网络慈善失范现象及其治理

在网络慈善蓬勃发展的同时，各类失范现象凸显：网络慈善求助信息真假难辨导致诈捐事件频发，善款使用透明度缺失，募捐平台存在谋利行为，网络慈善沦为非法活动的工具。其主要原因包括网络慈善平台信息甄别能力有限、公开透明机制建设不足、网络慈善平台监管不够、配套法律法规不足等。因此，规范网络慈善需要强化网络慈善信息审核、加强公开透明制度建设、强化对网络慈善平台的治理以及推进法治化治理。     

Trade, product cycles, and inequality within and between countries

Abstract.  This paper incorporates Northern product innovation and product‐cycle‐driven technology transfer into the continuum‐of‐goods Heckscher‐Ohlin model. The creation of very skill‐intensive goods induces the North to transfer production of older, less skill‐intensive goods to the South. These relocated goods are the most skill intensive by Southern standards. Hence, product cycles raise the relative demand for skilled workers and thus wage inequality within both regions. This runs contrary to the Stolper‐Samuelson theorem, but accords well with the fact that wage inequality has risen in both Northern and Southern countries. Moreover, product cycles increase income inequality between countries. JEL classification: F1

The determinants of bilateral trade

Abstract.  In this paper we present a monopolistic competition model that incorporates asymmetric trade barriers and international differences in production costs. The model implies a highly non‐linear bilateral trade equation. Estimation of this equation yields parameters for the elasticity of substitution and trade costs that are more reasonable than those found in previous studies. A simulation indicates that trade liberalization will shift trade from rich countries to poor countries and from within continental trading partners with preferential trade agreements to intercontinental trading partners.

Can Chinese Discuss Conflicts Openly? Field and Experimental Studies of Face Dynamics in China

Chinese people have been theorized to be particularly sensitive to social face and avoid direct discussion in conflict to promote interpersonal harmony. Social face has been used to explain the proclivity of East Asians to smooth over conflict. More research is needed to study social face empirically and its relationship with direct discussion and the processes by which social face has its impact. Results from a field interview study and an experiment conducted in China support theorizing that confirmation of face induces cooperative goals and open-mindedness. In contrast with common assumptions about Chinese organizations, direct discussion, compared to avoiding, strengthened relationships. Direct controversy, especially when face was confirmed, induced open-mindedness: Participants asked more questions, explored the opposing views, demonstrated more knowledge of the opposing arguments, and worked to integrate views. These results were interpreted as suggesting that Chinese people can discuss their conflicts directly and cooperatively when they are assured that their face is confirmed. Results have implications both for the general theory of cooperation and competition as well as our understanding of social face in China.

The mean-variance investment problem in a constrained financial market

This paper extends the mean-variance analysis and the two-fund separation theorem to a market with some constraints, such as, the incompleteness, prohibition of short-selling, and partial information, with stochastic interest rate, and with stochastic volatility for risky assets. By maximizing a quadratic utility of terminal wealth, we show that the efficient frontier for the problem is a straight line in the mean-standard-deviation diagram. The quadratic utility function exhibits mean-variance efficiency. Our results apply to portfolios of claims in a single period, multiperiod, and continuous time.
