HMO coverage of cosmetic procedures: Response to market competition

Theory suggests that insurance policies should not cover purely cosmetic procedures. This paper attempts to explain empirical variation in coverage of a purely cosmetic procedure. Health maintenance organizations (HMOs) are modeled in a Cournot competition with two decisions—the number of policies and the limits placed on medical care utilization. Comparative statics for an individual market suggest, first, that restrictiveness is positively associated with the number of HMOs. Second, restrictiveness is positively associated with the predisposition to demand managed care products. Third, each effect is strengthened by increasing the other parameter. Restriction of tattoo ablation, a purely cosmetic procedure, is examined empirically. The first and second predictions are supported at low levels of predisposition and numbers of HMOs, while the third prediction is not supported. The data were obtained under a grant from the Office of Technology Assessment (HMO Laser Procedure Coverage) and a University of Michigan Rackham Pre-Doctoral Fellowship (InterStudy and County Business Patterns).     

Aquatic resources and recreation behavior

While substantial effort has been undertaken to understand the consequences of industrial and agricultural uses for the environment, concern has also been expressed about its other uses, including recreation. Little is known about the relationship between recreational behavior and an environmental resource base. The present paper focuses upon participation in a specific outdoor recreation activity or activity‐cluster and dominant resource base where participation occurs. Resource bases identified were river, lake, ocean, swamp/marsh, forest/mountain, range/ farm and city/town. Emphasis is placed upon aquatic environs and participation in water‐based recreation. Water activities constituted from 14–30 percent of all outdoor activities taking place at those resource bases identified. Aquatic environments provided the resource base for 38 percent of all recreation participation events, water‐ and non‐water based, occurring during one reporting period. While participation in water‐based activities requires a water resource, the array of participation patterns reported suggests that resource bases defined as recreation places provide a wide range of opportunities for non‐resource‐dependent recreation activities. One conclusion is that resource bases cannot be distinguished by the recreation activities occurring on them. Resource bases in fact facilitate a wide range of recreation activities, some holding little direct connection with the resource base, nor are the conditions of the resource sufficient to predict behavioral outcomes.     

Management training in small and medium-sized enterprises: methodological and conceptual issues

The paper examines the impact of management training and development on the organisation and performance of small and medium-sized enterprises (SMEs), via a variety of quantitative and qualitative research techniques and including both crosssectional and longitudinal approaches to analysis. The paper demonstrates the value of management training and development in SMEs and demonstrates a series of one-off and longer lasting effects on their organization and performance. The paper also highlights the conditions under which management development projects are likely to be more successful. Finally, the paper extends the schema developed by Arthur and Hendry (1990) and Hendry et al. (1991), indicating the factors influencing training within businesses, and shows the indirect and complex links between management training and firm performance.     

Customer satisfaction measurement and management: A processual analysis

Customer satisfaction (CS) measurement has been widely advocated as central to the pursuit of market orientation, total quality management, and competitive advantage by allowing management to monitor and improve performance in the terms most significant to customers. However, relatively little analytical attention has been devoted to the processual issues implicit in the adoption of CS measurement systems by organizations. This paper presents executive workshop data and new survey evidence to support the contention that both research and managerial agenda should be extended to recognize the multi‐dimensionality of organizational process, and the implications of that characteristic for the adoption and use of CS measurement systems.     

The power of asymmetric unit root tests under threshold and consistent-threshold estimation

The asymmetric unit root tests of Enders and Granger (Journal of Business and Economic Statistics, 16, 304–11, 1998) are examined using consistent threshold estimation and the original two-step procedure. In contrast to earlier studies, the ability of the tests to jointly reject the unit root and symmetry hypotheses is examined, thus permitting a fuller analysis of the tests' properties. Whilst the threshold autoregressive test is found to have little power in either its consistent or original forms, the consistent momentum-threshold autoregressive test is found to exhibit high power against a range of plausible alternatives when using newly derived critical values.

A community-based impact assessment of the Wild Coast spatial development initiative, 1997–2004

Much of the debate around the spatial development initiatives (SDIs) in South Africa is based on economic theory. To add the community perspective, an evaluation of local economic development on the Wild Coast followed a baseline in 1997 with comparable surveys in 2000 and 2004. Apart from an increase in access to piped water and a reduction in unofficial payments for health services, there was little community evidence of development over this period. Residents reported decreasing knowledge of the SDI and there was no increase in numbers considering small business ownership. In the investment-intensive ‘anchor’ areas, as in the SDI as a whole, there was no significant increase in employment and more households received remitted incomes from migrant workers. In an SDI for small businesses in tourism and agriculture, there was a dramatic fall-off in food production. No more households had loans in 2004 than in 1997, but more were taking loans from loan sharks. Other spatial planning initiatives might learn from the Wild Coast, not least through the perspectives gained from community-based impact assessments.     

Sexual Selection and Economic Positioning

Synopsis In their recent survey of Darwinian aesthetics, Grammer et al. (2003) note the surprising lack of a connection between studies related to human beauty and the theory of sexual selection. Understanding this missing link sheds new light on recent research that indicates positional concerns Pingle & Mitchell 2002, Solnick & Hemenway 1998, are important factors in the decision-making process. Integrating the theory of sexual selection into the decision framework found in economics makes it possible to explain why individuals are potentially willing to accept less, as long as it places them in a superior position relative to others.     

The New Accountability? Devolution and Expenditure Politics in Scotland

Devolution is seen to be a means for enhancing democratic control and accountability in the British political system (Scottish Office, 1997). Proponents of such change have presented it as offering the prospect of a more consensual, transparent and inclusive form of governance, in effect a 'new politics', with less executive dominance than at Westminster. This would be delivered in part by proportional representation, by strengthening the role of the legislature, and by adopting a more consultative approach to decision-making (Scottish Constitutional Convention, 1995). This article focuses on expenditure politics in the budget and audit processes of the Scottish Parliament.
