The rural mobilization gap in a U.S. place-based tax credit: Intermediary selection versus market structure in the New Markets Tax Credit

Latest version: August 2026

Pooled across intermediaries, rural New Markets Tax Credit projects carry less additional capital per dollar of subsidized investment than urban projects (−0.262); within the same Community Development Entity the gap is −0.047 (95% CI −0.245 to +0.152; median −0.001), and 86% of the explained movement is associated with which CDEs originate the deals.
