In this paper we show that the recent model by Duranton (AER, 2007) performs remarkablywell in replicating the city size distribution of West Germany, much better than the simplerank-size rule known as Zipf´s law. The main mechanism of this theoretical framework is thechurning of industries...

Audretsch and Fritsch (2002) proposed two explanations for the mixed evidenceregarding the relationship between new firm formation and regional development. Firstly,they found evidence for the existence of long time lags needed before the main effects of newfirm formation on employment change...
