This paper experimentally analyzes the schooling decisions of poor households with adolescent children in urban Brazil. Parents in our study were being paid large monthly transfers by the local government conditional upon their children attending school. We elicit parents’ incentivized choices between such conditional monthly payments and guaranteed, unconditional monthly payments of varying re...

ABC is an interactive programming language where both ease of learning and ease of use stood high amongst its principle design aims. The language is embedded in a dedicated environment that includes a structure-based editor. To fit in with the design aims, the editor had to be easy to learn, demanding a small command set, and easy to use, demanding a powerful command set and strong support for ...

This paper argues that the evolution of male preferences contributed to the dramatic increase in the proportion of working and educated women in the population over time. Male preferences evolved because some men experienced a different family model—one in which their mother was skilled and/or worked. These men, we hypothesize, were more inclined to marry women who themselves were skilled or wo...

We formulate a model of household behavior in which cooperation is costly and in which these costs vary across households. Some households rationally decide to behave noncooperatively, which in our context is an efficient outcome. An intriguing feature of the model is that, while the welfare of the spouses is continuous in the state variables, labor supply decisions are not. Small changes in st...

nowadays the phrase “social capital” has become one of the widely used general terms in social studies. the impact of social capital on economies and politics has expanded and has opened new venues for solving social and political malaise. one of the effects of social capital is its impact on personal welfare. in this article we have used a dynamic model containing two equations to study the im...

BACKGROUND Myometrial growth and remodeling of the cytoskeleton and focal adhesions during late pregnancy may be critical aspects of myometrial activation and thus labour. Yet our understanding of these aspects is inhibited by the paucity of information concerning the components of focal adhesions in the myometrium. The focal adhesion protein hydrogen peroxide-inducible clone-5 (Hic-5) has rece...

We have screened a lambda gtlO cDNA library synthesized from poly A RNA isolated from carrot somatic embryos to identify genes whose expression was associated with embryogenesis. 200,000 recombinant phage were differentially hyridized with single-stranded, 32P-labelled cDNA synthesized from poly A RNA isoalted from callus cells (1) and from embryos (2) of Daucus carota. This screen identified E...
