Bilanz
Im Sommersemester 2000 wurde in der Bibliothek der Fachhochschule Nordostniedersachsen an den Standorten Lüneburg, Suderburg und Buxtehude eine Nutzerbefragung unter 800 Studierenden durchgeführt. Die nach dem Zufallsprinzip ausgewählten Studierenden erhielten einen umfangreichen Fragebogen per Post zugeschickt, den 159 ausfüllten und zurücksandten. Es wurden Fragen zum Nutzungsverhalten und zur Zufriedenheit mit den Dienstleistungen der Bibliothek gestellt. Die Auswertung der Befragung erfolgte mit dem Statistikprogramm SPSS durch den Fachbereich Wirtschaftspsychologie, der auch den vorliegenden Ergebnisbericht erstellte.

Der vorliegende Aufsatz beschäftigt sich mit der zukünftigen Entwicklung des Electronic Government (E-Government).
Der Aufsatz handelt vom 'Cyberspace' als Utopie unserer Informationsgesellschaft
Many public goods are characterized by rivalry and/or excludability. This paper introduces both non-excludable and excludable public inputs into a simple endogenous growth model. We derive the equilibrium growth rate and design the optimal tax and user-cost structure. Our results emphasize the role of congestion in determining this optimal financing structure and the consequences this has in turn for the government’s budget. The latter consists of fee and tax revenues that are used to finance the entire public production input and that may or may not suffice to finance the entire public input, depending upon the degree of congestion. We extend the model to allow for monopoly pricing of the user fee by the government. Most of the analysis is conducted for general production functions consistent with endogenous growth, although the case of CES technology is also considered.
This paper discusses the emergence of endogenous redistributive cycles in a stochastic growth model with incomplete asset markets and heterogeneous agents, where agents vote on the degree of progressivity in the taxñtransferñscheme. The model draws from BÈnabou (1996) and ties the bias in the distribution of political power to the degree of inequality in the society, thereby triggering redistributive cycles which then give rise to a nonlinear, cyclical pattern of savings rates, growth and inequality over time.
Many plant-level studies find that average wages in exporting firms are higher than in non-exporting firms from the same industry and region. This paper uses a large set of linked employer-employee data from Germany to analyze this exporter wage premium. We show that the wage differential becomes smaller but does not completely vanish when observable and unobservable characteristics of the employees and of the work place are controlled for. For example, blue-collar (white-collar) employees working in a plant with an export-sales ratio of 60 percent earn about 1.8 (0.9) percent more than similar employees in otherwise identical non-exporting plants.
In the course of railway reforms at the end of the last century, European national governments, as well the EU Commission, decided to open markets and to separate railway networks from train operations. Vertically integrated railway companies argue that such a separation of infrastructure and operations would diminish the advantages of vertical integration and would therefore not be suitable to raise economic welfare. In this paper, we conduct a pan-European analysis to investigate the performance of European railways with a particular focus on economies of scope associated with vertical integration. We test the hypothesis that integrated railways realize economies of joint production and, thus, produce railway services on a higher level of e±ciency. To determine whether joint or separate production is more e±cient we apply an innovative Data Envelopment Analysis super-e±ciency bootstrapping model which relates the e±ciency for integrated production to a virtual reference set consisting of the separated production technology and which is applicable to other network industries as energy and telecommunication as well. Our ¯ndings are that for a majority of European Railway companies economies of scope exist.
Using panel data from Spain Farinas and Ruano (IJIO 2005) test three hypotheses from a model by Hopenhayn (Econometrica 1992): (H1) Firms that exit in year t were in t-1 less productive than firms that continue to produce in t. (H2) Firms that enter in year t are less productive than incumbent firms in year t. (H3) Surviving firms from an entry cohort were more productive than non-surviving firms from this cohort in the start year. Results for Spain support all three hypotheses. This paper replicates the study using a unique newly available panel data sets for all manufacturing plants from Germany (1995 – 2002). Again, all three hypotheses are supported empirically.

Im Jahr 1991 fand in Lueneburg im dortigen Museum ein Ausstellungsprojekt statt, geplant und realisiert von Lehrenden und Studierenden unserer Universitaet. Anna Oppermann war eine der eingeladenen Kuenstlerinnen und steuerte ihr "Friduttchen"-Ensemble bei. Aus diesem Treffen entstand die Idee, den Versuch zu wagen, ihre hoch komplexe, fragile, vergaengliche Arbeit mit den informatischen und kunstwissenschaftlichen Methoden zu dokumentieren, die wir Gelegenheit hatten, ihr vorzustellen. Im folgenden Jahr entstanden dann in enger Absprache mit der Kuenstlerin erste Versionen eines digitalen Archivs ihres Ensembles "Umarmungen, Unerklaerliches und eine Gedichtzeile von R.M.R." Der Beitrag berichtet ueber das Projekt und die Dokumentation der Arbeit Anna Oppermanns mit dem XML-Standard PeTAL.
This paper contributes to the flourishing literature on exports and productivity by using a unique newly available panel of exporting establishments from the manufacturing sector of Germany from 1995 to 2004 to test three hypotheses derived from a theoretical model by Hopenhayn (Econometrica 1992): (H1) Firms that stop exporting in year t were in t-1 less productive than firms that continue to export in t. (H2) Firms that start to export in year t are less productive than firms that export both in year t-1 and in year t. (H3) Firms from a cohort of export starters that still export in the last year of the panel were more productive in the start year than firms from the same cohort that stopped to export in between. While results for West Germany support all three hypotheses, this is only the case for (H1) and (H2) in East Germany.
This paper uses data from the German Socio-Economic Panel for the years 2000 to 2005 to study the earnings differential between self- and dependent employed German men. Constructing a counterfactual earnings distribution for the self-employed in dependent employment and using quantile regression decompositions we find that the earnings differential over the distribution cannot be explained by differences in endowments. Furthermore, low-earning self-employed could earn more in dependent employment. Finally, the observed earnings advantage for the self-employed at the top of the earnings distribution is not associated with higher returns to observable variables.
Strong sustainability, according to the common definition, requires that different natural and economic capital stocks have to be maintained as physical quantities separately. Yet, in a world of uncertainty this cannot be guaranteed. To therefore define strong sustainability under uncertainty in an operational manner, we propose to use the concept of viability. Viability means that the different components and functions of a dynamic, stochastic system at any time remain in a domain where the future existence of these components and functions is guaranteed with sufficiently high probability. We develop a unifying and general ecological-economic concept of viability that encompasses the traditional ecological and economic notions of viability as special cases. It provides an operational criterion of strong sustainability under conditions of uncertainty. We illustrate this concept and demonstrate its usefulness by applying it to livestock grazing management in semi-arid rangelands.
Empirische Befunde zeigen, dass exportierende niedersächsische Industriebetriebe produktiver als vergleichbare nicht exportierende Betriebe sind, wobei diese Unterschiede bereits vor dem Exportstart bestehen (also eine Selbstselektion der produktiveren Betriebe auf Exportmärkte stattfindet), während es für Lerneffekte im Zusammenhang mit Exportaktivitäten und daraus folgendem höherem Produktivitätswachstum in exportierenden Betrieben keine Evidenz gibt. Mit neu verfügbaren Paneldaten für deutsche Industriebetriebe und auf der Grundlage der Ergebnisse einer neuen international vergleichenden Studie zeigt dieser Beitrag, dass die Produktivitätsprämie in Niedersachsen so hoch wie im Durchschnitt für den Rest von Westdeutschland, aber höher als für Ostdeutschland ist. Niedersachsen nimmt im internationalen Vergleich damit einen Mittelplatz unter den hier betrachteten Ländern ein. Ein interregionaler bzw. internationaler Vergleich der Größenordnungen der Selektions- und Lerneffekte ist hier allerdings nicht möglich. Zwar zeigt eine Gegenüberstellung der Ergebnisse für Niedersachsen mit denen für das übrige West- bzw. für Ostdeutschland und mit den übrigen EU-Ländern in den meisten Fällen ein Bild ähnlich wie für Niedersachsen, aber die Gruppen der Starter umfassen dabei in der Regel nur wenige Firmen, und die geschätzten Koeffizienten sind sehr häufig statistisch insignifikant, so dass ein quantitativer Vergleich nicht möglich ist.
The paper demonstrates how the E–stability principle introduced by Evans and Honkapohja can be applied to models with heterogeneous and private information in order to assess the stability of rational expectations equilibria under learning. The paper extends already known stability results for the Grossman and Stiglitz model to a more general case with many differentially informed agents and to the case where information is endogenously acquired by optimizing agents. In both cases it turns out that the rational expectations equilibrium of the model is inherently E-stable and thus locally stable under recursive least squares learning.
