人民币对美元实际汇率与中美贸易净出口关系的实证研究

中美双方的统计结果均表明,中美双边的贸易顺差是巨大的。按照中方提供的数据,格兰杰因果检验结果是人民币对美元实际汇率的变化对中美贸易净出口的变化没有统计上的影响;而按照美方提供的数据,人民币对美元实际汇率的变化对中美贸易净出口的变化有统计上的影响。然而,由于美方的数据夸大了中美之间实际上的净出口,因此美国的结论是不成立的。要解决中美之间的贸易冲突,在人民币汇率上做文章是行不通的,只有找出引起中美贸易净出口扩大的真正原因,才能有效解决中美巨额贸易顺差的问题。     

生态旅游利益相关者安全认知研究

近几年,生态旅游增长较快,己成为当今旅游业发展的热点。生态旅游迅速发展的同时,也出现了许多安全问题,如生态旅游景区游客安全事故时有发生,许多景区的附近居民与景区矛盾不断等。为了更好的促进生态旅游健康发展,选题基于利益相关者理论,选择桂林漓江古东景区作为实证研究区域,从游客、景区从业人员和社区居民三个层面对生态旅游安全认知进行了研究。     

Rating of Network-Integrated Corporations

While conventional rating systems are still focused on individual companies, in reality stand-alone business of a single enterprise respectively debtor is more likely the exception than the rule. Joint business activities of two or more companies (organizational networks) are becoming ubiquitous and have a critical influence on each partners’ success. In order to avoid that rating that turns into some rather useless ritual, network characteristics, such as network assets, network capital, network securities, network management competency, network business opportunities and network structure have to be taken into account when evaluating solvency of a network-embedded corporation. Using primary credit cooperatives as an illustrative object, this paper gives an overview on those new rating criteria becoming relevant in conjunction with network-embeddedness, so that workable opportunities can be shown to improve the reliability of ratings.      

The determinants of net interest income in the Mexican banking system: An integrated model

This paper analyzes net interest income in the Mexican banking system over the period 1993–2005. Taking as reference the seminal work by Ho and Saunders [Ho, T., Saunders, A., 1981. The determinants of banks interest margins: theory and empirical evidence. Journal of Financial and Quantitative Analysis XVI (4), 581–600] and subsequent extensions by other authors, our study models the net interest margin simultaneously including operating costs and diversification and specialization as determinants of the margin. The results referring to the Mexican case show that its high margins can be explained mainly by average operating costs and by market power. Although non-interest income has increased in recent years, its economic impact is low.

The lead-time reliability paradox and inconsistent value-of-reliability estimates

The value-of-reliability (VOR) reflects the savings in inventory-system costs from more reliable (less variable) lead times. Previous studies have revealed that more reliable, but positively skewed, lead times could actually increase optimal safety inventory when the probability of satisfying all demand during a replenishment cycle drops below 70%. Researchers claim that this paradox affects most firms and that it explains the inconsistent VOR estimates found in the transportation economics literature. Our investigation reveals that firms interested in high product availability may safely ignore the paradox and that less lead-time variability consistently increases VOR, the paradox notwithstanding.
