    Description: Immigrants in Germany display a poor earnings performance relative to natives. Arguing that human capital endowments identify earnings potentials rather than actual earnings, this paper estimates a stochastic earnings frontier and searches for systematic differences between natives and migrants in terms of distance to the frontier. GSOEP-Data of the year 2000 is used for estimation. The empirical results clearly support the frontier assumption, but – surprisingly – find natives and immigrants at about the same distance to the frontier. Assuming a halfnormal distribution of the wage-inefficiency term, both groups transformed on average a modest 81% share of their potential income into market earnings. Due to the similar positions of natives and immigrants relative to the frontier, the wage discrimination hypothesis is rejected. Actually, human capital differentials are clearly the most important source for wage inequality. The earnings frontiers of immigrants from Eastern Europe as well as from Turkey are steeper than the respective frontier of natives, which supports the assimilation hypothesis. No assimilation is found for migrants from the European Union and from the former Yugoslavia.

    Description: Using an exhaustive panel dataset of the German agricultural sector, this paper is evaluating the relationship between climate conditions and land prices. The main advantage of this so-called hedonic approach is the consideration of the full range of adaptation options to the climatic environment. A Box-Cox form is employed to allow for very flexible relationships between land prices, warmth, moisture, and different socioeconomic variables. In a second step, the estimated results are used to forecast the impact of global climate change on the farming sector. The results show that a change of the temperature level has stronger impacts than a change of rainfall. Using a greenhouse warming scenario, German farmers are expected to be winners of climate change at least in the short run. Maximum gains are estimated with a temperature increase of +1.0°C against the current levels. Should the temperature increase surpass 1.8°C, however, the impact on the farming sector is clearly negative.

    Description: This study uses the concept of shadow prices for measuring the impacts of climate change. Estimation of a restricted profit function rather than a cost or a production function increases the explanatory power of the agroclimate approach because of an endogenous output structure. Using micro-based panel data on Western German farmers, the results im-ply that the agricul-tural production process is significantly influenced by climate conditions. By linking this model with a climate-change scenario, a remarkable positive shadow value is found for the German agricultural sector. Interestingly, the spatial distribution of the gains shows no concentration on those regions, which currently suffer from insufficient temperature. Finally, the importance of an endogenous output structure is confirmed by the finding that the de-sired product mix will drastically change.

    Notes: Abstract Based on an unbalanced panel of all Bavarian cooperative banks for the years of 1989--97, which includes information on 283 mergers, we analyze motives and cost effects of small-scale mergers in German banking. Estimating a frontier cost function with a time-variable stochastic efficiency term, we show that positive scale and scope effects from a merger arise only if the merged unit closes part of the former branch network. When we compare actual mergers to a simulation of hypothetical mergers, size effects of observed mergers turn out to be slightly more favorable than for all possible mergers. Banks taken over by others are less efficient than the average bank in the same size class, but exhibit, on average, the same efficiency as the acquiring firms. For the post-merger phase, our empirical results provide no evidence for efficiency gains from merging, but point instead to a leveling off of differences among the merging units.

    Description: Die Krise der Medienindustrie ist im wesentlichen eine Krise des Werbemarktes. Angesichts eines Beitrages der Werbung in Höhe von zwei Dritteln zum Umsatzaufkommen der Massenmedien überrascht dies nicht, wird aber durch das vorliegende Zahlenmaterial noch einmal bestätigt. Dieser Beitrag geht der Frage nach, ob der beobachtete Einbruch die historischen Zyklen der Werbebranche bestätigt, oder ob ein Strukturbruch und damit ein Zerfall der bisherigen Zyklusmuster stattgefunden hat. Hierzu werden in einem ersten Schritt die Zykluslängen der Zeitreihe mit Hilfe der Spektralanalyse identifiziert. In einem zweiten Schritt werden die wichtigsten Zyklen als erklärende Variable in ein Regressionsmodell eingefügt, um deren Erklärungsbeitrag zu den historisch beobachteten Veränderungsraten des Werbemarktes zu bestimmen. Als Datenmaterial stehen die Werbeausgaben von 1960 bis 2003 auf Jahresbasis zur Verfügung, wobei die Werbeausgaben nach fünf Mediengattungen differenziert sind. Es zeigt sich, dass die beobachteten Veränderungsraten relativ gut durch das gemessene Zyklusgefüge mit sich überlagernden Einzelzyklen erklärt werden kann. Der Test auf Strukturbruch wird verworfen ? zumindest bislang kann somit davon ausgegangen werden, daß die Krise des Werbemarktes das historische Zyklusmuster eher bestätigt als zerstört.
    Description: The current crisis of the media industry is a consequence of poor revenues from the advertising market. Actually, advertising revenues are contributing more than 60% to the total revenues of German mass media, thus dominating the economic performance of media firms. This empirical contribution seeks to understand the cyclical behavior pattern of the advertising market and to test if the recent slump in advertising demand follows this cyclical pattern. In a first step, spectral analysis is used to identify potential cycle lengths. In a second step, the explanatory power of cycles for advertising demand is evaluated by inserting the most important cycle lengths into a regression model. All estimations are based on yearly data of the German advertising market from 1960 to 2003, differentiated by five types of media. The results underline a strong influence of overlapping cycles for the advertising market, with advertising in magazines being the only exception. There is no statistical support for the hypothesis of a structural break during the recent slump in advertising demand.

    Description: Der Telekommunikationssektor ist diejenige Netzindustrie, die innerhalb der Europäischen Union dem wohl ambitioniertesten Reformprozeß unterworfen wurde. Deregulierung und Privatisierung sind die wesentlichen Bausteine, von denen dauerhaft niedrigere Preisniveaus, beschleunigter technischer Fortschritt und gesamtwirtschaftlich höhere Wachstumsraten erwartet werden. Dieser Beitrag setzt zum einen an dem schon weit vorangeschrittenen Reformprozeß an und faßt die wichtigsten Maßnahmen sowie die bisherigen Umsetzungserfolge zusammen. Zum anderen wird auf die spezifische Situation der Mehrwertdienste im neuen Regulierungsumfeld eingegangen, wobei der sogenannte bottleneck des früheren Alleinanbieters eine zentrale Rolle spielt. Die Zugriffsbedingungen auf dieses bottleneck sind von besonderer Brisanz, da zum einen häufig keine Alternative zum etablierten Anbieter existiert, zum anderen die ehemaligen Staatsmonopolisten bis heute vertikal integriert sind und selbst als Anbieter von vielen Mehrwertdiensten tätig sind.
    Description: During the last years many network industries experienced drastic changes in their regulatory framework, which were driven by reforms on the EU-level. The telecommunication sector is the frontrunner of this process. Motivated by the hope for higher productivity and increasing macroeconomic growth rates, important deregulation and privatization measures were undertaken. The first topic of this paper is to summarize these regulatory changes and their impacts. As a second topic, the specific situation of value added services,which are dependent on the access to the network bottleneck, is analyzed. The economic analysis of these access conditions is extremely relevant, because many value added services do not have a realistic alternative to the established bottleneck provider. Furthermore, and perhaps more important, the former monopolists are downstream integrated and therefore rivals on the level of many value added services.

    Description: This study assesses the impact of the single market program (SMP) and the European monetary union (EMU) on the German banking sector. As a main result, the introduction of the EMU can be assessed as more important for the German banking system than the SMP because of the relative liberal conditions prior to the SMP. To maintain or enhance profitability in an environment of decreasing margins, all banks will increase their efforts to reduce costs. On the product side, the disintermediation process is expected to speed up. As a consequence, the traditional system of universal banks could be somewhat changed: A partial retreat of savings as well as cooperative banks from investment banking, accompanied by increasing market shares in the branch-based retail business. For commercial banks, the consultation-intense investment business is very attractive. On the retail sector, a specialization on direct banking allows for additional customers from abroad as well as for high growth rates in the brokerage business.

    Notes: Über Einkristallaufnahmen von Lithiummetastannat wurden die Strukturen folgender, durch die Analyse bestätigter Verbindungen ermittelt: \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm Li}_{\rm 2} {\rm SnO}_{\rm 3} {\rm,}\,{\rm Li}_{\rm 2} {\rm TiO}_{\rm 3},\,{\rm Na}_{\rm 2} {\rm SnO}_{\rm 3},\,{\rm Na}_{\rm 2} {\rm ZrO}_{\rm 3} \,{\rm und \,Na}_{\rm 2} {\rm PbO}_{\rm 3} . $$\end{document} Die Verbindungen erwiesen sich über Intensitätsrechnungen an Hand der Pulveraufnahmen als isotyp. Die monokline Elementarzelle gehört der Raumgruppe C2h6 = C 2/c an und enthält acht Molekeln. Die Struktur läßt sich auch durch eine Zelle mit rhombischem Umriß und dreifachem Volumen beschreiben. Der manchen Netzsilicaten verwandte pseudo-hexagonale Charakter des Gitters läßt sich an dem Verhältnis a-Achse: b-Achse = 1:√3 erkennen. Wie dort bilden die Sauerstoffionen eine kubisch-dichteste Kugelpackung und treten in der Zelle als Schichten auf, während die Kationen in besonderer Anordnung die Zwischenschichten dazu bilden.Na2PbO3 tritt in einer zweiten Modifikation auf, die der kubischen Form von Li2TiO3 entspricht.Die Herstellung von Na2TiO3 und Li2ZrO3 wurde - wie bei den anderen Verbindungen über Reaktion von Alkalicarbonat und Metalloxyd im festen Zustand versucht. Die Pulveraufnahmen der nicht analysierten Reaktionsprodukte ergaben zwar ähnliche, aber doch an wesentlichen Stellen veränderte Reflexfolgen, so daß keine Isotypie mit den übrigen Verbindungen angenommen werden darf.
