DETERMINANTS OF TECHNOLOGY ADOPTION: PEER EFFECTS IN MENSTRUAL CUP TAKE-UP
基于尼泊尔随机发放月经杯的数据，研究发现同伴接触显著提高使用率：每多一位有杯子的朋友，使用率提高18.6个百分点，且同伴主要帮助学习使用方法而非改变使用意愿。
We estimate the role of peer effects in technology adoption using data from a randomized distribution of menstrual cups in Nepal. Using individual randomization, we estimate causal effects of peer exposure on adoption. We find strong evidence of peer effects: two months after distribution, one additional friend with access to the menstrual cup increases usage by 18.6 percentage points. Using the fact that we observe both trial and usage of the product over time, we examine the mechanisms that drive peer effects. We show evidence that peers impact learning how to use the technology, but find less evidence that peers impact an individual desire to use the menstrual cup.
