摘要：A dynamic model of a multistage investment project that captures many features of research and development (R&D) ventures and start-up companies is developed. An important feature these problems share is that firms learn about the potential profitability of the project throughout its life, but that technical uncertainty about the R&D effort is only resolved through additional investment. Consequently the risks associated with the ultimate cash flows have a systematic component even while the p...

摘要：While IPOs have been underpriced by more than 10% during the past two decades, we find that in a sample of more than 2,000 IPOs from 1980 to 1997, the median IPO was significantly overvalued at the offer price relative to valuations based on industry peer price multiples. This overvaluation ranges from 14% to 50% depending on the peer matching criteria. Cross-sectional regressions show that overvalued IPOs provide high first-day returns, but low long-run risk-adjusted returns. These overvalued...

摘要：We investigate resource allocation decisions in conglomerates when managers are motivated by career concerns. When divisional cash flows are differentially informative about managerial ability, we show that it is in the managers' interest to over-allocate unobservable intangible resources to the more informative divisions. Anticipating this bias, it is optimal for the firm's owners to also over-allocate observable capital to the more informative divisions. The model provides rationale for corp...

摘要：Little is known about the timing and execution of open market repurchases. U.S. firms are under no obligation to disclose when they are trading, and generally report only quarterly changes in shares outstanding. We use 64 firms' supplementally disclosed repurchase trading data to provide the first examination of repurchase timing and execution. Across the days reported in our sample, firms adopted a variety of execution styles ranging from immediate intense repurchasing to delayed and smoothed...

摘要：We show that bidding firms consider target board characteristics when deciding takeover offer types and initial offer premiums. We study a sample of 436 proposed negotiated mergers and bypass offers. Firms with individuals holding the titles of both chief executive officer (CEO) and board chair are more likely to receive bypass offers. These offers are more likely to be successful and generate higher target shareholder gains over the takeover offer period. When the target's board is independen...

摘要：This article characterizes the systematic risk exposures of hedge funds using buy-and-hold and option-based strategies. Our results show that a large number of equity-oriented hedge fund strategies exhibit payoffs resembling a short position in a put option on the market index and therefore bear significant left-tail risk, risk that is ignored by the commonly used mean-variance framework. Using a mean-conditional value-at-risk framework, we demonstrate the extent to which the mean-variance fra...

摘要：We examine Japan's 1997 introduction of book building as an alternative to a previously required hybrid auction method. Despite higher cost for some issuers, all issuers in Japan now select book building. Book building enables more accurate valuation of firms, but gains from accurate valuation are partly redistributive. Thus book building can drive auction-method offerings from the market even if it yields no aggregate benefit. Compared to the auction regime, book building reduces issue costs ...

摘要：The apparent conflict between the level of resources dedicated to technical analysis by practitioners and academic theories of market efficiency is a long-standing puzzle. We explore a previously unexamined feature of technical analysis-namely its relation to liquidity provision. We demonstrate that support and resistance levels coincide with peaks in depth on the limit order book and moving average forecasts reveal information about the relative position of depth on the book. Furthermore, we ...

摘要：I present a new approach to the dynamic portfolio and consumption problem of an investor who worries about model uncertainty (in addition to market risk) and seeks robust decisions along the lines of Anderson, Hansen, and Sargent (2002). In accordance with max-min expected utility, a robust investor insures against some endogenous worst case. I first show that robustness dramatically decreases the demand for equities and is observationally equivalent to recursive preferences when removing weal...

摘要：This article presents a general framework for identifying and modeling the joint-tail distribution based on multivariate extreme value theories. We argue that the multivariate approach is the most efficient and effective way to study extreme events such as systemic risk and crisis. We show, using returns on five major stock indices, that the use of traditional dependence measures could lead to inaccurate portfolio risk assessment. We explain how the framework proposed here could be exploited i...
