Recent food scares in the food market has caused a reduction in consumer’s confidence in the food system that it has induced a significant reduction in consumption in a sector, the beef sector that was already characterized by a saturated trend in quantity terms. In this context, all participants in the beef production system are facing to a greatchallenge, to retrieve consumer’s confidence in the food chain and to mitigate the reduction in beef consumption. The aim of the paper is to analyse the impact of consumer’s confidence in the food system as well as other factors on the explanation of food consumption reduction. A structural modelling approach has been used to analyse factors affecting the reduction in beef consumption in two different regions characterised by different production systems and different marketing strategies (PGI beef label). Results indicate that main factor explaining the reduction in beef consumption is the confidence in the beef and a positive relation has been found. Moreover, confidence in a product is directly related to the perceived quality offered by farmers and other decision makers on the beef chain, and to the consumer involvement with the product. Therefore, the main implication is that participants in the food chain has to develop adequate communication strategies such as quality labelling in order to increase consumers perceive quality because, higher quality perception will recover consumers’ confidence in beef, and therefore, it will mitigate beef consumption reduction.

We introduce an easily implemented and flexible calibration technique for partial demand systems, combining recent developments in incomplete demand systems and a set of restrictions conditioned on the available elasticity-estimates. The technique accommodates various degrees of knowledge on cross-price elasticities, satisfies curvature restrictions, and allows the recovery of an exact welfare measure for policy analysis. The technique is illustrated with a partial demand system for food consumption in Korea for different states of knowledge on cross-price effects. The consumer welfare impact of food and agricultural trade liberalization is measured.

Previous quantitative assessments of likely impacts of recent reforms of the Common Agricultural Policy (in particular the Agenda 2000) differ across empirical studies. Differences are mainly due to the ways the policy instruments are taken into account (explicit modeling or implicit modeling i.e. using ad-valorem equivalents). The aim of this paper is to assess empirically the impacts of recent reforms of the Common Agricultural Policy and the consequences of the Mid-Term proposals on world cereals markets. We develop an econometric, dynamic, multi-product, partial equilibrium commodity model that focuses on arable crops. Major exporters and major importers are modeled separately, other countries being included in a rest of the world category. For the countries or regions explicitly integrated the model estimates supply, demand and trade. The model we develop has two important features:
i) the parameters estimated in the behavioral equations (supply and demand) satisfy regularity conditions and
ii) the agricultural policy instruments (in particular CAP instruments) are modeled in an explicit way.

In the empirical section, attention focuses on the world cereals market. We provide a market outlook through the year 2009 for three different scenarios: baseline projections and two scenarios based on different assumptions regarding the evolution of the Common Agricultural Policy (the Mid-Term Review scenario and the decoupling scenario). Estimated effects of the mid-term scenario on EU crop prices depend on the relationship between EU and world market prices.

The paper deals with problems concerning the current sugar policy within the Common Agricultural Policy, especially the efficiency losses due to the combination of high prices and quota on subsidised sugar production. Based on a simple econometric model, the total economic costs of the current policy setting, compared with an unregulated setting, are estimated to be in the area of 20 per cent of the total sugar production, valued at world market prices. Of these costs, some 10 per cent are due to inefficiency in the crop production, as the opportunity costs of land are not taken into account because the sugar price support within the quota overrules these opportunity costs. However, according to the estimates obtained in the present study, the main economic gains by reducing the internal prices are to be found in terms of reduced consumer costs rather than improved efficiency in land use.

Using a partial equilibrium model of world agriculture, we investigate the multilateral removal of all border taxes and farm programs and their distortion of world agricultural markets. These distortions have significant terms-of-trade effects. World trade is also significantly impacted by both types of distortions. Trade expansion is substantial for most commodities, especially dairy, meats, and vegetable oils. Net agricultural and food exporters (Brazil, Australia, and Argentina) emerge with expanded exports; whereas net importing countries with limited distortions before liberalization are penalized by higher world markets prices and reduced imports. The US gains significant export shares in livestock products and imports more dairy products. Without protection and domestic subsidies, the EU loses many of its livestock and dairy export markets.
