Marshallian and Jacobian externalities in creative industries: Evidence from Chile
研究智利创意产业的专业化是否带来马歇尔或雅各布斯外部性，发现创意部门专业化促进自身销售和企业数量，但对其他部门无显著溢出效应。
Most papers on creative industries ask whether they are a source of Marshallian or Jacobian effects, inasmuch as a stronger creative sector is a direction of diversification that could have positive spillovers onto the rest of the economy. While most works have focused on developed economies, I contribute evidence from a middle-income Latin American country and study both creative occupations and creative sectors. I find that specialisation in creative sectors is associated with higher sales and a larger number of firms in those sectors, albeit at a decreasing rate. A similar relationship is found between specialisation in creative occupations and the income of those workers. I find no evidence of effects of creative specialisation on other sectors.
