Combining Experimental and Structural Methods

What happens when researchers combine experimental randomization with structural modeling? This video explores a recent school voucher study in India that demonstrates why the "reduced form vs. structural" debate misses the point entirely. In this final installment of our structural econometrics mini-series, we examine how researchers used a two-stage randomized experiment in rural Andhra Pradesh to estimate the true welfare benefits of school choice. The twist? Their initial structural model failed to predict voucher take-up rates. But the good news is that this shortcoming led to crucial discoveries about household search behavior and school supply responses.
