Although technical coefficients are estimated on the basis of flow data (use and make matrices), they are rarely treated as random variables. If this is done, an error term is added to the coefficients, rather than derived from the distribution of the data. Even so, the calculation of...

Neoclassical economists argue that competition promotes efficiency. They consider technology as given though. In the long run technological progress is an important determinant of the level of welfare and Schumpeter argued that monopoly rents help entrepreneurs to capture the gains of R&D and...

Multipliers measure the derivatives of endogenous variables with respect to exogenous shocks and are functions of the structural parameters of an economic model. Substitution of the structural parameter estimates yields a so-called derived estimate for a multiplier or any reduced-form parameter....

Kop Jansen and ten Raa's (1990) characterization of product-by-product input-output tables was adopted by the United Nations (1993). Recent OECD and several EU funded projects, however, used industry-by-industry tables, which raises comparable issues concerning their construction. We show how...

<b>RESUMEN</b><br> <br> Existen aportaciones recientes en las que el análisis input-output clásico se viene desarrollando con matrices de origen y destino y no con matrices de coeficientes técnicos. Sin embargo, esto no siempre es posible. Con el objetivo de construir dichas matrices de coeficientes...

An economy may perform better because the firms become more efficient, the industries are better organized, or the allocation between industries is improved. In this paper we extend the literature on the measurement of industry efficiency (a decomposition in firm contributions and an...
