MIT Roundtable on Corporate Risk Management

Abstract

Against the backdrop of financial crisis, a distinguished group of academics and practitioners discusses the contribution of financial management and innovation to corporate growth and value, along with the pitfalls and unintended consequences of such innovation. The main focus of most panelists is the importance of a capital structure and risk management approach that complement the strategy and operations of the business. Instructive examples are provided by Judy Lewent, former CFO and head of strategic planning at Merck, and Lakshmi Shyam-Sunder, director of finance and risk management at the International Finance Corporation.

But if these represent successful applications of finance theory, what about the large number of cases where the use of derivatives and other innovations has led to high leverage and apparent risk management failures? Part of the current trouble, as pointed out by Andrew Lo, can be attributed to the failure of risk managers and their models to account for highly improbable events—the so-called fat tails of the distribution. But, as Robert Merton suggests in closing, there is a more comprehensive explanation for today's problems: the tendency of market participants to respond to potentially risk-reducing financial innovation by increasing their risk-taking in other areas. "What we have here," says Merton, are two partly offsetting effects of innovation—one that is reducing the risk of companies and their investors, and another that is encouraging greater risk-taking. From a social or regulatory standpoint, the goal is to find the right balance between these two effects or forces.

Customers and Investors: A Framework for Understanding Financial Institutions

Robert C. Merton and Robert T. Thakor

Financial institutions have both investors and customers. Investors, such as those who invest in stocks and bonds or private/public-sector guarantors of institutions, expect an appropriate risk-adjusted return in exchange for the financing and risk-bearing that they provide. Customers of a financial intermediary, in contrast, provide financing in exchange for a specific set of services, and do not want the fulfillment of these services to be contingent on the credit risk of the intermediary, even when they are not small, uninformed agents lacking in sophistication. This paper develops a framework that defines the roles of customers and investors in intermediaries, and uses the framework to provide an economic foundation for the aversion to intermediary credit risk on the part of its customers. It further explores the implications of this customer-investor nexus for a host of issues related to how contracts between financial intermediaries and their customers are structured and how risks are shared between them, as well as the consequences of (unexpected) deviations from the ex ante optimal contractual arrangement. We show that the optimality of insulating the customer from the credit risk of the intermediary explains various contractual arrangements, institutions, and regulatory practices observed in practice. Moreover, customers and investors are often intertwined in practice, and so this intertwining provides insights into the adoption of "too-big-to-fail" policies and bailouts by regulators in general. Finally, the approach taken here shows that financial crises may be a consequence of observed but unexpected deviations from the ex ante optimal risk-sharing arrangement between financial intermediaries and their customers.

Corporate America began to really take notice of the looming retirement crisis in the wake of the dot-com crash, when companies in major industries went bankrupt in large part because of their inability to meet their pension obligations. The result was an acceleration of America's shift away from employer-sponsored pension plans toward defined-contribution (DC) plans—epitomized by the ubiquitous 401(k)—which transfer the investment risk from the company to the employee. With that transfer has come a dangerous shift in investment focus, argues Nobel Laureate Robert C. Merton. Traditional pension plans were conceived and managed to provide members with a guaranteed income. And because that objective filtered right through the scheme, members thought of their benefits in those terms. Ask a member what her pension is worth and she'll reply with an income figure: "two-thirds of my final salary," for example. Most DC schemes, however, are designed and managed as investment accounts with the goal of accumulating the largest possible pot of savings. Communication with savers is framed entirely in terms of assets and returns. Ask a saver what his 401(k) is worth and you'll hear a cash amount and perhaps a lament to the value lost in the financial crisis. The trouble is that investment value and asset volatility are simply the wrong measures if your goal is to secure a particular future income. In this article, Merton explains a liability-driven investment strategy whose aim is to improve the probability of achieving a desired retirement income rather than to maximize the capital value of the savings.
