This paper derives necessary and sufficient conditions under which positional preferences do not induce inter-temporal distortions. When labor supply is exogenous, positional preferences for consumption have been shown to be non-distortionary for a class of models. However, it has not been...

This paper investigates household decisions, and optimal taxation in an overlapping generations model in which individual utility depends on a weighted average of consumption of ones peers --- a ``keeping up with the Joneses'' consumption externality. In contrast to representative agent...

This paper analyzes the effects of non-atmospheric consumption externalities on optimal commodity taxation and on the social cost and optimal levels of public good provision. A negative consumption externality, by lowering the social cost of public good provision, may require the second-best...

This paper investigates household decisions when individual utility depends on a consumption reference level. The desire to ``keep up with the Joneses'' represents one such example. The prior literature shows that, in a Ramsey model, consumption externalities have no impact on steady state...

Most studies of the optimal provision of public goods or the excess burden from taxation assume that individual utility is independent of other individuals' consumption. This paper investigates public good provision and excess burden in a model that allows for interdependence in consumption in...

This paper analyzes the impact of consumption externalities on the ``Pigouvian ranking,'' according to which the second-best level of public good provision is \emph{smaller} than the first-best level. Consumption externalities introduce exceptions to the Pigouvian ranking. Two necessary and...

This paper investigates the effects of (``keeping up with the Joneses'' and ``learning-by-investing'') externalities, when labor productivity decreases with age. Within the framework of a continuous time overlapping generations model, the effects of the consumption externality on the propensity...

This paper investigates the impact of externalities on economic growth in an AK model. In contrast to the existing literature, the paper considers finitely-lived agents along the continuous time, overlapping generations literature. A series of new results, not holding for infinitely-lived agent...

This paper investigates the impact of the desire to keep up with the Joneses (KUJ) on economic growth and optimal tax policy in a continuous time overlapping generations model with AK technology and gradual retirement. Due to the desire to KUJ, the propensity to consume out of total wealth rises...

This paper sets up a dynamic general equilibrium model to study how the composition of technical progress affects the asymptotic speed of convergence. The following questions are addressed: Will endogenizing a fraction of the productivity increases as coming from learning by investing help to...
