Teaching the Minimum Wage in Econ 101 in Light of the New Economics of the Minimum Wage

The author argues that the recent controversy over the effect of the minimum wage on employment offers an opportunity for teaching introductory economics. Research findings on the minimum wage could be used to motivate alternative models of the labor market, such as monopsony and search models, and to teach students how economists test hypotheses with data.     

Understanding Equity in the Recreation User Fee Context

Equity is a major public concern related to recreation fees on public lands. The purpose of this study was to test a three-dimensional model of equity and to examine the perceptions of equity across demographic segments. Data were collected by a telephone survey with residents (N = 366) of two western states. Confirmatory factor analysis supported the three-dimensional equity model in a recreation fee context. People tended to support democratic equity more than compensatory equity. Greater support was shown for discounted fees for the elderly and persons with disabilities than for discounts for ethnic minorities, low income people, or large families, suggesting the possibility of two sub-dimensions of the compensatory equity construct. Overall, the results do not support that disadvantaged groups seek discounted fees.     

A Response to 'Ecotourism on Trial: The Case of Billfish Angling as Ecotourism'

This paper estimates the quantity of pollutant produced by the Hong Kong hotel industry through diesel oil consumption. A survey of 20 hotels was carried out to collect three years' energy consumption data. Regression analysis indicated that gross floor area was a major and statistically accepted factor in explaining diesel oil consumption. Diesel oil consumption had reduced from the early 1990s and stabilised by the late 1990s. The sulphur dioxide, nitrogen dioxide, carbon dioxide and particulate pollution created by the hotel industry's diesel oil usage from 1990 to 1999 is estimated. The findings indicate that existing green measures and devices are passive and depend on the assimilation of the atmosphere. Environmental costs have stabilised at about HK$54,000 per annum. More proactive approaches to reduce usage and environmental impacts are proposed.     

Imparting negative news to salespeople

Sales managers often are required to give negative information to their sales personnel. Perhaps the salespeople's territories will be reduced, their compensation or expense program decreased, or their positions realigned or eliminated. Although extensive research has examined delivering negative news to sales personnel, no empirical work has yet explored how that inimical information should be disseminated to sales subordinates. Scholars in organizational psychology argue that providing adverse news to employees using interpersonal sensitivity is advantageous for both the individual and the organization. To date, though, this issue has not been investigated in a selling context. Therefore, this article reports the results of an exploratory study that investigated factors that influence whether sales managers provide negative communication to salespeople in an interpersonally sensitive fashion. © 2011 Wiley Periodicals, Inc.     

Public service and private gain

The Department of Education &; Science recently published details of the type of financial delegation schemes which schools will have to submit by September 1989. Together with other elements in the Education Reform Act, it is clear that delegation will give considerable scope to headteachers with the requisite abilities and attitudes to develop as general managers, and so create distinctive institutions which reflect their vision of what constitutes a good school.     

When leisure turns to fear: fear,mobility, and ethno-sectarianism in Belfast

There has been a considerable amount of academic discussion of the type of constraints that influence the non-use of leisure facilities. These analyses have taken into consideration such factors as gender, social class, age and mobility. At least some of these include the fear of entering certain spaces as an additional constraint. This paper reveals that in Belfast, fear, which may be based either on personal experience or on imaginary scenarios that result from rumour and innuendo, is a major factor that deters people from using accessible leisure facilities. The paper contains extensive qualitative material that underlines this point. The authors argue that, despite an ongoing peace process, the sectarianization of place has a massive impact on the use of leisure facilities and recommend that fear should be more often taken into account when constraints on leisure participation are discussed.     

Least squares model averaging by Mallows criterion

This paper is in response to a recent paper by Hansen (2007) who proposed an optimal model average estimator with weights selected by minimizing a Mallows criterion. The main contribution of Hansen’s paper is a demonstration that the Mallows criterion is asymptotically equivalent to the squared error, so the model average estimator that minimizes the Mallows criterion also minimizes the squared error in large samples. We are concerned with two assumptions that accompany Hansen’s approach. The first is the assumption that the approximating models are strictly nested in a way that depends on the ordering of regressors. Often there is no clear basis for the ordering and the approach does not permit non-nested models which are more realistic from a practical viewpoint. Second, for the optimality result to hold the model weights are required to lie within a special discrete set. In fact, Hansen noted both difficulties and called for extensions of the proof techniques. We provide an alternative proof which shows that the result on the optimality of the Mallows criterion in fact holds for continuous model weights and under a non-nested set-up that allows any linear combination of regressors in the approximating models that make up the model average estimator. These results provide a stronger theoretical basis for the use of the Mallows criterion in model averaging by strengthening existing findings.     

Modelling the Risks Associated with the Increased Importation of Fresh Produce from Emerging Supply Sources Outside the EU to the UK

The risk of non‐indigenous plant pests entering the UK via international trade in fresh produce is increasing. The objective of this article is to identify existing and emerging supply sources for UK fresh produce importers and examine the extent to which they could provide invasion pathways. We tested the hypothesis that increased imports of fresh produce from new sources outside the European Union could increase the risks of non‐indigenous insect pests. We use a bio‐economic model approach in which the number of species arrivals is a function of the volume of imports, whereas the volume of imports itself is a function of gross domestic product, relative import prices and seasonality. The study has identified clear trends, which show import volumes of fresh produce and species detections increasing from new supply sources. If this trend continues in the future, then the UK inspection agency should expect to confront species from new suppliers in much greater numbers, given that import volumes of fresh produce are income elastic.
