Should Public Capital Be Subsidized or Provided?

Abstract

In an endogenous-growth model, we consider alternative ways of providing public capital using distortionary taxes. We show that if the government provides the good, the resulting growth rate and welfare may or may not be higher than under laissez-faire. By contrast, if the government subsidizes private providers, not only are growth and welfare higher than under public provision, they are also unambiguously higher than under laissez-faire.
