We show that task juggling, i.e., the spreading of effort across too many active projects, decreases the performance of workers, raising the chances of low throughput, long duration of projects and exploding backlogs. Individual speed of job completion cannot be explained only in terms of...

To analyze the effect of health on work, many studies use a simple self-assessed health measure based upon a question such as "do you have an impairment or health problem limiting the kind or amount of work you can do?" A possible drawback of such a measure is the possibility that different...

We explore the impact on depressive symptoms of deviation in actual labor force behavior at age 62 from earlier expectations. Our sample of 4,241 observations is drawn from the Health and Retirement Study (HRS). We examine workers who were less than 62 years of age at the 1992 HRS baseline, and...

Powerful currents have reshaped the structure of families over the last century. There has been (i) a dramatic drop in fertility and greater parental investment in children; (ii) a rise in married female labor-force participation; (iii) a significant decline in marriage and a rise in divorce; (iv)...

We examine a determinant of cultural persistence that has emerged from a class of models in evolutionary anthropology: the similarity of the environment across generations. Within these models, when the environment is more similar across generations, the traits that have evolved up to the...

The last few decades witnessed a dramatic change in public opinion towards gay people. This paper studies the hypothesis that the AIDS epidemic was a shock that changed the incentive to “come out” and that the ensuing process of mobilization and endogenous political process led to cultural...

This paper reviews the evidence regarding the main trends in the height of the British population since the early eighteenth century. We argue that the average heights of successive birth cohorts of British males increased slowly between the middle of the eighteenth century and the first quarter...

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...

This paper discusses the problems facing the Mexican economy. It operates under a heavy burden of monopoly and regulation. We focus on two issues that should receive more attention in discussions of Mexican policy. (1) The family is under stress in Mexico and this retards the growth of skills of...

Europeans restricted their fertility long before the Demographic Transition. By raising the marriage age of women and ensuring that a substantial proportion remained celibate, the "European Marriage Pattern" (EMP) reduced childbirths by up to one third between the 14th and 18th century. In a...
