Investment-based asset pricing models typically predict a close link between a firm’s stock return and its characteristics at any point in time. Yet, previous studies have primarily focused on the weaker prediction that this link holds on average, finding substantial empirical support. We show how to incorporate the time-series predictions in the estimation and testing of investment-based models using the generalized method of moments. We find that standard specifications of investment-based models with one physical capital input fail to match the time series properties of stock returns in the data, and discuss the implications of the findings for future research.

Do stock prices of publicly listed companies respond to changes in transaction costs? Using the SEC’s pilot program that increased the tick size for approximately 1,200 randomly chosen stocks, we find a stock price decrease between 1.75% and 3.2% for small spread stocks affected by the larger tick size relative to a control group. We find that the increase in the present value of transaction costs accounts for a small percentage of the price decrease. We study channels of price variation due to changes in expected returns: information risk, investor horizon, and liquidity risk. The evidence suggests that trading frictions affect the cost of capital.

We develop a stock return-predictive measure based on an efficient aggregation of the portfolio holdings of all actively managed U.S. domestic equity mutual funds, and use this model to study the source of fund managers' stock-selection abilities. This generalized-inverse alpha (GIA) approach reveals differences in the ability of managers to predict firms' future earnings from fundamental research. Notably, the GIA's return-forecasting power is not subsumed by publicly available quantitative predictors, such as momentum, value, and earnings quality, nor is it subsumed by methods shown in past research to forecast stock returns using fund holdings or trades.

[We examine how experience affects the decisions of individual investors and institutions in IPO auctions to bid in subsequent auctions, and their bidding returns. We track bidding histories for all 31,476 individual investors and 1,232 institutional investors across all 84 IPO auctions during the period from 1995 to 2000 in Taiwan. For individual bidders, (1) high returns in previous IPO auctions increase the likelihood of participating in future auctions; (2) bidders' returns decrease as they participate in more auctions; (3) auction selection ability deteriorates with experience; and (4) those with greater experience bid more aggressively. These findings are consistent with naïve reinforcement learning wherein individuals become unduly optimistic after receiving good returns. In sharp contrast, there is little sign that institutional investors exhibit such behavior.]

Using exogenous shocks on the ability to issue seasoned equity offerings (SEOs), we show SEOs lead to a higher employee skill composition, that is, a lower (higher) proportion of low (high) skilled workers. The decrease in low-skilled workers exceeds the increase in high-skilled workers, resulting in reduced employment at the firm level. These effects are more significant when firms invest more in technology following SEOs and face greater financial constraints before SEOs, suggesting that SEOs relieve budget constraints on technology investments. These findings demonstrate that while external equity financing helps upgrade technology to improve productivity, it has a dark side for low-skilled workers.

Based on a survey of 1, 268 firms in 12 cities, this article empirically studies unions' effects on worker welfare in China. Regressions carried out on a rich set of specifications show that unionization is significantly associated with higher hourly wages and larger pension coverage and weakly associated with lower monthly working hours. Further econometric analysis finds that unions promote individual and collective contracts. The effect of collective contracts vanishes when unions are present, whereas individual contracts have independent and positive effects. In addition, unions have effects on workers' welfare independent of collective and individual contracts.

We analyze split award procurement auctions in which a buyer divides full production between two suppliers or awards all production to a single supplier, and suppliers have private cost information. An intriguing feature of split awards is that the equilibrium bids are implicitly coordinated. Because a split award price is the sum of offered split prices, each supplier can unilaterally veto a split award by bidding very high for the split. The need to coordinate is reflected in a split price that does not vary with private information. We also explore conditions under which split award auctions may be preferred to winner-take-all auctions.

Active equity mutual funds managed by insurance companies underperform peer funds by over 1% per year. There is no evidence that insurance funds make less risky investments; instead they have lower risk-adjusted returns and their fund flows are less sensitive to performance when they perform poorly. Across insurance funds, those with heavy advertising, directly established by insurers or using parent firms' brandnames, and those whose managers simultaneously manage substantial non-mutual-fund assets, are more likely to underperform. We conclude that insurers' efforts to cross-sell mutual funds aggravate agency problems that erode fund performance.

Managers’ incentives to round up reported earnings per share (EPS) cause an underrepresentation of the number 4 in the first post-decimal digit of EPS, or “quadrophobia.” We develop a novel measure of aggressive financial reporting practices based on a firm’s history of quadrophobia. Quadrophobia is pervasive, persistent, and successfully predicts future restatements, Securities and Exchange Commission enforcement actions, and class action litigation. It is more pronounced when executive compensation is more closely tied to the stock price and when the firm anticipates violating debt covenants. Quadrophobia is especially strong when rounding-up EPS allows firms to meet analyst expectations, and investors seem not to see through this behavior.
