The life-cycle hypothesis posits that saving is positive for young households and negative for the retired, so that wealth should be hump-shaped. Yet, if one looks at the microeconomic evidence on saving by age, dissaving by the elderly is limited or absent. But the saving measures usually...

We use data from the 2009 Internet Survey of the Health and Retirement Study to examine the consumption impact of wealth shocks and unemployment during the Great Recession in the US. We find that many households experienced large capital losses in housing and in their financial portfolios, and...

This paper studies if external commitment devices are effectively capable of helping agents to reduce their consumption of addictive goods (alcohol, cigarettes, drugs, fatty foods etc.). The main assumption introduced in the model is that individuals are sophisticated hyperbolic discounters. The...

This paper introduces time inconsistent preferences into a moral hazard setting where the agent is risk-averse. We derive a necessary optimality condition on the consumption allocation that is different from the so-called Inverse Euler Equation of Rogerson (1985). Specifically, inverse marginal...

This paper studies the optimal fiscal treatment of addictive goods (cigarettes, drugs, fatty foods, alcohol, gambling etc.). It shows that, when agents have private information about their productivity levels and their degree of rationality, the Atkinson and Stiglitz result of optimal uniform...

Using life-history survey data from eleven European countries, we investigate whether childhood conditions, such as socioeconomic status, cognitive abilities and health problems influence portfolio choice and risk attitudes later in life. After controlling for the corresponding conditions in...

This paper quantifies the welfare effects of the aggregate house price collapse during the U.S. Great Recession for leveraged and un-leveraged U.S. households. We calibrate a dynamic general equilibrium model to the U.S. economy and simulate the 2007-2009 Great Recession as a contemporaneous...

Recent market developments raise doubts regarding further spread of household stock market participation. We study, computationally and econometrically, net gains from access to stocks, and estimate the potentially changing role of their determinants across the distribution of such gains for US...
