Public health campaigners have criticized the British system for the regulation of alcohol advertising, which relies on several distinct codes of practice governing different media. This paper looks at the options for change, in the light of the economic, political and technological factors that will influence the development of the UK's alcohol advertising policy in the 1990s. The available evidence on the costs and benefits of alternative policies is reviewed, drawing on the Addiction Research Centre's multi-disciplinary programme of work undertaken at the Universities of Hull and York. While there is some evidence that a ban on alcohol advertising would have a marginal effect on overall consumption, it is argued that legislative intervention is no longer feasible. Technological innovation and global pressures for deregulation have made it difficult for national governments to ban the advertising of any one product. At the same time, however, it is feared that commercial pressures resulting from the introduction of satellite broadcasting and the increased competition for advertising revenues could undermine the existing self-regulatory system and exert a downwards pressure on advertising standards. It is suggested that the way forward lies in developing a strong self-regulatory system throughout Europe. 相似文献

Dictator games: a meta study 总被引:2,自引:0,他引:2
Christoph Engel 《Experimental Economics》2011,14(4):583-610
Over the last 25 years, more than a hundred dictator game experiments have been published. This meta study summarises the
evidence. Exploiting the fact that most experiments had to fix parameters they did not intend to test, in multiple regression
the meta study is able to assess the effect of single manipulations, controlling for a host of alternative explanatory factors.
The resulting rich dataset also provides a testbed for comparing alternative specifications of the statistical model for analysing
dictator game data. It shows how Tobit models (assuming that dictators would even want to take money) and hurdle models (assuming
that the decision to give a positive amount is separate from the choice of amount, conditional on giving) provide additional
insights. 相似文献

Risk aversion experiments such as those by Holt and Laury (2002, 2005) measure risk aversion by examining subjects’ responses to a series of probability-ordered choices. Subjects are paid real
money rewards, using the random round payment method in which the amount is determined by one randomly selected decision.
The findings reported here were obtained from 119 subjects who confronted the same choice set and payment amounts, but 60
of these subjects were paid using the random-round method while the remaining 59 were paid based on an average of all their
choices, the accumulated value method. The accumulated value payment method simulates portfolio returns, as opposed to returns
from stand alone investments. Results indicate that accumulated value subjects took more risk and made more inconsistent decisions. 相似文献
