Dating apps and marriage rates
利用谷歌搜索强度作为Tinder扩散的代理变量，结合当前人口调查数据，发现Tinder对整体结婚率无显著影响，但提高了离婚或分居率，尤其在男性过剩和薄弱的婚恋市场中更明显。
We estimate how the diffusion of the dating app Tinder affected marriage outcomes in the United States. Using Google search intensity for “Tinder” as a proxy for platform exposure and individual-level data from the Current Population Survey, we estimate event-study specifications for adults aged 21–35. We find no effect on overall marriage rates or the timing of first marriage. However, Tinder exposure is associated with higher divorce or separation rates, particularly at younger ages. Marriage effects emerge in male-heavy and thin dating markets, suggesting that dating apps primarily ease matching frictions rather than increasing aggregate marriage formation.
