If A is a set of social alternatives, a social choice rule (SCR) assigns a subset of A to each potential profile of individuals' preferences over A, where the subset is interpreted as the set of "welfare optima". A game form (or "mechanism") implements the social choice rule if, for any...

For guidance in determining which items should be included in comprehensive NDP and how they should be included, reference is often made to the linearized Hamiltonian from an optimal growth problem. The paper gives a rigorous interpretation of this procedure in terms of a money-metric utility...

Using only information based on currently-observable market behavior, the paper shows how to make rigorous dynamic welfare comparisons among economies or economic situations having arbitrarily-different endowments and technologies,but sharing a common dynamic preference ordering. The correct...

For guidance in determining which items should be included in comprehensive NDP and how they should be included, reference is often made to the libearized Hamiltonian from an optimal growth problem. This note shows how the heuristic linearized-Hamiltonian argumentcan be given a rigorous welfare...

"Green NNP" is a national accounting concept that substracts off from GNP not just depreciation of capital, but also depletion of environmental assets evaluated at competitive of efficiency prices. Recent literature shows that, for a time-autonomous technology, Green NNP has regorous welfare...
