Sammanfattning
AIMS: The article addresses the following
research questions: (i) How strong
is the price elasticity for beer, wine
and spirits? (ii) How rapid is the effect
of a price change? (iii) Is the price
elasticity stable across time and space?
(iv) Does an increase in price give a
corresponding effect as a decrease?
METHODS & DATA: The sales data cover Systembolaget’s
retail sales of beer, wine and spirits
for the period from January 1984 to
March 2004. The price indexes are
based on weighted baskets defl ated
by a consumer price index. Most of the
analyses were performed on quarterly
data. The data were analysed using the
Box-Jenkins technique for time series
analysis.
RESULTS: The price elasticities-as estimated
from quarterly data-were statistically
signifi cant for all beverages; -0.8 for
beer, -0.6 for wine and and -1 for
spirits. Similar estimates were obtained
from monthly data, suggesting a fast
consumer response to price changes.
The elasticity for beer was weaker
during the period 1995-2004 (-0.6) than
during the period 1984-1994 (-1.4), but
it was no different in southern Sweden
than in the remainder of the country. An
increase in the price of spirits seems
to affect sales as much as a price
decrease, that is, the price effect seemsto be symmetric. Finally, the
results indicated that since
1995 sales of beer and wine
increased more, and spirits
sales less, than predicted
from the development in
prices.
CONCLUSIONS: The study confi rms previous
fi ndings that the demand
of alcoholic beverages is
responsive to changes in
price; however, price is not
the sole factor that drives
the trends in sales. The
reduced elasticity for beer
may be due to the marked
drop in beer prices.
