Venture Capital and the Macroeconomy

I develop a model of venture capital (VC) intermediation that quantitatively explains central empirical facts about VC activity and can evaluate its macroeconomic relevance. The impact of VC-backed innovations is significantly larger than suggested by observed aggregate venture exit valuations, even after accounting for large exposures to systematic and uninsurable idiosyncratic risks. The risk properties of venture capital play a quantitatively important role in both explaining empirical regularities and shaping the value of ventures’ contributions to economic growth. The model is analytically tractable and yields exact solutions, despite the presence of matching frictions, imperfect risk sharing, and endogenous growth.
