This paper considers a model with nonlinear income taxation and public good provision when people care about their relative consumption compared to others. The standard optimality expressions are modified by terms that reflect the extent to which people care about relative consumption. The...

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 investigates household decisions in an overlapping generations model in which individual utility depends on a weighted average of consumption of one's peers. In contrast to representative agent economies, the consumption externality generally affects savings and growth rates. The...

We analyze the effects of a generalized class of negative consumption externalities (asymmetric and non-atmospheric) on the structure of efficient commodity tax programs. Households are not only concerned about consumption reference levels — that is, they gain utility from “keeping up with...

We investigate the role of anonymity, reciprocity, and conformity for voluntary contributions, based on a natural field experiment conducted at a national park in Costa Rica. Contributions made in public in front of the solicitor are 25% higher than contributions made in private. Giving subjects...

We measure people's pro-social behavior, in terms of voluntary money and labor contributions to an archetypical public good, a bridge, and in terms of voluntary money contributions in a public good game, using the same non-student sample in rural Vietnam at four different points in time from...

Following the 1987 report by The World Commission on Environment and Development, the genuine saving has come to play a key role in the context of sustainable development, and the World Bank regularly publishes numbers for genuine saving on a national basis. However, these numbers are typically...
