This paper examines household fertility and female labor supply over the life cycle. We investigate how maternal time inputs, market expenditures on offspring, as well as the benefits they yield their parents, vary with ages of offspring, and influence female labor supply and contraceptive behavior. Our econometric framework combines a female labor supply model and a contraceptive choice index function. It also accounts for the fact that conceptions are not perfectly controllable events. Using longitudinal data on married couples from the Panel Study of Income Dynamics, we estimate these equations and test alternative specifications of the technologies governing chld care. Our findings suggest that while parents cannot perfectly control conceptions, variations in child care costs do affect the life cycle spacing of births. Furthermore, our results demonstrate the gains of modelling the linkages between female labor supply and fertility behavior at the household level.

A specialized survey of Maine households' responses to information about the risks associate d with radon concentrations in their homes and water supplies was use d to evaluate how they form risk perceptions. The findings support a modified form of a Bayesian learning model to describe how individual s used the information to revise their risk perceptions. Moreover, in dividuals who took some mitigating actions reported lower risk percep tions after that action. The overall results are potentially importan t to the use of information programs as policy instruments for risk r eduction because they indicate that new information can affect risk p erceptions in a systematic way.

Recently, several authors have argued for the use for the use of dynamic preference structures for leisure which incorporate forms of intertemporally nonseparable utility in the analysis of intertemporal labor supply decisions. In this paper, we examine whether such nonseparable utility functions are important in characterizing microdata on life-cycle labor supply. Using longitudinal data on males from the Panel Study of Income Dynamics, we estimate a model of life-cycle labor supply and consumption under uncertainty in which the structure of intertemporal leisure preferences is allowed to be nonseparable in leisure. Our model nests as special cases a number of alternative specifications considered in the literature. We investigate the robustness of our findings to certain forms of population heterogeneity and to some types of model misspecification. Across a number of alternative specifications, we find evidence that the standard assumption of intertemporally separable preferences for leisure is not consistent with data for prime-age males.

Examined in this paper is the choice between private and public incorporation of an asset for an entrepreneur (asset owner) who hires a manager with superior information about the asset's return distribution. Public sale of equity is shown to be the preferred alternative when (a) capital market issue costs are low or (b) the assest's idiosyncratic risk is high and the owner is either sufficiently risk averse or sufficiently “optimistic” about the asset's expected return. Thus, those assets deemed most valuable by their owners will tend to be publicly incorporated. The paper also explores the impact of incorporation mode—private versus public—and information structure on the firm's investment policy and ownership distribution.
