This study presents analysis of the impact of “official product” sports sponsorships with the National Football League (NFL), Major League Baseball (MLB), the National Hockey League (NHL), the National Basketball Association (NBA), and the Professional Golfers Association (PGA) on the stock prices of sponsoring firms. The primary finding of the study is that, in the main, announcements were accompanied by increases in shareholder wealth. The 53 sponsors analyzed experienced mean increases in stock valuations of about $257 million. A multiple regression analysis of firm-specific stock price changes and selected corporate and sponsorship attributes indicates that official product sponsorships with the NBA, NHL, and PGA and those with smaller market shares were associated with the largest gains in share prices. Although corporate cashflow (a proxy for agency conflicts) is statistically unrelated to shareholder approval, sponsorships by high-technology companies were associated with stronger stock price reactions than otherwise. Finally, product congruence with the sponsored sport was positively related to changes in stock prices. T.

A pay-as-offered or discriminatory price auction (DPA) has been proposed to solve the problem of inflated and volatile wholesale electricity prices. Using the experimental method we compare the DPA with a uniform price auction (UPA), strictly controlling for unilateral market power. We find that a DPA indeed substantially reduces price volatility. However, in a no market power design, prices in a DPA converge to the high prices of a uniform price auction with structural market power. That is, the DPA in a no market power environment is as anti-competitive as a UPA with structurally introduced market power.  相似文献

Overfishing and excess capacity in mostfisheries around the world have generated considerableand increasing concern about their biological and economic performance ramifications. Theseproblems, in part, stem from substantialinvestment in technical improvements to boats andequipment in fishing fleets, which exacerbatesexcess fishing capacity and low returns tofishing effort and investment, given regulatoryand biological constraints. However, little attempt hasbeen made to quantify the extent or effects oftechnical change in fisheries. In this paper, we usedetailed data on innovation patterns for 19vessels in the Sète trawl fleet of southernFrance to evaluate the contributions oftechnical change to catch rates. We find thatembodied technical change enhanced productivity by approximately one percent per year between 1985 and 1999, but that external (disembodied) events counteractedthis trend, causing a net output decline ofabout three percent per year.  相似文献

abstract    Our study contributes towards a burgeoning literature that argues organizational performance is heavily influenced by what happens in the middle of the organization, rather than at the top. Examining the UK National Health Service, our study develops the work of Floyd and Wooldridge (1992 , 1994 , 1997 , 2000 ). It utilizes role theory to conceptualize changing experiences of middle managers in organizations as a role transition. Associated with this are problems of role conflict and role ambiguity ( Biddle, 1979 , 1986 ; Biddle and Thomas, 1966 ; Kahn et al., 1964 , 1966 ). Our study illustrates that there are limiting factors to a more strategic role for middle managers associated with the professional bureaucracy context. However, role conflict and ambiguity can be mediated by a socialization process, which values incoming identity and personal characteristics ( Van Maanen and Schein, 1979 ).  相似文献

The success of any manager depends highly on the ability to seize on opportunities that will achieve the organization's goals. Hospitals are currently searching for ways to reduce costs while maintaining or enhancing the quality of services. Quality services are increasingly being defined as those that are most responsive to customer needs. It is important, as hospital management restructures materiel systems or methods of operation for reduced costs, to focus on the user departments as the customers. The consolidation of materiel management activity should not be seen as a loss of control at the user department level. Instead it can be seen as a new way of providing service with higher quality. User departments should see concrete benefits on a weekly basis, including reduced time spent on materiel management functions; increased planning of purchasing, inventory, and distribution functions; and assistance in meeting restricted supply budgets.  相似文献

This paper employs duration analysis to investigate the timing of default in the UK mortgage market. Our analysis is performed on an ex ante basis, in that our explanatory variables are available to mortgage lenders when the loan is first made. We estimate both standard Weibull distributions and generalizations of the Weibull that permit non-monotonic hazard functions. The models fit the data well, suggesting that we have captured the major sources of variation in duration. We find that ‘cash flow’ variables, such as salary and interest rate paid, play the largest role. Surprisingly, loan-to-value ratios are either insignificant or influence default times in a counter-intuitive direction.  相似文献
