Implications of the State Aid Modernisation for the Assessment of Large Investment Projects

Hans W. FriederiszickEStAL - Issue: 1/2013 - pp. 46-60., January 2013

The Regional Aid Guidelines foresee specific screens for an in-depth assessment of Large Investment Projects (LIPs): an in-depth assessment is initiated if the market share of the aid beneficiary is above 25% or the investment results in a capacity expansion above 5% in a declining market. It is currently being discussed within the broader State Aid Modernization package and also due to a recent court ruling on the case Propapier whether these market screens should stay as they are. Based on a dataset of all LIP cases notified under the 2006 Regional Aid Guidelines, we evaluate those market screens and find that the screens do have the power to identify problematic cases – cases with a below average expected aid effectiveness and aid measures targeting specific industries. We also find, however, that the market screens are affected by a severe implementation problem and, hence, do not help to shorten phase I investigations. From a conceptual perspective, they are also not capable of identifying some of the potentially most problematic regional State aid cases. Policy options are discussed.
