Abstract
This paper proposes a historically-grounded mechanism-design model of corporate finance, with two-side risk aversion under limited contract enforceability, where (inside) equity held by entrepreneurs, debt and (outside) equity coexist. This capital structure shares optimally the non-diversifiable risk associated with costly and risky ventures. Furthermore, it uniquely sustains the optimal risk allocation if agents' personal wealth is contractible at a higher enforcement cost than the projects' returns. Otherwise, the irrelevance theorem of Modigliani and Miller applies. Consistent with the theoretical predictions, we observe that (i) risk-averse merchants-entrepreneurs financed part of their ventures (hold inside equity) and raised additional funds from risk-averse investors through debt-like sea loan and equity-like commenda contracts when long-distance medieval trade was indeed highly costly and risky and that (ii) maritime insurance, with higher protection against the non-diversifiable "risk of loss at sea or from the action of men" but higher enforcement costs, did not develop until the mid-fourteenth century, when the ventures' costs and risk had decreased significantly. Whereas the model emphasizes the entrepreneurs' equity holdings and the limited-liability aspects of debt and equity, the choice between debt or equity derives from simple, although historically backed, information assumptions. The analysis is therefore complementary to other capital-structure theories based on agency costs, information asymmetries, signalling, transaction costs and incomplete contracting.
