Econometric models wishing to estimate relevant parameters for agricultural policy analysis are increasingly relying on unbalanced panels of farm-level data. Since in the agricultural economics literature such models have often been estimated through simplified approaches, in this paper we try...

We derive a (quadratic) inverse demand system (IQUAIDS), that generalizes the (almost ideal) inverse demand system. We discuss how the assumptions of separability and concavity can be simultaneously accommodated within the model, thus giving a (locally) separable and concave quadratic demand...

Micro-econometric demand modelling has been receiving an increasing attention in empirical research, mainly due to the increasing availability of micro-data. In this paper we provide a review of some relevant market and policy issues that can be analysed with the use of micro-data on demand....

The paper reviews the econometric models used in the past 10 years to analyse the most widely used agricultural policy instruments. The main aim of the paper is to provide the reader with an overview of these models, analysing the technical solutions adopted, the type of results that can be...

In this paper we develop a new methodological proposal to incorporate risk into a farm level Positive Mathematical Programming (PMP) model. Our model presents some innovations with respect to the previous literature and estimates simultaneously the resource shadow prices, the farm non-linear...
