In this paper, we consider reforming the tax system to a comprehensive income tax model in order to amend the differential treatment of income sources. Our simulation analysis shows that the tax reform improves the effectiveness of the tax system on the redistribution of all sources of income including earned income, financial wealth income, and imputed rent. The analysis of incidence of the tax reform suggests that the tax burden for young renters decreases the most and that for young loan-free land owners increases the most through this tax reform.  相似文献

This paper examines the factors influencing the internationalization of the activities of small- and medium-sized enterprises (SMEs) as an entrepreneurial response to the opportunities and threats posed by the increasing globalization of the economic system. Findings from agricultural equipment manufacturers indicate that size, international experience, innovation, and distinctiveness have a direct influence on the degree in internationalization by SMEs. Scanning, learning, and networking have some influence on the extent of internationalization of SME activities but only indirectly through other variables. Competition intensity and uncertainty also have an indirect impact on internationalization, but standardization does not. Relative importance of each determinant is ascertained and the impact of SME internationalization activities on performance is assessed.  相似文献

Risk-adjustment policies, which transfer money from insurers with healthy consumers to those with sick consumers, are an important tool to contend with adverse selection in health insurance markets. While the steady-state properties of risk-adjustment have been studied extensively, there is less evidence on the transition phase of policy implementation. We study the introduction and removal of risk-adjustment at California Public Employees' Retirement System and show that these changes meaningfully impact premiums via plan differences in enrollee health status. Despite these premium differences, there is limited consumer resorting due to consumer inertia, though new active enrollees respond more fluidly. We show that, with inertial consumers, risk-adjustment changes have substantial distributional consequences, leading to worse outcomes for sicker consumers when removed and vice-versa when implemented. We estimate a model of plan choice with premium sensitivity, brand preferences, and inertia and use these estimates to study the interaction between risk-adjustment policies and the strength of inertia.  相似文献

In this study, based on longitudinal data, we investigate whether Japanese middle‐aged men and women become less likely to have a job and whether their sense of well‐being decreases when they have a family member who needs care. We find a consistent negative impact of having a family member who needs care on employment, but no impact on subjective health and life satisfaction. Further, the differences‐in‐differences (DID) estimation, based on both unmatched and matched data, shows that the Long‐Term Care Insurance (LTCI) introduced in 2000 did not mitigate the adverse impact on the probability of being employed.  相似文献
