Equity Market, Financing, and Investment Missaka Warusawitharana Toni M. Whited North America meetings of the Econometric Society, June 2014
Question Do managers react to perceived equity mispricing? How do managers react?
Heavily researched but hard question One cannot observe mispricing. Reactions to mispricing are endogenous. Two exclusion restrictions. Literature lacks a quantitative assessment.
Alternative approach Estimate a dynamic model of investment and financing. Deviations of intrinsic from market value. Issuances and repurchases when equity is over or under valued. Model parameters dictate The magnitude of these reactions The uses and sources of these funds
Results Model fits a broad set of data moments: large heterogeneous samples across industries shocks: statistically significant. Equity issuers time the market, but proceeds primarily go in and out of net saving. Timing adds a small amount of value for long term shareholders.

Dilution Mispricing affects dilution (or concentration) of the controlling shareholders block stake. V V + E = ψ(v D(1 τ)) ψ(v D(1 τ)) + E Market participants draw inference on the size of misvaluation from the transaction size, with a concave price impact function.

Model estimation Estimate some parameters directly by calculating averages: r f, δ, τ c For the rest of the parameters use SMM (Ingram and Lee, 1991). Draw from (z, ψ) Compute v (c, ψ, z) and (c, e, i) = h (c, ψ, z) Repeat Simulated data Interesting moments Real data Interesting moments
Identification Use moments that vary when the underlying structural parameters vary. Do not cherry-pick. Use many moments. Identify the variance and autocorrelation of misvaluation shocks. The moments involving profits are only affected by the profitability shock parameters.

Conclusion Use structural estimation to infer the effects of equity misvaluation on corporate policies. The standard deviation of misvaluation shocks is significant. Firms issue equity in response to overvaluation and repurchase equity in response to undervaluation. Proceeds mostly funneled into cash. does help ease the effect of costly external finance on investment.
