This study is the first empirical analysis to investigate the relationship between the investment behaviour of firms resident in Germany and the empirically determined marginal tax rates developed by John R. Graham. It is based on the Bundesbank's corporate balance sheet statistics for the period 1971-2002. In an autoregressive distributed lag model, the marginal tax rate is shown to be significant, with an elasticity of between 0.1 and 0.2. An error correction model does not produce any plausible results for the marginal tax rate. Graham's marginal tax rates are a complement to the methods typically used to determine the effective marginal tax rates and effective average tax rates.

Die Unternehmensbesteuerung ist eines der Instrumentarien das im Wettbewerb um den mobilen Faktor Kapital von den Industriestaaten eingesetzt wird. Hinsichtlich der wissenschaftlichen Forschung, die den Zusammenhang zwischen der Unternehmensbesteuerung und dem unternehmerischen Kapitalstock untersucht, ist mittlerweile eine beträchtliche Zahl von Literatur entstanden. Aus der vorhandenen Literatur sind jedoch zwei Schwächen zu erkennen. Erstens basieren viele der empirischen Analysen auf makroökonomischen Zeitreihendaten und zweitens finden vor allem Reduzierte-Form-Modelle Anwendung. Die vorliegende Dissertation gliedert sich in die Reihe empirischer Arbeiten unter Verwendung von Mikrodaten ein, die Aspekte der Unternehmensbesteuerung untersuchen. Die Arbeiten liefern einen Beitrag zum tieferen Verständnis aus den Teilbereichen der Finanzierunkstruktur, der gemeinsamen Bemessungsgrundlage sowie der Messung der marginalen Steuerbelastung. Dabei konzentrieren sich die Analysen auf die Aktivitäten deutscher Unternehmen im In- und Ausland sowie ausländischer Unternehmen in Deutschland. Grundlage der empirischen Untersuchungen sind vor allem vertrauliche Mikrodaten der Deutschen Bundesbank. Im Rahmen der deskriptiven und multivariaten Analyse werden Hinweise für den Zusammenhang zwischen der Besteuerung und dem unternehmerischen verhalten nachgewiesen. Damit dienen die Resultate auch als Diskussionsgrundlage für die Ausgestaltung künftiger Steuerpolitik in Deutschland und der EU. ; Corporate taxation is an instrument in the competition on the mobile factor capital which industrial countries using. Regarding the research, which examines the nexus between the corporate taxation and the firm's capital stock, meanwhile a considerable number of literatures developed. From the existing literature however two weaknesses are to be recognised. First of all many of the empirical analyses based on macro-economic time series data and secondly typically reduced from models were used. The present dissertation is integrated into the number of empirical work using micro data sets, which aspects of the corporate taxation examine. The analysis provides a contribution to the deeper understanding of the financial structure, the common tax base as well as the measurement of the marginal tax burden. The analyses concentrate on the activities of German companies (domestic and foreign direct investment) as well as foreign companies in Germany. The empirical investigations based mostly on confidential micro data sets of the German Central Bank. The descriptive and multivariate analysis show some hints for the nexus between corporate taxation and firm's behaviour. All results provide a discussion basis for the tax policy in Germany and the EU.

This paper analyses the effects of introducing a common EU tax base with formula apportionment on the size of the EU wide tax base and on the distribution of the tax base between the EU member countries. We use a combined dataset of Deutsche Bundesbank's Foreign Direct Investment data (MiDi) and corporate balance sheet data (Ustan and Hoppenstedt) for the tax base estimations. The data is used to construct i) a separate accounting and ii) a formula apportionment tax base for the firms in the sample. Our results suggest that due to border crossing loss-offset, the EU wide corporate tax base represented by our data sample shrinks significantly. Smaller countries which are usually considered to attract book profits under the current system, i.e. Ireland and the Netherlands, tend to lose a larger part of their tax base than larger countries like Germany, Italy, France or Great Britain. However, these results should be evaluated in the light of the limitations of the data used in this study since our analysis is based on German FDI data only. Furthermore, the calculations do not take into account behavioural responses of companies caused by such a system change.

In the paper we simulate a revenue-neutral cut in the social security contribution rate using five different types of macro- / microeconomic models, namely two models based on time-series data where the labour market is modelled basically demand oriented, two models of the class of computable equilibrium models which are supply oriented and finally a firm specific model for international tax burden comparisons. Our primary interest is in the employment effects the models predict due to the cut in the contribution rate. It turns out that qualitatively all models considered predict an increase in employment three years after the cut. But the employment effects differ considerably in magnitude, which follows immediately from the different behavioral assumptions underlying the different models.

Zu diesem Zweck werden fünf unterschiedliche ökonomische Modelle verwendet, namentlich zwei Modelle, die auf Zeitreihendaten aufbauen und in denen der Arbeitsmarkt überwiegend von der Nachfrageseite dominiert wird, zwei Modelle aus der Klasse der computable equilibrium models, die typischerweise angebotsorientiert sind, und ein mikroökonomisches, firmenspezifisches Steuerbelastungsvergleichsmodell. Alle Simulationsergebnisse der Modelle weisen auf einen, wenngleich teilweise kleinen, positiven Beschäftigungseffekt hin, der sich allerdings beträchtlich in seiner Größenordnung unterscheidet. Dies ist eine unmittelbare Folge aus den unterschiedlichen Verhaltensannahmen, die den einzelnen Modellen unterliegen.
