[We examine the predictive power of equilibrium dominance in experimental markets where firms with investment opportunities have an informational advantage over potential investors and are permitted to purchase a money-burning signal. Equilibrium dominance often fails to predict well when a Pareto-superior sequential equilibrium is also available. Instead, equilibrium selection appears to be related to the potential earnings of a more valuable firm that can signal its type successfully by defecting from the sequential equilibrium. Potential investors formulate their bids for firm equity based primarily on expectations formed adaptively in response to signaling choices made by firms.]

[This study investigates experimental financial markets in which firms possess more information than do potential investors. Firms were given opportunities to undertake positive net present value projects which they could either forgo or finance by selling equity. Auctions were conducted among the investors for the right to finance the projects. When the theoretical equilibrium was unique, theory predicted well. When theory permitted pooling, separation, and semiseparation, only the more efficient pooling equilibrium was observed. The domination of the pooling equilibrium was robust to different experimental experiences by participants. When available, signals were used by good firms to distinguish themselves from bad.]

Considerable research tackles the aggregate impact of debt financing. We show that equity is more important for firm growth than generally understood. A dollar of equity issuance is associated with an extra $0.93 of real assets, whereas a dollar of debt issuance is associated with an extra $0.14. Firms issue equity first, then increase real assets, and, finally, issue debt while repurchasing equity. We explain this sequence using a model in which debt is tax preferred relative to equity but is subject to limited commitment. We use the estimated model to evaluate how several government policies affect corporate growth.
