Abstract

In this paper, we extend the usual models of irreversible investment underuncertainty by introducing the stock of public capital as an input for the privatesector. Public investment takes place in a stochastic environment. Public capital thenincreases the productivity of private capital which is assumed to be fully irreversible.In our model, the government has an intertemporal budget constraint, i.e. taxes arecollected each period to fund the public debt. We provide a partial equilibriumanalysis, as it is standard in models of irreversible investment under uncertainty. Evenunder uncertainty, the optimal tax rate is then constant and does not depend on thesize of uncertainty, it is exactly the same as the one that would prevail in adeterministic world. We show that the government has an insurance role since itremoves part of the uncertainty faced by the firm.
