More mothers engage in marketplace work today than ever before, with over 33% returning to work by the time their child is 3 months old. This article identifies the effects of maternal marketplace work in the initial months of an infant’s life on the child's cognitive development. Results suggest that such work in the first year of a child’s life has detrimental effects. Where significant, the results also indicate negative effects of maternal employment in the child’s first quarter of life. However, the negative effects of maternal marketplace work are partially offset by positive effects of increased family income.

This paper tests two theories of corporate investment myopia which predict a distortion in investment policy with respect to the standard net present value rule. The theories are confronted with the empirical evidence, allowing the theories to compete to explain investment behavior. Research and development expense is used to proxy for long-term investment in a pooled, cross-sectional time-series regression. I find that research and development expense is decreasing in the age of the Chief Executive Officer. Results are consistent with the hypothesis that agency costs are lower when the firm invests myopically, rather than follow a standard net present value rule.

This paper provides a framework and some empirical evidence to evaluate the seriousness of problems in inference that arise in stockreturn-based studies when the data are cross-sectionally dependent. The study is motivated on the grounds that statistical procedures designed to address such problems are often infeasible, and even when they can be implemented they sometimes introduce other more serious difficulties. Thus, researchers have frequently adopted an approach that ignores the cross-sectional dependence (e.g., ordinary least squares [OLS]). The objective of this paper is to help identify the contexts in which ignoring the dependence would lead to serious misstatement of significance levels. Cross-sectional dependence in stock returns data is likely to exist when at least some of the returns are sampled from common time periods. This would be the case in all studies of the reaction of stock prices to a

This paper examines the use of alternative information sets in the construction of inflation hedge portfolios. The study is motivated by consideration of the investor's problem in a multiperiod world. Several authors (e.g., Merton [1973] and Breeden [1979]) have shown that in a multiperiod setting, optimal investment behavior will, in general, involve holding portfolios that can be used to hedge against changes in certain relevant states of nature. One potentially relevant state of nature is the rate of inflation in general prices (Jones [1982] and Elton, Gruber, and Rentzler [1983]). In contrast to prior related research, the empirical results indicate that it is possible to construct inflation hedge portfolios successfully, if certain accounting information is used. However, portfolios constructed on the basis of historical security price information do not serve as effective hedges. One contribution of this paper is to demonstrate the potential usefulness of accounting information to a price-taking investor. Although financial statements play an important role in the setting of equilibrium
