We analyze the life cycle consumption choice model for multiple goods, focusing on the distinction between durables and perishables. As an approximation of the fact that rather high transaction costs and market imperfections prevail in markets for used durables, we assume that investment in...

We incorporate Keeping-up-with-the-Joneses (KUJ) preferences into the Blanchard-Yaari (BY) framework and develop, using an AK technology, a model of balanced growth. In this context we investigate status preference, demographic, and pension policy shocks. We find that a higher degree of KUJ...

Does it make us unhappier when we compare our current consumption with that of the Joneses or our own past achievements? This paper tries an answer without recurring on interpersonal utility comparisons. It calibrates an economy under three different assumptions, non-comparing utility, and...

This paper considers the quantitative role of growth in the size of the social security program in contributing to the collapse of personal saving in the U.S. over the last few decades. Using a calibrated, general equilibrium life-cycle model this paper shows that social security may not be to...

This paper studies the structure and dynamics of consumption and consumption growth inequality. The theoretical framework is a heterogeneous agent model with stochastic labor endowments, where the group mean consumption serves as consumption externality. The main finding is that households'...

This paper examines the structure and evolution of consumption and consumption growth inequality. Once heterogeneous agents relate their neighbors' consumption to their own, consumption volatility and inequality are affected. The relationship predicted between the group average consumption...

The well-documented positive correlation between income risk and wealth was interpreted as evidence for high amounts of precautionary wealth in various studies. However, the large estimates emerged from pooling non-entrepreneurs and entrepreneurs without controlling for heterogeneity. This paper...

We design an experiment to investigate the influence of announced future variations in interest rates and prices on consumption decisions. In an experimental implementation of the discounted utility model, the subjects learn the entire paths of inflation and interest rates prior to deciding on a...

Various studies have interpreted a positive correlation between income risk and wealth as evidence for large precautionary savings. However, the high estimates emerged from pooling non-entrepreneurs and entrepreneurs without controlling for heterogeneity. This paper provides evidence for Germany...

We use a realistically calibrated 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...
