May 2018Selection versus Talent Effects on Firm Value
with Harrison Hong: w24672
Measuring the value of labor-market hires for stock prices, be it underwriters when firms go public (IPOs) or chief executive officers (CEOs), is difficult due to selection. Opaque firms with higher costs of capital benefit more from prestigious underwriters, while productive firms benefit more from talented CEOs. Using assignment models, we show that the importance of talent (or agent heterogeneity) relative to selection (or firm heterogeneity) is measured by wage increases across agents of different compensation ranks divided by changes in output across their firms. The median of this ratio is 0.5% for underwriters and 2% for CEOs.

January 2017Assignment of Stock Market Coverage
with Harrison Hong: w23115
Price efficiency plays an important role in financial markets. Firms influence it, particularly when they issue public equity. They can hire a reputable underwriter with a star analyst to generate public signals about profits, thereby reducing uncertainty and increasing valuations. We develop an assignment model of this labor market. The value of a match between firms, that differ in multiple dimensions, and agents, that differ in precision, is endogenously generated from a stock-market equilibrium. We characterize the multidimensional-to-one assignment and obtain predictions. Extensions allow firms to value efficiency for other reasons and apply to other labor markets like media-or-investor relations.
