When equivalence scales are used to compute the well-being of individuals, two possible weighting methods of the different household types have been proposed, the first one resorts to the family size and the second to the equivalence scale itself. The latter is criticized on the ground that it...

Constructing a two-country, two-good, two-factor model of international trade under quasi-linear utility functions, we obtain a Modified Heckscher-Ohlin (MHO) Theorem that relates the trade pattern to the international distribution of factor endowments. We also show that the MHO Theorem survives...
