The approach
 Counterfactual framework -> Q: what would have
happened in the absence of the intervention?
 Quasi-experimental approach was chosen.
 Control group was selected from unsuccessful
applicants.
 Method used to reduce the selection bias:
Propensity Score Matching.
Data sets used in the evaluation
 PARP data sets (databases of all applicants, with
employment +9);
 19 covariates were controlled, such as: age,
revenues, size, legal form, assets, the use of
other subsidies, etc.
 Central Statistical Office data sets (Report on
revenues, costs and financial results and the cost
of fixed assets);
 31 outcome variables were estimated, such as:
net revenues from sales, employment,
expenditures, profits, etc.
