Social scientists theorize that the inverse relationship between socio-economic status and family size represents a trade-off between the quality and quantity of children. Evaluating this hypothesis empirically requires addressing the simultaneity of the quality and quantity decisions....

Exploiting recent concentration of flight patterns under a new Federal Aviation Administration policy (called NextGen), we examine the impact of exposure to excessive noise levels on birth outcomes. Using birth records that include mothers' home addresses to measure airport proximity, we find...
