商业健康保险是否促进了居民健康——基于微观数据的实证研究

党的十九大报告明确提出全面实施"健康中国"战略,强调商业健康保险参与多层次医疗保障体系建设,服务广大人民群众健康保障的重要作用。明确商业健康保险如何从微观层面提高居民健康是有效发挥其助力"健康中国"作用的前提与基础。本文基于中国健康和营养调查(CHNS)2000～2015年面板数据,利用面板工具变量法解决内生性,考察商业健康保险对居民健康水平的影响,同时对不同收入阶层和年龄阶段进行异质性分析,并进行机制探讨。研究表明,商业健康保险能够显著提高居民的健康水平,而且这一正向影响对高收入阶层和中年人群的正向影响更为明显。此外,机制分析表明商业健康保险能够提高居民的医疗服务利用,改善居民健康行为,从而提高健康水平。     

Dory & Nemo Early Learning Center

The case requires students to evaluate the current situation and growth options of a small business, Dory & Nemo Early Learning Center (D&N), which provides intergenerational programming to preschool children at a retirement home. The learning center was opened in September 2014, and it was able to make a small profit each year. However, it is projected that there would be a 75 percent decrease in net income from $8,072 in Fiscal 2016 to $1,819 in Fiscal 2017. Davis and Nathans, business partners of D&N, met to discuss the following growth options: (i) Mosaic Retirement Residences' proposal to set up two learning centers at their retirement homes each year for a total of six in three years and (ii) Harmony Retirement Residences' proposal for leasing space to set up learning centers at their retirement homes, one new learning center a year for a total of three in three years. Furthermore, Davis and Nathans had decided to increase the program fee from $320 to $350 per week for the 2017–18 academic session in September. They would also like to reduce their workload from 50 to 40 hours per week, increase their vacation time from two to three weeks, and increase their salaries and bonuses. Students must consider personal objectives of business partners and mission of D&N in the analysis. They learn to identify relevant information for decision making, apply appropriate analytical tools for quantitative analysis, integrate qualitative and quantitative factors in decision making, and make recommendations consistent with analysis.     

Customers’ Risk Factor Disclosures and Suppliers’ Investment Efficiency

This study examines the effect of downstream firms’ (i.e., customers’) risk factor disclosures contained in annual reports on the investment efficiency of upstream firms (i.e., suppliers). We find that more informative disclosures of customers’ risk factors are associated with less under‐ or overinvestment by suppliers. In addition, this inverse association is stronger when the suppliers are at a bargaining disadvantage, when they operate in the durable goods industries, and when they are more concerned about the volatility of future demand. Overall, our results suggest that risk factor disclosures provided by firms in their annual reports contain useful information that could potentially help their suppliers achieve better investment efficiency.

生育政策、子女数量与中国的性别教育平等

近年来,中国性别教育差距快速缩小并呈现出女性高等教育在校生比重超越男性的现象,文章从生育政策视角对这一现象进行了解释,认为计划生育政策通过改善女性教育获得显著促进了性别教育平等。队列分析显示,生育政策之后的出生队列中女性相对教育水平明显提高,性别教育差距明显缩小。基于生育政策地区差异和出生队列差异构建的双差分模型分析发现,以农村二孩政策地区为参照组,严格的独生子女政策在提高女性相对受教育机会方面更为明显。但相对于二孩政策,一孩半政策在促进性别教育平等方面不存在显著差异,这可能由于在一孩半政策下独女户和双女户数量较少,家庭受性别偏好影响会将资源向男性倾斜,导致政策没有通过控制家庭规模提高女性相对教育获得机会。研究认为,随着中国放松生育政策,农村地区由一孩半政策过渡到二孩政策并不会对女性教育获得产生明显影响,应该关注生育政策调整对严格独生子女政策地区女性教育获得的影响。同时,随着性别教育差距逐步缩小,可以利用劳动力市场政策降低市场性别歧视,进一步提高女性地位并促进性别平等。     

China's economic development: does exchange rate and FDI nexus matter?

This study aims to investigate the relationship between China's exchange rate, foreign direct investment (FDI) inflows, and economic development. We applied the bound testing approach on aggregate level data from 1981 to 2013. The results showed that the Chinese economy benefitted from a lower exchange rate over this period, and that there was a direct link between FDI inflows and economic development on an aggregate level both in the long and short run. The results of the Granger causality test identified a long‐ and short‐run association among these variables. The GMM estimations with dummies for financial crises and RMB exchange rate policy fluctuations also confirmed the growth enhancing impact of the exchange rate and FDI inflows. To promote sustainable economic development in the future, China should focus on improving the levels of domestic investment and human capital, as well as supervising the level of openness and capital controls.     

The trend of the Gini coefficient of China (1978–2010)

ABSTRACT

This study proposes a new approach to analyse the effects of an overlap term on the calculation of the overall Gini coefficient and estimates China’s Gini ratios since the adoption of the economic reform and open-door policies. A decomposition of the Chinese Gini coefficient for 1978–2010 reveals that the key factor contributing to income inequalities is the income disparity between rural and urban inhabitants. We further investigate the features of this income inequality between rural and urban areas and employ statistical approaches to evaluate the effects of urbanisation and rural-to-urban average income on nationwide income inequality. The results show that accelerating the pace of urbanisation is mainly responsible for decreasing China’s income disparity. Drawing on these results, we conclude with suggestions for related policies.     

Growth Enhancement Support Scheme (GESS) and Farmers’ Fertilizer Use in Rural Nigeria

Fertilizer use in Nigeria is estimated at 13 kg/ha, which is far below the 200 kg/ha recommended by the Food and Agricultural Organization (FAO). The objective of this investigation was to identify the determinant factors of farmers’ participation in Nigeria's Growth Enhancement Support Scheme (GESS). In addition, we determined the impact of the GESS on fertilizer use in rural areas. A total of 1,200 rural farmers were sampled across the six geopolitical zones of Nigeria. Results from the use of a recursive bivariate probit model indicated that GESS significantly impacted on the access and usage of fertilizer among the rural farmers; and that contact with extension agents, ownership of mobile phones, power for charging phone batteries, value output, mobile network coverage, ability to read and write were positive determinants of rural farmers’ participation in the GESS; whereas increased distance to registration and collection centers, and cultural constraints to married women reduced farmers’ tendency to participate in the GESS. The findings suggest that farmers’ participation in the GESS is a critical factor for raising fertilizer use in Nigeria. This implies that food security in sub‐Saharan Africa can be achieved by increasing the participation of rural farmers in the GESS.

Home-country government support,the belt and road initiative,and the foreign performance of Chinese state-owned subsidiaries

State-owned (SO) multinational enterprises (MNEs) from emerging economies face two contradictory effects on their foreign operations due to their linkage with their home-country governments. Although home governments provide SO MNEs with resources, the affiliation also exposes SO MNEs to the legitimacy challenges in the host countries. Given this theoretical debate, we propose that home government support may facilitate SO MNEs’ post-entry operations in the host markets. Furthermore, because the legitimacy pressures directed at SO MNEs may be contingent on the interstate relations between the host and home governments facilitated by China’s Belt and Road Initiative (BRI), the BRI cooperative relations may shift the effect of home government support. Using survey and archival data, we find that home government support has a positive impact on the foreign performance of SO subsidiaries. This effect is weaker in countries that are cooperating with the BRI than in those that are not. Moreover, institutional distance weakens the negative interactive effect between BRI cooperation and home government support on the performance of SO MNEs’ foreign subsidiaries. These findings extend the institutional perspective by highlighting an alternative source of legitimacy for MNEs with distinctive attributes and in various host conditions.
