Introduction Task in this research project: Explore to what extent publicly available beneficiary data of European Cohesion Policy can be used for a quantitative study of policy impacts at the firm-level Focus: innovation activities of firms Requirements: Linking beneficiary data to firm-level information Amadeus Database Patent database Other resources containing data about innovation activities at the firm level Obtain control group of non-funded firms
Challenge Beneficiary lists typically only include –Recipient name –Project title –Year of funding approval –Approved amount of funding Recipient names have to be searched in other databases using text field algorithms Potential hits have to be manually checked –For each study two text field searches necessary: –Recipients have to be identified in Amadeus database –Identified Recipients and control group (obtained from Amadeus) have to be searched in patent database or other related data source containing information on innovation activities
Countries examined Of 11 countries/regions investigated: Poland, Slovakia, Slovenia, Flanders, Wales and London were eliminated because of small numbers of projects in these regions/countries. Spain was eliminated as in the data we had available firm names were not included. FR data were tested, but was impossible to tell treatment date Only CZ and DE retained
Country case I: Czech Republic Recipient data: –26,075 projects –Time period: 2006 – 2011 –Total amount of 10,747,210,000 –Avg. amount per project 412,265 How many (different) firms? –unknown!!! Name list is searched in Amadeus (firm database) –contains 14,609 different firms
Country case I: Czech Republic Data: Total # of firms contained in Amadeus: 14,609 Total # of firms retained : 12,887 Methodology: Difference-in-difference Compare annual patent applications per firm in pre- treatment (1997-2003) and treatment phases (2008/9) 1,433 treated firms 11,454 control firms
Country case I: Czech Republic Patenting fell by 63% in controls, only 14% in treated Highly statistically significant (chi² =12.07, p<0.01) Understates impact, since some firms still in their pre- treatment phase (data lag) Patenting here is really a proxy for a wider range of innovative activities Next example has data for wide range of innovation activities…
Country case II: Germany Recipient data: –47,616 projects (out of those 33,201 in Eastern Germany) –Time period: 2006 – 2011 –Total amount of 9,060,653,000 –Avg. amount per project in Eastern (Western) Germany: 92,400 ( 415,923). Name list is searched in Mannheim Innovation Panel Outcome variables: –R&D investment (R&D intensity = R&D / Sales) –R&D employment divided by total employment –Total innovation investment / Sales –Investment into physical assets (relative to capital stock) –Innovation types
Link to the Mannheim Innovation Panel MIP = German part of the the CIS Annual survey; asks about 5,000 firms about the innovation activities We can link 5,606 different grants to the MIP. These correspond to 1,904 different firms. –Restrict time period to 2007-2010: We lose firms as they are in the MIP but not in the relevant years. –After removing observations with missing values in variables of interest, we can use a final sample of 623 supported firms. –Control group: 21,226 observations Estimator: Nearest Neighbor matching

Germany Robustness tests: Restrict sample to innovating companies –as purpose of project is not supported systematically: innovation vs. something else –Main results reported earlier hold BUT: Once we control for subsidies received from German Federal Government all positive effects reduce somewhat in terms of magnitude and also statistical significance reduces slightly. Cohesion Fund reciepients are also more likely to receive other subsidies!!!
Germany Robustness test: does the size of the grant matter?
Lessons learned Reporting standards should be improved. Otherwise a quantitative evaluation lacks credibility or produces no results because of noisy data. What should be reported at the minimum? –Funding start and end date in addition to amount –Type of recipient (firm vs. other) –Purpose of grant –Recipient name AND location –All in database compatible formats And…. –If possible, historical data should be stored centrally, e.g. by EC. –Longer time lag between evaluation and program completion should be applied.
