This dissertation is composed of three essays that explore agriculture and demography issues in developing countries. The first two chapters investigate smallholders' agricultural technology adoption decisions in Mozambique and Tanzania, respectively. The third chapter examines the impacts of skewed sex ratios in Paraguay. All essays are motivated by the analysis of how individuals' behaviors and decisions are affected by various factors, such as personal characteristics, exogenous treatments and conflicts, and culture norms. To address these topics, both data collected through a field experiment and nationally representative surveys are used, while different methods are applied-experiment, structural model, and reduced-form analysis.Despite the importance of agriculture sector and the availability of technologies that enhance yields, smallholders in Sub-Saharan Africa persistently use traditional farming methods and face low agricultural productivity. In the first chapter, which is coauthored with Florence Kondylis and Valerie Mueller, we investigate which channels can diffuse and boost adoption of productive farming practices. Specifically, we conduct a large-scale randomized field experiment in Mozambique to measure the impact of augmenting the contact farmer (CF) model with a direct CF training on the diffusion of a new technology.Moving forward with the information transmission and promotion channel research, I examine the rationale behind small-scale farmers' adoption decisions in my second chapter. There is a well-known technology adoption puzzle: Why do African farmers not adopt modern technologies that economists believe should provide higher returns on average, for example fertilizer, and at the same time why do African farmers adopt traditional technologies that economists consider unprofitable, for example intercropping? I build a structural model, estimate it with data from Tanzania, and offer an explanation to this puzzle.The third chapter, which is coauthored with Jennifer Alix-Garcia, Laura Schechter, and Felipe Valencia Caicedo, explores another central theme in the field of development economics, gender. Using the event of the War of the Triple Alliance, we examine both the short-term and the long-term impacts of a temporary variation in sex ratios on the economies, such as the marriage market and labor market performances.
