One might be tempted to conclude that good risk management in banks reduces the exposure to danger. However, such a view of risk management ignores that banks cannot succeed without taking risks that are ex ante profitable. Consequently, taking actions that reduce risk can be costly for shareholders when lower risk means avoiding valuable investments and activities that have higher risk. Therefore, from the perspective of shareholders, better risk management cannot mean risk management that is more effective at reducing risk in general since reducing risk in general would mean not taking valuable projects. If good risk management does not mean low risk, then what does it mean? How is it implemented? What are its limitations? What can be done to make it more effective? In my article, Governance, Risk Management, and Risk-Taking in Banks, which was recently made publicly available on SSRN, I provide a framework to understand the role, the organization, and the limitations of risk management in banks when it is designed from the perspective of increasing the value of the bank for its shareholders and review the existing literature.

Recent events in Europe have illustrated how government defaults can jeopardize domestic bank stability. Growing concerns of public insolvency since 2010 caused great stress in the European banking sector, which was loaded with Euro-area debt (Andritzky (2012)). Problems were particularly severe for banks in troubled countries, which entered the crisis holding a sizable share of their assets in their governments’ bonds: roughly 5% in Portugal and Spain, 7% in Italy and 16% in Greece (2010 EU Stress Test). As sovereign spreads rose, moreover, these banks greatly increased their exposure to the bonds of their financially distressed governments (2011 EU Stress Test), leading to even greater fragility. As The Economist put it, “Europe’s troubled banks and broke governments are in a dangerous embrace.” These events are not unique to Europe: a similar relationship between sovereign defaults and the banking system has been at play also in earlier sovereign crises (IMF (2002)).
Excessive risk-taking by financial institutions and overly generous executive pay are widely regarded as key factors in the 2007-09 crisis. In particular, it has become commonplace to blame banks and securities companies for compensation packages that reward managers (and more generally, other risk-takers such as traders and salesmen) generously for making investments with high returns in the short run but large risks that emerge only in the long run. As governments have been forced to rescue failing financial institutions, politicians and the media have stressed the need to cut executive pay packages and rein in incentives based on options and bonuses, making them more dependent on long-term performance and in extreme cases eliminating them outright. It is natural to ask whether this is the right policy response to the problem. It is crucial to ask what is the root of the problem—that is, precisely which market failure produced excessive risk-taking.
High-water mark (HWM) contracts are the predominant compensation structure for managers in the hedge fund industry. In the paper, Risk Choice under High-Water Marks, forthcoming in the Review of Financial Studies, I seek to understand the optimal dynamic risk-taking strategy of a hedge fund manager who is compensated under such a contract. This is both an interesting portfolio-choice question, and one with potentially important ramifications for the willingness of hedge funds to bear risk in their role as arbitrageurs and liquidity providers, especially in times of crises. High-water mark mechanisms are also implicit in other types of compensation structures, so insights from this question extend beyond hedge funds. An example is a corporate manager who is paid performance bonuses based on record earnings or stock price and whose choice of projects influences the firm’s level of risk.
Last week, James Kwak (UConn law professor, co-author of 13 Bankers and White House Burning, and blogger at the Baseline Scenario) provided a nice writeup of some of the key issues I identify in my paper, Understanding the Failures of Market Discipline, recently posted to SSRN. But I wanted to take a few words to provide a slightly more detailed explanation of my work.
“Market discipline”—the notion that short-term creditors (such as bank depositors) can efficiently identify and rein in bank risk—has been a central pillar of banking regulation since the 1980s. Obviously, market discipline did not prevent the buildup of bank risk that caused the recent financial crisis, but the general consensus has been that this failure was due to structural impediments to the effective operation of market discipline—such as misaligned incentives, a lack of transparency, or moral hazard caused by implicit guarantees—rather than any problems with the concept itself. As a result, a major point of emphasis in financial regulatory reform efforts has been to improve and strengthen market discipline.
In our recent NBER working paper, Financing as a Supply Chain: The Capital Structure of Banks and Borrowers, we propose a novel framework to model joint debt decisions of banks and borrowers. Our framework combines the models used by bank regulators with the models used to explain capital structure in corporate finance. This structure can be used to explore the quantitative impact of government interventions such as deposit insurance, bailouts, and capital regulation.
In our paper, CEO Job Security and Risk-Taking, which was recently made publicly available on SSRN, we use the length of employment contracts to estimate CEO turnover probability and its effects on risk-taking. Protection against dismissal should encourage CEOs to pursue riskier projects. Indeed, we show that firms with lower CEO turnover probability exhibit higher return volatility, especially idiosyncratic risk. An increase in turnover probability of one standard deviation is associated with a volatility decline of 17 basis points. This reduction in risk is driven largely by a decrease in investment and is not associated with changes in compensation incentives or leverage.
In our paper, Managerial Risk Taking Incentives and Corporate Pension Policy, forthcoming in the Journal of Financial Economics, we examine whether the compensation incentives of top management affect the extent of risk shifting versus risk management behavior in pension plans.
The employee beneficiaries of a firm’s defined benefit pension plan hold claims on the firm similar to those held by the firm’s debtholders. Beneficiaries are entitled to receive a fixed stream of cash flows starting at retirement. The firm sponsoring the plan is required to set aside assets in a trust to fund these obligations, but if the sponsor goes bankrupt with insufficient assets to fund pension obligations, beneficiaries are bound to accept whatever reduced payouts can be made with the assets secured for the plan.
There has been a recent surge in research that seeks to understand the sources of variation in tax avoidance (e.g., Shevlin and Shackelford, 2001; Shevlin, 2007; Hanlon and Heitzman, 2010). The benefits of tax avoidance can be economically large (e.g., Scholes et al., 2009) and tax avoidance can be a relatively inexpensive source of financing (e.g., Armstrong et al., 2012). However, aggressive tax avoidance may be accompanied by substantial observable (e.g., fines and legal fees) and unobservable (e.g., excess risk and loss of corporate reputation) costs. Although understanding the factors that influence managers’ tax avoidance decisions is an important research question that has broad public policy implications, relatively little is known about why some firms appear to be more tax aggressive than others.
In our paper, Corporate Governance, Incentives, and Tax Avoidance, which was recently made publicly available on SSRN, we examine whether variation in firms’ corporate governance mechanisms explains differences in their level of tax avoidance. We view tax avoidance as one of many investment opportunities that is available to managers. Similar to other investment decisions, managers have personal incentives to engage in a certain amount of tax avoidance that may not be in the best interest of shareholders, thereby giving rise to an agency problem. From the perspective of the firm’s shareholders, unresolved agency problems with respect to tax avoidance can manifest as either “too little” or “too much” tax avoidance. As with other agency problems, certain corporate governance mechanisms can mitigate agency problems with respect to tax avoidance.
In our paper, Downside Risk and the Design of CEO Incentives: Evidence from a Natural Experiment, which was recently made publicly available on SSRN, we investigate how downside risk influences the design of CEOs’ incentives. Studying the relationship between firm risk and managerial incentives is a difficult task due to the endogenous nature of the relationship: empiricists cannot easily disentangle the effect of compensation on risk from the effect of risk on compensation (Prendergast, 2002). We address the identification challenge by exploiting a randomized natural experiment that exogenously increased downside equity risk through the relaxation of short-selling constraints. Because the removal of short-selling constraints may cause an increase – or the fear of an increase – in bear raids and market manipulation by short-sellers (Goldstein and Guembel (2008)), this increase in downside risk potentially exposes managers to losses that are beyond their control. In this scenario, CEOs may sub-optimally reduce the risk of their firms to protect their personal wealth and firm-specific human capital (Amihud and Lev (1981), May (1995)). Consistent with this view, firms and their CEOs display an acute aversion to short-sellers, and go to great lengths to fight them and reduce their influence on stock prices (Lamont (2012)). As a result, firms that maximize shareholder value should respond to an exogenous increase in short selling activity by increasing their CEOs’ risk-taking incentives to avoid sub-optimal risk reduction policies, and/or by immunizing their CEOs against the downside risk that lies outside of their control and does not reflect their performance.
