This paper explores the optimal risk sharing arrangement between generations in an overlapping generations model with endogenous growth. We allow for nonseparable preferences, paying particular attention to the risk aversion of the old as well as overall "life-cycle" risk aversion. We provide a...

This paper explores the optimal risk sharing arrangement between generations in an overlapping generations model with endogenous growth. We allow for nonseparable preferences, paying particular attention to the risk aversion of the old as well as overall 'life-cycle' risk aversion. We provide a...

This chapter reviews the literature on intergenerational risk sharing (IRS). We explore to what extent and how a market economy with an appropriate institutional setting can replicate a social planner's solution in models with increasing levels of complexity. In particular, we do this for...

Using an overlapping generations model, two new indicators of public pension system sustainability are proposed: the pension space, which measures the capacity to pay for pension expenditures out of labour taxation, and the pension space exhaustion probability reflecting demographic...

This study provides a comprehensive analysis of the generational wealth transfer within Sweden's public pay-as-you-go pension system introduced in 1960. Using extensive administrative registers, the paper quantifies the contributions made and benefits received by each birth cohort. The findings...

The aging of the American population will be a critical public policy issue in the years ahead. This paper surveys the recent literature on the economics of aging, with a special emphasis on government spending on the aged. The U.S. Census Bureau projects that the proportion of the elderly in...

Poor heath, large acute and long-term care medical expenses, and spousal death are significant drivers of impoverishment among retirees. We document these facts and build a rich, overlapping generations model that reproduces them. We use the model to assess the incentive and welfare effects of...

This paper investigates the fiscal pressure from demographic change in relation to the labour marketspace for fifty countries that cover 75% of the world population. The pressure-to-space indicator ranks Poland, Turkey and Greece high. Apart from Turkey and India, developing countries rank low...

I examine if the positive correlation between wealth and survivorship has any implications for the progressivity of Social Security's current benefit-earnings rule. Using a general-equilibrium macroeconomic model calibrated to the U.S. economy, I show that the optimal benefit-earnings link for...
