Empirical evidence on the evolution of innovation networks within high-tech industries is still scant. We investigate network formation processes by analyzing the timing of firms to enter R&D cooperations, using data on laser source manufacturers in Germany, 1990-2010. Network measures are...

We estimate the relationship between changes in the body mass index (bmi) and wages or satisfaction, respectively, in a panel of German employees. In contrast to previous literature, the dynamic models indicate that there is an inverse u-shaped association between bmi and wages among young...

Decomposition of the goodness of fit to (groups of) regressor variables can be a useful diagnostic tool to quickly assess “relative importanceâ€. Owen and Shapley values, two closely related solutional concepts in cooperative game theory, provide unique solutions to the decomposition...

We estimate the effect of changes in the body mass index on wages and satisfaction in a panel of German employees. Dynamic models indicate that satisfaction with life in general and with health are responsive to weight changes, but wages and satisfaction with work are not. These results mainly...
