Endogenous Growth In A Model With Heterogeneous Agents And Voting On Public Goods
The authors consider a Barro-type endogenous growth model in which the government's purchases of goods and services enter into the production function. The provision of government services is financed by flat-rate (linear) income or lump-sum taxes. It is assumed that individuals differing in their discount factors vote on the tax rates. They propose a concept of voting equilibrium leading to some versions of the median voter theorem for steady-state equilibria, fully characterize steady-state equilibria and show that if the median voter discount factor is sufficiently low, the long-run rate of growth in the case of flat-rate income taxation is higher than that in the case of lump-sum taxation.
