This paper proposes a tractable approach for analyzing the sources of TFP changes (i.e., technical change, changes in technical and allocative inefficiency, and the scale effect) in a multi-output setting, while retaining the single-equation nature of the econometric procedure used to estimate the parameters of the underlying technology. The proposed… (More)

An alternative version of decomposition analysis, based on factor cost shares rather than input demand functions, is presented and applied to Greek agriculture. Decomposition analysis shows that most of the changes in factor cost shares during the period from 1973 to 1989 are attributed to technical change and factor substitution, while the role of the… (More)
Introduction Most of cross country studies on research productivity differences do not take into account compositional differences in academic staff force, such as sex, years of experience, origin of PhD studies, even though there are well documented evidence that (a) males tend to publish more than females (Gupta et al., 1999); (b) junior academic staff… (More)

Abstract This paper develops a tractable theoretical framework for analyzing the substitutability between different advertising media, the extent of marketing spillovers in the market, the allocative efficiency of… (More)
