Exchange rate volatility and its impact on the transaction costs of covered interest rate parity

This paper provides empirical evidence on the linkage between foreign exchange market volatility and daily 90-day covered interest rate parity (CIP) conditions of the three major exchange rates against the US dollar (US$). Markov regime shifting models were utilized to generate time series of volatility regime probabilities and these were used to explain the first and second moments of the daily deviations from and the transaction cost bands around the covered parity conditions. We find a significant positive relationship between the deviations and the regime probabilities, indicating an increasing probability of higher volatility state being associated with rising deviations (both first and second moments) from the parity condition. Similar positive relationship is found for the transaction bands. Rising (falling) probabilities of high (low) volatility regimes increased the first and second moments of the bands. Furthermore, we find a higher volatility state combined with a US$ depreciation is associated with significantly higher volatility in the daily deviations than an appreciation. Also, US$ depreciation is associated with widening transaction bands. This suggests that the level of market uncertainty was higher when the US$ was depreciating.

Does bank competition promote financial inclusion? A cross-country evidence

The idea of financial inclusion has recently been discussed as one of the key strategies to enhance economic development (World Bank 2014). We move this discussion forward by examining if bank competition is a crucial component enforcing financial inclusion, which is arguably a finance supply-side driven process. In this study, we compute the financial inclusion index built on Sarma (2008) approach to better reflect banks’ willingness and capability to provide financial services. Applying System Generalized Method of Moments to the panel of 93 countries, we find that bank competition promotes financial inclusion.     

国有企业改革:不同思路的碰撞与选择

纵观国内外关于国有企业改革方向性选择的争论,存在主张私有化、反对私有化,和强调竞争比产权更重要三种思路.联系国有企业改革与发展实际,我们认为:私有化不是万能的、国有企业并非天然的低效率应是基本共识.因此,要坚定国有企业是可以搞好的信心.我们提出坚定搞好国有企业的信心,不是指搞好所有的国有企业,在现阶段我们认为要立足于中央企业和省(市)管企业,以完善公司治理结构为目标.本文还详细阐述了现阶段我国国有企业改革方向性选择的依据.     

利他行为的经济学解释

利他行为可以分为亲缘利他、互惠利他与纯粹利他三种形式。对前两种利他行为,生物学已经给出了较为圆满的解释,而且,这种解释也是符合经济学原理的。关于纯粹利他,生物学存在着很大争论,至今没有圆满的解释。本文在“合作剩余”和“生物演化稳定策略”(ESS)的基础上,提出一个能够解释地粹利他行为的模型．并利用脑科学的最新研究成果对这一行为内在的激励机制作出了说明。     

谈"函数和变量"思想渗透教学
