Immigration is a possible instrument for offsetting longer-run adverse effects of population aging on per capita income. Our "laboratory" is a fictional country Alpha to which we assign demographic characteristics typical of a country experiencing population aging. Simulations indicate that a...

OBJECTIVE The paper explores the population effects of male preference stopping rules and of alternative combinations of fertility rates and male-biased birth sex ratios. METHODS The "laboratory" is a closed, stable population with five age groups and a dynamic process represented by a compact...

We explore the implications of male preference stopping rules for a stable population, and more generally the aggregate implications of higher male/female birth ratios. We begin by specifying nine alternative family stopping rules, derive their probability functions, and simulate the long-run...
