This paper takes up a phenomenon in European geographical development: the simultaneity of regional economic convergence on the one hand and the continued spatial concentration of economic activities on the other. Overall, the disparities in productivity and income between regions in the...

After 20 years of transition from an economy integrated in an exchange scheme of planned economies towards an open market economy based on the ideas of competition, we ask whether East German firms succeeded in finding their place in the international division of labour. We concentrate on the...

East German wages have been below the West German wage level since unification. Moreover, the East-West wage gap implied by the contractual wages specified in collective wage agreements is drifting ever further apart from the wage gap in terms of effective wages. This paper looks at the role of...

Financial theory creates a puzzle. Some authors argue that high-risk entrepreneurs choose debt contracts instead of equity contracts since risky but high returns are of relatively more value for a loan-financed firm. On the contrary, authors who focus explicitly on start-up finance predict that...

We develop a composite indicator measuring the performance of national innovation systems. The indicator takes into account both hard factors that are quantifiable (such as R&D spending, number of patents) and soft factors like the assessment of preconditions for innovation by managers. We apply...

Using panel data on European regions and applying Analysis of Covariance, our study provides an empirical assessment of the relative importance of national, regional and spatial factors for explaining variations of productivity. Our analysis shows that initial economic conditions or...

Trade theory and economic geography suggest that the removal of trade barriers is likely to bring about more economic specialisation and potentially more diverse development paths between countries and regions. Thus, the deepening and extending European integration should be accompanied by an...

It is argued that the observed return rates on capital at firm-level have an upward bias if firms are producing with unobserved intangible capital. Using EUKLEED, a comprehensive firm level data base for Germany, this theoretical preposition is proved empirically. Furthermore, making unobserved...

This paper analyzes the effect of agglomeration economies on firms' total factor productivity. We propose the use of a control function approach to overcome the econometric issue inherent to the two-stage approach commonly used in the literature. Estimations are conducted separately for four...
