Extensions of the analysis point to the operation of a selection effect in rural-to-urban mobility but provide limited evidence for disruption effects. The possibility of further selection of urbanward...

I have illustrated that Social Security and employer-provided pension plans provide substantial incentive to leave the labor force early. The quantitative effect of this inducement is illustrated by simulating the effects of changes...

Once the men were in cohabiting unions, however, earnings had little effect on the odds of marrying. Men with better long-run socioeconomic prospects were far more likely to marry from either...

This migration effect was clearly finite in its influence, affecting only proximate vital events rather than persisting through several successive events. The temporary nature of the migration effect highlights the adaptability of international migrants. 10...

For example, if the age effect on subjective well-being is negative, an uncontrolled model could overestimate initial drops and underestimate subsequent adaptation...

Using novel weekly panel data, this analysis assesses how desires for sex may moderate the effect of the desire to avoid pregnancy on a young woman's sexual behavior and contraceptive use. Findings suggest that when a woman strongly wants to avoid pregnancy, she is less likely to have sex...
