Environmental quality indicators: Background,principles and examples from Norway

The need for a simple and general overview of the development in the state of the environment has led to work on environmental indicators in several countries and international organizations. Except for the basic common requirement of providing an overview, the works vary a great deal with regard to final aim, target groups, classification and, hence, choice of indicators. This paper gives an overview of the work carried out in the Central Bureau of Statistics of Norway within this field, with emphasis on the basic principles behind the choice of indicators. A hierarchical system of indicator sets is proposed, and examples of indicators are presented. Also, a brief overview of work carried out elsewhere is included.     

Why Punish? Social reciprocity and the enforcement of prosocial norms

Recently economists have become interested in why people who face social dilemmas in the experimental lab use the seemingly incredible threat of punishment to deter free riding. Three theories with evolutionary microfoundations have been developed to explain punishment. We survey these theories and use behavioral data from surveys and experiments to show that the theory called social reciprocity in which people punish norm violators indiscriminately explains punishment best.JEL Classification: C91, C92, D64, H41 Correspondence to: Jeffrey P.

German rail vehicle construction in the context of market globalisation

Conclusion In the guise of ABB Daimler-Benz Transportation and Siemens, Germany has two powerful systems suppliers in a good position to keep pace with other systems suppliers on global markets. As in the air-travel industry it is conceivable that developments are moving towards a uniform rail technology. Although the buy national principle still dominates procurement practices, and national egos still dominate the development of rail systems (ICE, TGV), growing competition from Japan could force Europe to develop a European system. This would significantly increase the chances of European industry in bidding for international contracts. For this reason the EU should not relent in its efforts to standardise European rail systems.     

Consumer Bankruptcy: A Right or a Privilege? The Role of the Courts in Establishing Moral Standards of Economic Conduct

The Norwegian Consumer Bankruptcy Act was passed 17 July 1992 to give persons with "serious debt problems (. . .) the possibility to gain control over their economy." The Act contains provisions for negotiations between the debtor and the creditors, for court rulings on repayment plans, and for a discharge of the debts not covered by the plan. The origin of the Act was a social welfare approach to the problem of overindebtedness. However, the Act embodies an inherent contradiction in that it also includes moral elements in order to prevent it from exerting a negative influence on the perceived obligation to pay one's debts. This contradiction has given the courts a wide scope of discretion in the application of the Act. As a result, cases are treated differently in different jurisdictions. Some judges put more emphasis on moral evaluations than others. This situation also gives room for strategic action from creditor groups who typically are repeat players in cases of consumer bankruptcy. In this way the more objective, social welfare approach of the Act is undermined.     

REGULATION OF FINANCIAL MARKETS: TOWARD A FOCUSED APPROACH

Regulation of financial markets arose in a simpler time when transactions were carried out face to face on an exchange floor or in a banker's office—when trading was localized and the variety of financial instruments was small. Today the task of regulators is much more difficult. Markets are global, trading takes place in cyberspace, and the variety of financial instruments is limitless.
The initial focus, and still the central concern, of our regulatory system is to ensure full corporate disclosure and transparency of trading markets. But regulation today goes far beyond disclosure requirements. The existing tendency to expand regulation to match the expanding financial markets is likely to be inefficient, unwieldy, and too costly, given the increased complexity and global nature of financial markets. A new approach and a new regulatory mindset are needed—one in which regulators aim to identify and provide only necessary regulation rather than simply continuing to expand regulatory oversight. Such a focused approach to regulation would separate what is regulated from what is not. Those aspects of banking that are essential to the integrity of the payments system would be regulated while other aspects would not. Some securities and derivatives markets would be regulated, while others would not. And market participants would be able to choose which markets to participate in. Given an ever-expanding financial system, such a focused approach to regulation is not only the most cost effective one—it is also likely to prove the only workable alternative to a system that is now under great pressure.     

Internet impacts on supply chain management

The traditional way of managing supply chains has changed dramatically over the last 5 years. Face-to-face management, manual tracking systems, paper-dominated order processing systems, and wired communication links were the primary management tools available to logistics managers. Today, they are obsolete. The article provides an overview of some of the new tools and trends discussed in this issue, including website structure, e-purchasing, electronic marketplaces, building vendor relationships, and the use of the Internet in managing supply chains in China.
