Diffusion of Reproductive Health Behavior through International Migration: Effects on Origin-Country Fertility
研究菲律宾移民接触目的地国生殖健康政策如何降低原籍社区生育率，发现现代避孕措施采用增加是主因，政策可见性（如避孕广告）和行为规范起调节作用。
International migrants may facilitate the transmission of ideas across countries. We examine the impact of migrant exposure to reproductive health policies on origin-country fertility in the Philippines. We exploit temporal variation in destination-country reproductive health policies combined with spatial variation across Philippine provinces in their migration intensity and historical composition of migrant destinations. Migrant exposure to more liberalized reproductive health policies reduces origin-community fertility. This reduction is driven by increased adoption of modern contraceptives. Visible policy changes, such as commercial advertising of contraceptives, lead to this change in behavior. Firmly established family planning values moderate the fertility response.
