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...

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...

Canadians are living longer and retiring younger. When combined with the aging of the baby boom generation, that means that the inactive portion of the population is increasing and there are concerns about possibly large increases in the burden of support on those who are younger. We model the...

If retirement means a substantial and sustained reduction in the time spent working for pay or profit, measurement requires a definition of substantial and sufficient observations of the same individuals to determine whether a transition from working to retired status has occurred. Using the...

We analyse a large longitudinal data file to determine who has retired and to assess how successful they are in maintaining their incomes after retirement. Our main conclusions are as follows. First, in the two years immediately after retirement the after-tax income replacement ratios average...
