THE DETERMINANTS OF HUMAN CAPITAL FORMATION DURING THE EARLY YEARS OF LIFE: THEORY, MEASUREMENT, AND POLICIES

In this paper, I discuss a research agenda on the study of human capital accumulation in the early years, with a particular focus on developing countries. I discuss several methodological issues, from the use of structural models, to the importance of measurement and the development of new measurement tools. I present a conceptual framework that can be used to frame the study of human capital accumulation and view the current challenges and gaps in knowledge within such an organizing structure. I provide an example of the use of such a framework to interpret the evidence on the impacts of an early years intervention based on randomized controlled trial

Effectiveness of tax incentives to boost (retirement) saving:theoretical motivation and empirical evidence

The adequacy of household saving for retirement has become a policy issue all around the world. The UK andUS have been in the vanguard of those countries that have tried to encourage retirement saving by providingtax-favoured treatment for particular savings accounts. We consider empirical evidence from these twocountries regarding the extent to which funds in some specific tax advantaged accounts (IRAs in the US,TESSAs and ISAs in the UK) represent new savings. Our best interpretation of this evidence is that: onlyrelatively small fractions of these funds can be considered to be ?new? saving and so these policies have been anexpensive means of encouraging saving; there has been some deadweight loss from the policies associated with?reshuffling? of existing savings. Continuing improvements in data on individual financial behaviour createscope for future empirical analysis of incentives to save, both within the standard economic framework that weexplain and exploit, and by considering extensions to and adaptations of it

Education choices and returns on the labor and marriage markets: Evidence from data on subjective expectations

In this paper we analyze the role of expected labor and marriage market returns as determinants of the college enrollment decisions of Mexican high school graduates. Moreover, we investigate whether the (relative) weights of these factors differ by gender. We use data on individuals’ expectations regarding future labor market outcomes which we directly elicited from the youths, and two different measures of marriage market returns. First, marriage market returns are proxied by the (net-)supply of potential partners in the youths’ local marriage markets. Second, we use data which elicits youths’ beliefs about their future spouse's earnings conditional on their own education level. We find that labor market as well as marriage market returns are important determinants of the college enrollment decision. However, boys’ and girls’ preferences differ in terms of the relative role of the two determinants, in that the relative weight of labor market versus marriage market returns is larger for boys than for girls

Efficient Responses to Targeted Cash Transfers

We estimate and test the restrictions of a collective model of household consumption, using z-conditional demands, in the context of a large conditional cash transfer program in rural Mexico. The model can explain the impacts of the program on the structure of food consumption. We use two plausible and novel distribution factors: the random allocation of a cash transfer to women and the relative size and wealth of the husband’s and wife’s family networks. Our structure does better at predicting the effect of exogenous increases in household income than an alternative, unitary, structure. We cannot reject efficiency of household decisions

Revisiting the Glick-Rogoff Current Account Model: An Application to the Current Accounts of BRICS Countries

Understanding what drives the changes in current accounts is one of the most important macroeconomic issues for developing countries. Excessive surpluses in current accounts can trigger trade wars, and excessive deficits in current accounts can, on the other hand, induce currency crises. The Glick-Rogoff (1995, Journal of Monetary Economics) model, which emphasizes productivity shocks at home and in the world, fit well with developed economies in the 1970s and 1980s. However, the Glick-Rogoff model fits poorly when it is applied to fast-growing BRICS countries for the period including the global financial crisis. We conclude that different mechanisms of current accounts work for developed and developing countries

Priority for the Worse Off and the Social Cost of Carbon

The social cost of carbon (SCC) is a monetary measure of the harms from carbon emission. Specifically, it is the reduction in current consumption that produces a loss in social welfare equivalent to that caused by the emission of a ton of CO2. The standard approach is to calculate the SCC using a discounted-utilitarian social welfare function (SWF)—one that simply adds up the well-being numbers (utilities) of individuals, as discounted by a weighting factor that decreases with time. The discounted-utilitarian SWF has been criticized both for ignoring the distribution of well-being, and for including an arbitrary preference for earlier generations. Here, we use a prioritarian SWF, with no time-discount factor, to calculate the SCC in the integrated assessment model RICE. Prioritarianism is a well-developed concept in ethics and theoretical welfare economics, but has been, thus far, little used in climate scholarship. The core idea is to give greater weight to well-being changes affecting worse off individuals. We find substantial differences between the discounted-utilitarian and non-discounted prioritarian SCC

Molecular and cellular mechanisms underlying the evolution of form and function in the amniote jaw.

The amniote jaw complex is a remarkable amalgamation of derivatives from distinct embryonic cell lineages. During development, the cells in these lineages experience concerted movements, migrations, and signaling interactions that take them from their initial origins to their final destinations and imbue their derivatives with aspects of form including their axial orientation, anatomical identity, size, and shape. Perturbations along the way can produce defects and disease, but also generate the variation necessary for jaw evolution and adaptation. We focus on molecular and cellular mechanisms that regulate form in the amniote jaw complex, and that enable structural and functional integration. Special emphasis is placed on the role of cranial neural crest mesenchyme (NCM) during the species-specific patterning of bone, cartilage, tendon, muscle, and other jaw tissues. We also address the effects of biomechanical forces during jaw development and discuss ways in which certain molecular and cellular responses add adaptive and evolutionary plasticity to jaw morphology. Overall, we highlight how variation in molecular and cellular programs can promote the phenomenal diversity and functional morphology achieved during amniote jaw evolution or lead to the range of jaw defects and disease that affect the human condition
