We explore in this paper the relationship between equity‐sensitive population health evaluation measures and normative concerns for relative comparisons of health gains. Such a relationship allows us to characterize focal equity‐sensitive models for the evaluation of population health. Instances are the so‐called multiplicative Quality Adjusted Life Years (QALYs) and multiplicative Healthy Years Equivalents (HYEs), as well as generalizations of the two. Our axiomatic approach assumes social preferences over distributions of individual health states experienced in a given period of time. It conveys informational simplicity, as it does not require information about individual preferences on health.  相似文献

Monetary policymakers often seem to have preferences for a stable interest rate, in addition to stable inflation and output. In this paper, we investigate the implications of having an interest rate level term in the loss function when the policymaker lacks commitment technology. We show that such preferences may become self‐defeating, in the sense that they generate a less stable interest rate than in the case without preferences for interest rate stability.  相似文献

Exploration and production of oil and gas in certain sensitive areas such as the Barents Sea and Lofoten is controversial and further expansion depends on the ability to avoid harmful spills. One way of improving the ability to avoid such spills is to use early warning indicators. The objective of the work presented in this paper is to describe and compare strengths and weaknesses of different approaches for the development of early warning indicators. The approaches that have been compared are: safety performance-based methods; risk-based methods; incident-based methods; and resilience-based methods. There are pros and cons with all methods. All methods are very favorable with respect to some characteristics and at the same time very unfavorable to some other characteristics. They are also different in terms of scope and depth of analysis. This suggests that we should be flexible with respect to the choice of methods, and preferably use more than one method. Thus, the main conclusion is that it is favorable to have the possibility to use several different methods for the establishment of early warning indicators.  相似文献

The purpose of this study was to investigate the knowledge and attitudes of adolescents in Tromsø relating to nutrition; whether pupil behaviour and attitudes regarding nutrition had changed in the tenth grade compared with the eighth grade; and whether this was linked to pupils’ home economics lessons in grade 9. In total, 606 adolescents (321 boys and 285 girls) were studied on two different occasions – 2002 and 2005. A food frequency questionnaire focusing on 16 different food and beverage groups was used. It investigated knowledge and attitudes, the amounts of food items consumed and the socio‐economic situation of the participants and their families. The study produced interesting findings. The boys had surprisingly low knowledge of fruit and vegetables that did not change in a positive direction, between the eighth and tenth grades. The change among the girls was very small and therefore this study concludes that the teaching of home economics had no significant influence on the pupils’ knowledge of and attitudes towards eating fruit and vegetables. The study of home economics does not appear to enhance adolescents’ skills and attitudes to the extent expected from the curriculum. But there are gender differences at both grades. Changes in the home economics course are necessary to improve children's and adolescents’ knowledge and attitudes. Increased focus on the scope and variety of teaching methods will be a key to improvement. Future research is required to understand the potential of the home economics curricula to change adolescents’ knowledge about and attitudes to home economics in Norway.  相似文献

We study the exploration and development of oil and gas fields in the U.S. over the period 1955-2002. We make four contributions to explain the economic evolution of the oil and gas industry during this period. First, we derive a testable model of the dynamics of competitive oil and gas field exploration and development. Second, we show how to empirically distinguish Hotelling scarcity effects from effects due to technological change. Third, we test these hypotheses using statewide panel data of exploration and development drilling. We find that the time paths of exploration, development and total wells drilled are dominated by Hotelling scarcity effects. Finally, we offer an explanation for why fixed costs from exploration can make the contracting equilibrium in the mineral rights market efficient.  相似文献

A number of the environmental problems threatening our habitat are to a greater or lesser extent caused by present consumer lifestyles. More sustainable lifestyles cannot be obtained without marked changes in consumer attitudes and consumer behaviour. To arrive at a synthesis of what is known, and of what needs to be known, about the determinants of consumer behaviour with an environmental impact, a frame of reference employing three main classes of variables is used: motivation, ability, and opportunity. Apart from surveying the research of others, illustrations are given from studies carried out by the group of researchers at the Aarhus School of Business to which the authors belong; this research has been mainly concerned with waste handling and recycling. In addition, various strategies for changing consumer behaviour in an environment-friendly direction are considered. Information, moral arguments, and economic incentives are discussed as instruments for change. In setting goals for change strategies, broad goals such as heightened psychic and communicative activity in matters of environmental concern ought to be considered as an alternative to the elicitation of very specific behaviours.
Zusammenfassung Einsicht in das Vehalten von Konsumenten als Voraussetzung für den Schutz derZahlreiche Umweltprobleme, die unsere Lebensgrundlagen bedrohen, werden Umwelt. mehr oder weniger von den Lebensgewohnheiten der Konsumenten verursacht. Lebensstile, die demgegenüber eher als nachhaltig gelten können, könen nur durch deutliche Veränderungen im Bereich der Einstellungen und des Verhaltens von Konsumenten erzielt werden.Der Beitrag liefert eine Zusammenschau dessen, was über die Einflu\faktoren auf das Verbraucherverhalten bekannt ist, soweit es Umweltwirkungen hat, und zeigt ebenso auf, was dazu noch nicht bekannt ist. Als Bezugsrahmen wählt er ein Modell, das Merkmale auf den drei Ebenen Motivation, Fähigkeit und Möglichkeit unterscheidet.Au\er einem überblick über Forschungsergebnisse, die in der Literatur berichtet werden, schildert der Beitrag auch Ergebnisse der Forschergruppe an der Aarhus School of Business, zu der die beiden Autoren des Beitrages gehören. Diese Ergebnisse beziehen sich in erster Linie auf Abfallverhalten und Wiederverwertung.Schlie\lich werden verschiedene Strategien zur Veränderung des Verbraucherverhaltens in umweltfreundlicher Richtung behandelt, vor allem Informationen, moralische Argumente und ökonomische Anreize. Bei der Formulierung von Zielen für solche Veränderungen sollten breite Zielsetzungen, wie z.B. gesteigerte psychische und kommunikative Aktivität in Umweltangelegenheiten, als Alternative zur Erreichung sehr spezifischen Verhaltens erwogen werden.

A recent innovation in the equity markets is the introduction of market maker services procured by the listed companies themselves. Using data from the Oslo Stock Exchange, we investigate what motivates issuing firms to pay to improve the secondary market liquidity of their listed shares. By examining the timing of market maker hirings relative to corporate events, we show that hirings are more likely when the firm will interact with the capital markets in the near future. Futhermore, a typical firm employing a designated market maker is more likely to raise capital, repurchase shares, or experience an exit by insiders.  相似文献
