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.

Most of the large-scale millers in Ghana provide a loan to the farmers under the
agreement that the farmers will
bring their paddy to them.
This paper examines the effect of this interlinkage on the efficiency of rice milling. A quadratic cost function was estimated, and capacity utilization was calculated in relation to money lending. The results show that if the millers provide a loan to the farmers, the operating rate will increase by 24%.

The existence and the kind of asymmetry that characterize the relationships between
shipping-point and retail prices are investigated for two major French fresh vegetables:
tomatoes
and chicory. Weekly data allow considering these relationships at very detailed levels
such as region or supermarket chain. Moreover, the methodology proposes an implicit
treatment
of asymmetries in price transmission by using recently developed threshold cointegration
methods. Our results do not give evidence to the widespread assertion that shipping-point
price increases are completely and rapidly passed by middlemen on to consumers while
there
is a slower and less complete transmission of shipping-point price declines. As already
emphasized
in the literature, these results may be linked to the perishable nature of the two
considered
fresh vegetables.

In this paper we apply the technical inefficiency effect model to a set of eight
different crop products
(i.e., wheat, mixed arable crops, tobacco, cotton, olive oil, fruits, vegetables,
and greenhouse
horticulture) in Greek agriculture.
For each product, a panel data set covering the period 1991- 1995 is used and separate econometric results are obtained for each product. A particular set of socioeconomic and demographic variables is used to explain technical efficiency differentials among Greek farmers, including the direct subsidies given to each farmer, and the concordance of these efficiency determinants is discussed across the eight different crop products considered.

The paper develops a measure of consumer welfare losses associated with withheld
information
about BSE linkage with vCJD. food safety. The Cost of Ignorance (COI) is measured
by comparing the utility of the informed choice with the utility of the uninformed
one, under condition of improved information. Unlike previous work, based on a single
equation demand model, the measure is obtained retrieving a cost function from a
dynamic Almost Ideal Demand System. The results indicate that Italian consumers bore
a significant loss because of the delayed release of information.

For many agricultural products, the quality of the final products strongly depends
on different stages
of the productive chain. This stresses the importance of relationships between quality
signal owners and
suppliers in the vertical chain. Based on a New Institutional Economics analysis,
the goal of this paper is
twofold:
(i) to design a framework to study the links between quality signaling, coordination in the supply chains and the institutional environment,
(ii) to conduct a comparative analysis to identify, compare and explain the modes of organization implemented for the governance of different quality signs.
The general hypothesis is that, in order to assure the credibility of a quality signal, there must be an efficient alignment between quality characteristics and governance of the supply chain. To test this general hypothesis, we have conducted a comparative analysis of 42 case studies in 3 sectors (processed meat, cheese, fruit and vegetable sectors) from 7 European countries. This diversity allows us to compare the organizations designed to govern different quality signals in different institutional environments and to test the matching between quality signals and governance structures.

Reductions in transport and transaction costs are expected to have a major effect
on the functioning of food
markets in developing countries. For many developing countries, this is
a relevant issue as it may have
important consequences for the food markets in urban and rural deficit areas. A partial
equilibrium model is
presented to analyze the effects of reduced costs on cereal price formation, inter-regional
cereal trade, and
farmers' and traders' storage strategies for the case of Burkina Faso. Our results
show that the high
expectations with regard to the direct effects of cost reductions on food prices
and food availability require
some nuance. First, the effects of even a huge reduction of transport costs only
will be small. Secondly, an
element which is often neglected is that constructing a road between two
cities may have unintended
negative consequences on the competitive position of farmers and traders
in other regions. Finally, it is
concluded that only if transport and transaction costs are reduced simultaneously,
both consumers and
farmers will benefit significantly.

We have employed a simple model to analyse market regulation in a situation with
multifunctional
agricultural production, i.e., a public good produced jointly with a private good,
and where there is imperfect
competition in processing. We have analysed the impact on welfare of two archetype
regulatory institutions
formed to overcome the market imperfections. The institutions, a Regulatory Marketing
Board and a
Regulatory Marketing Cooperative, are both represented in the Norwegian agricultural
market. Taking
into account the cost of public funds, we find that the Board in general ensures
the highest social welfare.
The Cooperative does not replicate the Board solution unless restricted by a price
cap and in combination
with a production subsidy. If the restricted Cooperative is able to practise a higher
degree of cost sharing than
the Board, it may however produce the highest welfare.
