Common markets measuring price integration in european agricultural markets

Abstract

The accession of Austria, Finland and Sweden to the European Union (EU) is assessed from the perspective of market integration in key agricultural sectors. An empirical investigation is conducted using monthly data for two periods: from 1975:01-1994:12 (the pre-EU period) and 1995:01-2004:12 (post-EU period). The existence of market integration both within the countries and within the EU is tested using time-series methods. A long-run equilibrium between prices for the same good in different markets does not exclude the possibility of short-run deviations in the individual data, so part of this analysis consists of estimating an econometric model (error correction) to uncover long-run effects of price deviations. Only a subset of agricultural prices moves together after EU integration.
