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...

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 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)....

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...

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 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...

The allocation of variable inputs among crops is a common problem in applied studies that use farm accountancy data. Standard farm accounting information is typically restricted to aggregate or whole-farm input expenditures; there are usually no details on how these expenditures are split among...

This paper aims at evaluating the impact of the 2003/2005 CAP reform on farm production choices. The outcome of “market orientation” is measured by considering both the short-term production choices and the long-term investment decisions. The Treatment Effect (TE) is estimated through recent...

Applied general equilibrium (AGE) modeling is a versatile tool for guiding public policies. However, the standard treatment of production function in AGE models is not completely satisfactory. It is commonly based on nested CES functions that are rigid and empirically hard to estimate. In this...

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...
