We show that monopoly is the parent of monopsony when an industry employs specialized resources. This means that the welfare loss from monopoly and monopolization is larger than commonly portrayed. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

I derive a recursive formula for arithmetic Asian option prices with finite observation times in semimartingale models. The method is based on the relationship between the risk‐neutral expectation of the quadratic variation of the return process and European option prices. The computation of arithmetic Asian option prices is straightforward whenever European option prices are available. Applications with numerical results under the Black–Scholes framework and the exponential Lévy model are proposed. © 2012 Wiley Periodicals, Inc. Jrl Fut Mark 34:220–234, 2014 相似文献

The paper studies the relations between open innovation climate and job satisfaction, in particular the causal effects of the various dimensions of open innovation climate on different facets of job satisfaction. We assume firms which pursuing open innovation climate will result in higher level of employee job satisfaction. Both open innovation climate and job satisfaction are assumed to be multidimensional constructs (second-order model). Meanwhile the difference caused by employees’ organizational level was also investigated. A partial least squares path model was developed, in which significant effects were discovered. This study provides valuable materials for hoteliers who want to promote open innovation climate in their organizations. 相似文献

Available evidence shows that consumers overinsure against modest risks. For instance, a majority of consumers tend to choose too low a level of deductible for homeowners insurance and automobile insurance, and purchase excessive warranties for electronics and other durable products such as automobiles and furniture. The analysis demonstrates that overinsurance decreases consumer welfare and increases insurers’ profits. This tendency of overinsurance stems from lack of information about the probability and magnitude of loss, and it calls for policies that require insurers or third-party organizations to provide more, albeit not perfect, information and data for consumers before they make insurance-purchase decisions. The implications of the analysis for other financial products such as stocks and deposits are discussed. 相似文献

This paper aims to evaluate the effects of various forms of public research and development (R&D) support on firms’ incentives to invest in R&D. First, in order to identify potential channels through which public R&D support influences firm R&D, a formal model of firm R&D with public R&D support is developed and analyzed. Four potential channels are identified: the technological-competence-enhancing effect, the demand-creating effect, the R&D-cost-reducing effect and the (project) overlap (or duplication) effect. These multiple channels indicate that it is difficult to evaluate the aggregate effect of public R&D support and that there are differential effects of public R&D support on firm R&D, depending on various firm- or industry-specific characteristics. Second, the differential effects of public R&D support are empirically tested using unique firm-level data for nine industries across six countries. Public support tends to have a complementarity effect on private R&D for firms with low technological competence, for firms in industries with high technological opportunities and for firms facing intense market competition. In contrast, firms with high technological competence and firms that have enjoyed fast demand growth in recent years show a crowding-out effect, and firm size and age do not show any discernible differential effect. 相似文献

This study examines health inspection data from casual dining restaurants and compares differences of food code violations between ethnic and nonethnic restaurants. A total of 7,415 violations were retrieved from the restaurant inspection reports of 769 restaurants. Ethnic restaurants have more violations than nonethnic restaurant in categories related to food time/temperature violations, cross contamination, and food condition/surface/labels. Nonethnic and chain restaurants had fewer behavioral violations than ethnic and independently operated restaurants. Ethnic restaurants were 1.74 times more likely than nonethnic restaurants to have critical violations. Meanwhile, independent restaurants were 1.64 times more likely than chain restaurants to have critical violations. 相似文献

The purpose of the current study was to segment U.S. consumers into four distinct clusters based on their beliefs and motives regarding pro-environmental consumer behavior. Using a nationally representative sample of U.S. adults from Experian Simmons (N = 22,348), this study revealed that: (a) there are four clusters of consumers in the United States with a unique set of beliefs and motives regarding consumer environmentalism; (b) the clusters have distinct demographic and media usage profiles; and (c) the groups have varying responses to the industry's initiatives to protect the environment. Implications of the research are discussed in light of developing message and media strategies for green marketing. 相似文献

This study developed a procedure to determine the quality priorities of the internet protocol television (IPTV) service. First, a set of key elements of IPTV service quality was developed based on a literature review and a focus group interview. Second, analytic hierarchy process and the Kano model were applied to identify the requirements of experts and customers, respectively. The experts measured the importance and difficulty of management, whereas the customers measured the satisfaction level and importance of each quality element. Third, quality priorities were calculated through the entropy principle and scenario-based analysis. The proposed procedure is illustrated with a case study of a telecommunications company in Korea. 相似文献
