Knowledge that Transforms

This article applies the methodology of Bai and Ng (2002, 2004) for decomposing panel data into systematic and idiosyncratic components to both stock returns and turnover panels. This approach works well for both returns and turnover, despite the presence of severe heteroscedasticity and nonstationarity of individual stocks' turnover. We test the mutual fund separation model of Lo and Wang (2000). Trading due to systematic risk in returns can account for 66% of systematic turnover. Thus, portfolio rebalancing due to systematic risk is a very important motive for stock trading. Finally, several common turnover measures may understate the impact of stock trading.

In the IPO market, investors coordinate on acceptable IPO price based on the performance of past IPOs, and this generates an incentive for investment banks to produce information about IPO firms. In hot periods, the information produced by investment banks improves the quality of IPO firms, and this allows ex ante low quality firms to go public and increases the secondary market price, thus synchronizing high IPO volumes and high first day returns. When investment banks behave asymmetrically in information production, the "reputations" of investment banks are interpreted as a form of market segmentation to economize on the social cost of information production.

This article shows that investors financing a portfolio of projects may use the depth of their financial pockets to overcome entrepreneurial incentive problems. Competition for scarce informed capital at the refinancing stage strengthens investors' bargaining positions. And yet, entrepreneurs' incentives may be improved, because projects funded by investors with “shallow pockets” must have not only a positive net present value at the refinancing stage, but one that is higher than that of competing portfolio projects. Our article may help understand provisions used in venture capital finance that limit a fund'sinitial capital and make it difficult to add more capital once the initial venture capital fund is raised.

We examine a sample of 125 equity mutual funds that closed to new investment between 1993 and 2004. We find that funds close following a period of superior performance and abnormal fund inflows. Fund managers raise their fees when they close to compensate managers for losses in income due to the restrictions in size imposed by the fund closure decision. Managers reopen when fund size declines. However, they do not earn superior returns after reopening, suggesting that the fund closure decision does not provide information about superior fund managers. (JEL G14, G23)

The bookbuilding IPO procedure has captured significant market share from auction alternatives recently, despite the significantly lower costs related to the auction mechanism. In France, where both mechanisms were used in the 1990s, the ostensible advantages of bookbuilding were advertising-related benefits. Book-built issues were more likely to be followed and positively recommended by lead underwriters. Even nonunderwriters' analysts promote book-built issues more in order to curry favor with the IPO underwriter for allocations of future deals. Yet we do not observe valuation or post-IPO return differentials that suggest these types of promotion have any value to the issuing firm.

In certain circumstances, insider trades such as private transactions between executives and their firms could be disclosed after the end of the firm's fiscal year, on a Form-5 filing. We find that insider sales disclosed in such a delayed manner for large firms are predictive of negative future returns (−6 to −8 percent), as well as lower future annual earnings relative to analyst forecasts. These results stand in contrast to existing findings on the uninformativeness of quickly disclosed open-market insider sales. The Sarbanes-Oxley Act curtailed the use of Form 5 under the presumption that managers used this vehicle opportunistically. Our systematic evidence supports this presumption.

In 2001, the Securities and Exchange Commission (SEC) required market centers to publish monthly execution-quality reports in an effort to spur competition for order flow between markets. Using samples of stocks trading on several markets, we investigate whether past execution quality affects order-routing decisions and whether the new disclosure requirements influence this relationship. We find that routing decisions are associated with execution quality; markets reporting low execution costs and fast fills subsequently receive more orders. Moreover, the reports themselves appear to provide information that was unavailable previously. Our results are consistent with active competition for order flow that can be influenced by public disclosure. (JEL G24, G28, K22)

We provide new evidence on termination provisions and the takeover bidding process. Our central contribution is a novel database from Securities and Exchange Commission (SEC) documents that accurately measures the incidence of termination provisions and the depth of competition in takeover deals. We show that biased data in prior research produced incorrect conclusions on the relation between termination provisions and judicial decisions, bidder toeholds, and deal size. Our comprehensive data also show that termination provisions are positively related to takeover competition. Our evidence is consistent with the information/commitment hypothesis in which termination provisions do not truncate bidding but instead culminate the takeover process. (JEL G34; K22; D44).

This study examines how heterogeneity of private information may induce financial contagion. Using a model of multi-asset trading in which the three main channels of contagion through financial linkages in the literature (correlated information, correlated liquidity, and portfolio rebalancing) are ruled out by construction, I show that financial contagion can still be an equilibrium outcome when speculators receive heterogeneous fundamental information. Risk-neutral speculators trade strategically across many assets to mask their information advantage about one asset. Asymmetric sharing of information among them prevents rational market makers from learning about their individual signals and trades with sufficient accuracy. Incorrect cross-inference about terminal payoffs and contagion ensue. When used to analyze the transmission of shocks across countries, my model suggests that the process of generation and disclosure of information in emerging markets may explain their vulnerability to financial contagion.

This article explores the implications of additive and endogenous habit formation preferences in the context of a life-cycle model of an investor who has stochastic uninsurable labor income. To solve the model, I analytically derive the habit-wealth feasibility constraints and show that they depend on the worst possible path of future labor income and on the habit strength, but not on the probability of the worst income. When there is only a slim chance of a severe income shock, the model implies much more conservative portfolios. The model also predicts that for some low to moderately wealthy households, the portfolio share allocated to stocks increases with wealth. Because of this feature, the model can generate more conservative portfolios for younger than for middle-aged households. The effects of habits on portfolio choice are robust to income smoothing through borrowing or flexible labor supply. One controversial finding is that for high values of the habit strength parameter, usually required for the resolution of asset pricing puzzles in general equilibrium, the life-cycle model predicts counterfactually high wealth accumulation.
