Since 1999, in France, a new public intervention scheme called "CTE" has been proposed to farmers. Inside this contractual scheme, economic agents may coordinate collectively to jointly attain traditional economic objectives and environmental targets through collective projects. We are...

A dry deposition modelling approach that includes surface feedback through photosynthesis relationships was recently developed. A canopy photosynthesis model is dynamically coupled to an atmospheric model with prognostic soil hydrology and surface energy balance. The effective surface resistance...

This paper proposes planning models that will assist a flower grower with the land and flower variety allocation decisions in such a way that the revenues (or profits) are maximised over a given planning period. In particular, this paper presents models where the mix of flowers is modified...

Over the last few years, the agro food industry has been undergoing a process of accelerated change. This exploratory research analyses the strategic choices of Campania (Italy) agro food firms and focuses on competitive issues; issues that are largely affected by the mono-product nature of the...

Technical change in general milk processing is estimated within a homothetic frontier production function allowing neutrally variable scale elasticity. The results show that technical progress is characterized by a rapid increase in optimal scale and a small capital saving bias, increasing the...

This paper is concerned with the measurement of productive efficiency. Farrell's measures of efficiency are generalized to nonhomogeneous production functions. Several new measures of efficiency have been introduced and applied to the Swedish milk processing industry. The empirical analysis is...
