We examine the impact of natural disasters on the likelihood that a government is removed from office using panel data for 156 countries over the period 1975–2010. Employing a conditional logit model, we find that the occurrence of natural disasters, the number of natural disasters and disaster-related losses increase the chances that a government will be replaced. The magnitudes of these effects differ widely across natural disaster types, but are robust to the inclusion of economic and political variables and to model specifications. Overall, these findings are consistent across our sample of OECD and non-OECD countries. 相似文献

Variance swaps are natural instruments for investors taking directional bets on volatility and are often used for portfolio protection. The empirical observation on skewness research suggests that derivative professionals may also desire to hedge beyond volatility risk and there exists the need to hedge higher‐moment market risks, such as skewness and kurtosis risks. We study two derivative contracts – skewness swap and kurtosis swap – which trade the forward realized third and fourth cumulants. Using S&P 500 index options data from 1996 to 2005, we document the returns of these swap contracts, i.e., skewness risk premium and kurtosis risk premium. We find that the both skewness and kurtosis risk premiums are significantly negative. 相似文献

There has been considerable research over the past few decades on the process through which headquarters of multinationals from developed economies exercise control over their network of subsidiaries in foreign countries. However, little research has been conducted on multinationals from emerging economies operating in developed countries. In this article, we examine the motives for, and mechanisms by which, headquarters of Taiwanese multinationals exercise control over their subsidiaries in the UK. The article draws on data collected through 66 interviews with top managers and human resource managers from four UK based subsidiaries of Taiwanese multinationals. The study reveals that Taiwanese multinationals use both output control and behaviour control to manage their subsidiaries in the UK. 相似文献

Thanks to flourishing development of the service industry for the past few years, its GDP output value is over 73%, which accounts for 58% of the employment population. The leisure service industry, in particular grows by multiple revealing its significant importance. As there is a feature of high homogeneity and substitution in the same trade, the core issue lies on enhancement of service quality in an environment of keen competition. As a result, six sigma (6σ) is applied in this research to improve service quality and increase competitiveness of the leisure industry. First, the service quality model proposed by Parasuraman, A., V. A. Zeithaml, and L. L. Berry (PZB model for short) is utilized to design the items in the service quality questionnaire. Importance and satisfaction of each service item perceived by customers are based for the scale, whose means are further converted to indexes. Thus, a scale-based service performance evaluation matrix with indices of importance as the Y-axis and those of satisfaction as the X-axis is defined. Then, service factors of high importance and low satisfaction are located and defined for improvement in accordance with the index location of each service factor. A measurement model based on the difference between customers’ importance and satisfaction is proposed and a measurement index is defined for an objective evaluation method and procedures. Next, factors of customer dissatisfaction are analyzed and improvement methods are devised. Finally, leisure service quality is monitored by the performance control model. 相似文献
