人民币汇率传递机制研究与启示

汇率传递是指汇率波动通过直接或间接的渠道影响国内价格,影响汇率传递的因素主要包括外贸依存度、市场竞争和市场创新等方面。我国汇率传递效应受市场不完全竞争的影响,其汇率传递效应亦不完全。可以通过企业加速产品结构调整和技术创新,适应汇率弹性增强的需要;加快产业升级与结构调整;并继续实行富有弹性的汇率制度。     

股价与中国上市公司投资——盈余管理与投资者情绪的交叉研究

本文考虑到中国证券市场代理问题及信息不对称严重和投资者非理性状况共存的特征,将盈余管理与投资者情绪结合起来分析两者对股价的影响,进而分析两者与中国上市公司投资的关系。通过划分平静时期和动荡时期,本文发现在不同的时期里,盈余管理与投资者情绪导致的错误定价关系两者趋势并不总是一致;盈余管理和投资者情绪在不同时期里分别主导着股价与公司投资的关系;而且在不同时期里,融资约束和换手率对所研究问题的影响也是不同的。

The peer effect in adverse selection: Evidence from the micro health insurance market in Pakistan

The peer effect may amplify adverse selection in social networks, hampering the sustainable operation of microinsurance. This paper uses data from a micro health insurance program in Pakistan to test for the peer effect in renewal decisions and the role it plays in amplifying adverse selection within social networks. The paper finds evidence supporting that insurance renewal decisions are similar among peers in the same network, and the peer effect is stronger among households of the same risk type than households of different risk types, indicating that the heterogeneous peer effect acts as an amplifier for adverse selection. The paper provides policy implications for effective ways to mitigate the peer effect and adverse selection, based on the results of heterogeneity analyses. The policy recommendation is to enforce a minimum group enrollment rate requirement of at least 60% for large groups to mitigate the peer effect.     

The Changing Roles of Industry and Country Effects in the Global Equity Markets

Abstract

This paper examines the roles of country and industry effects on international equity returns using a comprehensive database covering 50 industry groups and 34 countries over the period 1992 to 2001. The study focuses on the evolving process of those effects over time and on geographical differences. The main results are as follows: although the country effects still dominate the industry effects in the full sample period, there has been a major upward shift in industry effects since 1999. The degree of this shift varies across regions and is prominent in Europe and North America, while in Asia Pacific and Latin America, country effects still dominate. The increasing industry effects are not found to be confined to the Technology, Media and Telecommunications sectors and thus are not considered a temporary phenomenon. The above developments have implications for international portfolio diversification.     

Optimal proportional reinsurance to minimize the probability of drawdown under thinning-dependence structure

Abstract

In this paper, we consider the optimal proportional reinsurance problem in a risk model with the thinning-dependence structure, and the criterion is to minimize the probability that the value of the surplus process drops below some fixed proportion of its maximum value to date which is known as the probability of drawdown. The thinning dependence assumes that stochastic sources related to claim occurrence are classified into different groups, and that each group may cause a claim in each insurance class with a certain probability. By the technique of stochastic control theory and the corresponding Hamilton–Jacobi–Bellman equation, the optimal reinsurance strategy and the corresponding minimum probability of drawdown are derived not only for the expected value principle but also for the variance premium principle. Finally, some numerical examples are presented to show the impact of model parameters on the optimal results.
