This paper explores the role of consumption externalities in a neoclassical growth model in which households have heterogeneous preferences. We fi?nd that the degree of conformism in consumption held by each household signifi?cantly affects the speed of convergence of the aggregate economy as...

In one-sector neoclassical growth models, consumption externalities lead to an inefficient allocation in a steady state and indeterminate equilibrium toward a steady state only if there is a labor-leisure tradeoff. This paper shows that in a two-sector neoclassical growth model, even without a...

This paper introduces external habit formation into one of the basic models of endogenous growth in which continuing expansion of product variety sustains long-term growth. We assume that households consume a range of final goods and they set a benchmark level of consumption for each good. The...

One-sector neoclassical growth models reveal that consumption externalities lead to inefficient allocation in a steady state and indeterminate equilibrium toward the steady state only if there is a labor-leisure tradeoff. This paper shows that in a two-sector neoclassical growth model, even...

This paper explores the effect of consumption externalities on equilibrium dynamics of a standard neoclassical growth model in which there are two types of agents. To emphasize the presence of heterogenous agents, we distinguish intergroup consumption externalities from intragroup consumption...
