The present study attempts to offer more insights into the Greek wine market with
emphasis on
wines produced from organically grown grapes by relating wine choice to consumers’
personal value
structure. With the use of a qualitative sample and applying the Means-end Chains
methodology and the
corresponding “laddering” interviewing technique, it attempts first to
reveal the way basic motives are
linked to wine shopping behaviour of consumers and the way wine purchase-relevant
knowledge is
stored and organised in their memory in relation to their personal values. Then,
by discriminating
between organic food buyers and non-buyers, the study identifies motivational and
cognitive
discriminating differences between the two consumer types, which can offer a solid
explanation as to
their distinctive purchasing behaviour in respect of the organic products.

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.

Empirical evidence suggests that agricultural futures price movements have fat-tailed
distributions and exhibit sudden and unexpected price jumps. There is also evidence
that the
volatility of futures prices contains a term structure depending on both calendar-time
and time to
maturity. This paper extends Bates (1991) jump-diffusion option pricing model by
including both
seasonal and maturity effects in volatility. An in-sample fit to market option prices
on wheat
futures shows that our model outperforms previous models considered in the literature.
A
numerical example illustrates the economic significance of our results for option
valuation.

Regional grain production in the Russian Federation has developed in a number of
different ways over the last years. The same is true for grain marketing. Not only
the prices on local markets but also those in the nation-wide grain trade seem to
be at least strongly influenced by regional authorities.
However, it is very likely that only a small part of the grain trade is exchanged interregionally. The growing independence of the Russian Federation’s political subjects seems to be primarily responsible for regional differences concerning grain production and marketing. The 1998 economic crisis is likely to obstruct the development of an efficient domestic grain market further.

This paper examines the extent of interregional integration of Russian food markets
from different perspectives. Though food price levels in Russia are converging after
the period of hyperinflation, remote regions like the Far East seem to be on a different
price path. With regard to the interregional commodity flows, it could be shown that
interregional transportation of grain is unlikely to have decreased significantly,
if the figures are corrected for imports and feed use. But a cross-sectional regression
analysis using differences between regional production and consumption revealed that
regional surpluses as well as deficits for all products tend to diminish, which means
that the Russian regions increasingly rely on their regional production and not on
interregional trade.
