Thomas Carlyle on the use of numbers in economics

Thomas Carlyle’s criticism of economics goes far beyond his epithet, “Dismal Science.” One aspect of economics that attracted his attention was its use of numbers in both theories and empiricisms. Here is explored his attacks on economist’s use of arithmetic in explaining human behavior, and statistics in addressing the condition of the working class.     

Consumer preference among fluid milks: low‐fat vs. high‐fat milk consumption in the United States

The present study uses data from the Continuing Survey of Food Intakes by Individuals 1994–1996, 1998 in order to analyse milk consumption by type, specifically high‐fat milk vs. low‐fat milk. Whereas trend analysis displays an overall increase in low‐fat milk consumption over the last few decades in the United States, a number of individuals still consume high‐fat milk varieties, and overall dietary intakes have yet to achieve recommended levels. In light of recent research regarding fat intakes, it is important to understand what factors might cause consumers to purchase high‐fat options given the number of low‐fat options available in the market. Through the use of Logistic regression, key socio‐economic and demographic variables are analysed in order to determine their impacts on the probability of consuming low‐fat milk vs. high‐fat milk. The results indicate that a number of factors do influence probability of low‐fat milk consumption as compared with high‐fat milk consumption. Most notably, probability of low‐fat milk consumption appears to be positively related to age, education level, and income level. African Americans and other minorities had a lower probability of consuming low‐fat milk when compared with White people in the sample population. Also, those respondents designated as low income or living in the South were less likely to consume low‐fat milk.     

Likelihood ratio tests for model selection of stochastic frontier models

An important issue when conducting stochastic frontier analysis is how to choose a proper parametric model, which includes choices of the functional form of the frontier function, distributions of the composite errors, and also the exogenous variables. In this paper, we extend the likelihood ratio test of Vuong, Econometrica 57(2):307–333, (1989) and Takeuchi’s, Suri-Kagaku (Math Sci) 153:12–18, (1976) model selection criterion to the stochastic frontier models. The most attractive feature of this test is that it can not only be used for testing a non-nested model, but also still be applicable even when the general model is misspecified. Finally, we also demonstrate how to apply this test to the Indian farm data used by Battese and Coelli, J Prod Anal 3:153–169, (1992), Empir Econ 20(2):325–332, (1995) and Alvarez et al., J Prod Anal 25:201–212, (2006).     

Relationship between Treasury bills and Eurodollars: Theoretical and Empirical Analyses

In this paper, we derive an equilibrium relationship between the yields on Eurodollar and Treasury bills based on equivalent martingale results derived by Harrison and Kreps (1979) and Harrison and Pliska (1981, 1983) as well as the corporate debt pricing model developed by Merton (1974). The derived equilibrium relationship incorporates the models used by Booth and Tse (1995) and Shrestha and Welch (2001) as special cases. The equilibrium relationship indicates that the conditional volatility of the yield on Eurodollars explains the variation in the TED spread. We empirically test the equilibrium relationship using a GARCH-M model and the concept of fractional cointegration. We use both the ex ante data implied by the respective futures contracts as well as the ex post spot data with daily, weekly and monthly frequencies. We find empirical support for the Equilibrium relationship.

Towards a pre-service technology teacher education resource for New Zealand

The Pre-service Technology Teacher Education Resource (PTTER) was developed as a cross-institutional resource to support the development of initial technology teacher education programmes in New Zealand. The PTTER was developed through collaboration involving representatives from each of the six New Zealand university teacher education providers, Massey University, University of Auckland, University of Canterbury, University of Otago, Victoria University and University of Waikato, working with the National Technology Professional Development Manager. The framework for PTTER is built on four key elements considered to be essential to the education of technology teachers. The four elements are: philosophy of technology, rationale for technology education, technology in the New Zealand curriculum, and teaching technology. The PTTER is a web-based resource aimed at assisting technology teacher educators in the development of their teacher education programmes. The framework is a statement of shared philosophy, purpose and intent and is located on the Techlink website (www.techlink.org.nz). PTTER contains a range of teaching resources and strategies located within an overall framework for initial technology teacher education programmes. This paper describes the rationale for the PTTER framework, the process through which it was developed, explanation of each of the framework’s elements, and concludes with discussion of the framework’s implementation and future development.     

Paradigms and Novelty in Economics: The History of Economic Thought as a Source of Enlightenment

Over time, economics has experienced paradigm shifts, and there is every reason to think this will continue. In economics, as in the development of technological knowledge, paradigms do not emerge from nowhere, but build on precursors, possibly from other fields. Our understanding of current economic thinking can be enhanced by paying greater attention to the role of paradigms and by using concepts such as myth, plot structure, and cultural endowment, which are typically given greater attention by literary analysts than by economists, to study paradigms. Here we argue that together these can help us better understand how ideas from other times and fields may be combined with our own to generate better research and publications, and that a greater awareness of the history of economics may well be an excellent vehicle for enhancing that understanding.     

International human resource management: An Australian perspective

International human resource management (IHRM) is slowly emerging as a field of academic enquiry. There is, however, a dearth of case study material which documents IHRM strategies and experiences of companies-particularly companies which do not have their home base in the United States. This paper reviews current IHRM literature and reports the results of a recent study of four companies operating internationally from Australia: two are Australian-owned; one is an Australian subsidiary of a multinational oil company and the fourth is a regional division of a multinational automobile manufacturer. For the collection of data, a case study approach was used, with structured interviews of each company's personnel director, expatriate line managers (including returned managers and foreign nationals currently in Australia) and spouses. These case studies are analysed and the extent to which they contribute to the international human resource management literature is examined.The authors would like to thank the companies which participated in the study, and Mary Anderson, Hugh Davies, and Helen De Cieri for comments on earlier versions of the paper.     

Whose Human Capital? The Challenge of Value Capture When Capital is Embedded

abstract    Current approaches that position human capital as central to value generation in knowledge-based industries obscure the importance of the relational nature of knowledge production. That is, separable and embodied forms of capital are interdependent in value creation and capture processes. We identify a relational form of capital, embedded capital, which we argue is the critical resource in knowledge-based industries such as professional services firms, because it allows us to include agency and interdependency in the value capture process. These dimensions have previously been overlooked by the resource-based view of the firm. Examples of embedded capital include brand value, processes and procedures. The deployment of embedded capital is also not clearly controlled by either the firm or individual employees. A model is developed to illustrate the links between each form of capital, and the processes of value capture. This conceptual identification of the embedded form of capital is therefore of importance to future value creation and capture debates.
