While the political benefits of the coming EU enlargement are relatively easy to identify, its economic and financial consequences are less unequivocal. The following article examines the likely costs and benefits of enlargement to both existing and future Members, and in particular how it will affect Germany, one of the few present EU Member States which has direct borders with acceding states. The article expresses the personal opinions of the author.  相似文献

The arrival of the 2001–2003 recession caused many to suppose that the so-called “New Economy” was now defunct. This article addresses a number of related issues, including the question of the durability and viability of business cycles in the face of the technological developments of the information age. It asks what went wrong with the New Economy and examines its characteristics as well as its remaining possibilities and prospects for the future. Finally, it considers the spread of the Information Economy to Europe, especially to Germany, the country that one might expect to be the leading European player, but which is not at present actually a strong competitor for that role.  相似文献

Returns generated with small firm mutual fund data are used to examine the extent to which identification of a small firm effect is due to the difficulty in measuring the direct and indirect transaction costs involved in investing in the common shares of small capitalization stocks. Little if any evidence of the excess risk-adjusted returns is obtained for either of the period 1978–1983, when the small firm effect was observed, or the period 1984–1989, when it was not. The small firm effect may therefore be attributed to (1) higher direct transaction costs including bid-ask spread and broker fees and (2) higher indirect transaction costs including portfolio management expenses and market impact costs.The authors thank an anonymous referee for helpful comments on an earlier version of this paper, and Brett Salazar for valuable assistance in data collection. Errors remain our own.  相似文献

Expressions for marginal distribution functions of sequential order statistics and generalized order statistics are presented without any restrictions imposed on the model parameters. The results are related to the relevation transform, to the distribution of the product of Beta distributed random variables, and to Meijers G-functions. Some selected applications in the areas of moments, conditional distributions, recurrence relations, and reliability properties are shown. Key words:Order statistics; Generalized order statistics; Sequential order statistics; Record values; Distribution theory; Meijers G-function; Recurrence relations; Reliability properties.  相似文献

This note uses the Theorem of the Alternative to prove new results on the implementability of general, asymmetric auctions, and to provide simpler proofs of known results for symmetric auctions. The tradeoff is that type spaces are taken to be finite.  相似文献
