Abstract:
... We estimate the impact of removing an export subsidy on the local economies of Alberta, Saskatchewan and Manitoba, exploiting the large regional variation of a 1995 reform. We find that the loss of the subsidy resulted in significantly lower farm value‐added, farm asset values and local non‐farm employment. The results suggest that the subsidy removal had detrimental spillover effects on the local ...

Abstract:
... We examine the effect of wheat stocks on the relationship between port and inland wheat prices in western Canada after the dissolution of the Canadian Wheat Board in 2012. Standard statistical tests find no evidence that the port price is cointegrated with inland prices. We argue that large harvests in 2013–2014 and 2014–2015 are responsible for this lack of cointegration. A simple theoretical mod ...
