This Palgrave Pivot provides a concise overview of pension systems which, whether paid by governments or by private companies, are the sole source of income for millions of people around the world. By 2050, two billion elderly people will have to be ensured some form of income while, at the same time, the prospect facing younger generations is of a gloomy future. This book breaks down the jargon, investigates different designs and analyses these designs' effects on financial sustainability, their adequacy when it comes to level and replacement rates, and their effects on intra- and inter-generational distribution. The author provides also an overview of the historical, demographic and political issues connected with the pension debate. 
This book will be of interest to students and academics, and professionals involved in the pensions industry.
