We study debt and equity valuation when investors have private information and may exhibit differences of opinion. Our model generates several predictions that are consistent with empirical evidence but difficult to reconcile with traditional models. Belief dispersion relates to expected equity and debt returns in opposite directions. Similarly, expected debt (equity) returns typically increase (decrease) with default risk, though these relationships reverse for firms close to bankruptcy. Firms’ capital structures affect their valuations even without classical capital structure frictions (e.g., tax shields, distress costs) – when liquidity is higher in the equity than in the debt market, leverage can raise firm value.

We model the “feedback effect” of a firm's stock price on investment in projects exposed to a systematic risk factor, like climate risk. The stock price reflects information about both the project's cash flows and its discount rate. A cash‐flow‐maximizing manager treats discount rate fluctuations as “noise,” but a price‐maximizing manager interprets such variation as information about the project's net present value. This difference qualitatively changes how investment behavior varies with the project's risk exposure. Moreover, traditional objectives (e.g., cash flow or price maximization) need not maximize welfare because they do not correctly account for hedging and risk‐sharing benefits of investment.

While researchers and practitioners alike estimate firms' exposures to systematic risk factors, the disclosure literature typically assumes that exposures are common knowledge. We develop a model where the firm's exposure to a factor is unknown, and analyze the effects of factor-exposure uncertainty on share price and the effects of disclosure about the exposure. We find that: (1) factor-exposure uncertainty introduces skewness and excess kurtosis in the cash flow distribution relative to the commonly used normal distribution; (2) risk-factor disclosure affects all moments of that distribution; and (3) the pricing of higher moments affects the price response of disclosure and the incentives to disclose. For example, factor-exposure uncertainty may actually increase price when the uncertainty implies positive skewness in the cash flow distribution. Hence, a reduction in uncertainty through disclosure may increase cost of capital. We also extend our model to multiple firms and show that factor-exposure uncertainty manifests as uncertainty about a firm's CAPM beta.

We study the impact of asymmetric (i.e., conservative or aggressive) disclosure on a firm’s price in the classic setting in which its stock is traded by risk-averse investors and noise or liquidity traders. We show that asymmetric accounting policies alter the relative risk faced by investors when they short versus long, which causes market liquidity to differ for positive versus negative demand shocks. As a result, accounting conservatism raises firms’ valuations and lowers their expected returns. We further demonstrate that the relationship between accounting informativeness and expected returns depends upon the skewness of investors’ prior beliefs. Finally, we find that a firm that can commit to an accounting policy can tailor this policy to benefit from noise trade and foster overvaluation.
