工资性收入不平等：基于户籍歧视的分析

文章利用2012年中国城镇居民与流动人口收入调查数据,采用不同的工资分解方法,从地区分割、职业分割和收入阶层的角度测算并分析了户籍工资差异及户籍歧视情况。实证结果表明,户籍歧视在不同经济发展区域都存在;户籍歧视的加剧体现在工资歧视和就业歧视两方面;对于极低工资、低工资和较高工资的劳动者而言,户籍歧视带来的收入不平等问题相当严重。     

Does Age Exacerbate the Gender-Wage Gap? New Method and Evidence From Germany, 1984–2014

ABSTRACT

Given theoretical premises, the gender-wage gap adjusted for individual characteristics is likely to vary according to age. This study adapts John DiNardo, Nicole M. Fortin, and Thomas Lemieux's (1996) semi-parametric technique to disentangle year, cohort, and age effects in adjusted gender-wage gaps. The study relies on a long panel of data from the German Socio-Economic Panel (SOEP) covering 1984–2015. The results indicate that, in Germany, the gender-wage gap increases over a birth cohort's lifetime, including in the post-reproductive age for some birth cohorts. The results suggest that age and gender are overlapping handicaps in the labor market and call for a policy intervention.     

基于交易费用理论的企业边界纵向一体化研究

交易费用理论认为，企业的最优边界在市场费用等于企业协调成本那一点，交易费用中的企业规模实质上是企业的纵向规模即纵向边界，企业纵向规模的扩张主要通过纵向一体化来实现。虽然纵向一体化能够有效地削弱人的机会主义和有限理性，克服不确定性，降低交易成本，但它并不必然是企业发展的一种好办法，企业发展到一定阶段，纵向分拆策略是有效的。企业的纵向边界呈现扩张与收缩交互进行的局面。     

Information and Communication Technology (ICT) and Singapore’s economic growth

Singapore’s remarkable success in economic development has been strongly associated with the country’s vigorous efforts to embrace the Information and Communication Technology (ICT) revolution to promote economic growth. This study provides a comprehensive investigation of the contributions of ICT to Singapore’s economic growth during the 1990–2008 period. It documents three key findings. First, there is a strong positive association between the intensity of ICT use and value-added and labor productivity growth at the sector level. Second, ICT investment contributed approximately 1 percentage point to Singapore’s GDP during 1990–2008, and its role in driving economic growth has become increasingly important over time. Third, the contribution of the ICT manufacturing sector to Singapore’s growth was notable, but it was on the decline and faced difficult restructuring challenges. This paper also provides valuable policy lessons and strategic insights for governments in both developed and developing countries that aspire to embrace ICT to promote economic growth.     

上海A股市场股票实际收益率与通货膨胀率关系的实证研究

利用VAR模型对上海A股市场2000年1月至2008年12 Yl的月度数据进行脉冲响应分析和方差分解.实证结果表明,上海A股市场股票实际收益率与通货膨胀率之间存在正相关关系.股票实际收益率对通货膨胀率的短期偏离能够在大约半年内得到修正,两者价格走势趋于一致,未来可以通过构建相关股票指数,发挥股票市场抵御通货膨胀的保值作用.     

我国经济外部失衡的SVAR分析

通过构建一个SVAR模型并进行冲击分解,探讨了影响我国经济外部失衡的两个核心变量——经常账户和人民币汇率波动的结构性冲击及其传导机制。在进行冲击分解时,不仅考虑了宏观政策的冲击,也从微观上考虑了消费者的偏好冲击。最后得出的结论是,消费者的偏好冲击能够很好地解释我国经常账户的波动,货币冲击能够对人民币名义有效汇率的波动提供合理的解释,而风险溢价冲击能够解释这两个变量之间的相互关系。     

The Urban–Rural Gap of Chinese Household Finance

Using data from a large household survey, we investigate the size of China’s urban–rural gap in ownership of bank deposits, risky financial assets, and credit cards. We further examine the factors underlying the gap using decomposition analysis. Compared to their urban counterparts, rural Chinese are much less likely to own a variety of financial products. Both demand-side barriers and supply-side barriers to financial inclusion exist in China. More, we use instrumental variable analysis to address the endogeneity of the local supply of financial service. Above all, our study indicates that a large financial services vacuum in rural areas needs to be filled.
