Informal group influence among situationally/dispositionally-oriented consumers

Consumer susceptibility to reference group influence has been demonstrated for certain products and buying situations. This article reports a study designed to determine if reference group influence varies between consumers classified as situationally-oriented and dispositionally-oriented. Results indicate a considerable difference between the two groups. Independence Health Plan     

The entropies: Some roots of ambiguity

Entropy concepts have developed in four general contexts—thermodynamics, communication theory, statistical information theory and social and life sciences. These concepts have five distinct mathematical forms. Ambiguity and complexity in utilization of the concept has been heightened by this multi-faceted heritage. Effective utilization may be strengthened by a sharper articulation of entropy through combinations of literal, mathematical and graphical modes of expression. Geography and planning as user disciplines have important responsibilities in enhancing cross-disciplinary communication of this important adisciplinary concept. Implications of these arguments for the social sciences include the need for caution in drawing social analogies from the ambiguous entropy concepts of statistical mechanics; and an indication of the potential benefits of social science models based on the unambiguous entropic constructs of statistical information theory.     

Mill's ‘proof’ of Utility and the composition of causes

John Stuart Mill proposed that all policy precepts, be they in the areas of morality or prudence or aesthetics, are all subordinate to the precepts of the Art of Life. The value which he assumes in defining the Art of Life is the Principle of Utility. This principle, being normative rather than fact, can admit of no proof based solely on deductive inference. Yet Mill proposed considerations that he believed capable of rationally persuading one to accept his principle as the basic principle for the Art of Life. This paper aims to evaluate this argument. In particular, it tries to show that a crucial step, often thought to be a logical howler, is not to be so simply dismissed. It is shown that if one accepts certain theses from Mill's philosophy of science and of social science, concerning the composition of causes, then the crucial step is fully justified. It is also suggested that these theses of Mill's philosophy of science are mistaken. So Mill's proof of utility is, after all, unsound, but the reconstruction proposed shows it to be much more plausible and much more philosophically interesting than is often thought.     

The Business Cycle

A bstract . Conventional macroeconomics lacks a warranted explanation of the major business cycle, while the Austrian and geo-economic Georgist) schools have incomplete theories. A geo-Austrian synthesis, in contrast, provides a potent theory consistent with historical cycles and with explanations about the root causes. The geo-economic and Austrian schools have had little interaction in the past, despite many similarities (Yeager, 1954 and 1984). Though the theories of the schools are largely complementary, each providing content the other lacks, so far a synthesis has not been forthcoming; although some geo-economists have incorporated elements of Austrian capital theory (e.g., Gaffney, 1994).     

Reply to Gehrke

This paper responds to Christian Gehrke's comment, and argues that the main conclusion of my earlier paper is sustained—that, contrary to Sraffa, Marx did not ‘adopt’ in any sense of the word the joint product method of treating fixed capital. It agrees with Gehrke that Torrens adopted a form of the joint product method, and that Malthus seems to have followed Torrens in this regard. However, it argues that Ricardo did not adopt the joint product method, not even in the one instance cited by Sraffa. Finally, it argues briefly that Marx's ‘transformation of value’ method of treating fixed capital and depreciation is superior to Sraffa's joint product method.     

The seasonal unit root structure in New Zealand Macroeconomic variables

ADF unit root tests are generally applied to macroeconomic data prior to testing theoritical models to ensure that all relevant variables are integrated of the same order. Not only is it important to test that these variables are integrated of the same order but also that a cointegrating relationship exists; failure to do so raise the specture of false inference associated with the spurious regression problem. The seasonal nature of quarterly data adds a further proplem which has generally been overcome by seasonally adjusting the data using procedure such as the census X-11 rather than suppressing it, have attempted to determine whether the seasonal component in each variable exhibits stochastic non-stationary. This paper analysisunit roots in a seasonal setting and compares the recently developed tests for seasonal unit roots as well as the standard augmented Dickey-Fuller zerop frequency unit root tests. Of the variables tested relatively few paper to be integrated at the seasonal frequenciues and, as other studies suggest,determinstic seasonal effects are typically more important than stochastic ones.
