This document summarizes a model of financing risky research and development projects under conditions of asymmetric information. It examines how different types of informational imbalances impact equilibrium in venture capital markets. These asymmetries can involve a project's innate quality or the effort exerted by inventors and financiers. The model studies equilibrium screening and funding of projects when self-selection contracts are the only mechanism available, specifying investment levels and distribution of returns. Informational asymmetry about project quality and entrepreneur actions reduces inventor utility but increases effort and success rates, while asymmetry about financier actions further decreases inventor utility and leads to sub-optimal effort levels.
