This paper proposes a method for a multiproduct model decomposition of GDP components by expenditure which allows the use of several different price indices in the same model. The decomposition does not link the products to imports or exports, therefore, it imposes no restrictions on the...

We derive necessary and sufficient conditions for a finite data set of price and demand observations to be consistent with an additively separable preference. We do so without imposing concavity on any of the subutility functions or convexity of the budget set a priori, thereby generalizing...

We discuss and compare five measures of individual well-being, namely income, an objective composite well-being index, a measure of subjective well-being, equivalent income, and a well-being measure based on the von Neumann-Morgenstern utilities of the individuals. After examining the...
