Title: "A Difference-in-Differences Approach Using Mixed-Integer Programming Matching"

Abstract: Differences-in-Differences (DD) is a commonly-used approach in policy evaluation for identifying the impact of an intervention or treatment. Under a parallel trend assumption, we can recover a causal effect by comparing the difference in outcomes between a treatment and a control group, both before and after an intervention was set in place. However, time-varying confounders often break the identifying assumption, biasing our estimates. In this presentation, I identify the different contexts in which matching can help reduce such biases, and show how balancing covariates directly can yield better results for solving these issues. I also show how this method can be applied both for panel and repeated cross-sectional data. I illustrate these results with simulations and a case study of the impact of a new voucher scheme on socioeconomic segregation in Chile.
