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.

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.

We analyse the competition in quality and quantity between a foreign firm and
a domestic firm. The domestic firm can belong to a certification of origin, whereas
its rival uses a pure brand strategy. We will show how the certification can allow
the domestic firm to position itself as a high quality producer and improve the
average quality of the products offered on the market. If, however, the certified
firm offers the low quality good, the certification can permit it to guarantee a
higher profit than that of its competitor and to improve the consumers’ surplus
by
favoring product standardisation.

This paper brings time series techniques to bear on the relationships between the
prices of the principal types
of wheat traded internationally. In all, the relationships between eleven wheat prices
(categorised by wheat
quality, harvest date and port of despatch) are scrutinised to uncover
the structure of the wheat market
implicit in the behaviour its prices reveal. The statistical evidence supports the
notion of a highly integrated
market that is segmented according to wheat strength . the principal determinant
of end-use. Three segments
are identified: a market for "strong" (bread-making) wheat, another for
"weak" (confectionary products-
making) wheat and a third for medium strength wheat suitable for unleavened breads
and noodles. Whilst
informative, market integration - detected by cointegration among prices . is not
altogether surprising, yet
the presence of cointegration implies a causal structure, which is of more cogent
interest. Among a number
of complementary techniques, linkages are uncovered using an innovative
concept of irreducible
cointegration vectors (Davidson 1998, Barassi et al 2001) which provides new evidence
on price linkages.
Statistical evidence is robust and not test-dependent. Specifically, we find a dominant
price leader in each
sub-market. In terms of its pricing, the EU is found to play a passive role in the
world market, confirming a
widely held view.

In this paper we present a methodology to analyse input use in the agricultural
sector. The novelty of the
theoretical model explained is that it has been developed considering a multi-criteria
environment. Thus, the
optimal input use condition is determined by the assessment of "multi-attribute utility"
and "multi-attribute
marginal utility". We show how the approach adopted in this paper is a generalization
of the single-attribute
expected utility theory. The theoretical model developed is further implemented in
an empirical application
that studies water for irrigation use as a particular case. Results show how multi-attribute
utility functions
elicited for a sample of 52 irrigators explain differences on irrigation
water use in relative homogenous
agricultural systems, albeit exhibiting similar water partial utility functions.
We conclude that these
differences come from the dissimilar weights that farmers attached to each attribute
in the aggregate utility
function. The irrigated area considered as case study is located in North-western
Spain.
