The sub-prime crisis: A central banker's perspective

Journal of Financial Stability 2008 4(4), 313-320
The crisis is not yet over; the housing market continues to deteriorate and there are spill-overs into other markets. Growth is declining, with potentially self re-enforcing mechanisms between financial markets and the real economy coming into play. A local problem became a global crisis because of poor risk management, lack of transparency and excessive leverage. Not only does the capital base need re-building, but also incentive schemes need reconsideration.

The role of profit-based and stock-based components in incentive compensation

Journal of Financial Intermediation 2008 17(3), 357-378 open access
This paper argues that the presence of both profit-based and stock price-based components in compensation contracts provides senior managers the incentive to optimally allocate effort to both implementing previously devised strategies that provide current profits and to formulating new strategies that create shareholder value. If managers are concerned about their reputation and if outcomes of strategy implementation are more informative about their ability than outcomes of strategy formulation, compensation based only on profit will incent managers to boost their reputation by over-allocating effort to strategy implementation. To restore the balance the contract needs to contain some stock-based compensation.

Bank capital structure and credit decisions

Journal of Financial Intermediation 2008 17(3), 295-314
This paper argues that banks must be sufficiently levered to have first-best incentives to make new risky loans. This result, which is at odds with the notion that leverage invariably leads to excessive risk taking, derives from two key premises that focus squarely on the role of banks as informed lenders. First, banks finance projects that they do not own, which implies that they cannot extract all the profits. Second, banks conduct a credit risk analysis before making new loans. Our model may help understand why banks take on additional unsecured debt, such as unsecured deposits and subordinated loans, over and above their existing deposit base. It may also help understand why banks and finance companies have similar leverage ratios, even though the latter are not deposit takers and hence not subject to the same regulatory capital requirements as banks.

Corporate asset purchases and sales: Theory and evidence☆

Journal of Financial Economics 2008 87(2), 471-497 open access
Purchases and sales of operating assets by firms generated $162 billion for shareholders over the past 20 years. This contrasts sharply with the evidence on mergers. This paper characterizes the behavior of value-maximizing firms, which could grow organically, purchase existing assets, or sell assets. The approach yields an endogenous selection model that links asset purchases and sales to fundamental properties of the firm. Empirical tests confirm the predictions of the model. In particular, return on assets and size strongly predict when firms purchase or sell assets, and the transaction size covaries with the value of capital employed by the firm. These findings indicate that corporate asset purchases and sales are consistent with efficient investment decisions.

Do weak supervisory systems encourage bank risk-taking?

Journal of Financial Stability 2008 4(1), 23-39
Weak bank supervision could give banks the ability to shift risk from themselves to supervisors. We use cross-border bank mergers as a natural experiment to test changes in risk and the impact of supervision. We examine cross-border bank mergers and find that the supervisory structures of the partners’ countries influence changes in post-merger total risk. An acquirer from a country with strong supervision lowers total risk after a cross-border merger. However, total risk increases when the target bank is located in a country with relatively strong supervision. This result is consistent with strong host regulators limiting the risky activities of their local banks. Foreign-owned competitors could then engage in the risky projects, especially if the foreign banks’ supervisors are not strong. An acquirer entering a country with strong supervision appears to shift risk back to its home country. The results suggest that bank supervisors can reduce total banking risk in their countries by being strong.

The determinants of market-wide issue cycles for initial public offerings

Journal of Corporate Finance 2008 14(5), 567-583
This paper identifies the determinants of market-wide issue cycles for initial public offerings (IPOs) using an autoregressive conditional count model. We consider whether IPO volume is related to business conditions, investor sentiment, and time variation in adverse selection costs caused by asymmetric information between managers and investors. We provide evidence indicating that time variation in business conditions and investor sentiment are important determinants of monthly issue activity. By contrast, time variation in adverse selection costs does not significantly affect IPO volume.

Retirement and Consumption in a Life Cycle Model

Journal of Labor Economics 2008 26(1), 35-71
Consumption expenditure declines sharply at the time of retirement for many households, but the majority maintain a smooth consumption path. A simple life cycle model with uncertainty about the time of retirement can account for this pattern. A richer version of the model is calibrated to data from the Health and Retirement Study (HRS). The median change in consumption expenditure at retirement generated by the model is zero, while the mean is negative, matching the HRS data. However, the magnitude of the drop in consumption among households that experience a decline is too small in the model compared to the data.

How do IMF announcements affect financial markets in crises?

Journal of Financial Stability 2008 4(2), 121-134
We employ a theoretical model to interpret the liquidity and moral hazard effects of IMF support during a financial crisis. We then estimate the response of forward exchange markets to IMF-related announcements, using data on the 3-, 9-, and 12-month forward exchange rates. Our results indicate that the announcement of IMF negotiations is associated with a premium on the baht and the rupiah, where the premium is much larger on the latter. This result is largely consistent with the responses of stock and bond markets, especially when country-specific data are employed.

A Rent Extraction View of Employee Discounts and Benefits

Journal of Labor Economics 2008 26(3), 485-518
We examine how firms can use employee discounts and perks to extract information rents from employees who have private information about their preferences and outside opportunities. The firm creates different bundles of the perk and salary in response to different employee characteristics and marginal costs of the perk. Strategic bundling can lead firms to provide perks even without a cost advantage over the outside market and to deviate from the marginal cost pricing. We characterize how optimal perk provision depends on the set of feasible contracts, on the perk’s marginal cost, and on the perk’s price in the outside market.
