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 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.

A modelling system is presented and used to analyse the impact of milk quota
abolishment on Dutch agriculture and economy. The modelling system consists of a
regionalised, agri-environmental, partial equilibrium, mathematical programming
model of agriculture supply in the Netherlands integrated into a mixed input-output
model. It was found that abolition of the milk quota system has large impacts on
milk
production and livestock numbers and composition. The latter is explained by the
strict mineral and manure policies in the Netherlands; an increase in the numbers
of
dairy cows leaves less room for other livestock. It is also found that, although
the total
effect on gross value added in the Dutch economy is limited, the effects for individual
industries can be large.

This study deals with horizontal product differentiation in the Polish pig meat market.
Hypothesis among firms behaviour are derived from an illustrative model and tested
in an
empirical analysis using data from 1991-1998. The empirical analysis suggest that
product
differentiation is a relevant phenomenon in the polish pig meat markets. In addition
we found
that costs and competitions are important factors influencing price variation. However,
further
influences like price discrimination and vertical product differentiation are also
important
determinants for product price variations.
