Output growth decomposition of the Greek olive-oil sector under technical and allocative inefficiencies, economies of scale and technical change, is performed. The stochastic production frontier model is extended to panel data and FGLS estimation. Conventional inputs are main source of growth:...

We develop a tractable theoretical framework for analyzing the effect of advertising efficiency and spillovers on productivity growth in advertising. Maintaining the separability assumption between sales and production technology, the proposed methodology relies on sales cost function...

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 advertising spending, and the sources of total advertising productivity and sales growth....
