We generalize the growth-of-firm literature by linking alternative metrics of size via a Copula approach. We look at the result of the fitted Copula and justify the metric we base our analysis upon. We employ the Amadeus dataset and investigate the growth dynamics of the European pharmaceutical...

Fixed effects estimators in nonlinear panel models with fixed and short time series length T usually suffer from inconsistency because of the incidental parameters problem first noted by Neyman and Scott (1948). Moreover, even if T grows but at a rate not faster than the cross sectional sample...
