In this paper we consider the implications of relative consumption externalities in the Blanchard-Yaari overlapping generations framework. Unlike most of the macroeconomic literature that studies this question, the differences between agents, and, thus, in their relative position, persist in...

We study a series of sustained growth models in which households' preferences are affected by the consumption of other households as summarized by average consumption. In endogenous growth models, the equilibrium paths involve lower savings and lower growth than the corresponding efficient...

This paper examines the impact of income growth and income inequality on household saving rates and payoffs in a non-cooperative game where each player's payoff depends on her present and future consumption and her rank in the present-consumption distribution. The setting is a pooling...

We demonstrate that interpersonal comparisons lead to "keeping up with the Joneses"-behavior. Using annual household data from the German Socio-Economic Panel, we estimate the causal effect of changes in reference consumption, defined as the consumption level of all households who are perceived...

In this paper, we first model the dynamics of an economy, making use of a simple, almost trivial circular flow analysis. Then, we demonstrate the effects of keeping up with the Jonesesʺ as well as of keeping ahead of the Smithsʺ in private consumption and the role of innovation and imitation...

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...

We analytically show that a common across rich/poor individuals Stone-Geary utility function with subsistence consumption in the context of a simple two-asset portfolio-choice model is capable of qualitatively and quantitatively explaining: (i) the higher saving rates of the rich, (ii) the...

In this study, the relation between consumer credit and real economic activity during the Great Moderation is studied in a dynamic stochastic general equilibrium model. Our model economy is populated by two different household types. Investors, who hold the economy’s capital stock, own the...

This paper studies the link between group-specific consumption growth and volatility within a framework of heterogeneous agents, under the assumption of a consumption externality. Household preferences are related to the volatility through asset holding decisions: volatility decreases with...
