We use a life cycle model of consumption and portfolio choice to study the effects of social security on the investment decisions of households for the European case. Our model is mainly based on the one developed by Cocco, Gomes, and Maenhout (2005). We extend it by unemployment risk using...

Rich people, women, and healthy people live longer. We document that this heterogeneity in life expectancy is large, and we use an estimated structural model to assess its effect on the elderly's saving. We find that the differences in life expectancy related to observable factors such as...

This paper constructs a rich model of saving for retired single people. Our framework allows for bequest motives and heterogeneity in medical expenses and life expectancies. We estimate the model using AHEAD data and the method of simulated moments. The data show that out-of-pocket medical...

Faced with ageing populations, OECD governments are seeking policies to increase individual retirement saving. In April 2001, the UK government introduced Stakeholder Pensions – a low cost retirement saving vehicle. The reform also changed the structure of tax-relieved contribution ceilings,...

Using three major UK pension reforms as natural experiments we investigate the relationship between pension saving and discretionary private savings. Unlike most differences-in -differences approaches which rely on average differences between the control and the treatment group, we use economic...

Job losers exhibit significant heterogeneity in wealth holdings and in the marginal propensity to consume transitory income. We consider potential sources of this heterogeneity, whether (some of) the unemployed face borrowing constraints, and the implications of this heterogeneity for...

This paper examines the effect of aid on domestic savings in Sub-Saharan Africa. It departs from the previous literature on aid and savings in developing countries by abandoning the pervasive, but untenable, assumption that all aid is used to expand the trade deficit and thus applied wholly to...

Buffer-stock versions of the dynamic stochastic optimizing model of saving are now standard in the consumption literature. This paper builds theoretical foundations for rigorous understanding of the main characteristics of buffer stock models, including the existence of a target level of wealth...

Economists working with numerical solutions to the optimal consumption/saving problem under uncertainty have long known that there are quantitatively important interactions between liquidity constraints and precautionary saving behavior This paper provides the analytical basis for those...
