The impact of current nitrate policy measures in Flanders is estimated. A modular modelling system has been developed for comparing response and pressure indicators and for decomposing the response impact of policy measures. Compared to 1990, the internalised manure surplus is reduced to zero,...

The price-wedge method yields a tariff-equivalent estimate of technical barriers to trade (TBT). An extension of this method accounts for imperfect substitution between domestic and imported goods and incorporates recent findings on trade costs. We explore the sensitivity of this revamped tariff...

It is well documented that consumers tend to be patriotic in their choices of food. This paper theoretically examines the consequences of such patriotic behavior for agricultural policy, assuming that the policy is decided by the median voter. The analysis is conducted in the framework of a...

This paper presents the application of the sensitivity analysis techniques Design of Experiments (DOE) and metamodelling to the agent-based model AgriPoliS, which is a spatial and dynamic simulation model of regional structural change. DOE and metamodelling provide a more systematic analysis of...

In developed countries governments aim to increase the market share of organic products. Assuming that organic farming creates a positive externality, we address the question of how this environmental benefit can be internalized best. Using the concept of heterogeneous producers and consumers we...

The food processing industry in Western countries operates in markets that usually are highly concentrated, consisting of a few cooperatives and investor-owned firms. However, in the literature some studies questioned whether the mixed market structure is a stable equilibrium, and suggestions...

ACRE is an Agro-eConomic model for agricultural pRoduction on rEgional level. Based on an extension of Positive Mathematical Programming (PMP) this model was developed as a decision tool for politics with respect to questions of global change scenarios. The validity of the theoretical approach...

This paper attempts to estimate energy crop supply using an LP model comprising hundreds of representative farms of the arable cropping sector in France. In order to enhance the predictive ability of such a model and to provide an analytical tool useful to policy makers, interval linear...

Our optimal control model identifies economic reasons as to why farmland bird populations have dramatically declined in modern agricultural landscapes. By integrating recreational wildlife values into farm level decision-making on arable crop choice and herbicide use, we derive those economic...
