An endogenous growth model to explain the link between equality and growth

This paper designs an endogenous growth model to explain theoretically a recently discovered empirical fact: The negative relationshlp between the growth rate of per capita GDP and the level of equality in rich countries. The main point of the model is to include equality as an argument that increases the utility of the representative agent. The model does predict a negative link between equality and growth. The intuition is as follows: more public funds devoted to social programs intended to reduce inequality may crowd out other productive activities, thus damaging per capita growth. Nonetheless, in this setting, a larger degree of equality in society may be optimal from the point of view of tbe utillty of consumers, even if it entails lower growth.
