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.     

Alternative Approaches to Compensation and Producer Rights

When policies are changed, it is not uncommon for losers to be compensated. Economic theory and quantitative analysis are useful in determining the efficiency gains/losses associated with a policy change, but are little help in deciding what the approach to compensation should be. The amount of compensation varies, depending on, in part, the political clout of the parties being negatively affected by a policy change—compensation is what politicians and the sector demanding compensation can agree on. We formulate four approaches to producer compensation within the context of the Ontario Tobacco Transition Program, where producers would have suffered losses in the absence of compensation. The approaches range from providing zero compensation to providing compensation based on the entire value of the tobacco quota. The Canadian government chose the latter and compensated producers for the termination of the tobacco quota program based on an approach that far exceeded other possible compensation approaches.     

Acquisition of Additional Equity Capital by Small Firms – Findings from the National Survey of Small Business Finances

While the importance of venture capital to the growth of small firms has been widely discussed during the past decade, little is known about the acquisition of additional equity capital, especially internal equity capital, by the majority of small firms in the U.S. This paper utilizes the information collected in the Federal Reserve Board’s 1993 and 1998 Small Business Finance Surveys to investigate the acquisition of additional equity capital by small firms. While the importance of public issue markets and venture capital investment in promoting the growth of small dynamic firms cannot be denied, the importance of external equity capital seems to be overstated. Only a very small number of small firms acquired additional external equity capital. It is the internal equity capital, not external, equity, that is one of the major financing sources for most small firms. We found that younger, lower quality firms were more likely to acquire additional internal equity capital than other firms. There appeared to be a “pecking order” of borrowing from internal sources to traditional lenders to non-traditional lenders. In addition, internal equity capital and debt acquired from traditional and non-traditional lenders appeared to be complementary financial resources.     

The Productivity Impact of IT Deployment: An Empirical Evaluation of ATM Introduction

The term 'IT paradox' has been widely used to describe the apparent failure of much economic research to discover significant productivity gains associated with IT investment. In part this has been ascribed to measurement problems associated with both IT inputs and with outputs in IT-intensive industries. The current paper seeks to circumvent these difficulties by taking the ATM as a clearly defined embodied IT application and then using anaugmented production function approach to isolate its productivity effectsacross a sample of UK building societies, over the period of the ATM'sdiffusion. The paper finds no support for the 'IT paradox' and reports large robust and statistically significant productivity gains associated with ATM introduction.     

The Economic Significance of User-Generated Feedback

This paper examines the impact of user-generated feedback on price at a price comparison site or shopbot. It employs a modified hedonic price function to explore the use made by current potential consumers of the experience of past actual consumers in evaluating quality attributes that were not observable when the product was initially launched on to the market. Using a database of daily observations on 211 digital cameras traded on NexTag.com, we find that the product’s star rating, reflecting all the available individual assessments of the product, has a significant negative impact on the discount on the manufacturer’s recommended selling price at which the product is offered.
