This paper examines the market for illegal recreational drugs. Under the present regime of illegality, the law acts as a barrier to entry of other firms. It also restricts the information available to consumers. Both of these effects increase the market power of traders. Other negative consequences of illegality include the use of violence to enforce contracts, poor quality control and the use of illegal activities to finance the purchase of drugs.However, legalizing the trade is likely to lead to greater drug use in the long run. This follows from the addictive nature of recreational drugs. Initial use of the drugs will drastically reduce consumers' price elasticity at any given level of consumption. Firms can increase the extent of the market by using introduction strategies, reducing consumers' price elasticities. Since newly introduced consumers have no brand loyalty, introduction strategies are public goods for firms. Free rider problems will produce oligopoly and collusion. Legalization will lead oligopolistic firms to expand the market.To avoid these problems it is suggested that the recreational drugs industry should be nationalised, not legalised. 相似文献

The political arena in the USA is portrayed as a marketplace in which businesses and other groups compete to influence public policy decisions. Managers can view this political market as an opportunity to shape the rules of the game by which they operate but must realise that it is a very competitive arena. Drawing on concepts from business strategy advocacy activities like lobbying, making campaign contributions, and organising grassroots efforts are analysed in terms of opportunities for gaining competitive advantage. Results from case studies indicate that many businesses miss opportunities to build support among employees for political advocacy because few firms use bottom up approaches for political action committees or grass‐roots efforts. Suggestions for managers interested in improving the effectiveness of their business advocacy efforts are discussed. Copyright © 2001 Henry Stewart Publications 相似文献

Abstract: The examination of printing defects, or imperfections, found on printed or copied documents has been recognized as a generally accepted approach for linking questioned documents to a common source. This research paper will highlight the results from two mutually exclusive studies. The first involved the examination and characterization of printing defects found in a controlled production run of 500,000 envelopes bearing text and images. It was concluded that printing defects are random occurrences and that morphological differences can be used to identify variations within the same production batch. The second part incorporated a blind study to assess the error rate of associating randomly selected envelopes from different retail locations to a known source. The examination was based on the comparison of printing defects in the security patterns found in some envelopes. The results demonstrated that it is possible to associate envelopes to a common origin with a 0% error rate. 相似文献

This study examined the test validity of the respondent validity scales of the Ruff neurobehavioral inventory (RNBI). In a private practice sample of motor vehicle accident pain patients (n?=?54) without neurologic injury, the scores obtained for these scales were compared with and correlated with equivalent ones on the Millon clinical multi-axial inventory III (MCMI III) and the Detailed assessment of post-traumatic stress (DAPS). Results revealed that there was a consistent pattern of convergence and divergence in response styles across the three instruments. In terms of the RNBI interscale correlations, in particular, the results suggested that premorbid positive impression management and postmorbid negative impression management are related in this type of sample. These findings add to the concurrent validity of the RNBI, suggesting that the instrument provides relevant incremental information about the type of population studied. Limitations of the study and ideas for future research were discussed. 相似文献

A large proportion of perinatally HIV-infected (PHIV) children are becoming adolescents and exploring their sexuality. This
study explored the prevalence of sexual behaviors (kissing, touching, engaging in oral sex, or having vaginal/anal intercourse)
in a sample of predominantly ethnic minority youths (N = 339; 54.1% Black and 30.4% Latino; 51% female; ages 9–16) perinatally exposed to HIV (61% HIV+). Using logistic regression,
we tested the association between sexual behavior and HIV status, demographic characteristics, and peer influences regarding
sexual behavior. PHIV youth were less likely to be sexually active. Among sexually active youth, PHIV youth were more likely
to engage in touching behavior than HIV-negative youth and were less likely to engage in penetrative sex. Youths reporting
that a greater number of their peers believed that sexually active boys were “cool” or “popular” were more likely to report
sexual behavior. The association between sexual behavior and peers believing sexually active girls were “cool” or “popular”
varied by age, gender, and HIV status. Furthermore, friends’ sexual activity was associated with sexual intercourse. Prevention
programs should strengthen messages addressing peer norms regarding sexuality, as well as address specific issues related
to adolescent HIV.

We examine the ability of pre-election polls to aggregate information about voter preferences. We show that if the electorate is small and voting costs are negligible, then an equilibrium exists in which citizens report their true political preferences. If the electorate is large or voting costs are significant, however, then no such equilibrium exists because poll respondents possess incentives to influence the voting behavior of others by misreporting their true preferences. We find that when a truthful equilibrium does exist, a poll can raise expected welfare by discouraging turnout among members of the minority. 相似文献

Most of the empirical work on the optimal size of the fiscalstate has linked the level of taxation to economic growth. Inthis paper the level of government consumption expenditure thatyields the maximum physical quality of life is found, along withthose expenditures that cause equality between marginal benefitand marginal government expenditure out of GNP. Careful attentionis paid to the measurement of the physical quality of life, theweighing of the attributes in the construction of an aggregateindex of quality of life, and in the functional (parametric) formof the nonlinear equations utilized to calculate marginalbenefit. The conclusion of the paper is that governmentconsumption expenditure is considerably higher than is necessaryto maximize the physical quality of life, and that a reductionin government consumption expenditure would not lower quality oflife. 相似文献

Abstract: There has developed in Canada a well‐established literature on bureaucratic elites at the federal level. There has not, however, been a systematic study of bureaucratic elites at the provincial level. While individual scholars have studied particular provincial governments, there have been few studies that covered more than one province. This paper, which analyses a census of assistant deputy ministers and deputy ministers in every Canadian province between 1988 and 1996, considers the mobility of these top two levels of the senior public service. The findings indicate that there has only been a slight decline in the number of senior public servants as governments have downsized. The findings also show that, unlike at the federal level, there is limited mobility among these senior public servants, with roughly one‐third of them changing each year. In some provinces, mobility levels increase slightly in the year after an election. Levels of mobility and changes in the number of senior public servants also vary across provinces, but there is no pattern based on the size of the province. Finally, there are important differences in the mobility depending on the type of department. In particular, in departments where there is a core knowledge or skill, mobility levels are much lower than in departments that lack such a core. These findings throw some light on the difficulties provinces may have in solving some of their more intractable policy problems. Sommaire: Il existe au Canada une bibliographie solidement implantée concernant les elites bureaucratiques au niveau fédéral. Il n'y a pas eu, par contre, d'étude systématique concernant les élites bureaucratiques au palier provincial. Des chercheurs ont analysé un gouvemement provincial à la fois mais peu d'études ont examiné plus d'une province à la fois. Dans cet article, qui analyse un recensement de sous‐ministres adjoints et de sous‐ministres dans chaque province du Canada entre 1988 et 1996, nous examinons la mobilité des ces deux niveaux supérieurs du fonctionnariat. Face aux réductions d'effectifs gouvernementaux, le déclin du nombre de hauts fonctionnaires semble avoir été léger. On constate aussi que, à l'encontre du palier fédéral, il y a une mobilité limitée chez ces derniers, environ un tiers changeant chaque année. Dans certaines provinces, le taux de mobilité augmente légèrement l'année qui suit une élection. Les taux de mobilité et l'évolution du nombre de hauts fonctionnaires varient aussi d'une province à l'autre, mais la taille de la province ne semble pas être un facteur déterminant. Enfin, il y a des écarts de mobilité importants selon le type de ministère. Notamment, les ministères exigeant des connaissances ou des aptitudes particulières ont des taux de mobilité très inférieurs à ceux des autres. Ces constatations mettent en relief les difficultés auxquelles peuvent se heurter les provinces lorsqu'elles essaient de régler certains de leurs problèmes les plus ardus en matière de politiques. 相似文献
