The Marginal Value of Cash: Structural Estimates from a Model with Financing and Agency Frictions
构建了一个包含融资和代理成本的理论模型，并基于该模型结构估计了企业现金的边际价值，发现现金和资本存量大的公司现金边际价值更低，而杠杆与现金边际价值呈驼峰形关系。
How much value does an additional dollar of cash create for a firm? It is generally recognized that the marginal value of cash (MVC) can either exceed or fall below one dollar. Estimates of MVC can guide corporate cash and payout policy, indicate the quality of governance, and make a firm a target for takeover or activism. Yet the existing methods of estimation lack a rigorous theoretical foundation and often provide implausibly high or low estimates. In this paper, we provide a formulation of MVC and structurally estimate the MVC based on a model that encompasses the important determinants for the choice of cash savings, including financing and agency costs. We find that firms with large cash and capital stocks have lower marginal value of cash, whereas the relationship between leverage and marginal value of cash is hump shaped. Two quasi-natural experiments validate the MVC estimates. This paper was accepted by Lukas Schmid, finance. Funding: D.
