Milakovic, Alfarano and Lux (2010) have identified a small core of directors who are both highly central to the entire network of German corporate boards as well as closely connected among themselves. While their analysis has been based on data for the management and supervisory boards of a...

We consider the current bipartite graph of German corporate boards and identify a small core of directors who are highly central in the entire network while being densely connected among themselves. To identify the core, we compare the actual number of board memberships to a random benchmark,...

In contrast to the predictions of conventional economic theory, it is well documented that similar workers receive wages positively correlated with the size of the firm employing them. To explain these findings the author augments the Waldman framework (Job Assignments, Signaling, and...

Although there is a large and rapidly growing literature on the determinants of regional variation in new firm formation, relatively little is known about the interrelation between the characteristics of start-up firms and urban structure. It is only recently that scholars of urban economics...

We develop an endogenous growth model which is focussed on entrepreneurial skills and their impact on growth and convergence. Our work is closely related to the model by Acemoglu et al. (2006) but extends their analysis in some important respects. Entrepreneurs in our model dispose of two...

Relationship banking involves the provision of financial services by an intermediary that a) invests in obtaining customer-specific information, often proprietary in nature; and b) evaluates the profitability of these investments through multiple interactions with the same customer over time...

Whereas microeconomic studies point to pronounced downward rigidity of nominal wages in the US economy, the standard Phillips curve neglects such a feature. Using a stochastic frontier model we find macroeconomic evidence of a strictly nonnegative error in an otherwise standard Phillips curve in...

Over the past two decades, technological progress in the United States has been biased towards skilled labor. What does this imply for business cycles? We construct a quarterly skill premium from the CPS and use it to identify skill-biased technology shocks in a VAR with long-run restrictions....

Many labor market models use both idiosyncratic productivity and a vacancy free entry condition. This paper shows that these two features combined generate an equilibrium comovement between matches on the one hand and unemployment and vacancies on the other hand, which is observationally...

We address the question of whether foreign aid helps attract foreign direct investment (FDI). This could be achieved if well targeted aid removed critical impediments to higher FDI inflows. In particular, test the hypothesis that aid for education is an effective means to increase FDI flows to...
