| The measurement of total factor productivity in agriculture has been recently extended in order to include some 'bad' outputs that are jointly produced along with agricultural goods. In this paper, total factor productivity is decomposed into its determining factors and nitrate pollution is treated as an environmentally detrimental input. A restricted variable cost function is specified for Greek agriculture for the period 1969-1996. A constraint is assumed on nitrate pollution and the TFP estimates, which are obtained, are then decomposed into the rate of technical change effect, the scale effect and the market disequilibrium effect. |

| This paper measures the contribution of innovations in total factor productivity(TFP) of organic olive farmers. By constructing an innovation variable instead of the use of a time trend, technical change is replaced by technical difference and TFP growth becomes TFP difference. Primary cross section data on organic olive enterprises from a Greek region is used in the application of the restricted frontier profit function. Farmers are classified into groups according to their innovative ‘profile’. TFP difference among consecutive innovation groups is decomposed into technical difference and adjustment in innovativeness effects. Furthermore, efficiency differences among innovation groups are estimated. Results indicate that more innovative farmers perform... |
