An assessment of the application documents conducted by the Ifo Institute for Economic Research, of which I am President, found that the nearly 2,000 potential projects would cost a total of €1.3 trillion, with about €500 billion spent before the end of 2017. Some 53% of those costs correspond to public projects; 15% to public-private partnerships (PPPs); 21% to private projects; and just over 10% to projects that could not be classified.
