Can Internal Migration Foster the Convergence in Regional Fertility Rates? Evidence from 19th Century France
利用19世纪法国铁路建设带来的交通成本外生变化，构建十年期双边迁移矩阵，发现内部迁移通过传播低生育行为的信息，推动了各省份生育率的趋同。
This article offers an explanation for the convergence of fertility rates across French départements in the second half of the nineteenth century that emphasises the diffusion of information through internal migration. It tests how migration affected fertility by building a decennial bilateral migration matrix between French départements for 1861–1911. The identification strategy uses exogenous variation in transportation costs resulting from the construction of railways. The results suggest that the convergence towards low birth rates can be explained by the diffusion of cultural and economic information pertaining to low‐fertility behaviour by migrants, especially by migrants to and from Paris.
