对逃离“北上广”的思考

2010年伊始,随着＂国十一条＂等调控政策的正式实施,＂高烧＂不退的楼市终于开始降温。上海楼市1月成交量低迷,一手房成交面积为近6年来的倒数第二,冰冻指数堪比历年楼市最惨淡时期。但年轻人＂逃离北上广＂的暗潮却汹涌,他们与其在＂北上广＂当＂蚁族＂,不如退居二线城市发展。＂逃离北上广＂的潮流显示出：中国的未来已被房价所劫持。     

Economics of an Integrated Manurial Biogas and Protein Recovery System for Beef Cattle

Fermentation of livestock manure for the production of biogas is not economically viable given current and prospective energy prices, as long as the residue from the fermentation process is used on agricultural land as a source of crop nutrients. An alternative use of the residue is to separate out the solid fraction for use as a source of protein and minerals for livestock. This alternative was evaluated for a commercial beef feedlot in Ontario, and was found to provide attractive returns using feed replacement values for the residue solids, even when a zero value was attributed to the biogas, and when real interest rates reached 7 percent. Economies of size were also found.     

Appearance-based Sex Discrimination and Stereotyping in the Workplace: Whose Conduct Should We Regulate?

Court treatment of sex discrimination and harassment claims based on appearance and gender stereotyping has been inconsistent, particularly where the facts involve reference to sexual orientation. Ironically, court willingness to allow such claims may turn on the choice of verbal or physical conduct by, or the sex or sexual orientation of, the alleged offenders. Because plaintiffs in such situations may assert retaliation claims to increase their chances of prevailing, employers should focus less on regulating aspects of personal appearance unrelated to job performance and more on problematic reactions by co-workers. Workplace civility policies may hold promise for limiting both legal liability and practical consequences in the absence of a legislative response.

Firm routines,customer switching and market selection under duopoly

This paper explores the dynamics of market selection for an industry in which firms employ relatively simple pricing, production and investment routines and in which consumers switch between rival firms in response to price differentials but do not all do so instantaneously. The key issue is whether market processes result in the elimination of less efficient firms by their more efficient rivals. That is to say, do such processes unfailingly increase the efficiency with which available economic resources are used? In the context of duopoly, we show that the survival of the more efficient firm is not guaranteed and that, more generally, the outcome depends upon the speeds with which firms adjust prices and capacities and with which customers switch between rival firms.     

Innovative work behaviour and performance-related pay: rewarding the individual or the collective?

In order to change employee behaviour, companies frequently turn to forms of performance-related pay (PRP). At the same time, there is a clear imperative to encourage employee innovation. In this study we focus on the relation between PRP, organizational and job-level task resources and innovative work behaviour (IWB). In doing so, we distinguish between individual and collective PRP and build on insights from high-performance work systems and employee creativity literature. Using survey data of 927 employees from five Belgian industries, we find that individual PRP weakens the important positive relation of task-level job resources like learning opportunities on IWB. The combination of both individual and collective PRP, on the contrary, strengthens the positive relationship between organizational resources like upward communication and IWB.     

A Smooth Transition Logit Model of The Effects of Deregulation in the Electricity Market

This paper introduces the smooth transition logit (STL) model that is designed to detect and model situations in which there is structural change in the behaviour underlying the latent index from which the binary dependent variable is constructed. The maximum likelihood estimators of the parameters of the model are derived along with their asymptotic properties, together with a Lagrange multiplier test of the null hypothesis of linearity in the underlying latent index. The development of the STL model is motivated by the desire to assess the impact of deregulation in the Queensland electricity market and ascertain whether increased competition has resulted in significant changes in the behaviour of the spot price of electricity, specifically with respect to the occurrence of periodic abnormally high prices. The model allows the timing of any change to be endogenously determined and also market participants' behaviour to change gradually over time. The main results provide clear evidence in support of a structural change in the nature of price events, and the endogenously determined timing of the change is consistent with the process of deregulation in Queensland.

Exploring Postconsumption Guilt and Pride in the Context of Sustainability

This research explores the feelings of guilt and pride experienced by consumers after a purchase decision that involves issues of environmental and social sustainability. Through a multi‐method design, the authors examine key dimensions that influence the process of emotional appraisal, illustrate the characteristics of appraisals of guilt/pride and investigate the consequences that emotions have on future choices. In this exploratory research, when a purchase decision includes an ethical dilemma, consumers were found to express guilt or pride even when the purchase is not intentional, i.e. forced by circumstances. Moreover, the study explores how emotions experienced after decisions may have a positive influence on the future purchase of sustainable alternatives. Finally, the paper proposes a new model that describes the process of emotional appraisal and reports on a number of dimensions that were found to lead to guilt and pride. The insights presented extend knowledge of two key consumer emotions and present important implications for practitioners promoting ethical products.     

Information Frictions in Uncertain Regulatory Environments: Evidence from U.S. Commercial Banks

Information frictions between firms and regulators are typically seen as a means by which firms evade enforcement. In contrast, we argue that information frictions between firms and regulators can reduce the efficiency of firms’ compliance efforts when the interpretation of regulatory standards is uncertain. We exploit plausibly exogenous variation in distance between firms and their regulators to demonstrate this for a panel of community banks in the US. We find that banks located at greater distance from regulatory field offices face significantly higher administrative costs, at a rate of 20% of administrative costs per hour of travel time. These differences do not come with reduced compliance, are not driven by endogenous regulator choice, and are stable over time. Further, the costs borne by distant firms are negatively related to the scale of the jurisdiction in which they operate, suggesting that information spillovers between firms limit uncertainty about regulatory expectations.
