The Social Value of Financial Expertise

Abstract

I study expertise acquisition in a model of trading under asymmetric information. I propose and implement a method to measure r, the ratio of the marginal social value to the marginal private value of expertise. This can be decomposed into three sufficient statistics: traders’ average profits, the fraction of bad assets among traded assets and the elasticity of good assets traded with respect to capital inflows. For junk bond underwriting I measure r = 0.18 and for venture capital I measure r = 0.73. In both cases this is less than one, which implies that marginal investments in expertise destroy surplus.
