Asset Management

A basket default swap is a derivative security tied to an underlying basket of corporate bonds or other assets subject to credit risk. The value of the contract depends on the joint distribution of the default times of the underlying assets. Valuing a basket default swap often entails Monte Carlo simulation of these default times. For baskets of high-quality credits and for swaps that require multiple defaults to trigger payment, pricing the swap is a rare-event simulation problem.

The pressure to meet/beat analysts' expectations is often blamed for the recent onslaught of accounting scandals. We investigate changes in the meeting/beating phenomenon post-scandals and find that the stock market premium to meeting or just beating analyst estimates has disappeared while the premium to beating by a larger margin has diminished. In the post-scandals period, managers tend to meet or just beat analysts' forecasts less often. Further, managers rely less on income-increasing discretionary accruals and more on earnings guidance.

Consider an economy in which the underlying security returns follow a linear factor model with constant coeffcients. While portfolios that invest in these securities will, in general, have a linear factor structure, it will be one with time-varying coeffcients. However, under certain assumptions regarding the portfolio's investment strategy, it is possible to estimate these time-varying alphas and betas.

Our results are broadly consistent with the predictions of a benign view of the role of investment banks in advising acquisition targets. Fees to investment banks are correlated with attributes of transactions and target firms in ways that make sense if banks are being paid for processing information. The more contingent (and, therefore, risky) the fees, the higher they tend to be, all else held constant. Variation in acquisition premia also can be explained by fundamental deal attributes.

I quantitatively measure the interactions between the media and the stock market using daily content from a popular Wall Street Journal column. I find that high media pessimism predicts downward pressure on market prices followed by a reversion to fundamentals, and unusually high or low pessimism predicts high market trading volume.

This paper lays out a decomposition of book-to-price (B/P) that derives from the accounting for book value and that articulates precisely how B/P "absorbs" leverage. The B/P ratio can be decomposed into an enterprise book-to-price (that pertains to operations and potentially reflects operating risk) and a leverage component (that reflects financing risk).

The article shows that two measures of the amount of private information in stock price — price nonsynchronicity and probability of informed trading (PIN) — have a strong positive effect on the sensitivity of corporate investment to stock price. Moreover, the effect is robust to the inclusion of controls for managerial information and for other information-related variables. The results suggest that firm managers learn from the private information in stock price about their own firms’ fundamentals and incorporate this information in the corporate investment decisions.

Contrary to the common perception that operating cash flows are better than accounting earnings at explaining equity valuations, recent studies suggest that valuations derived from industry multiples based on reported earnings are closer to traded prices than those based on reported operating cash flows.

Public/private partnerships have become a favored strategy for implementing complex urban developments in the United States and Western Europe, but the large volume of literature on the topic falls short of providing city planners, development experts, and policy analysts the knowledge needed for either teaching or practice. In the late 1970s, the blurring of lines between public and private action spurred significant intellectual debate in the U.S.
