Some tests of analytical multiobjective decision-making methods

Many analytical methods have been developed for multiobjective decision problems. All attempt to achieve the same goal. This paper reports on tests of five decision rules and seven weighting methods applied by three different panels to determine whether or not they produce different results and to infer, where possible, the nature and origin of the differences.Different methods do produce different results. Lacking a definition of “goodness,” however, it is not clear how much these differences matter. Nevertheless, some methods have obvious problems, either in theoretical validity or in application, and they should be avoided.     

Imposing curvature restrictions on flexible functional forms

A general computational method for estimating the parameters of a flexible functional form subject to convexity, quasi-convexity, concavity, or quasi-concavity at a point, at several points, or over a region, is set forth and illustrated with an example.     

Firm and industry elasticities of substitution: The two factor case

Summary For the industry composed of single output, two factor firms, industry elasticity of demand for one of the factors with respect to the price of the other is negative or positive as the elasticity of demand for industry output is greater or less thanindustry elasticity of substitution between the factors. Using isoclines, vectors, isoquants, and isoscales, it is shown that, where firm isoquants are non-homothetic, industry elasticity of substitution for constantindustry output allows for adjustment of the level of firm output, and thus exceeds firm elasticity of substitution for constantfirm output.He wishes to thank two anonymous referees for helpful suggestions.     

Border tax adjustments: Do they distort trade?

A familiar proposition asserting the trade-neutrality of uniform, indirect taxes under both the origin and destination principles is re-examined in the context of a world with trade in intermediate goods. A uniform, general sales tax is shown to be trade-neutral under the destination principle, but trade-distorting under the origin principle. A ‘stage of processing’ value added tax is nondistorting under either border tax adjustment principle. The discussion is then related to a proposed change in GATT rules that would require origin principle administration of the European value added tax.     

Coming to Terms with Leisure and Globalization

Abstract

This article is concerned with the engagement of leisure studies as an academic field and as organized, professional intervention with the phenomenon of globalization, using the exemplificatory case of the World Leisure and Recreation Association’s (now World Leisure’s) Sao Paulo Declaration on Leisure and Globalization as a point of reference. Deploying a combination of globalization theory and ‘autoethnographic’ research in relation to instances of mediated leisure culture, it reflects on conceptual imprecision and potential contradictions in the Declaration as indicative of wider problems in the disciplinary field. Leisure studies researchers are enjoined to avoid complicity in promoting both dystopian and utopian versions of globalization theory, and sceptically to assess the complex interaction of globalizing and other macro/micro processes. The article concludes by arguing for a wide‐ranging, critically reflexive leisure studies research agenda supported by principled strategic interventions in leisure power relations.
