Emoting with their feet: Bohemian attraction to creative milieu
检验创意阶层理论，通过建模1990年县级艺术就业份额，用其残差解释1990-2000年经济活力差异，发现吸引艺术家的创意环境能提升地方经济活力。
Creative class theory posits that creative people are attracted to places most conducive to creative activity. The association of the share of employment in the arts with various indicators of economic dynamism provides plausible support for this conjecture. We explicitly test this conjecture by modeling the 1990 share of employment in the arts at the county level, and then use the residual from this regression to explain differences in various measures of economic dynamism between 1990 and 2000. Our results support the hypothesis that an unobserved creative milieu that attracts artists increases local economic dynamism.
