    Abstract: Human capital is central to efforts to promote growth, convergence, and the elimination of poverty. Drawing on the seminal macroeconomic frameworks by Nelson-Phelps, Lucas and subsequent developments, alongside macro and microeconomic evidence, we examine the role of human capital in driving innovation and growth. We highlight how different types of human capital, characterized by education level, matter in different stages of development. Despite documented increases in years of schooling, the world’s poorest regions still see stagnating outcomes in learning and education quality, potentially creating poverty traps where investments in neither physical nor human capital materialize. We discuss obstacles to human capital accumulation through a simple analytical framework and present evidence from randomized interventions spanning early childhood programs to school-age initiatives, assessing policies that can effectively remove barriers to skill acquisition and establish foundations for sustained growth.

    Abstract: Lacking lifetime income data, most intergenerational mobility estimates are subject to lifecycle bias. Using long income series from Sweden and the US, we illustrate that standard correction methods struggle to account for one important property of income processes: children from affluent families experience faster income growth, even conditional on their own characteristics. We propose a lifecycle estimator that captures this pattern and performs well across different settings. We apply the estimator to study mobility trends, including for recent cohorts that could not be considered in prior work. Despite rising income inequality, intergenerational mobility remained largely stable in both countries.

  3. By: Hamish W. Low; Costas Meghir; Luigi Pistaferri; Alessandra Voena
    Abstract: The 1996 U.S. welfare reform introduced time limits on welfare receipt. We use quasi-experimental evidence and a rich life cycle model to understand the impact of time limits on different margins of behavior and well-being. We stress the impact of marital status and marital transitions on mitigating the cost and impact of time limits. Time limits cause women to defer claiming in anticipation of future needs and to work more, effects that depend on the probabilities of marriage and divorce. They also cause an increase in employment among single mothers and reduce divorce, but their introduction costs women 0.7% of lifetime consumption, gross of the redistribution of government savings.
