HOW SHOULD WE MEASURE THE “ECONOMIC” ASPECTS OF WELL‐BEING?

The Human Development Index (HDI) uses GDP per capita to measure “command over resources,” which implicitly makes the strong value judgment that inequality and insecurity do not matter. This paper presents revised estimates of the Index of Economic Well‐Being (IEWB) for the United States, the U.K., Canada, Australia, Germany, Norway and Sweden for the period 1980 to 2001 and demonstrates that replacing an index of the log per capita incomes with our IEWB as the “command over resources” component in the Human Development Index (HDI) affects the level and trend of the HDI, even among affluent nations. Because the IEWB recognizes four dimensions of command over resources (Current effective per capita Consumption flows, Net societal Accumulation of stocks of productive resources, Income Distribution and Economic Security), its use has a particularly large impact where underlying trends in these components diverge (e.g. the U.K. or the United States).     

Uncertain Climate Change in an Intergenerational Planning Model

A three-generation planning model incorporating uncertain climate change is developed. Each generation features a production activity based on capital and an exhaustible resource. An irreversible climate change may occur in period two or three, reducing the productivity for this and the remaining generation. The model is solved by stochastic dynamic programming. If the climate impact and climate change probability is constant, the optimal period one (and two) resource extraction is larger than for the reference case of climate stability. If, however, climate impact and climate change probability increases with increased aggregate resource use, this result is reversed.     

Candidate stability and nonbinary social choice

Summary. The requirement that a voting procedure be immune to the strategic withdrawal of a candidate for election can be formalized in different ways. Dutta, Jackson, and Le Breton (Econometrica, 2001) have recently shown that two formalizations of this candidate stability property are incompatible with some other desirable properties of voting procedures. This article shows that Grether and Plott's nonbinary generalization of Arrow's Theorem can be used to provide simple proofs of two of their impossibility theorems.

Exchange rates and bertrand oligopoly

The impact of exchange-rate changes on industrial prices seems ambiguous. Incomplete and even perverse pass-through has been observed: the import prices in the depreciating country decrease while those in the appreciating country increase. To explain these counterintuitive price reactions we consider a situation of international Bertrand competition: two firms, based in different countries, are selling in both countries simultaneously. The profit-maximizing duopolists set the prices for their products in each of the two markets which are segmented on the demand side. We then study the qualitative effect of an exogenous exchange-rate change on the Bertrand-Nash equilibrium. Under the strong assumption of linear demand and cost functions we have normal exchange-rate pass-through. However, allowing for more general cost structures in this simple static model enables us to show that the import prices in both countries might move in counterintuitive directions.     

Monetary incentives and environmental concern. Effects of a differentiated garbage fee

Market-based instruments, i.e., economic incentives and disincentives, are gaining popularity in environmental policy. However, research on the effectiveness of economic incentives for regulating environmentally relevant consumer behaviour demonstrates convincingly that the implementation of this instrument is based on inadequate assumptions concerning the motivation guiding consumer behaviour. In this paper it is argued that stronger focus should be placed on studying how the regulation instrument influences the perception of the environmentally relevant activity that it was meant to regulate. The attitudes of Danish citizens towards differentiated garbage fees (implying a relatively small economic incentive) and the impact of its implementation on the attitude towards recycling are analysed. The attitude towards differentiated garbage fees is primarily determined by the perceived equity of differentiated garbage fees and its perceived effectiveness with regard to combating waste problems. The most important determinant of the attitudes towards recycling activities is the expected environmental and public benefits. However, empirical support is found for the hypothesis that the use of monetary incentives at the consumer level may re-frame the recycling issue into the sphere where private cost-benefit calculations apply. The negative effects of this re-framing can more than outweigh the positive impact of the monetary incentive on attitudes and behaviour.

Zusammenfassung Monetäre Anreize und Umweltbewutsein. Die Wirkung differenzierter Müllgebühren. Marktkonforme Instrumente wie ökonomische Anreize oder Strafen werden in der Umweltpolitik immer populärer. Allerdings zeigen Forschungsergebnisse über die Wirksamkeit ökonomischer Anreize für die Regulierung umweltrelevanten Konsumentenverhaltens, da\ die Anwendung dieses Instrumentes auf unzweckmä\igen Annahmen über die Motivation beruht, die dem Verbraucherverhalten zugrunde liegt. In diesem Beitrag wird gefordert, da\ die Frage stärker in den Mittelpunkt gerückt werden mu\, wie das Regulierungsintrument die Wahrnehmung des umweltrelevanten Verhaltens beeinflu\t, das reguliert werden soll. Eine empirische Studie untersucht die Einstellungen dänischer Bürger gegenüber differenzierten Abfallgebühren (die einen relativ kleinen ökonomischen Anreiz bieten) und die Wirkung dieser Ma\nahme auf die Einstellung gegenüber der Wiederverwertung. Die Einstellung zu differenzierten Müllgebühren wird in erster Linie durch ihre wahrgenommene Gerechtigkeit bestimmt und durch ihre wahrgenommene Wirksamkeit gegenüber den Müllproblemen. Die wichtigsten Determinanten der Einstellung gegenüber der Müllwiederverwertung sind ihre erwarteten allgemeinen Umweltvorteile. Allerdings sprechen die Daten für die Hypothese, da\ monetäre Anreize das Thema der Müllwiederverwertung auf Verbraucherebene auf das Niveau privater Nutzen-Kosten-Kalkulationen herunterdrücken. Die negativen Effekte dieser Verschiebung könnten die positiven Wirkungen monetärer Anreize auf Einstellung und Verhalten sogar überkompensieren.

Business ethics: Restrictive or empowering?

There is a tendency in the business ethics literature to think of ethics in restrictive terms: what one should not do, and how to control this. Drawing on Lawrence Kohlberg's theory of moral development, the paper focuses on, and draws attention to, another more positive aspect of ethics: the capacity of ethics to inspire and empower individuals, as well as groups. To understand and facilitate such empowerment, it is argued that it is necessary to move beyond Kohlberg's justice reasoning so as to appreciate the value and importance of feeling and care. Accordingly, we draw upon case study material to review the meaning of Kohlberg's higher stages — 5, 6 and 7 — to question the meaning of ethical reasoning. With such deeper understanding of particular ethical codes or practices, it is thought that members of organisations may come closer to thespirit, as opposed to the letter, of ethical conduct in organisations. This, we argue, is consistent with the degree of trust and integrity demanded by leaner, post-bureaucratic ways of organizing and conducting business as well as being personally beneficial to the people involved.Bjørn Kjonstad has recently completed his Masters dissertation.

Assessing the Least Squares Monte-Carlo Approach to American Option Valuation

A detailed analysis of the Least Squares Monte-Carlo (LSM) approach to American option valuation suggested in Longstaff and Schwartz (2001) is performed. We compare the specification of the cross-sectional regressions with Laguerre polynomials used in Longstaff and Schwartz (2001) with alternative specifications and show that some of these have numerically better properties. Furthermore, each of these specifications leads to a trade-off between the time used to calculate a price and the precision of that price. Comparing the method-specific trade-offs reveals that a modified specification using ordinary monomials is preferred over the specification based on Laguerre polynomials. Next, we generalize the pricing problem by considering options on multiple assets and we show that the LSM method can be implemented easily for dimensions as high as ten or more. Furthermore, we show that the LSM method is computationally more efficient than existing numerical methods. In particular, when the number of assets is high, say five, Finite Difference methods are infeasible, and we show that our modified LSM method is superior to the Binomial Model.     

The World Is Not Enough! Small Open Economies and Regional Dependence

In this paper, we explicitly introduce regional factors into a global dynamic factor model. We combine new open economy factor models (emphasizing global shocks) with the recent findings of regional importance in the business cycle synchronization literature. The analysis is applied to a large panel of domestic data for four small open economies. We find that global and regional shocks explain roughly 30 and 20 percent, respectively, of the business cycle variation in all countries. While global shocks have most impact on trade variables, regional shocks explain a relatively large share of the variation in cost variables.     

A Tutorial on Palm Distributions for Spatial Point Processes

This tutorial provides an introduction to Palm distributions for spatial point processes. Initially, in the context of finite point processes, we give an explicit definition of Palm distributions in terms of their density functions. Then we review Palm distributions in the general case. Finally, we discuss some examples of Palm distributions for specific models and some applications.
