A Welfare Decomposition in Quasi-Linear Economies

No 569, Boston College Working Papers in Economics from Boston College Department of Economics

Abstract: We propose a decomposition of social welfare when consumers' preferences are described by quasi-linear utility functions. In our decomposition, social welfare is expressed as the sum of consumers' gross utilities and trade surplus of non-numeraire goods, whose consumption enters utility functions non-linearly. This decomposition is useful especially when we assess the impact of trade liberalization on individual countries.
