adverse selection component of bid-ask spread, even after adjusting for endogeneity between news release and information asymmetry. By decomposing the PIN into intensities of uninformed and informed trades, similarly to Brown and Hillegeist (2007), we find that intensity of uninformed trading increases much more than that of informed trading for firms with more frequent news releases. As a result, information asymmetry, as is measured by PIN, decreases for such firms due to the large increase in the intensity of uninformed trading. Our findings highlight not only the importance of news releases in leveling the playing field of investors but also the role of uninformed investors in reducing trading cost due to information asymmetry. 相似文献

Supersaturated design is a form of fractional factorial design in which the number of columns is greater than the number of experimental runs. Construction methods of supersaturated design have been mainly focused on two levels cases. Much practical experience, however, indicates that two-level may sometimes be inadequate. This paper proposed a construction method of mixed-level supersaturated designs consisting of two-level and three-level columns. The χ2 statistic is used for a measure of dependency of the design columns. The dependency properties for the newly constructed designs are derived and discussed. It is shown that these new designs have low dependencies and thus can be useful for practical uses. 相似文献

Optimal Hedging of Prediction Errors Using Prediction Errors 总被引:1,自引:1,他引:0
Yuji Yamada 《Asia-Pacific Financial Markets》2008,15(1):67-95
Wind power energy has been paid much attention recently for various reasons, and the production of electricity with wind energy
has been increasing rapidly for a few decades. One of the most difficult issues for using wind power in practice is that the
power output largely depends on the wind condition, and as a result, the future output may be volatile or uncertain. Therefore,
the prediction of power output in the future is considered important and is key to electric power generating industries making
the wind power electricity market work properly. However, the use of predictions may cause other problems due to “prediction
errors.” In this work, we will propose a new type of weather derivatives based on the prediction errors for wind speeds, and
estimate their hedge effect on wind power energy businesses. At first, we will investigate the correlation of prediction errors
between the power output and the wind speed in a Japanese wind farm, which is a collection of wind turbines that generate
electricity in the same location. Then we will develop a methodology that will optimally construct a wind derivative based
on the prediction errors using nonparametric regressions. A simultaneous optimization technique of the loss and payoff functions
for wind derivatives is demonstrated based on the empirical data. 相似文献

Privatization has been one of the significant public policies adopted in the last two decades. Previous studies have focussed on efficacy gains at the firm and industry levels. This paper intends to reconsider the distributive impacts of privatization on the economy as a whole from a theoretical perspective. Specifically, it supposes an economy with two goods, two producers and two consumers, in which it is assumed that one of the consumers is not able to obtain one good that is regarded as a necessity. Since one basis of government intervention is to provide necessity to people who would not otherwise be able to obtain it, government intervention into production is assumed to satisfy this purpose. Using comparative statics, the paper analyzes how the welfare of two consumers is affected by this intervention, and shows that intervention can increase the welfare of some consumers and social welfare in general. 相似文献

This paper estimates the economic value in the 1980s and 1990s of corporate assets in Japan, including both tangible and intangible assets, based on the neoclassical framework of McGrattan and Prescott (2005). Our estimates use a new micro-data set that comprises the accounting statements of all listed, non-financial companies in Japan. We find that in 1980–1986, a period that immediately preceded Japan?s so-called “bubble economy”, our assessed value of corporate productive assets, net of the value of corporate debt, is approximately equal to the actual stock market value of Japanese corporate equity. The finding differs from previous results based on studies of aggregate data sets or based on studies of micro-data sets that neglected intangible capital. We also show that the Japanese ratio of the amount of intangible capital stock to the amount of tangible capital stock is comparable to the analogous ratios for the U.S. and U.K. 相似文献
