Resumo(s)
Traditional approaches to calculate anal factor pmthwtivity change through Malmquist indexes rely on distance fin chaos. In this paper we show that the use of distance Junctions as a means to calculate total factor productivity change 'nth, introduce some bias in the analysis. and tnerefire tee
propose a procedure that calculates total factor productivity change through observed values only. Our total factor productivity change is then decomposed into efficiency change, technological change, and a
residual effimt. This decomposition makes use of a non-oriented measure in (E yler to avoid problems associated with the traditional use of radial oriented measures. especially when variable returns to seale
technologies are to be compared.
