Population aging is a problem common to many countries: an increasing proportion of retired people, a decreasing proportion of working age, and resultant downward pressure on national product per capita. We explore longer-run aspects of immigration as a policy instrument in this context. We...

[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...

[Background:] Surveys of chronic health conditions provide information about prevalence but not about the incidence and the process of change within the population. [Objective:] We show how the "age dynamics" of chronic conditions - the probabilities of contracting the conditions at different...

The paper considers age-sex patterns of fluctuation of employment, unemployment, labour force participation, hours worked per employee, and hours worked per capita. The patterns are extracted (by regression) from annual data for the period 1976-2011 and expressed in the form of...

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...

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...

Immigrants can mix with the population of a receiving country in various ways. We consider demographic mixing by which we mean cross-mating, and more particularly the bearing of children where one parent is of immigrant descent and the other is not - cross-parenting as we term it. We consider a...

A shift in population distribution toward older ages is underway in industrialised countries throughout the world and will continue well into the future. We provide a framework for isolating the pure effects of population aging on per capita GDP, employ the framework in calculations for twenty...

Since the concept of retirement is prominent in both popular thinking and academic studies it would be helpful if the notion were analytically sound, could be measured with precision, and would make possible comparisons of patterns of retirement over time and among different populations. This...

We derive transition probability matrices for chronic health conditions using survey prevalence data. Matrices are constructed for successive age groups and the sequence represents the age dynamics of the health conditions for a stationary population - the probabilities of acquiring the...
