How should the government allocate its tax revenues between productivity-enhancing and utility-enhancing public goods?

We present a fairly standard general equilibrium model of endogenous growth with productive and non-productive public goods and servives. The former enhance private productivity and the latter private utility. We solve for Ramsey second-best optimal policy (where policy is summarized by the paths of the income tax rate and the allocation of the collected tax revenues between productivity-enhancing and utilityenhancing public expenditures). We show that the properties and implications of second-best optimal policy (a) differ from the benchmark case of the social planner’s first-best allocation (b) depend crucially on whether public goods and services are subject to congestion.
