This paper compares and evaluates eleven proposals, which suggest policies and institutional arrangements to close the European investment gap. The differences between the proposals analyzed here are notable but the majority of them share a large common ground regarding size, financing, institutional set-up and areas to invest in. Most proposals want to mobilize between 100 and 300 bn€ p.a. of private capital by leveraging funds from either the EU or government budgets or the EIB or new public investment funds. They intend to channel this capital into projects with long-term benefits for Europe, primarily infrastructure and energy.
