In an endogenous-growth model, we consider alternative ways of providi
ng public capital using distortionary taxes. We show that if the gover
nment provides the good, the resulting growth rate and welfare may or
may not be higher than under laissez-faire. By contrast, if the govern
ment subsidizes private providers, not only are growth and welfare hig
her than under public provision, they are also unambiguously higher th
an under laissez-faire. (C) 1998 Elsevier Science B.V. All rights rese
