Population ageing and pension reform will have profound effects on international capital markets. First, population ageing alters the time path of aggregate savings within individual countries. Second, this process may be amplifi ed when a pension reform shifts old-age provision towards more pre-funding. Third, while the patterns of population ageing are similar in most countries, timing and in...

The population of Kosrae has changed dramatically since its first contact with non-Micronesian societies nearly two hundred years ago. Some of the greatest changes occurred during the nineteenth century, when diseases introduced by outsiders nearly eradicated the native population. More recently the number of Kosrae residents has grown, the rapid increases during the twentieth century producing...

The northern bobwhite (Colinus virginianus) is an economically important gamebird that is currently undergoing widespread population declines. Despite considerable research on the population ecology of bobwhites, there have been few attempts to model population dynamics of bobwhites to determine the contributions of different demographic parameters to variance of the finite rate of population c...

The polar bear (Ursus maritimus) depends on sea ice for feeding, breeding, and movement. Significant reductions in Arctic sea ice are forecast to continue because of climate warming. We evaluated the impacts of climate change on polar bears in the southern Beaufort Sea by means of a demographic analysis, combining deterministic, stochastic, environment-dependent matrix population models with fo...

Classic studies on local demographic consequences of natural disasters in the United States are now more than 30 years old, raising questions about how and to what extent relevant patterns have changed over intervening years, as the number and cost of recorded environmental hazards have increased. This study examines these questions at the county level for the nation as a whole, using recent ce...

The paper analyzes an economy with an agrarian and an industrial sector. Demand is determined by Engel's Law. Population growth follows a non{linear income dependent path according to the theory of demographic transition. In case of decreasing returns to scale in the agrarian sector the existence of a stable low{income equilibrium with high population growth can be shown. If this equilibrium is...
