Premi Nobel d'Economia de l'any 2000: Una elecció encertada entre una mostra seleccionada

Abstract

The 2000 Nobel Prize in Economics was awarded to professors Heckman and McFadden for their methodological contributions in the microeconomic field, an approach concerned with econometric problems in the context of the use of information on individuals (persons, family units, business firms). The contributions of James Heckman refer fundamentally to the implications of the use of selected samples to obtain correct conclusions which can be extrapolated to the general population, a question especially relevant to analyzing models of the employment market and evaluating social programmes. The contributions of Daniel McFadden have centred on the development of models of discreet choice, their fit with the real world, their capacity to estimate and consistency as an explanatory model of the behaviour of the agents. Their contributions have important implications for the evaluation of how several economic questions affect demand for transport and residential location among others.
