We analyze the problem of optimal public investment when government purchases of productive capital assets are financed through income taxes. Virtually all previous work in this literature has prescribed a share of public investment in GDP that is both constant and time consistent. This paper...

We characterize the optimal financing of productive public capital and compute the welfare loss from being unable to commit to the Ramsey policy. Because this calculation ultimately relies on numerical approximations, we contrast alternative approaches. While perturbation and linear quadratic...
