Can the Canadian Wheat Board Extract Monopoly Rents? The Case of the Spring Wheat Market

The Canadian Wheat Board (CWB) is a monopoly seller of wheat, durum and malting barley from western Canada. This paper examines the question whether the CWB monopoly can extract a premium in the international market place. Using actual transaction data (i.e. actual transaction prices) we estimate that the CWB charged importers an average price premium of $13.35/tonne for wheat over the period 1980-94. In periods when high quality wheat was in short supply the CWB was able to charge higher premiums.We also show that during the period of export subsidies the CWB earned farmers a premium by avoiding subsidized markets.
