社会医疗保险对家庭金融资产配置的影响机制

党的十九大报告提出，要深化社会医疗保险体制改革，不断拓宽居民财产性收入渠道。而居民家庭金融资产的增长和结构变化受收入水平、教育状况等多种因素影响，其中社会医疗保险是家庭资产配置的重要影响因素。运用理论和实证的方法分析社会医疗保险对家庭金融资产配置的影响，研究结果显示：家庭风险金融资产配置的最优社会医疗保障程度在60%左右，参保家庭持有风险金融资产的概率较未参保家庭显著高了35%，社会医疗保险保障水平的提升对家庭风险金融资产配置概率、规模和比重均有显著的正向影响。社会医疗保险对家庭金融资产配置的主要影响机制是替代效应，即随着社会医疗保险保障水平的提高，家庭将安全资产转移到风险资产，从而提高家庭参与风险金融市场的深度和收益水平。     

A supply chain coordination mechanism with suppliers’ effort performance level and fairness concern

The interest conflict is an important factor affecting the supply chain (SC) performance, so it is very important to set up a reasonable coordination mechanism to eliminate the SC conflicts. Considering the fact that suppliers' effort performance level and fairness concern behavior are important factors affecting SC performance, we can develop SC models to analyze and compare SC decisions under the centralized decision and decentralized decision, and then we design a SC coordination mechanism through cost sharing. The results show that the designed coordination mechanism can effectively solve the conflict problem of SC, mobilize SC members’ motivation and initiative without damaging their profits, and realize the long-term cooperation between the retailer and multi-suppliers. It also can achieve the Pareto improvement and the sustainable development of SC.     

A re-examination of accruals quality following restatements

Empirical research from the first years following the Sarbanes-Oxley Act (SOX) in the US suggests that firms improve accruals quality following restatements, but the materiality of restatements has declined since then. This decline may affect firms' responses to restatements, and hence we re-examine whether restatements are associated with subsequent improvements in accruals quality in a more recent sample. We compare the changes in accruals quality of firms restating between 2000 and 2014 with that of a control group. We do not find that firms improve accruals quality more than the control group following a restatement, even when we isolate the types of restatements considered to be most material. However, we do find that restatements followed by the most negative stock market reactions are associated with a relative increase in accruals quality, indicating that only restatements deemed very severe by investors lead to subsequent improvements in accruals quality. Our results suggest that firms' responses to restatements have changed concurrently with the trend of fewer and less material restatements in recent years.     

工会的“收入溢价”效应研究——基于中国流动人口动态监测数据的分析

基于中国流动人口动态监测数据（2014）,实证分析流动人口工会的“收入溢价”效应。研究发现：工会能显著提升流动人口的收入,但工会的“收入溢价”效应具有异质性,城城流动人口高于乡城流动人口、签订合同者高于未签订合同者,个体私营企业的表现要优于国有集体企业和外资企业;分位数回归结果显示,随着分位数水平的上升,流动人口工会的收入效应呈倒“U”型,对中等收入者的作用最大,其次是低收入者,对高收入者的作用最小;采用倾向得分匹配法解决自选择问题,发现我国流动人口仍存在明显的工会“收入溢价”效应。     

An additional explanation for the variable Keynesian multiplier: The role of the propensity to import

This article analyzes the concept of the Keynesian multiplier from a new perspective. Several recent studies have shown that the fiscal multiplier is endogenous to the level of economic activity, increasing during recessions and decreasing during the boom. Here, we provide some evidence, explaining this variability over the business cycle, based on the overreaction of aggregate imports. Then, we apply the concept of endogenous propensity to import, varying with capacity utilization, to a neo-Kaleckian model of growth and distribution. We perform some simple simulations showing that the Keynesian multiplier increases during a recession, which logically does not advocate a reduction in public spending when the economy is in crisis.     

Do Skill Mismatches Create a Wage Penalty? Alternative Estimates for Korea*

In this paper, we estimate the wage penalty of skill mismatches among young Korean workers using propensity score matching (PSM) and ordinary least squares (OLS) methods. OLS estimates suggest that a moderate wage penalty results from skill mismatches: 3.8 percent for men and 5.6 percent for women. In contrast, PSM estimates suggest a weakly significant wage penalty for men and women only when kernel matching (KM) is used, but not when nearest neighbor matching(NNM) or radius matching (RM) techniques are used. These results contradict the findings of previous studies and suggest that there may not be a substantial wage penalty associated with skill mismatches.     

Agricultural Technology, Crop Income, and Poverty Alleviation in Uganda

This paper evaluates the ex post impact of adopting improved groundnut varieties on crop income and poverty in rural Uganda. The study utilizes cross-sectional data of 927 households, collected in 2006, from seven districts in Uganda. Using propensity score matching methods, we find that adopting improved groundnut varieties (technology) significantly increases crop income and reduces poverty. The positive and significant impact on crop income is consistent with the perceived role of new agricultural technologies in reducing rural poverty through increased farm household income. This study supports broader investment in agriculture research to address vital development challenges. Reaching the poor with better technologies however requires policy support for improving extension efforts, access to seeds and market outlets that simulate adoption.     

Moderating effect of work–family conflict on the relationship between leader–member exchange and relative deprivation: Links to behavioral outcomes

This study intends to explore the moderator of work–family conflict on the relationship between leader–member exchange and relative deprivation, and simultaneously examine the impact of relative deprivation on employees' behavior (including effort behavior and service sabotage). Questionnaire survey was conducted in 14 international tourist hotels in Taipei. Of the returned sample, 379 questionnaires are effective. The result indicates that high quality leader–member exchange relationship has negative impact on employees' relative deprivation. Also, relative deprivation has significant impact on effort behavior, and service sabotage. Furthermore, work–family conflict is found to have moderating effect on the relationship between leader–member exchange and relative deprivation. This study fills the research gap in the hospitality literature regarding the effect of work–family conflict on the relationships among leader–member exchange, employees' relative deprivation, and work behaviors. It also sheds the light on work–family conflict literature by extending leader–member exchange theory to leader–employee relationship.     

Country Segmentation of the International Tourism Market Using Propensity to Travel and to Spend Abroad

ABSTRACT

Two new segmentation variables for the global international tourism market were operationalized. These variables were used to segment the countries of the world into nine market segments, which include heavy travelers, heavy spenders (HH); heavy travelers, medium spenders (HM); heavy travelers, light spenders (HL); medium travelers, heavy spenders (MH); medium travelers, medium spenders (MM); medium travelers, light spenders (ML); light travelers, heavy spenders (LH); light travelers, medium spenders (LM); and light travelers, light spenders (LL). The profile of these country segments were further examined using discriminant analysis. Implications of findings for targeting and promotion strategies are discussed, and directions for future research are given.     

我国消费需求变动与经济增长的实证分析

消费需求对于我国经济增长具有决定性影响，既是拉动经济增长的最大动力，又是防止经济萧条的稳定力量。近几年来政府通过扩大投资启动经济的政策效果不尽如人意的主要原因在于居民消费倾向明显下降。启动新一轮景气周期的政策重心应是提高居民消费倾向，激活消费需求。
