Recent research has found that maternal employment is associated with worse child performance on tests of cognitive ability. This paper explores mechanisms for that correlation. We estimate models of instrumental variables using a unique dataset, the American Time Use Survey, that measure the...

In this paper we compare the educational attainment of birth and non-birth children of women in the Panel Study of Income Dynamics (PSID). We find that children raised by step, adoptive or foster mothers obtain significantly less education on average than do the birth children of the same women....

Charter schools have become a very popular instrument for reforming public schools, because they expand choices, facilitate local innovation, and provide incentives for the regular public schools while remaining under public control. Despite their conceptual appeal, evaluating their performance...

Growth theory can go a long way toward accounting for phenomena linked with U.S. economic development. Some examples are: (i) the secular decline in fertility between 1800 and 1980, (ii) the decline in agricultural employment and the rise in skill since 1800, (iii) the demise of child labor...

Women's empowerment and economic development are closely related: in one direction, development alone can play a major role in driving down inequality between men and women; in the other direction, empowering women may benefit development. Does this imply that pushing just one of these two...

This paper studies the impact of female property rights on male and female suicide rates in India. Using state level variation in legal changes to women's property rights, we show that better property rights for women are associated with a decrease in the difference between female and male...

Living arrangements have changed enormously over the last two centuries. While the average American today lives in a household of only three people, in 1850 household size was twice that figure. Further, both the number of children and the number of adults in a household have fallen...

In the past two decades China leaped from bit player in global science and engineering (S&E) to become the world's largest source of S&E graduates and the second largest spender on R&D and second largest producer of scientific papers. As a latecomer to modern science and engineering, China...

This paper investigates, theoretically and empirically, a possibly fundamental aspect of technological progress. If knowledge accumulates as technology progresses, then successive generations of innovators may face an increasing educational burden. Innovators can compensate in their education by...

Great achievements in knowledge are produced by older innovators today than they were a century ago. Using data on Nobel Prize winners and great inventors, I find that the age at which noted innovations are produced has increased by approximately 6 years over the 20th Century. This trend is...
