AbstractIn this paper we summarize recent research on the effects of European regional policy. Results point to a positive effect of this policy on average. One Euro spent even tends to generate more than one Euro in return in terms of GDP. However, the response varies drastically across recipient regions. First of all, there is evidence of existence of an optimum funding ratio (funds allocated relative to recipient GDP) where one Euro invested generates one Euro of return. About 36 percent of the regions receive higher funding than that, where one Euro generates less than one Euro of return (and, eventually, no return at all). Second, there is evidence of a bigger return on investment in regions with higher absorptive capacity level - measured by human capital endowments and the quality of recipient institutions. Insufficient levels of absorptive capacity lead to a wash of the Union’s transfers. About 70 percent of the regions exhibit such an insufficient level of absorptive capacity.
