Assessing the technology contribution to value added

Technology and knowledge are two key components for economic growth; however, the two concepts are not consensually defined. This paper proposes a model to assess and quantify the technology contribution to the value-adding process. The methodological approach implied building an operational concept for technology that is independent of the concepts of knowledge and capital. As such, technology could be interpreted and quantified as an input parameter in a new production model. This model interprets and assesses, separately, the value contributions of the uses of technology, of knowledge and of capital in a production process, defining the Technology Index for that process. The model is applied to manufacturing sectors of seven European countries, quantifying their respective dependences on technology. A comparison of the Technology Index proposed here is made with the OECD's Technology Intensity factor, arguing that the former reflects the technology dependence better that the latter. Accordingly, a criterion for classifying the economic sectors' dependence on technology is proposed. A main contribution from this study is an objective classification criterion for technology dependence of firms and economic sectors. It also provides an easy benchmark procedure for knowledge and capital dependence between firms and sectors.     

The Creation of Value Through Corporate Reputation

The relationship between social and financial performance (CSP – FP) has been a main objective in the literature on business management, as it would provide an economic justification for the social investment insofar as it contributes to the creation of value. This relationship has been empirically tested by several authors though without using a theoretical model that sustains this relationship. The aim of this article is to propose a theoretical model of the process of the creation of value from the reputation generated by companies, integrating the factors that have been shown to be more relevant in this process from previous research, in such a way that hypotheses are put forward regarding the existence of this relationship and the factors that determine it. Finally, an empirical test is performed using the 100 most prestigious companies operating in Spain during 2004.     

Ordering univariate distributions by entropy and variance

This paper examines the role of variance and entropy in ordering distributions and random prospects. There is no universal relation between entropy and variance orderings of distributions. But we place their relationship in the context of a stronger ordering relation known as dispersion ordering. Further, some conditions are identified under which variance and entropy order similarly when continuous variables are transformed. We also analyze parametric changes which do not disturb the agreement between these rankings. The results are conveniently tabulated in terms of distribution parameters.     

Convergence within the EU: Evidence from Interest Rates

The economic and political changes which are taking place in Europe affect interest rates. This paper develops a two-factor model for the term structure of interest rates specially designed to apply to EMU countries. In addition to the participant country's short-term interest rate, we include as a second factor a 'European' short-term interest rate. We assume that the 'European' rate follows a mean reverting process. The domestic interest rate also follows a mean reverting process, but its convergence is to a stochastic mean which is identified with the 'European' rate. Closed-form solutions for prices of zero coupon discount bonds and options on these bonds are provided. A special feature of the model is that both the domestic and the European interest rate risks are priced. We also discuss an empirical estimation focusing on the Spanish bond market. The 'European' rate is proxied by the ecu's interest rate. Through a comparison of the performance of our convergence model with a Vasicek model for the Spanish bond market, we show that our model provides a better fit both in-sample and out-of sample and that the difference in performance between the models is greater the longer the maturity of the bonds.

Raising rivals' costs: The entry of an upstream monopolist into downstream markets

A regulated upstream monopolist provides an input to firms in a downstream market. If the monopolist enters the downstream market, a natural concern is that it will act so as to raise its downstream rivals' costs. An offsetting incentive is that a higher downstream price will reduce demand for the input, which reduces the monopolist's profit. Conditions under which one incentive dominates the other are derived. The monopolist may desire to lower its downstream rivals' costs rather than raise them. These findings suggest that regulatory policy towards such downstream entry should not focus exclusively on the ability to discriminate.     

Global Strategy in the Internet Era

This article examines the joint effects on business strategy of the Internet and globalization. It develops a framework for evaluating how the Internet affects the globalization potential of individual industries and the global strategies that companies should adopt. The impact of the Internet will not be uniform. Not only do its direct effects vary from one industry to another, but also it speeds up globalization at different rates in different industries. The article shows how to use the Internet to support five types of global strategy: market participation, products and services, activity location, marketing, and competitive moves.     

The geography of tourism: An introduction

The geography of tourism is limited by a dearth of published research in geographic journals, the relatively few individuals who actively participate in the sub-discipline, and the lack of prestige the subject matter specialty has in geography. Despite these imperfections geographers make important contributions to the study of tourism because of their unique point-of-view. This characteristic perspective is seen in the context of a conceptual frame-of-reference which consists of a matrix based on two trichotomies. An analysis and interpretation of this framework and its application to the nine substantive articles included in the special issue constitute a majority of the article.     

Quasitransitive social preference: why some very large coalitions have very little power

Summary. If only the strict part of social preference is required to be transitive then Independence of Irrelevant Alternatives implies that there is a coalition containing all but one individual that cannot force x to be socially ranked above y for at least half of the pairs of alternatives (x,y).
