Twenty-seven percent of the Union Army prisoners captured July 1863 or later died in captivity. At Andersonville, the death rate may have been as high as 40 percent. How did men survive such horrific conditions? Using two independent datasets, we find that friends had a statistically significant positive effect on survival probabilities and that the closer the ties between friends as measured by such identifiers as ethnicity, kinship, and the same hometown, the bigger was the impact of friends on survival probabilities.

While neoclassical models assume static cost-minimization by firms, agency models suggest that firms may not minimize costs in less-competitive or regulated environments. We test this using a transition from cost-of-service regulation to market-oriented environments for many US electric generating plants. Our estimates of input demand suggest that publicly owned plants, whose owners were largely insulated from these reforms, experienced the smallest efficiency gains, while investor-owned plants in states that restructured their wholesale electricity markets improved the most. The results suggest modest medium-term efficiency benefits from replacing regulated monopoly with a market-based industry structure. (JEL D24, L11, L51, L94, L98)

ABSTRACT We develop a new model of multimarket trading to explain the differences in the foreign share of trading volume of internationally cross‐listed stocks. The model predicts that the trading volume of a cross‐listed stock is proportionally higher on the exchange in which the cross‐listed asset returns have greater correlation with returns of other assets traded on that market. We find robust empirical support for this prediction using stock return and volume data on 251 non‐U.S. stocks cross‐listed on major U.S. exchanges.

In recent years, many companies have emphasized adjusted-GAAP earnings numbers in their quarterly press releases. While managers use different names to describe these nonstandard earnings metrics, the financial press frequently refers to them as “pro forma” earnings. Managers and other advocates of pro forma reporting argue that these disclosures provide a clearer picture of companies' core earnings. On the other hand, regulators, policymakers, and the financial press often allege that managers' pro forma earnings disclosures are opportunistic attempts to mislead investors. Recent evidence suggests that while many pro forma earnings disclosures are altruistically motivated, some may represent managers' attempts to portray overly optimistic financial performance. If this is the case, then less wealthy, less sophisticated, individual investors are arguably the most at risk of being misled. Consequently, this study investigates who trades on pro forma earnings information. Our intraday investigation of transactions around earnings announcements containing pro forma earnings information reveals that less sophisticated investors' announcement-period abnormal trading is significantly positively associated with the magnitude and direction of the earnings surprise based on pro forma earnings. In contrast, we find no association between sophisticated investors' trading and manager-reported pro forma information. Overall, our analyses and numerous robustness tests suggest that the segment of the market that relies on pro forma earnings information is populated predominantly by less sophisticated individual investors. This evidence is particularly relevant to standard-setters and regulators given that Section 401(b) of the Sarbanes-Oxley Act of 2002 and subsequent SEC regulations are specifically designed to protect ordinary investors from misleading pro forma information.
