I introduce two dimensions of uncertainty, about the upside and the downside of an asset, in a model of asset valuation under asymmetric information. This justifies capital structures with equity and risky debt for information revelation purposes. However, a capital structure with only one information-sensitive security, equity, can be optimal when investors are less informed about the dimension that matters more for valuation. This is relevant for innovative firms with a large upside subject to strong information asymmetries, which often have abnormally low leverage, and for firms at an intermediate stage of their life cycle that do not issue risky debt.

We consider a model of chief executive officer (CEO) selection, dismissal, and retention. Firms with larger blockholder ownership monitor more; they get more information about CEO ability, which facilitates the dismissal of low-ability CEOs. These firms are matched with CEOs whose ability is more uncertain. For retention purposes, the compensation of these CEOs is more sensitive to firm value and relatively less sensitive to business conditions. Moreover, these CEOs receive lower salaries when CEO skills are sufficiently transferable. A diffusion of best monitoring practices increases competition for CEOs and raises CEO pay in all firms, including those with unchanged monitoring ability.
