α: calibrated so average coauthorship-adjusted count equals average raw count
We study business creation subsidies in a general equilibrium model where firms are financially constrained upon entry and borrow competitively by issuing long-term debt. If paid out before business formation (ex ante), the subsidy reduces start-ups’ debt and bankruptcy rates; if paid out as a refund of expenditures (ex post), it reduces equity rather than debt, raising bankruptcies among both new and existing firms. In a model calibrated to Southern Italy, the optimal subsidy is paid entirely ex ante, raising welfare by 2% of consumption. If paid ex post, the same subsidy would result in welfare losses.
