Spatial determinants of Japanese FDI in China   总被引:4,自引:0,他引:4  
Research on foreign direct investment in China has spawned an increasingly large literature. Whilst regional cleavages with respect to the distribution of foreign direct investment (FDI) are acknowledged, empirical research on the spatial determinants of FDI in China has been limited. Furthermore, research on the spatial determinants of home country FDI in China has thus far been neglected due to difficulties in accessing the appropriate data. The objective of this paper is to examine the spatial determinants of Japanese direct investment in China by using an econometric model. To that purpose, a dataset is created from the Toyo Keizai directory on the overseas activities of Japanese companies. The results show that tertiary education, inland waterways, as well as coastal location are positive and significant determinants of Japanese investment in China.  相似文献

Endogenous Group Formation   总被引:1,自引:0,他引:1  
While the rules governing the formation of groups engaging in collective action may have significant impact on group size and behavior of members, most experiments on public goods have been conducted with the subjects in exogenously fixed groups or of fixed sizes. We study endogenous formation of groups in a public‐goods provision game by allowing subjects to change groups under three sets of rules: free entry/exit, restricted entry with free exit, and free entry with restricted exit. We find that the rules governing entry and exit do have a significant impact on individual behavior and group‐level outcomes.  相似文献

We analyze a sample of 72 IPO firms that went public between 1992 and 1996 for which we have detailed proprietary information about the amount and cost of D&O liability insurance. If managers of IPO firms are exploiting superior inside information, we hypothesize that the amount of insurance coverage chosen will be related to the post-offering performance of the issuing firm's shares. Consistent with the hypothesis, we find a significant negative relation between the three-year post-IPO stock price performance and the insurance coverage purchased in conjunction with the IPO. One plausible interpretation is that, like insider securities transactions, D&O insurance decisions reveal opportunistic behavior by managers. This provides some motivation to argue that disclosure of the details of D&O insurance decisions, as is required in some other countries, is valuable.  相似文献

The objective of this paper is to analyse how much the traditions of history research (HR) and futures research (FR) have in common and how they could assist each other. First, the role of time is analysed. Second, the path dependence theory, strategic decision-making, knowledge management and visionary management are discussed. Examples of the application of the latter in water and sanitation services and their long-term development are shown. Finally, some argumented views are presented on how the convergence between FR and HR could be improved.The key point of this research is the seeming discontinuity between presents, recent pasts and near futures. The traditions of HR probably make it more difficult to assess the effects of strategic decisions on the recent. If more convergence is wanted, the gap should be filled somehow. On the other hand, the core of FR research seems to concentrate more on strategic and visionary horizons while perhaps neglecting the operational horizon of the near future.  相似文献

Abstract:  This study finds evidence of significant long-term underperformance following rights issues made during 1986-95 in the UK. The findings are resilient to a number of methodological controls. In contrast, our results for a smaller sample of open offers made during 1991-95 show strong positive performance over a 5-year post-issue period, implying that firms making open offers had better growth prospects than firms making rights issues. During 1986-90, a period when open offers were rarely used, firms appeared to be making rights issues to exploit overvaluation. However, this was not evident for rights issues made during 1991-95, a period when open offers were more commonly used.  相似文献

We extend the concept of piecewise linear histogram introduced recently by Beirlant, Berlinet and Györfi. The disadvantage of that histogram is that in many models it takes on negative values with probability close to 1. We show that for a wide set of models, the extended class of estimates contains a bona fide density with probability tending to 1 as the sample size n increases to infinity. The mean integrated absolute error in the extended class of estimators decreases with the same rate n–2/5 as in the original narrower class.  相似文献

On April 1, 1988, New Zealand stopped the double taxation of dividends by implementing a full dividend imputation program. Because many believed that the tax advantage of debt had led to more highly leveraged firms subject to greater financial risk than was socially optimal, it was hoped the removal of incentives to finance with debt would result in a more efficient allocation of capital. The empirical results suggest that the shareholder wealth gain from dividend imputation was more than offset in firms with large debt levels. Moreover, an examination of debt ratios indicates debt levels declined in the post–imputation period.  相似文献

Traditional methods of estimating market volatility use daily return observations from a stock index to calculate monthly variance. We break with tradition and estimate stock market volatility using the daily, cross-sectional standard deviation of returns for all firms trading on the New York Stock Exchange and the American Stock Exchange. We find a significantly positive relation between risk and return. Market volatility is estimated to be about half the volatility level previously reported. The intraday, cross-sectional market volatility measure provides findings consistent with risk-return theory.  相似文献
