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...

A simple but new theoretical approach is used to analyse ex-ante the impact of tariff reduction. This methodology is based on the assumption of a constant price relation between each direct substitutable product. No elasticities are needed, but accurate import and domestic prices of the most...

This paper illustrates the opportunities of incorporating more advanced functional forms into multi-country trade policy models. It suggests the use of flexible forms such as the Symmetric Generalized McFadden Function (SGMF) or the Normalized Quadratic-Quadratic Expenditure System (NQQES)....

The purpose of the paper is to present an agricultural supply model for Scotland used to estimate regional changes in agricultural outputs due to the 2003 Common Agricultural Policy (CAP) reform. Supply functions were estimated for several farm types based on generalised trans-logarithmic...

In this paper, the welfare results in trade liberalisation scenarios in global CGE models (like GTAP) are analysed. The default modeling strategy in trade is the Armington assumption with bilateral trade flows in industries. The negative terms of trade effects that often dominate the negative...

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,...

The methodology of construction of the alternative agricultural production scenarios at regional level includes profitability and feasibility analysis based on assessment the effect of global climate change on productivity parameters for the main agricultural crops, cost efficiency of crop...

The aim of this paper is to model some production variables in extensive livestock farms located in the dehesa ecosystem. We intend to use not only purely economic variables in the construction of the model, but also structural variables in order to identify the characteristics of the farms that...

The decoupling of direct payments, caused by the introduction of the Single Payment Scheme (SPS), has generated an incentive for farmers to decrease the production of cereals, oilseeds and protein crops (COP) and (because of the reform of sugar CMO) sugar beet. In some cases, this has also...
