We study the effects of an annuity market imperfection on individual agents' life-cycle decisions and on the macroeconomic growth rate in an overlapping generations model with single-sector endogenous growth. Our model features both age-dependent mortality and labour productivity. We model...

This paper develops and applies a simple graphical approach to portfolio selection that accounts for covariance between asset returns and an investor's labor income. Our graphical approach easily handles income shocks that are partly hedgeable, multiple risky assets, multiple risky assets, many...

This paper endogeneizes the utility penalties, initiated by Dubey, Geanakoplos and Shubik (2005), by introducing a benevolent central planner choosing the value of marginal default utility penalties for each consumer. We also prove equilibrium existence with endogenous default penalties for...

Páscoa and Seghir (2009) presented two examples to show that in the presence of utility penalties for default, collateral requirements do not always eliminate the occurrence of Ponzi schemes and equilibria may fail to exist. This paper aims at providing a counterexample to their claim. We show...

We show, by means of an example, that in models where default is subject to both collateral repossession and utility punishments, opportunities for doing Ponzi schemes are not always ruled out and (refined) equilibria may fail to exist. This is true even if default penalties are moderate as...

Pension systems often entail some compulsory saving over which individuals have some degree of choice in terms of the pension plan in which to invest. Our contribution analyses whether the choice between alternative plans is affected by the presence of liquidity constraints during working life....
