Remote operation in environmentally sensitive areas: development of early warning indicators

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.     

When Do Listed Firms Pay for Market Making in Their Own Stock?

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.     

Apple's agency model and the role of most‐favored‐nation clauses

The agency model used by Apple and other digital platforms delegates retail‐pricing decisions to upstream content providers subject to a fixed revenue‐sharing rule. Given competition both upstream and downstream, we consider how, under the agency model, retail prices depend on the firms' revenue‐sharing splits and the degrees to which consumers view the platforms and the goods sold on the platforms to be substitutes. We show that the agency model may not be universally adopted even if adoption would mean higher profits for all firms. Use of most‐favored‐nation clauses in these settings can ensure industry‐wide adoption and increase retail prices.     

Economic Incentives,Business Cycles,and Long‐Term Sickness Absence

We investigate long‐term absenteeism in Norway, on the basis of register data covering 8 years and more than two million absence spells. Key findings are that: (1) a tighter labor market yields lower work resumption rates for persons who are absent, and higher relapse rates for persons who have already resumed work; and (2) the work resumption rates increase when sickness benefits are exhausted, but work resumptions at this stage tend to be short‐lived.     

A Lobbying Approach to Evaluating the Sarbanes‐Oxley Act of 2002

We evaluate the impact of the Sarbanes‐Oxley Act (SOX) on shareholders by studying the lobbying behavior of investors and corporate insiders in order to affect the final implemented rules under SOX. Investors lobbied overwhelmingly in favor of strict implementation of SOX, while corporate insiders and business groups lobbied against strict implementation. We identify firms most affected by the law as those whose insiders lobbied against strict implementation. Such firms appear to be characterized by agency problems, rather than motivated by concerns over compliance costs. Cumulative stock returns during the five and a half months leading up to SOX passage were approximately 7% higher for corporations whose insiders lobbied against SOX disclosure‐related provisions than for similar non‐lobbying firms, consistent with an expectation that SOX would reduce agency problems. Analysis of returns in the post‐passage implementation period suggests that investors' positive expectations with regards to the effects of these provisions were warranted.     

Understanding of consumer behaviour as a prerequisite for environmental protection

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.

     

What are student preschool teachers learning about diet in their education in Norway?

This article is based on a qualitative study on diet education among student preschool teachers. The problem under discussion is: What does a student preschool teacher learn in his education about food, meals, and nutrition? The material used in the article comprises interviews with student preschool teachers at one university and one college in Norway. Preschool teacher education is a three years university college study with bachelor degree. The survey results show that student preschool teachers do not receive even the most element training, when it comes to food and meals, including nutrients, vitamins, and minerals, although education must prepare them for a job outside the kindergarten. Practical cooking was almost completely absent in their education, including hygiene. Most student preschool teachers did not know what fat they were to use in cooking. Food and senses, allergies, and food and culture were not discussed in their education. There was little correlation between the formal curricula in connection with food and meals and the training the preschool teacher students received in their education.
