Basel-2 capital adequacy: Computing the ‘fair’ capital charge for loan commitment ‘true’ credit risk

This research makes two contributions: (i) to price analytically put option and extension premium embedded in a borrower-extendible commitment, and (ii) to compute the ‘fair’ capital charge that corresponds to the commitment ‘true’ credit risk. In doing so, the procedure replaces the BIS accounting-based concepts of credit-conversion factor, principal-risk factor, and initial term to maturity of irrevocable commitments with the market-based concepts of exercise-cum-takedown proportion and put value implicit in the borrower-extendible commitment, respectively. Finally, the approach is developed one step further to account for the borrowers' risk ratings by public credit agencies; this results in a two-dimensional (time-state of nature) risk-weighting system that applies to all commitment types.     

The trading behavior of institutions and individuals in Chinese equity markets

This paper employs a unique data set to analyze the trading behavior of 4.74 million individual and institutional investors across Mainland China. Results show that groups of individual investors with varying trade values (as proxies for wealth levels) engage in different trading strategies. Chinese institutions are momentum investors, while less wealthy Chinese individual investors at large are contrarian investors. The results also indicate that a small group of wealthiest Chinese individuals tend to behave like institutions when they buy stocks, and behave like less wealthy individuals when they sell. Furthermore, only the trading activities of institutions and of wealthiest individuals can affect future stock volatility, but those of Chinese individual investors at large have no predictive power for future stock returns.     

论我国外汇储备币种结构多元化

目前我国已经成为世界上外汇储备持有量第一大国，在国际金融市场风云突变的今天，持有的外汇储备越多，承担的外汇风险也就越大。稍有不慎，持有巨额的外汇就会面临风险，不仅不会带来收益，还可能遭受损失。各国均有很多专家对本国的外汇储备进行研究，以求其增值、保值。本文就目前我国外汇储备币种结构的现状及其存在的问题与可能面临的风险进行分析，提出外汇储备币种结构多元化是我国外汇保值、增值的根本途径这一观点。

Contingency view on technological differentiation and firm performance: evidence in an economic downturn

Although the importance of strategy for firm performance has been studied, little evidence has been offered regarding this linkage in hostile environments characterized by a lack of exploitable market opportunity and fiercer competition. This study aims to examine the viability of strategic postures of technological differentiation in such a setting using data from 1,054 samples across 32 industries in 30 countries during 2001–2002, when global economies suffered a downturn. The empirical results show that differentiation-oriented firms underperformed efficiency-oriented ones during this period. However, in the face of deteriorating market conditions, a strategic orientation toward technological differentiation, in concert with an internal commitment to R&D investment or external munificence toward technological opportunity, yields better performance. Finally, this study finds that firms with tight coupling between differentiation and efficiency outmaneuver those with a pure strategy or no strategy at the time of an economic downturn.
