This thesis uses the tools of applied econometrics to study the impact of economic incentives on household welfare and decision-making and health and risk behaviors in the U.S. and in developing countries.

The first chapter studies the impact of increasing access to credit among low-income households in Mexico. Banco Azteca opened 815 branches simultaneously in a popular retail chain store, Grupo Elektra, in October 2002. Although access to credit increased, affected households experience negative or null impacts on consumption expenditures and asset holdings. I argue that this because the bank encourages individual borrowers to use loans for consumption use at Grupo Elektra. This research demonstrates that the package within which the loan is offered is as important as the loan itself.

The second chapter focuses on the impact of job loss to dual-earner married couples on household fertility decisions, drawing upon the recent experience of job loss during the Great Recession. I build two datasets, covering the years 2003-2011 that match job losses due to mass layoff events to fertility rates among married couples at the county-year and state-quarter level. I find that job losses have a negative impact on fertility. However, areas with more dual-earner households experience lesser declines in fertility rates in response to job losses, suggesting that dual-earner households are more likely to substitute toward child-rearing in response to job loss compared to single-earner households.

The third chapter, joint with Lisa Cameron and Manisha Shah, exploits the criminalization of sex work in a district in East Java, Indonesia, and utilizes a unique dataset comprised of the first panel data on female sex workers and the first data on clients to estimate the impact of criminalizing sex work on health and risk behaviors. Criminalization increased STI rates among female sex workers by 58 percent. The main mechanism driving this increase is decreased access to condoms and increased non-condom use during commercial sex transactions. We rule out other mechanisms, such as increased transactions or clients per sex worker. This research presents new evidence that criminalizing sex work can put an already vulnerable population in a more precarious situation.

    Nearly 5.6 million Syrian refugees were displaced by the country’s civil war, of which 50% percent are children. Given the heightened risks of psychological distress for this population it is critical to efficiently and accurately assess well-being for this population for intervention. A digital analysis of features in children’s drawings potentially represents a rapid, cost-effective, and non-invasive method for collecting individual and aggregate data on children’s mental health. Using data collected from free drawings and self-portraits from over 2,500 Syrian refugee children in Jordan across two distinct datasets, we use regression and Lasso machine-learning techniques to understand the relationship between exposure to violence and different measures of psychological trauma. Our results suggest that individual drawing characteristics are strongly correlated with validated measures of psychological trauma and past exposure to violence, with child mental health declining with increased exposure to violence and improving with resettlement in host communities. These results serve as a proof-of-concept for the potential use of children’s drawings as a diagnostic tool in human crisis settings.
