We examine the relation between earnings smoothing and stock price crash risk to evaluate the role of earnings smoothing on the downside risk of equity values. We find that, within firm, a higher degree of earnings smoothing is associated with greater crash risk; and this association, in the cross-section, is more pronounced for firms with fewer analysts following, smaller institutional holdings, and positive cumulative discretionary accruals. We also use stock returns to assess the economic significance of our results. We find that, controlling for firm fixed effects, earnings smoothing is associated with sizable negative returns in the quarter following the earnings announcement. Our findings caution investors about the downside risk of firms reporting smooth earnings, in contrast to the conventional belief that these firms are low in equity risk.

Institutions often offer a menu of contracts to consumers in an attempt to create a separating equilibrium that reveals borrower types and provides better pricing. We test the effectiveness of a specific set of contracts in the mortgage market: mortgage points. Points allow borrowers to exchange an upfront amount for a decrease in the mortgage rate. We document that, on average, points takers lose about $700. Also, points takers are less financially savvy (less educated, older), and they make mistakes on other dimensions (e.g., inefficiently refinancing their mortgages). Overall, our results show that borrowers overestimate how long they will stay with the mortgage.

We examine the real effects of mandatory social-responsibility disclosures, which require SEC-registered mine owners to include their mine-safety records in their financial reports. These safety records are already publicly available elsewhere, which allows us to isolate and estimate the incremental real effects of including this information in financial reports. Comparing mines owned by SEC-registered issuers with mines that are not, we document that including safety records in financial reports decreases mining-related citations and injuries, and reduces labor productivity. Evidence from stock-market reactions and mutual-fund holdings suggests that increased awareness of safety issues is a likely explanation for the observed real effects.

Security trading now fragments into more than ten almost identical stock exchanges in the United States. We show that discrete pricing is one economic force that prevents the consolidation of trading volume. The uniform one-cent tick size (minimum price variation), imposed by the SEC's Rule 612, leads to more dispersed trading for lower priced securities. When a security reverse splits, its price increases and relative tick size (one cent divided by the price) decreases. We find that reverse splits consolidate trading of securities, using securities with identical underlying fundamentals that do not reverse split as the control group.

Studying the only mandatory pre-IPO market in the world—Taiwan’s Emerging Stock Market (ESM)—we document that pre-market prices are very informative about post-market prices and that informativeness increases with a stock’s liquidity. The ESM price-earnings ratio shortly before an initial public offering explains about 90% of the variation in the offer price-earnings ratio. However, the average IPO underpricing level remains high, at 55%, suggesting that agency problems between underwriters and issuers can lead to excessive underpricing, even with little valuation uncertainty. Also, regulations impact the relative bargaining power of players and therefore IPO pricing.
