The paper provides a statistically robust evaluation of the impact of state aid on capital accumulation in subsidized firms. The analysis considers subsidies allocated to the southern Italian regions over the period 1996-2004 under the regional policy, Law 488/1992. We apply an MDID estimator, taking selection on observables and non observables into account. Results evidence a higher growth in output, employment and fixed assets in subsidized firms but a lesser increase in Total Factor Productivity than in unsubsidized firms. The negative impact on long term productivity and growth reduces the positive temporary effects of regional subsidies.
