- 요약This dissertation addresses three topics in agricultural economics and rural resilience with direct policy implications in low- and middle-income country contexts. Chapter 2 explores the impact of subsidized agricultural mechanization on labor employment. Implementing a shift-share instrumental variable design with web-scraped, administrative and survey data, I find no support for the hypothesis that agricultural mechanization pushes labor into non-agricultural sectors. Conversely, it attracts male labor back into agriculture and has the unintended consequence of reducing female labor force participation. Chapter 3 addresses the puzzle of the widely observed inverse relationship between farm size and productivity in low- and middle-income countries. We highlight the issues with ratio variables commonly used in this literature, showing that the inverse relationship may largely be an artifact due to model misspecification and publication bias and therefore challenging justifications for policies to keep farms "small and beautiful". Chapter 4 examines a potential threat to equity in a voluntary public pension system for the rural agrarian population. Combining individual fixed effects with instrumental variables selected by Lasso regression, I find no evidence of adverse selection that individuals with shorter longevity beliefs are less likely to enroll or contribute less, possibly due to particular elements in the program design and implementation.
