This article empirically examines married women's labor supply and child care expenditures. The article uses winter 1984-85 data from the Survey of Income and Program Participation to estimate a fully structural econometric model of labor supply and paid care utilization. Estimation results indicate that the cost of paid care has small negative effects on labor supply but stronger negative effects on paid care utilization. Consequently, subsidy programs such as the Child and Dependent Care Tax Credit appear to have few effects on married mothers' employment.

This paper uses 1979-85 data on women from the National Longitudinal Survey of Youth to examine the eco-nomic, sociological, and institutional antecedents of adolescent childbearing and high school completion and to analyze the effect of early childbearing on school completion. Fertility and school completion are modeled as dichotomous outcomes, and their determinants are estimated using a bivariate probit specification. The paper finds evidence that adolescent childbearing is an endogenous determinant of high school completion and that failing to account for this endogeneity leads to an over-estimate of the schooling consequences of early childbearing.

This paper estimates economic models of the determinants of state benefit levels in the Aid to Families with Dependent Children (AFDC) program using 1969–1992 data. These models have been extensively researched; however, the existing literature has produced an unacceptably wide range of estimates. Using alternative econometric procedures, this paper systematically examines both the specification assumptions underlying previous analyses as well as several additional specification issues. It is, therefore, able to replicate and reconcile estimates from previous studies and to provide updated, consensus estimates of the demand for welfare generosity. It finds that changes in the average level of income within states have small but statistically significant positive effects on benefits with the confidence bounds on the elasticity extending from 0.11 to 0.82. Changes in the effective price of redistribution are found to have, at most, weak negative effects with elasticities in the range of -0.14 to 0.02. These results are used to evaluate the effects of block grant provisions in the recently enacted welfare reform legislation.

This study theoretically and empirically examines altruistic and joy-of-giving motivations underlying contributions to charitable activities. The theoretical analysis shows that in an economy with an infinitely large number of donors, impurely altruistic preferences lead to either asymptotically zero or complete crowd-out. The paper then establishes conditions on preferences that are sufficient to yield zero crowd-out in the limit. These conditions are fairly weak and quite plausible. An empirical representation of the model is estimated using a new 198692 panel of donations and government funding from the United States to 125 international relief and development organizations. Besides directly linking sources of public and private support, the econometric analysis controls for unobserved institution-specific factors, institution-specific changes in leadership, year-to-year changes in need, and expenditures by related organizations. The estimates show little evidence of crowd-out from either direct public or related private sources. Thus, at the margin, donations to these organizations appear to be motivated solely by joy-of-giving preferences. In addition to addressing the basic question of motives behind charitable giving, the results help explain the existing disparity between econometric and experimental crowd-out estimates.
