Olivier Gergaud, Morgane Laouénan, Étienne Wasmer:

Last and not least, we find a positive correlation between the contemporaneous number of entrepreneurs and the urban growth of the city in which they are located the following decades. More strikingly, the same is also true for artists, with the contemporaneous number or share of artists positively affecting city growth over the next decades. In contrast, we find a zero or negative correlation between the contemporaneous share of “militaries, politicians and religious people” and urban growth in the following decades.
