The economist’s oath: a review Essay

George DeMartino’s 2011 monograph, The Economist’s Oath: On the Need for and Content of Professional Economic Ethics, provides an excellent basis for the development of a discourse on the ethics of economists. This review focuses on the way in which mainstream economists’ arguments against consideration of ethics follow from their presentation of economics as a purely technical subject, and the implication that this pretense itself is unethical. The complexity of ethical issues within a pluralist approach to economics is explored, ranging from the institutional environment within which economists practice to epistemological questions.     

Company employment policies and new technology

Here the author presents case studies from a range of industries which illustrate the connection between new technology, and company personnel and manpower policies. Findings suggest that the form and direction of new technology is more likely to be affected by the company's employment policy rather than the reverse.     

Between risk and precaution – reassessing the future of GM crops

Contemporary problems tend to be inherently ‘post‐normal’ in their intimate intermeshing of scientific and contextual concerns. Yet we struggle with this mix, constrained by analytical frameworks that admit one or other of these concerns but not both. While this segregation of material and social domains has been central to the western intellectual tradition, alternative understandings transcending these distinctions have recently been developed. This paper applies some of these insights to risk. Using Actor–Network Theory risk is conceived as a dynamic entity manifested by the relationships between material and social domains rather than as something correlating to either one or other of them. This interpretation illuminates the systemic nature of contemporary problems and the solutions they necessitate underlining, in particular, the significance of matters of scale and complexity. Applied to the risk society it advances insights concerning the pervasiveness of scientific logic and its embodiment by leading institutions, while applied to public participation and HAZOP it emphasizes the benefits of unhindered, intersubjective communication. Harnessing these insights an approach of ‘epistemic pluralism’ is proposed for ‘post‐normal’ problems in which conventional insights and methods are pragmatically combined with those of the form elaborated here.     

Involvement and opinion leadership in tourism

Nature-based tourism, science tourism, and ecotourism are some of the emerging and growing trends in special-interest tourism. This study utilized a southeastern sample of the United States who had an interest in travel and the environment. A modified Dillman total design method survey was used to collect the data. The study demonstrated that widely used concepts of marketing are applicable for nature-based tourism. Results indicate that highly involved nature-oriented travelers tend to be more receptive to information concerning the travel product or destination and spread that information willingly. Findings of this study suggest that opinion leaders take more trips and use slightly more information sources.

Consumer profiles section: Consumer profiles for conventional bed and waterbed owners in Canada

This study examines consumer profile data on waterbed and conventional bed consumers. Five hundred conventional and waterbed consumers in Canada were randomly selected from two national lists of waterbed/mattress purchasers from 1981 to the present. A 73-item questionnaire was sent by mail to all of the selected respondents. The cover letter stated the purpose of the project; to study why people bought the bed that they are presently using. One hundred and sixty-two completed, useable questionnaires were returned, yielding a response rate of 37%. Following a series of multivariate analyses, a consumer profile for the two bed users was developed. Both groups tended to be married. The conventional bed consumers had: (a) either no children or one child at home; (b) a mean age of 44; and, (c) an average income in the $30,000-$40,000 range. Waterbed consumers had: (a) a mean age of 36, (b) one child living at home; and, (c) an average income in the $20,000-$30,000 range. On the Adorno F scale, the conventional bed user was found to be more conservative and authoritarian as compared to the waterbed user. The results did not support the notion that waterbed users are abnormally sexually-oriented or “kinky”. For both groups, the price paid for the purchased bed fell in the $600 to $650 range. Implications for retailers were discussed.     

A Nonlinear Model of the Term Structure of Interest Rates

We present an economically motivated two–factor term structure model that generalizes existing stochastic mean term structure models. By allowing a certain parameter to acquire dynamical behavior we extend the two–factor model to obtain a nonlinear three–factor model that is shown, in a deterministic version, to be equivalent to the Lorenz system of differential equations. With reasonable parameter values the model exhibits chaotic behavior. It successfully emulates certain properties of interest rates including cyclical behavior on a business cycle time scale. Estimation and pricing issues are discussed. Standard PCA techniques used to estimate HJM type models are observed to be equivalent to dimensional estimates commonly applied to 'spatial data' in nonlinear systems analysis.
It is concluded that techniques commonly used in the analysis of nonlinear systems may be directly applicable to interest rate models, offering new insights in the development of these models. Tests of nonlinearity in interest rate behavior may need to focus on long cycle times.
