文献来源 We collect grant information on R D innovation grants. We collect local, state, and federal grant data using the Good Jobs First subsidy database. This database identifies grants and other assistance received by firms over the past thirty years. Firms can receive multiple grants, and we know the zip code where the grants originated. We match our grant data to the firm-level data using S P’s unique identifier (GVKEY), which is common in each sample. Subsidy Tracker (goodjobsfirst.org) Unsal, O., Houston, R. (2024).
