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. 相似文献

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. 相似文献

The idea that for small disturbances the full employment equilibrium is stable while for large disturbances it is unstable was coined by Leijonhufvud in the notion of a corridor. We discuss the existence of a corridor in the standard Keynesian-monetarist textbook macro-model. It turns out that though the full employment steady state of this model may be locally stable — which is the case when the well-known Cagan condition holds — the model is never globally stable. This is due to the inherent non-linearity in the demand for money function, arising from non-negativity of the nominal rate of interest. Thus, perhaps surprisingly, the Cagan condition is both necessary and sufficient for the existence of a corridor in the Keynesian-monetarist model.This note is adapted from a paper presented at the European Meeting of the Econometric Society, Bologna, August 1988. I would like to thank Søren Bo Nielsen and Peter Birch Sørensen (Copenhagen Business School), Thomas Lux (University of Bamberg), and two anonymous referees for helpful comments and suggestions. Remaining errors and shortcomings are mine. 相似文献

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. 相似文献

If some of the returns to migration accrue from returnmigration, the optimal duration of migration may be shorter thanthe feasible duration of migration. We develop a model that providesand highlights conditions under which return migration takesplace even though a reversal of the inter-country wage differentialdoes not occur. In particular, we consider the higher purchasingpower of savings (generated from work abroad) at home than abroadas a motive for return migration. Inter alia, our model producesa negative relationship between the optimal duration of migrationand the purchasing power differential and in some (but not all)cases, a negative relationship between the optimal duration ofmigration and the wage abroad. In addition, and contrary to ourprior anticipation, our utility maximization analysis suggeststhat East-West migration will tend to be temporary while inter-EuropeanCommunity (or intra-West European) migration will likely be permanent. 相似文献

This paper examines if the level of voluntary disclosure affects information asymmetry for industrial companies listed on the Copenhagen Stock Exchange. Economic theory suggests that disclosing more information should lower the information asymmetry component of a firm's cost of capital [Leuz, C., & Verrecchia, R. E. (2000)]. The results indicate that voluntary disclosure is negatively associated with proxies for information asymmetry. The results are robust even after controlling for various firm characteristics introduced in related literature. Despite differences in institutional settings the findings in our paper are similar to the ones based on US data. 相似文献

Based on a purely rank-oriented approach, this empirical study analyzes to what extent superior firm size in German life industry
generally translates into corporate advantages for the companies concerned. It turns out that while modest advantages with
some criteria are measurable, any such benefits are usually outweighed by unquantifiable factors unrelated to firm size. Confining
the study to a highly homogeneous subgroup of life insurers, however, reveals substantial corporate advantages in a number
of areas, thereby confirming well-established theoretical reasoning. 相似文献
