Social marketing involves influencing voluntary behaviour of people towards a social end. Examples of social marketing range from campaigns to encourage healthy physical behaviour to efforts to encourage tax support for public education, overcome racism, or stimulate ‘patriotic’ behaviour. Using data from a summer 2001 telephone survey of 600 young adults, this paper investigates how recruitment campaigns may benefit from considering gender differences in importance ratings of a variety of benefits promoted by the military in the USA. Importance ratings are assessed using differences in means and variances tests. Findings identify gender specific differences that may be used to enhance recruitment campaigns.

We examine the costs and benefits of the global integrationof initial public offering (IPO) markets associated with thediffusion of U.S. underwriting methods in the 1990s. Bookbuildingis becoming increasingly popular outside the United States andtypically costs twice as much as a fixed-price offer. However,on its own, bookbuilding only leads to lower underpricing whenconducted by U.S. banks and/or targeted at U.S. investors. Formost issuers, the gains associated with lower underpricing outweighedthe additional costs associated with hiring U.S. banks or marketingin the United States. This suggests a quality/price trade-offcontrasting with the findings of Chen and Ritter, particularlysince non-U.S. issuers raising US$20 million–US$80 millionalso typically pay a 7% spread when U.S. banks and investorsare involved.  相似文献

The paper asks the question – as time series analysis moves from consideration of conditional mean values and variances to unconditional distributions, do some of the familiar concepts devised for the first two moments continue to be helpful in the more general area? Most seem to generalize fairly easy, such as the concepts of breaks, seasonality, trends and regime switching. Forecasting is more difficult, as forecasts become distributions, as do forecast errors. Persistence can be defined and also common factors by using the idea of a copula. Aggregation is more difficult but causality and controllability can be defined. The study of the time series of quantiles becomes more relevant.  相似文献

Two of the main forces driving European emigration in the late nineteenth century were real wage gaps between sending and receiving regions and demographic booms in the low‐wage sending regions. Our new estimates of net migration for the countries of sub‐Saharan Africa show that exactly the same forces driving African across‐border migration are at work today. The results suggest that rapid growth in the cohort of potential young emigrants, population pressure on the resource base, and slow economic growth are likely to intensify the pressure for migration out of Africa and into high‐wage OECD countries over the next two decades.  相似文献

above the certainty level while for additive uncertainty the price should be lower than the certainty level. This note gives an intuitive explanation for the result after first presenting a parsimonious review of the two models. We also discuss which, if either, of the two models is more realistic. Received December 14, 2001; revised version received July 16, 2002 Published online: April 30, 2003 We thank referees for helpful comments.

We examine voting by a board designed to mitigate conflicts of interest between privately informed insiders and owners. Our model demonstrates that, as argued by researchers and the business press, boards with a majority of trustworthy but uninformed “watchdogs” can implement institutionally preferred policies. Our laboratory experiments strongly support this conclusion. Our model also highlights the necessity of penalties on insiders when there is dissension among board members. However, penalties for dissent appeared to have little impact on the experimental outcomes.  相似文献

This paper employs a latent variable approach to isolate the effects of changing tastes on the share of total meat expenditure on different categories of meat products in Greece during the period 1965–1995. We find that changes in the relative expenditure on different categories of meat cannot be explained by changes in the relative prices of the different meat products and increased expenditure alone. For pork products in particular, the increase in the share of expenditure has been greater than would be expected as a result of the relative fall in their price. The increase can therefore be associated with changes in taste. This finding is of general interest to those conducting empirical research into consumer behaviour both in economies where there have been significant changes in patterns of food consumption, and where, as in the case of many less industrialised economies, rapid structural changes in food consumption patterns are still to come. It is also of importance to policy makers in assessing die effectiveness of advertising or promotional campaigns in influencing longer term changes in consumer preferences for different products.  相似文献

Transition from a planned command economy to a market economy means tearing down a socio-economic setting where everybody follows orders and nobody bears individual responsibility for anything. The absence of personal responsibility does not promote ethical behavior in any walk of life. Today, the malnourished business ethics in the former Soviet Union creates a critical obstacle to economic development. The paucity of new official rules governing the conduct of business makes the transition process painful and difficult to people habituated to numberless rules and regulations. The first part of this paper surveys the most visible unethical business practices that have been reported by the Western media and those that are causing the largest number of complaints by the local governments and businessmen. The second part of the paper looks at ethical problems that have been under-reported.  相似文献
