A question of interest in the demographic and actuarial fields is the estimation of the age-specific mortality pattern when data are given in age groups. Data can be provided in such a form usually because of systematic fluctuations caused by age heaping. This is a phenomenon usual to vital...

The working age population is expected to grow faster in the Middle East than in any other region in the world between now and 2015—rising annually by 2.7 percent, or 10 million people. This demographic explosion presents the region with a major challenge in terms of providing jobs, incomes,...

This paper examines how uncertainty regarding future mortality and life expectancy outcomes, i.e. longevity risk, affects employer-provided defined benefit (DB) private pension plans liabilities. The paper argues that to assess uncertainty and associated risks adequately, a stochastic approach...

This paper considers the modelling of mortality rates classified by age, time, and small area with a view to developing life table parameters relevant to assessing trends in inequalities in life chances. In particular, using a fully Bayes perspective, one may assess the stochastic variation in...

Measuring and explaining the effects of mortality changes on life expectancy has been discussed for the past three decades. Different approaches have been proposed using discrete or continuous methods. Two basic ideas underlie these approaches. The first compares two different mortality...

Se expone un procedimiento para la obtención de una tabla de mortalidad cuando no se dispone de suficiente información para su cálculo directo. Es de aplicación cuando pueden relacionarse el comportamiento seguido por una población con el de una población testigo o de referencia, en...

There are many theories of mortality, but no consensus even on the basic problem: is it genetically determined? In a general case, the problem is mathematically unsolvable. Yet, in the case of mortality, a physical approach yields its universal law. The law predicts, e.g., that mortality and...
