Combining rules and discretion in economic development policy: Evidence on the impacts of the California Competes Tax Credit
研究了加州竞争税收抵免（CCTC）对地方就业的影响，发现每激励一个工作岗位可带来近3个本地就业增长，且对非制造业和不同社会经济群体均有积极作用。
We evaluate the effects of one of a new generation of economic development programs, the California Competes Tax Credit (CCTC), on local job creation. Incorporating perceived best practices from previous initiatives, the CCTC combines explicit eligibility thresholds with some discretion on the part of program officials to select tax credit recipients. The structure and implementation of the program facilitates rigorous evaluation. We exploit detailed data on accepted and rejected applicants to the CCTC, including information on the scoring of applicants with regard to program goals as well as on funding decisions, together with restricted-access American Community Survey (ACS) data on local economic conditions. Using a difference-in-differences approach, we find that each CCTC-incentivized job in a census tract increases the number of individuals working in that tract by close to 3 – a significant local multiplier. Local multipliers are larger for non-manufacturing awards than for manufacturing awards. CCTC awards increase employment among workers across socioeconomic groups and in more- as well as less-advantaged neighborhoods, but have limited impact on residents of affected communities. We validate our empirical strategy and confirm our core results using an alternative dataset and recently developed difference-in-differences methods that correct for potential biases generated by variation in treatment timing and treatment effect heterogeneity.
