Abstract

We investigate partial insurance and group risk sharing in extended family networks. Our approach is based on decomposing income shocks into group aggregate and idiosyncratic components, allowing us to measure the extent to which each is insured, having accounted for public insurance programs. We apply our framework to extended family networks in the United States by exploiting the unique intergenerational structure of the PSID. We find that over 60% of shocks to household income are potentially insurable within family networks. However, we find little evidence that the extended family provides insurance for such idiosyncratic shocks.

Abstract

We develop an equilibrium life cycle model of education, marriage and labor supply and consumption in a transferable utility context. Individuals start by choosing their investments in education anticipating returns in the marriage market and the labor market. They then match based on the economic value of marriage and on preferences. Equilibrium in the marriage market determines intrahousehold allocation of resources. Following marriage households (married or single) save, supply labor and consume private and public commodities under uncertainty. Marriage thus has the dual role of providing public goods and offering risk sharing. The model is estimated using the British HPS.

Abstract

We examine the channels through which a randomized early childhood intervention in Colombia led to significant gains in cognitive and socio-emotional skills among a sample of disadvantaged children aged 12 to 24 months at baseline. We estimate the determinants of parents’ material and time investments in these children and evaluate the impact of the treatment on such investments. We then estimate the production functions for cognitive and socio-emotional skills. The effects of the program can be explained by increases in parental investments, emphasizing the importance of parenting interventions at an early age.

Abstract

We examine the channels through which a randomized early childhood intervention in Colombia led to significant gains in cognitive and socio-emotional skills among a sample of disadvantaged children. We estimate production functions for cognitive and socio-emotional skills as a function of maternal skills and child’s past skills, as well as material and time investments that are treated as endogenous. The effects of the program can be fully explained by increases in parental investments, which have strong effects on outcomes and are complementary to both maternal skills and child’s past skills.

Abstract

In this paper we develop an approach to measuring inequality and poverty that recognizes the fact that individuals within households may have both different preferences and differential access to resources. We argue that a measure based on estimates of the sharing rule is inadequate as an approach that seeks to understand how welfare is distributed in the population because it ignores public good and the allocation of time to market work, leisure and household production. We develop a money metric measure of welfare that accounts for public goods (by using personalized prices) household production and for the allocation of time.

Abstract

Studies of inequality often ignore resource allocation within the household. In doing so they miss an important element of the distribution of welfare that can vary dramatically depending on overall environmental and economic factors. Thus, measures of inequality that ignore intra household allocations are both incomplete and misleading. We discuss determinants of intra household allocation of resources and welfare. We show how the sharing rule, which characterizes the within household allocations, can be identified from data on household consumption and labor supply. We also argue that a measure based on estimates of the sharing rule is inadequate as an approach that seeks to understand how welfare is distributed in the population because it ignores public goods and the allocation of time to market work, leisure and household production. We discuss a money metric alternative, that fully characterizes the utility level reached by the agent. We then review the current literature on the estimation of the sharing rule based on a number of approaches, including the use of distribution factors as well as preference restrictions.

Abstract

We estimate a dynamic model of employment, human capital accumulation — including education, and savings for women in the UK, exploiting policy changes. We analyze both the incentive effects and the welfare implications of tax credits and income support programs and we account for their insurance value. We find important incentive effects on education choice and labor supply, with single mothers having the most elastic labor supply. Returns to experience increase with education, but experience only accumulates when in full-time employment. Finally, marginal increases in tax credits are preferred to equally costly income support or to tax cuts.

Abstract

We consider the impact of Tax credits and income support programs on female education choice, employment, hours and human capital accumulation over the life-cycle. We thus analyze both the short run incentive effects and the longer run implications of such programs. By allowing for risk aversion and savings we are also able to quantify the insurance value of alternative programs. We find important incentive effects on education choice, and labor supply, with single mothers having the most elastic labor supply. Returns to labour market experience are found to be substantial but only for full-time employment, and especially for women with more than basic formal education. For those with lower education the welfare programs are shown to have substantial insurance value. Based on the model marginal increases to tax credits are preferred to equally costly increases in income support and to tax cuts, except by those in the highest education group.

Abstract

We estimate a dynamic model of employment, human capital accumulation - including education, and savings for women in the UK, exploiting tax and benefit reforms, and use it to analyze the effects of welfare policy. We find substantial elasticities for labor supply and particularly for lone mothers. Returns to experience, which are important in determining the longer-term effects of policy, increase with education, but experience mainly accumulates when in full-time employment. Tax credits are welfare improving in the UK and increase lone-mother labor supply, but the employment effects do not extend beyond the period of eligibility. Marginal increases in tax credits improve welfare more than equally costly increases in income support or tax cuts.
