NBER Working Papers by Frank Rothaermel

We present a theoretical model of startup signaling with multiple signals and potential dierences in external investor preferences. For a novel sample of technology incubator startups, we empirically examine the use of patents and founder, friends, and family (FFF) money as such signals, nding that they are jointly endogenous to venture capital and business angel investment in the startups. For this sample, venture capitalists appear to value patents more highly than FFF money, while the reverse is true for business angels. Moreover, the impact of patents on venture capitalists is larger than the impact of FFF money on business angels.
