Over the past thirty years, the use of child safety seats in motor vehicles has increased dramatically. There is, however, relatively little empirical evidence regarding the efficacy of child safety seats relative to the much cheaper alternative of traditional seat belts. Using data on all fatal crashes in the United States from 1975 to 2003, I find that child safety seats, in actual practice, do not provide any discernible improvement over adult lap and shoulder belts in reducing fatalities among children aged two to six. Lap-only belts are somewhat less effective, but still far superior to riding unrestrained.

In the US, Canada, UK, Germany, France, and Japan, the propensity to pay dividends is higher among larger, more profitable firms, and those for which retained earnings comprise a large fraction of total equity. Although there are hints of reductions in the propensity to pay dividends in most of the sample countries over the 1994–2002 period, they are driven by a failure of newly listed firms to initiate dividends when expected to do so. Dividend abandonment and the failure to initiate by existing nonpayers are economically unimportant except in Japan. Moreover, in each country, aggregate dividends have not declined and are concentrated among the largest, most profitable firms. Finally, outside of the US there is little evidence of a systematic positive relation between relative prices of dividend paying and non-paying firms and the propensity to pay dividends. Overall, these findings cast doubt on signaling, clientele, and catering explanations for dividends, but support agency cost-based lifecycle theories.

We investigate whether corporate finance incentives affect the extent of corporate hedging with property insurance. Using a database that contains detailed insurance information, we document a positive relation between the expected costs of distress and property insurance coverage. We also show that the dividend payout ratio is negatively associated with property insurance coverage, consistent with the view that firms with high payout ratios insure a smaller fraction of properties due to cash flows in excess of investment needs, easy access to capital markets, or both. Different incentives are important for the insurance deductible and limit of coverage, and the deductible and limit of coverage are substitutes.

Macro news can affect currency prices directly and indirectly via order flow. Past research shows that the direct effects of scheduled macro news account for less than 10% of daily price variance. This paper shows that the arrival of macro news can account for more than 30% of daily price variance. Two features of our analysis account for this finding: (1) We consider the broad spectrum of macro news items that market participants observe, not just scheduled announcements. (2) We allow the arrival of news to affect prices indirectly via its impact on the volatility of order flow. Our analysis shows that order flow variations contribute more to currency price dynamics following the arrival of public macro news than at other times. This is not consistent with news effects being common knowledge that is impounded in price directly. Roughly two-thirds of the total effect of macro news on the DM/$ exchange rate is transmitted via order flow.

We study the consequences of an exogenous upsurge in coca prices and cultivation in Colombia, where most coca leaf is now harvested. This shift generated only modest economic gains in rural areas, primarily in the form of increased self-employment earnings and increased labor supply by teenage boys. The rural areas that saw accelerated coca production subsequently became considerably more violent, while urban areas were affected little. These findings are consistent with the view that the Colombian civil conflict is fueled by the financial opportunities that coca provides and that rent-seeking by combatants limits the economic gains from coca.

Extending previous work on asset-based style factor models, this paper proposes a model that allows for the presence of structural breaks in hedge fund return series. We consider a Bayesian approach to detecting structural breaks occurring at unknown times and identifying relevant risk factors to explain the monthly return variation. Exact and efficient Bayesian inference for the unknown number and positions of the breaks is performed by using filtering recursions similar to those of the forward–backward algorithm. Existing methods of testing for structural breaks are also used for comparison. We investigate the presence of structural breaks in several hedge fund indices; our results are consistent with market events and episodes that caused substantial volatility in hedge fund returns during the last decade.

In this paper we theoretically and empirically examine the interaction between hedging, financing, and investment decisions. A simple equilibrium model with costly financial distress suggests that as firms become more efficient at risky investments vis a vis low risk investments, they will borrow less, invest more in risky assets, and hedge more. The model also predicts a positive relationship between hedging and leverage – a result consistent with debt capacity arguments. We test the model empirically using a simultaneous equations framework to investigate the determinants of firm-level hedging, financing and investing decisions. The results strongly support the hypothesis that the hedging, financing and investment decisions are jointly determined. In addition, we find strong support for the central hypothesis that firms more efficient investing in risky technologies more aggressively hedge and use less debt financing in order to maximize their comparative advantage.

We are grateful to Foote and Goetz for noting that the final table of Donohue and Levitt (Quarterly Journal of Economics, 116 (2001), 379–420) inadvertently omitted state-year interactions. Correcting our mistake does not alter the sign or statistical significance of our estimates, although it does reduce their magnitude. Using a more carefully constructed measure of abortion that better links birth cohorts to abortion exposure (by using abortion data by state of residence rather than of occurrence, by adjusting for cross-state mobility, and by more precisely estimating birth years from age of arrest data), we present new evidence that abortion legalization reduces crime through both a cohort-size and a selection effect.

Using a sample of 438 firms that issued seasoned equity, we investigate the ex ante reasons stated by the firm for the use of capital, the actual ex post use of funds, and the market reaction to this information. We find that, regardless of the stated use of funds, firms increase capital expenditures and research and development following an SEO. In addition, firms increase their long term debt following an SEO, even when the stated reason for the capital is to pay down debt. The market reacts more favorably to the anticipated investment increases if the firm provides specific plans for the use of the soon-to-be-raised capital. The evidence is consistent with the view that agency issues are important factors in SEOs.
