INCOME REDISTRIBUTION THROUGH THE TAX SYSTEM: A SIMULATION ANALYSIS OF TAX REFORM

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.     

碳贸易价格风险变动趋势与我国CDM发展策略

本文构建并拟合了包含分布转换的Markov-GARCH模型,计算了基于该模型的风险价值(VaR),对国际碳贸易市场价格风险变动趋势进行了分析。研究结果表明:碳贸易市场价格在均值、方差、峰度、波动聚集性以及分布形式方面都具有机制转换的特性;欧盟推出的EU ETS改革措施将促使未来碳贸易市场价格波动风险进一步降低。我国应当适时提高CDM合同最低限价;减少向CDM合同国际买方支付的风险溢价;暂停上马HFC-23和N2O分解类项目;加快国内碳贸易和碳金融市场的发展,争夺国际碳贸易市场定价权。     

Structural and competitive determinants of globally oriented small- and medium-sized enterprises: An empirical analysis

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.     

Employer risk-adjustment transitions with inertial consumers: Evidence from CalPERS

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.     

The Effects of Incidence of Care Needs in Households on Employment,Subjective Health,and Life Satisfaction among Middle‐aged Family Members

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.
