Scale economies, returns to variety, and the productivity of public infrastructure

Article Abstract:

A model is developed to study the productivity of public infrastructure capital at general equilibrium conditions. The model assumes that public infrastructure's effect on aggregate output and manufacturing is indeterminate. On the other hand, it can change intermediate prices, factor prices and the allocation of factors across sectors. Regression estimates validate the model's assumption regarding aggregate output. However, the results also indicate a relationship between public infrastructure capital and manufacturing.
