Product placement in sport video games is an emerging area of marketing and advertising communication, but it also raises controversial ethical issues. In order to investigate these issues from a consumer perspective, this study examines the perceptions of the acceptability of product placement in sport video games (SVGs). Data were gathered from 253 sport video gamers using an online survey. The results indicate that while sport video gamers generally have favorable attitudes toward product placement in sport video games, ethically-charged products such as alcohol, cigarettes, and guns are perceived as less acceptable than other products. Individual differences among sport video gamers are found based on their related attitudes, hours of playing sport video games, and gender. Also, sport video gamers who have favorable attitudes toward product placement, in general, are more likely to intend to purchase a product or brand which may be placed in sport video games. 相似文献

One of the most widely used option‐valuation models among practitioners is the ad hoc Black‐Scholes (AHBS) model. The main contribution of this study is methodological. We carefully consider three dividend strategies (No dividend, Implied‐forward dividend, and Actual dividend) for the AHBS model to investigate their effect on pricing errors. We suggest a new dividend strategy, implied‐forward dividend, which incorporates expectational information on dividends embedded in option prices. We demonstrate that our implied‐forward dividend strategy produces more consistent estimates between in‐sample market and model option prices. More importantly our new implied‐forward dividend strategy makes more accurate out‐of‐sample forecasts for one‐day or one‐week ahead prices. Second, we document that both a “Return‐volatility” Smile and a “Return‐pricing Error” Smile exist. From these return characteristics, we make two conclusions: (1) the return dependency of implied volatility is an important explanatory variable and should be controlled to reduce the pricing error of an AHBS model, and (2) it is important for the hedging horizon to be based on return size, that is, the larger the contemporaneous return, the more frequent an option issuer must rebalance the option's hedge. © 2012 Wiley Periodicals, Inc.

Summary. This paper investigates the characteristics of the optimal posted price in the standard sequential search paradigm. Much
of the intuition gleaned from the extensive sequential search literature in which the seller adopts a reservation price does
not carry over to the posted price setting. For example, an increase in buyer valuations can lead to a reduction in the optimal
posted price. We do, however, provide sufficient conditions on the hazard rate function h which ensure that an increase in demand induces an increase in the optimal posted price. As exhibited herein, the analysis
of the posted price model depends critically upon analytical properties of h. Amongst the issues treated are the elasticity of demand, finite horizon, sale of multiple units, and competitive equilibrium.

Cook, Holly and Turner recently developed a hypothesis of a positive relationship between the durability of consumers' expenditure and the asymmetric behaviour it exhibits. Supportive evidence was found by applying Sichel's tests of business cycle asymmetry to the component series of UK consumers' expenditure, which represent goods of differing durability. In this paper the relationship is re‐examined using the original data, by implementing Stock's diagnostic tests of time deformation. The results provide further support for the durability–asymmetry hypothesis. 相似文献

In this tribute to the work of Gardiner Means, we shall argue that his influence has been on a par with that of Keynes on economists of an unorthodox persuasion. It is argued that his pioneering work in studying the modern corporation as an institution that needs to be fully understood, renders him a first-rate institutionalist. Intriguingly, it is also suggested that his interest in the microeconomic foundations of macroeconomic performance are suggestive of post-Keynesian concerns. 相似文献

The third millenium will be a defining period for the future of human rights worldwide. In the second millenium, rudimentary concepts of human rights emerged, evolved, expanded and ultimately were woven into an intricate and detailed web of rights that has been globally enunciated, but not yet universally recognized and enforced. Since World War II, developments have occurred at an escalating pace. The UN and the World Court have been established. Criminal tribunals have been created, and regional courts and regional security organizations have been installed. There is growing recognition that rulers of nations must be subject to civil and criminal jurisdiction of international law. At the close of the second millenium we are witnessing the first ever indictment of a sitting ruler for violations of international criminal law. Despite important progress, many obstacles must be overcome before the rule of law will prevail globally. 相似文献

This paper addresses the usefulness of a longitudinal data file constructed from records on employers from the Michigan Employment Security Commission. We describe the main features of the data file, which includes quarterly (and in some cases, monthly) data from the third quarter of 1978 through the first quarter of 1983, plus the fourth quarters of 1983–87. We then illustrate the uses of the data with two examples: (1) studying changes in the Michigan economy, in particular the early growth and survival of new units of different sizes; and (2) studying the behavior of wages and employment following changes in ownership.Judith Connor and Steven Heeringa are primarily responsible for Section II and the Appendix, John Jackson for Section III, and Charles Brown for Section IV. 相似文献
