Show Summary Details


It is shown that the correct way to evaluate a public project is to compare reductions in consumption arising from the investment outlay with the increase in wealth that the investment helps to create. Putting it in other words, projects should be accepted if they add to wealth, but not otherwise. It is also shown that for public projects this amounts to estimating the present discounted value (PDV) of the flow of the project's social profits. A project whose PDV is positive should be accepted; one whose PDV is negative should be rejected. The correct measure of social well‐being, even for purposes of project evaluation, is wealth. The finding unifies valuation and evaluation.

Keywords: consumption; investment; present discounted value; project evaluation; public projects; social well‐being; valuation; wealth
