Abstract: Policy evaluation is a central question in empirical economic studies, but economists mostly work with observational data in view of the limited opportunities to carry out controlled experiments. The lack of genuine control groups motivates the panel data approach (Hsiao, Ching and Wan, 2012) to exploit the correlation between cross-sectional units in a panel data to construct the counterfactual. The choice of cross-sectional units, a key step in implementing their method, is not addressed in the case of many potential controls. We propose to use the forward selection for control-unit selection. We show that such a choice is asymptotically valid even if the number of potential controls grows, in the limit, faster than the time dimension. Both in theory and in practice, we open the possibility for applying the panel data approach to big data environment.
