Mehr als ein Jahr nach dem EU-rechtlich vorgegebenen Endtermin wurde im Juli 2005 das neue Energiewirtschaftsgesetz verabschiedet.
Von welchen Zielen geht dieses Gesetz aus? Wie lauten seine wichtigsten Neuregelungen? Und welche Auswirkungen sind von ihnen
zu erwarten? 相似文献

Gross stocks of foreign assets have increased rapidly relative to national outputs since 1990, and the short-run capital gains
and losses on those assets can amount to significant fractions of GDP. These fluctuations in asset values render the national
income and product account measure of the current account balance increasingly inadequate as a summary of the change in a
country's net foreign assets. Nonetheless, unusually large current account imbalances, especially deficits, should remain
high on policymakers' list of concerns, even, for the richer and less credit-constrained countries. Extreme imbalances signal
the need for large and perhaps abrupt real exchange rate changes in the future, changes that might have undesired political
and financial consequences given the incompleteness of domestic and international asset markets. Furthermore, of the two sources
of the change in net foreign assets—the current account and the capital gain on the net foreign asset position—the former
is better understood and more amenable to policy influence. Systematic government attempts to manipulate international asset
values in order to change the net foreign asset position could have a destabilizing effect on market expectations. JEL no.

This paper provides some empirical evidence on one of the most controversial theoretical implications of the new open economy
literature, which refers to the role of the current account in the international monetary transmission mechanism. In order
to throw some light on this issue, two structural VAR models are estimated separately for 14 industrialized countries. The
main empirical results highlight the importance of the role of nominal disturbances for current account fluctuations. Additionally,
it is found that expansionary nominal shocks generate temporary current account surpluses, whose size is positively correlated
with the openness of the individual countries. JEL no. C32, E40, F41, F42 相似文献

This paper is the first attempt to analyze ITC Commissioner voting behavior on sunset reviews of antidumping cases. Sunset
determinations entail greater complexity than initial antidumping investigations because ITC commissioners must account for
the impact of dumping protection as well as competitive forces on industry conditions. Empirical findings indicate that ITC
voting is based on both sunset regulation and nonstatutory factors. Results reveal apparent biases against Chinese competitors
and poorer nations generally, and favorable treatment toward U.S. steel producers and high-wage industries. There is also
evidence of preferential treatment of industries located in states of Senate oversight committee members. JEL no. F13 相似文献

Productivity and the Euro-Dollar exchange rate 总被引:1,自引:1,他引:0
This article analyses the impact of productivity developments in the United States and the euro area on the euro-dollar exchange
rate. The article presents a new measure of relative average labour, productivity (ALP) which does not suffer from the biases
implicit in readily available relative ALP data. Importantly, the patterns of these series differ widely. Employing the Johansen
cointegration framework, four models are estimated using four different productivity proxies. Our results indicate that the
extent to which productivity can explain the euro depreciation varies with the productivity proxy used: readily available
measures explain most, our new, preferred measure least. In all models, however, productivity can explain only a fraction
of the actual euro depreciation experienced in 1999–2000. JEL no. F31, C32, O47

In the 1980s, the Chinese regime took a number of piecemeal steps toward economic liberalization. This process accelerated
impressively in the 1990s. This paper reports an empirical study into the determinants of the emerging pattern of Chinese
trade (export and import) intensities in the liberalization decade by exploring international trade statistics for 1993 and
1999. Four models are estimated that explain the shifts in the export and import intensities of the trade with different trade
partners in the 1993–1999 period. The estimation results reveal differences for export vis-à-vis import trade intentities,
as well as for 1993 compared to 1999. For example, the political determinants of trade intensities that were still very important
in 1993 have been moved to the background by economic explanations in 1999. JEL no. F14 相似文献

On the eve of enlargement of the European Union from fifteen to twenty-five Member States, this article focuses on economic developments in 2003 and prospects for 2004 and 2005 in the European Union, especially in the euro area, the state of play on structural reform, before concluding with some reflections on enlargement. 相似文献

Ziel des Beitrags ist die Beantwortung der Frage, welche Faktoren die Nutzung von Fernsehserien erkl?ren k?nnen. Kann sie
im Wesentlichen auf Habitualisierung und strukturelle Rahmenbedingungen zurückgeführt werden, oder l?sst sie sich dadurch
erkl?ren, dass die Erwartungen an die Qualit?t von Fernsehserien und die Wahrnehmung von Qualit?tseigenschaften der verschiedenen
Serien zwischen den Rezipienten variieren? Zun?chst werden die theoretisch relevanten Faktoren für ein Modell der subjektiven
Qualit?tsauswahl identifiziert und operationalisiert. Anschlie?end wird in einer empirischen Studie geprüft, ob diese Faktoren
einen Einfluss auf die Nutzung der Fernsehserien haben. Die Untersuchungsergebnisse zeigen, dass die drei Elemente des theoretischen
Ansatzes — Qualit?tserwartungen, Qualit?tswahrnehmungen und Qualit?tsurteile — die Seriennutzung zu einem betr?chtlichen Teil
erkl?ren k?nnen. Der Vorteil dieses Ansatzes gegenüber dem Uses and Gratifications Approach besteht darin, dass die Eigenschaften
des Angebots im Mittelpunkt stehen. Damit wird es m?glich, Aussagen darüber zu machen, welche wahrgenommenen Merkmale des
Angebots für die Nutzungsentscheidungen der Rezipienten relevant sind. 相似文献

We propose here a theory of cylindrical stochastic integration, recently developed by Mikulevicius and Rozovskii, as mathematical background to the theory of bond markets. In this theory, since there is a continuum of securities, it seems natural to define a portfolio as a measure on maturities. However, it turns out that this set of strategies is not complete, and the theory of cylindrical integration allows one to overcome this difficulty. Our approach generalizes the measure-valued strategies: this explains some known results, such as approximate completeness, but at the same time it also shows that either the optimal strategy is based on a finite number of bonds or it is not necessarily a measure-valued process.Received: November 2002, Mathematics Subject Classification:

Liquidity risk and arbitrage pricing theory 总被引:2,自引:0,他引:2
Classical theories of financial markets assume an infinitely liquid market and that all traders act as price takers. This theory is a good approximation for highly liquid stocks, although even there it does not apply well for large traders or for modelling transaction costs. We extend the classical approach by formulating a new model that takes into account illiquidities. Our approach hypothesizes a stochastic supply curve for a securitys price as a function of trade size. This leads to a new definition of a self-financing trading strategy, additional restrictions on hedging strategies, and some interesting mathematical issues.Received: 1 November 2003, Mathematics Subject Classification:
