An N-player game can be decomposed by adding a coordinator who interacts bilaterally with each player. The coordinator proposes
profiles of strategies to the players, and his payoff is maximized when players’ optimal replies agree with his proposal.
When the feasible set of proposals is finite, a solution of an associated linear complementarity problem yields an equilibrium
of the approximate game and thus an approximate equilibrium of the original game. Computational efficiency is improved by
using vertices of a triangulation of the players’ strategy space for the coordinator’s pure strategies. Computational experience
is reported. 相似文献

We examine the role of public and private interests in the passage of major legislative bills that have governed the rail industry since 1887. Our model of voting patterns in the House and Senate introduces novel measures of industry concentration, competition, and network characteristics. We find that both the level and concentration of rail infrastructure in a state, the presence of water competition, and the level of agricultural production each have a major influence over voting patterns not only for the inception of regulation but also in the major bills that deregulated the industry in the 1970s and in 1980. 相似文献

We predict that the media reports on female CEOs as a coherent group, whereas male CEOs are treated as individuals by the media. We also suggest that the resulting investors' perceptions of group entitativity of female‐led firms may not only influence the succession event–performance relationship at the focal firm, but may also have a significant effect on the value of other female‐led companies. Results of a text analysis and an event study of appointments of female CEOs to Fortune 1000 firms provide support for these predictions. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

We examine stock trading activities in days before Chinese listed firms made public announcement to start share-structure reform. There is significant evidence that, relative to a benchmark period, institutional investors bought more event firms’ shares in the last two trading days prior to announcement. Randomization tests show significant differences in institutional trading activities between event firms and matched control firms, which suggests that some institutions had inside information. Moreover, large trades account for a significant proportion of daily stock price changes in the last 2 days. The evidence is consistent with the prediction by Holden and Subrahmanyam (1992) that, when multiple informed investors acquire the same piece of information, they will trade aggressively. We also find that over the reform period, the median share value change of event firms is 6% higher than that of control firms. Our findings have important implications for enforcement of insider trading regulations in China. 相似文献

We study the impact of mainland Chinese listings in Hong Kong on the quality and development of the Hong Kong equity market. At the macro-level, we find that the increasing presence of mainland Chinese stocks in Hong Kong increases the size, trading volume, and its link with the China and world markets but reduces the overall volatility of the Hong Kong stock market. At the firm level, the increase affects the market quality, resulting in lower turnover rate, higher Amihud illiquidity ratio, and higher spread for non-mainland Chinese firms. Furthermore, such an increase in presence causes Hong Kong stocks to move in a more synchronized way and reduces these firms investment sensitivity to stock price movement, implying deterioration in the information environment. As a whole, the increasing presence of Chinese companies in Hong Kong brings benefits to the Hong Kong market, yet not without cost. 相似文献

During the NCAA basketball tournaments from 2002 to 2005, men's games produced 27% more upsets than women's games. To test whether these unpredictable results were due to gender differences, we conduct logit analysis to explain upsets by gender and other potentially significant variables, including differences in competing teams’: (i) RPI scores, (ii) percentage of freshmen, (iii) percentage of seniors, (iv) top scorer's total points and, (v) top three scorers’ total points. These analyses suggest that gender plays a significant role in explaining predictability. 相似文献

Governments all over the world put huge amounts of money into bidding for, and then hosting, sports events like Football’s World Cup or the Olympic Games. They also give money to professional sports teams and other mega-events to encourage them to locate within a particular constituency. This article examines the statistical relationship between tourism and three Football World Cups and five Olympic Games, finding very little positive effect. Given this conclusion, the article looks at why governments continue to bid for these competitions. It presents evidence that shows that these sports contests make people happy, and argues that politicians capitalize on this feel-good factor; harnessing the hubris associated with these events for political gain. The article then contends that the best way to reduce the politics associated with bidding for mega-events is to allocate them via an auction, rather than the wasteful rent-seeking methods that are currently used. 相似文献

ABSTRACTIn this article we seek to estimate the value of a partially-developed crop technology from the perspective of the firm developing the technology. Firms need this value estimation to decide whether their technology will earn a sufficient return in the market to justify investing in it. However, determining the (ex-ante) value of the technology before it is commercialised is challenging as the technology is not yet in the market and hence the demand function has not yet been defined. An alternative valuation method is required. We use risk premiums, Monte Carlo simulation and real options analysis and we demonstrate this combination of valuation tools on wheat that is currently being developed in Australia to be drought tolerant. The results indicate that this drought tolerant wheat variety is likely to be adopted by farmers in most regions and has a pre-commercialisation value that justifies continued investment in its development. We also identified South Australia as a region in which the new variety would not be sufficiently valuable to farmers to see them adopt it and we consider possible explanations for this outcome. 相似文献

This paper tests whether poorly capitalized banks with troubled loan books are more likely to miss their bailout dividends. Privately held banks with weaker core capital ratios, more charged off loans, more allowances for loan losses, and more non-performing loans are more likely to miss their Troubled Asset Relief Program (TARP) dividends. Banks that issue non-cumulative preferred stock are also more likely to be TARP deadbeats. In addition, banks that missed a bailout dividend in the prior quarter are significantly more likely to miss the next bailout dividend. 相似文献
