Optimal Allocation for Comparing <Emphasis Type="Italic">k</Emphasis> Test Treatments to Positive and Negative Control with Unequal Weighting Under A-optimality and MV-optimality

Experiments in real life often involve comparisons of test treatments to more than one control. However, the controls may not always be of equal importance. In this paper we introduce weighted MV optimality criterion and present a detailed study using both weighted A and MV optimality criteria, of the problem of optimally comparing a set of test treatments to two controls (positive and a negative) that are of unequal importance to the experimenter.     

Sovereign Debt Capacity and the Distribution of Domestic Wealth: A Common Agency Model*

This paper proposes a stylized two‐period, two‐country model illustrating the role of distribution of domestic wealth in determining a country's level of access to international lending. We model sovereign debt redemption policy in a common agency framework. Within this framework, policy is the outcome of the interaction between government and local and foreign interest groups with conflicting preferences on debt repayment. Our main result is that in full lobby competition, when all interests are represented, the only equilibrium solution is repudiation and the consequent inability of government to access international capital markets. Conversely, when the ability to lobby depends on wealth, governments can access international credit up to a given maximum external debt capacity, determined by the skew in the distribution of domestic wealth.     

IS CORPORATISM FEASIBLE?

This paper investigates the effects of cooperation (corporatism) on macroeconomic performance by considering a rather standard policy game between the government and a monopoly union. We stress the shortcomings of the traditional way used to model cooperation in policy games (the maximization of the weighted sum of players’ preferences), which only approximates the Nash product solution. We find that it is difficult to implement corporatism, although it generally increases social welfare, as it often reduces the union's utility. In particular, we show that an inflation‐neutral union will never find it profitable to cooperate with the government, unless side‐payments are considered. The study of this issue, however, is beyond the scope of this paper.     

Business Ethics: Law As A Determinant of Business Conduct

The Principles of Corporate Governance require that business conduct conform to the law. In recent years, news reports of business misconduct have cast doubt on a conclusion that conformity is the prevalent practice. This article explores the influence of law on business conduct by comparing the law’s requirements and purposes with actual business conduct in the market. Specifically, it explores whether certain legal regimes are more effective than others in inducing greater commitment to legal compliance by corporate actors. The conclusion drawn is that the prevalent legal regime – a vague common law or legislative mandate – is typically associated with corporate conduct that evades or ignores the law’s mandate or its underlying purpose.

箱体设备隔热降温措施研究

文章设计了一种可自然降低箱内温度的新型户外箱体结构,该箱体结构由内壁导热层、外壁隔热层以及由内壁和外壁形成的中间散热层组成。这种箱体结构可有效阻挡外界阳光和热空气的热量导入箱内,同时可将箱体内产生的热量通过内壁导热层由中间散热层及时排出箱体外。与普通金属箱体相比,箱内温度可降低10℃左右,因此,特别适合于在电力系统内的户外箱体上使用。

Understanding the cultural consumption of a new wave of immigrants: the case of the South Korean community in South West London

The purpose of the study was to develop and test a model explaining the cultural consumption of a new immigrant ethnic group (South Korean) in terms of their highbrow, middlebrow, lowbrow, public/private and ethnic minority cultural pursuits. A core premise of the study was that due to the overall higher socio‐economic standing of the South Korean community (in comparison to many other ethnic minority groups residing in the UK), this particular immigrant group would more closely resemble the omnivore and not the univore cultural consumer. A model was developed on the basis of previous literature in the fields of audience development research, arts marketing and educational sociology and was tested, consequent to qualitative interviews conducted with relevant experts and with South Korean immigrants, on a sample of 351 residents of an area in South West London that contains a high density of South Korean immigrants. The findings indicated that bridging social capital, perceived barriers to the arts, passion for the arts and educational motivation were the strongest predictors of omnivorous consumption amongst this group.

Hooliganism and Demand for Football in Italy: Attendance and Counterviolence Policy Evaluation

This paper empirically investigates the relationship between stadium attendance, hooliganism and counter‐violence policy measures in Italian Serie A. In particular, this paper analyses the impact of counter‐hooliganism policies adopted in 2007 on the quantity of game tickets sold. The counter‐hooliganism measures, grounded on an entry card, namely a ‘fidelity card’, were designed to keep out hooligans from stadiums so favouring the attendance of either occasional spectators or uncommitted fans. According to our econometric investigation the expected substitution between committed fans and uncommitted fans did not take shape. In sum, the ‘fidelity card’ did not turn to be successful if evaluated on the average attendance perspective.
