The comparative advantages of the rape-seed production were quantified by policy analysis matrices (PAM). Analysis was conducted on the data of selected agricultural cooperatives located in different growing conditions. The indicators DRC, CC, NEB, IVA of relative comparative advantages were derived from the results of PAM. Comparative static compensated PAM disadvantages, namely static concept and data availability (1997 only). Scenarios were based on world price decrease expectations, the influence of exchange rate policy and abolishment of subsidies. Under these conditions, a loss of comparative advantages of the rape-seed production was observed in agricultural cooperative.
