Competitive structure of Canadian wheat exports in the world market

摘要

This article re-examines competitive structure of Canadian wheat exporters for evidence of pricing-to-market by the Canadian Wheat Board (CWB), and extends the extant literature by utilizing a broader range of data over importing countries, which better facilitates the detection of pricing behaviour. Our analysis yields interesting empirical results that contrast with other recent arguments. In particular, we find that the CWB exercises mixed practices having market power in a limited extent, getting premiums with better quality of its wheat in some markets and providing wheat at discounted prices in some other destination countries.
