The Value of Changes in Deer Season Length: An Application of the Nested Multinomial Logit Model

Increasing deer populations can be controlled through manipulatingharvest limits or season length. While such actions often result in benefitsto hunters, both motorists and the agricultural sector also benefit as alower deer population leads to fewer incidences of harmful human-deerencounters. Traditional recreation demand models are often employed toexamine the welfare implications of changes in daily hunting bag limits.Studies measuring the effects of changes in season length, however, arenoticeably absent from the literature. This study uses a nested randomutility model to examine hunter choice over site and season selection toderive the values of changes in season length.     

(某些)品德教育对自由主义民主的危害

本文以在加拿大多伦多市一大郊区开发的一个研究项目为案例,批评了北美“品德教育”的某些方面是怎样对维持一个健康的自由主义民主社会造成危害的。作为这种批评之基础的假设认为,把自由主义的动机作为一种政治理论确定下来,并且认为这种动机就表现在民主的原则和实践中,是为了解决生活在同一社会中的人们之间的(几种)冲突,而且要做到这一点,只要把公民的角色分化出来,按照这个目的进行建构即可。以此为抓手,本文把关注的焦点集中在这种观点的危险性上,认为这种观点无法区分好人和好公民这两个概念,尤其是在文化多元主义已经深入人心的背景中。     

CGE assumptions under scrutiny: uncertainty in the ethanol promotion policy in Mexico

Based on a CGE exercise of a subsidy to initiate ethanol production in Mexico, we use Monte Carlo simulations for consumer demand elasticities and ethanol cost estimates. The analysis provides three conclusions: when markets vary smoothly and predictably, Monte Carlo methods can then help to gauge the actual probability that a given program will achieve a desired outcome. Second, secondary markets may display little or no sensitivity to these parameter variations. Finally, a ‘razor’s edge’ outcome with no positive benefits if a critical parameter falls below some critical value, reveals that an economic policy may not be conducive to ‘fine tuning’ by marginal adjustments.     

Like father, like son? A note on the intergenerational transmission of IQ scores

Using a large population-based dataset, we estimate a substantial intergenerational transmission of IQ scores; a 10% increase in father's score at age 18 is associated with a 3.2% increase in son's score. This relationship also holds true for various subpopulations.     

Optimal new-product pricing in regulated industries

Intertemporal pricing issues faced by regulated monopolists in market settings characterized by high rates of innovation have received little attention in the regulatory economics literature. Most analyses of regulatory pricing have focused on monopolies characterized by a stable multiple-good product set. In a regulated industry characterized by technological change in the form of new products and services (such as telecommunications), optimal pricing decisions may also reflect intertemporal market and production factors. In this paper, two such intertemporal factors are modeled: learning curve effects on the firm's cost function, and customer demonstration effects on the demand side of the market. Inclusion of these factors leads to an intertemporal pricing rule that may conflict with the standard regulatory practice whereby each product or service must recoup its own resource costs period by period. Our results suggest that this regulatory practice can result in efficiency losses, since it results in a rate of technological diffusion that is too low.     

根深蒂固的自由主义和压迫性的社群关系--道德教育主体面临的一个两难困境

现代西方道德政治理论中,自由主义主体这个概念作为道德经验、阐释、批评的中心一直非常繁荣。然而,本文认为某种道德上意义重大的关系——那种通过分等级的权力结构由互相联系的社会群体构成的关系——构成的一种不同的主体意识需要更多的理论和实践上的注意。和自由主义的四种核心特征相对应,本文从个体是怎样成为一些特殊的社会群体的成员来论述一种主体意识视角。文章认为,除非道德教育能认识到这种主体意识,否则道德教育本身就冒着为压迫形式(如种族歧视)作贡献而不是同它搏斗的风险。     

Jointism and the Role of the Workplace Union in the auto-components Industry

This article is part of a case study history, from the British auto-components industry involving a changing workplace regime from the late 1970s through to the 1990s. Employing the concepts of 'dual commitment' and 'incorporation' we explore, partly through the voices of participants, the process of involvement in that regime. We consider the implications for how trade unions might respond to policies on 'jointism', and for management vis-a-vis the choices on union involvement or anti union strategies.     

The Union Makes Us Strong? A Study of the Dynamics of Workplace Union Leadership at Two UK Manufacturing Plants

This paper draws on qualitative case study evidence to investigate the way in which union leaders involved in two workplace organizations deal with the process of managing their role within the employment relationship. In particular, the influence of their leadership style on the commitment and participation of rank-and-file members is considered. The paper highlights the dialectical relationship between local leaders and members in terms of trade union democracy and local leadership style.
