A mathematical programming model is developed and associated to a spatial pattern index (Ripley L-function) to analyse the optimal reserve design and implementation for the Little Bustard conservation in Plaine de Niort. The model structure corresponds to three spatial levels, fields, farm and...

Based on recent development of international economics, this paper aims to evaluate in what extent privatestandards impact trade, and more precisely trade of French agri‐food firms.Our paper explores an original "handmade" database identifying French agri‐food firms which are certified...

Grasslands received policy attention in the Czech Republic only just fifteen years ago, when they were threatened to be abandoned in the economic transition process. The supports to farming on grasslands have grown gradually, particularly after the EU accession. The policy followed the notion of...

Current thoughts on CAP changes, e.g. the "Health Check", emphasize the necessity to move away from payments based on historical receipts towards a "flatter rate" system. The aim of current research is to simulate the impact of a flat rate system (equal payments per hectare of cultivated land)...

This paper aims to provide a flexible methodological framework to estimate import demand models, which explicitly considers the stochastic properties of data and the endogenous/exogenous nature of some variables. The French imports of virgin olive oil have been used as a case study with Spain,...

For models to have an impact on policy-making, they need to be used. Exploring the relationships between policy models, model uptake and policy dynamics is the core of this article. What particular role can policy models play in the analysis and design of policies? Which factors facilitate...

A spatial price equilibrium (SPE) model of the world sugar market is programmed. The model covers more than hundred regions and contains sugar in as a sole product. It has a detailed coverage of policies and bilateral trade agreements. It is programmed as a mixed complementarity problem (MCP) in...
