Entry regulation and social welfare with an integer problem

This paper elaborates on Salop (1979) who showed that the number of firms at free-entry equilibrium is excessive from the viewpoint of social welfare (excess-entry theorem). This paper considers an integer problem of the number of firms entering the market. We find that the excess-entry theorem does not hold true if the marginal production cost is increasing, while it holds true if the marginal production cost is constant. This result warns against the use of the excess-entry theorem for rationalizing entry regulation such as the notorious Japanese Large-Scaled Retail Act restricting the new entry of retailers.     

Empirical analysis of real and financial volatilities on stock excess returns: evidence from Taiwan industrial data

This paper tests the relation between stock excess returns and risk factors measured by volatility. The sources of the volatility are based on the volatility of macroeconomic factors and time-series volatility. To model the macroeconomic fundamentals, we divide the risk into real and financial volatilities pertinent to Taiwan's economic environment. By examining the data of indusry excess returns and market excess returns, we find evidence to reject the hypothesis that the stock excess returns are independent of the real and financial volatilities.     

Credit growth,current account and financial depth

Exploring the determinants and dynamics of the current account balance is one of the priorities of academic literature and policy circles. Although the effects of structural variables are deeply analysed, a lesser attention has been paid to the impact of financial variables. Drawing on standard empirical current account models and with a large sample of industrial and developing countries, we report a significant deterioration in the current account balance in case of an increase in the credit growth. Moreover, we find that this link is substantially stronger for the developing ones motivating a closer examination. Therefore, we further advance our analysis and show that credit growth causes a stronger impact on the current account balance for lower levels of financial depth. In other words, at the early stages of financial development, acceleration in the credit growth might cause a larger deterioration in the current account balance; thus, it might be suggested that monetary policy and macro-prudential measures aimed at preventing financial excess might be more effective to reduce the external imbalances at the early stages of financial deepening.     

Mean-Variance Optimal Reinsurance Arrangements

Reinsurance reduces the risk but it also reduces the potential profit. The aim of the paper is to derive optimal, from the cedent's point of view, reinsurance arrangements balancing the risk measured by variance and expected profits under various mean-variance premium principles of the reinsurer. We find that quota share, excess of loss or combinations of excess of loss with quota share are the optimal rules according to a fixed expected gain of the cedent     

基于流动性下的股市透析

自1999年开始,中国政府开始推出了一系列的管理规定,使得货币市场和资本市场开始有了一定的衔接,货币政策的传导机制逐渐影响资本市场的价格和波动性,随着经济和社会法制的发展和完善,两个市场间的相关性逐渐密切。2005年以来,我国货币市场的流动性问题广泛受到国内学者和专家的关注,目前存在的流动性过剩以及股市持续高涨,房价泡沫现象与日本危机前所出现的经济现象有极大的相似性,本文试图从定性分析的角度来说明流动性过剩现象传导机制下的中国股市和其预期。     

Acquisitions: Private versus Public

Takeovers of privately held companies represent more than 80% of all takeovers. Despite their significance, studies of such takeovers and their impact on the wealth of shareholders are rare. Using a very large, near exhaustive, sample of listed and privately held UK targets we examine the impact of such takeovers on the risk adjusted return of listed UK acquirers over the period 1981 to 2001. Acquirers earn significant positive returns during the period surrounding the bid announcement although the gains are dependent on target status, mode of payment, and the relative size of those involved. The much quoted conclusion, derived from the experiences of listed firm bidders that the shareholders of acquiring firms fail to gain from takeovers, cannot be generalised. Acquiring a privately held company is an attractive option for maximising shareholder wealth.

中央银行票据:终将消逝的政策工具
