This paper analyzes the optimal consumption behavior of a consumer who faces uninsurable labor income risk and borrowing constraints. In particular, it provides conditions under which the decision rule for consumption is a concave function of existing assets. The current study presents two main...

Eusepi (2009, International Journal of Economic Theory 5, pp. 9-23) analytically finds that a one-sector real business cycle model may exhibit positive co-movement between consumption and investment when the equilibrium wage-hours locus is positively-sloped and steeper than the household's labor...

This paper presents a dynamic competitive equilibrium model in which heterogeneity in time preferences alone can generate the observed patterns of wealth and income inequality in the United States. This model generalizes the standard deterministic neoclassical growth model by introducing (i) a...

This paper examines the theoretical foundations of precautionary wealth accumulation in a multi-period model where consumers face uninsurable earnings risk and borrowing constraints. We begin by characterizing the consumption function of individual consumers. We show that consumption function is...

This paper analyzes the connection between time preference heterogeneity and economic inequality. To achieve this, we extend the standard neoclassical growth model by introducing three additional features, namely (i) heterogeneity in consumers' discount rates, (ii) direct preferences for wealth,...

This paper examines the connection between time preference heterogeneity and economic inequality in a deterministic environment. Specifically, we extend the standard neoclassical growth model by introducing three additional features, namely (i) heterogeneity in consumers' discount rates, (ii)...

This paper re-examines the conditions under which endogenous economic growth can emerge in neoclassical models with non-renewable resources. Unlike most of the existing studies which focus exclusively on Cobb-Douglas production function, our analysis is based on a general specification. We...

This paper analyzes the risk attitude and investment behavior of a group of heterogeneous consumers who face an undesirable background risk. It is shown that standard risk aversion at the individual level does not imply standard risk aversion at the group level under efficient risk sharing. This...

Is a more heterogeneous population beneficial or harmful to long-term economic performance? This paper addresses this and other questions in a dynamic general equilibrium model where consumers have different labour productivity and time preference. We show how differences in the cross-sectional...

This paper analyzes the risk attitude and investment behavior of a group of heterogeneous consumers who face an uninsurable background risk. It is shown that standard risk aversion at the individual level does not imply standard risk aversion at the group level under efficient risk sharing. This...
