“…Wright, Gilligan and Amess, 2009). These studies range from macro-economic panel estimations (e.g., Romain and van Pottelsberghe, 2004), to estimations mainly based on sectoral data (e.g., Kortum und Lerner, 2000;Tykvová, 2000;Hirukawa and Ueda, 2008a,b) as well as to micro-econometric analyses and paired sample tests (e.g., Hellmann andPuri, 2000, 2002;Belden, Keeley and Knapp, 2001;Botazzi and Da Rin, 2002;Engel, 2003;Engel and Keilbach, 2007;Sorensen, 2007;Lerner, Sorensen and Stromberg, 2008;Bloom, Sadun and van Reenen, 2009). This paper is part of the latter strand, which contrasts the development of individual firms backed by venture capital with a hypothetical 'counterfactual' observation based on the careful selection of a comparable control group.…”
