We model an economy where it is beneficial for high-type organizations to collaborate with other high types, and where this assortative-matching pattern allows informed financiers to provide inexpensive funds to partner companies of their high-type ventures. The expected funding benefit associated with finding high-type partners increases in the supply of informed capital, which creates an additional incentive for high types to search. Our main result is that, in such a setting, a critical mass of informed capital is sometimes required for an efficient equilibrium to obtain. We provide a novel channel for how the financial sector can impact real outcomes, specifically by affecting matching patterns.
