Joseph Schumpeter, a careful reader of Hayek, categorized Hayek??s theory of economic cycles as non-monetary. Almost every other source, including Hayek himself, categorized the theory as monetary. The issue turns on the concept of causality being used. The question of what causality concept to apply to complex phenomena has substantive implications for economic theory. A simple concept of causality, appropriate to the study of some physical phenomena, will mislead when applied to complex phenomena. We provide examples of errors in analysis that follow from the wrong choice of a causal paradigm.  相似文献

Good estimates place ‘hard core’ smoking rates in the United States at approximately 25%, with little change over the decade of the 1990s. This paper examines the possibilities of ‘harm reduction’ with the use of smokeless tobacco. Specifically, using an econometric model we seek to determine whether an increase in the use of smokeless tobacco would lead to reduced smoking rates in the United States. Applying our model to the NHANES III (National Health and Nutrition Examination Survey) we find that the use of smokeless tobacco by an average U.S. male smoker would increase the average probability of smoke cessation by over 10%. Approximately 3 million additional ‘quits’ would result for 26 million smokers. Our study permits an examination of cessation by age groups and we find that males who use smokeless tobacco between 16 and 65 have a 10–14% probability of quitting but that the probability falls beyond age 66. Important implications for life extension and health costs would attend these results with, under conservative assumptions, life years saved approximating 2.16 million and health care cost-savings of about $3 billion per year.  相似文献

The major objective of this study is to estimate Korean food shoppers’ willingness to pay (WTP) for imported beef with traceability. We use an experimental elicitation method, the random nth price auction, to identify consumers’ valuation for traceable imported beef. We also analyse the effect of different types of information on these valuations. Results indicate that consumers are generally willing to pay a 39 per cent premium for the traceable imported beef over similar beef without traceability. Results also suggest that in contrast to the insignificant effect of positive information, negative and two‐sided information about traceability significantly reduces WTP.  相似文献

Abstract

Two issues make advertising effectiveness difficult to assess: (1) advertising effects occur both during ad processing and when ad information is retrieved, and (2) the information that consumers derive from advertisements is likely to be some combination of explicit information and inferences. The study reported in this paper addresses these issues, examining the effects of encoding and time delay on advertising processing. Results indicate that while some types of inferences (product features) are more likely to be made under strong than weak encoding conditions, other types of inferences (consumption situation) are not affected by encoding. In addition, at the time of a decision (after a time delay), memory information use depends both upon individual brand accessibility and the relative accessibility of alternative brands in the memory set. Implications for both advertising researchers and managers are offered.  相似文献

Abstract

Cross-spectral analysis is recognized as a powerful analytical tool for the analysis of time-varying behavior in a number of disciplines. Applications in business have been limited, however, and the potential usefulness of this new approach to time series analysis has received relatively little attention in advertising. The purpose of this paper is to explain cross-spectral analysis and illustrate the use of this new technique in studying the interaction between advertising and sales.  相似文献

This note shows that the impact of an increase in product price on factor demand in the typical textbook depiction is overstated to the point of indicating that competitive firms demand factors even when marginal product is negative.  相似文献

Risk and the Home Equity Conversion Mortgage   总被引:1,自引:0,他引:1  
This article analyzes the risks involved with reverse mortgage insurance and explains the pricing model developed for the Home Equity Conversion Mortgage (HECM) demonstration. The paper demonstrates how borrower longevity, interest rates and property value changes all affect pricing, and why the HECM model focuses on property value as the primary source of uncertainty. It goes on to explain why a random walk specification was chosen to forecast property values, and how the principal limit factors, which determine cash payments to borrowers in the HECM program, are calculated.  相似文献

This paper provides a discussion of dimensions and variables along these dimensions which are believed to be relevant to the control of R&D. Control models gleaned from the literature are compared and classified into a threedimensional taxonomy of control models. The proposed dimensions and the variables associated with them are:
Focus (i.e. project, related projects, programs);
Technical Effort Measurement (Le. project milestones, program goals, organizational agenda);
Financial Orientation (i.e. expense, capital). Of the eighteen potential control models yielded by the taxonomy, nine were found to be reported in use in the literature.
In addition, the authors hypothesize that organizational history, profitability, structure, task environment, type of research conducted, and hierarchical level of control are important determinants of the type of control employed in organizations. How these factors influence the control variables employed in organizations is hypothesized and discussed.  相似文献
