Multivariate Tobit models are estimated using German cross?sectional data to test whether strategic complementarities exist between expenditures in four different types of ICT?components. If two ICT?components are complements, they are correlated (provided that agents act rationally)....

This study analyses relative sectoral specialisation of EU regions on the basis of investment and employment patterns. Controlling for heteroscedasticity and potential endogeneity in the econometric analysis, we find that relative specialisation in manufacturing sectors is higher in central...

Owners of private companies are often highly underdiversified which exposes them to idiosyncratic risk. We investigate the consequences of underdiversification at the company level. Information on US companies and their owners is obtained from the Survey of Consumer Finances and the Survey of...

Kapitalmarktorientierte Unternehmen in Deutschland orientieren sich in zunehmendem Maße an der Konzernsteuerquote. Diese unterscheidet sich in wesentlichen Aspekten von den in der Forschung gängigen Maßen der effektiven Besteuerung, die auf dem neoklassischen Investitionsmodell basieren. Dies...

This research investigates the hypothesis that publicly funded scientific research complements private R&D investment in the pharmaceutical industry. New microlevel data on public research investment by the U.S. National Institutes of Health allow measures of basic and clinical research in seven...

In this paper the outlier robust GMM panel data estimator recently proposed by Lucas, van Dijk, and Kloek (1994)is applied to an Euler equation model of firm investment behaviour with imperfectly competitive product markets for a small panel of German nonfinancial stock companies. Plots for...

Capital mobility is helpful to cope with the loss of adjustment instruments in EMU. High capital mobility in the sense of Feldstein and Horioka (FH) can limit the negative consequences of shocks affecting the saving capacity of an economy in the Eurozone. It is the aim of this paper to assess...

The macroeconomic development in West Germany in the aftermath of unification was characterized by a boom period in 1990/1991, a deep recession in 1992/1993 and a slow recovery since then. In East Germany, in contrast, unification induced a breakdown of production and employment followed by a...

This paper discusses theoretically the different incentives of managers versus firm owners to invest in innovative activities. There are opposing effects concerning R&D intensity in the manager-controlled firm. Our study on the determinants of R&D intensity presents empirical results concerning...

This study analyses relative sectoral investment patterns in EU regions. In an exploratory spatial data analysis, spatial clusters of high relative investments can be identified for some sectors. In the econometric analysis, we control for heteroscedasticity and potential endogeneity and find...
