This thesis consists of two chapters. In Chapter 1, I studied the consumption inequalities between men and women, as well as boys and girls, within the households in Sierra Leone. Through a collective household model, I found that women on average experience lower levels of consumption than men, with the inequality concentrated in households that are large or consist of more women than men. Moreover, there is little evidence of overall consumption inequality by gender for children, while both boys and girls have very high poverty rates. In addition, I developed a new strategy for understanding who is perceived as a child vs. an adult in a household, which improved the estimation. In Chapter 2, I studied the associations between sugar-sweetened beverage (SSB) taxes and adolescent obesity in the US. I found that the taxes were associated with a lower body mass index and a lower probability of being overweight or obese. I found that SSBs and milk consumption had mediating roles, as tax increases were associated with decreases in SSB consumption and increases in milk consumption. Given the limited implementation and recent preemption of SSB taxes across the US, these results would help in understanding the potential benefits of implementing SSB taxes on a larger scale.
