“…There is corroborating evidence, by economists Steven Globerman and Paul Storer, (Globerman and Storer, 2004) of a failure of price convergence between Canada and the United States, which might suggest that the border is still a significant trade barrier (although these authors stress that it is volatility in the exchange rate which accounts for most of the non-convergence). This obliquely raises yet another deep integration issue: movement to a common currency (or outright "dollarization" in Canada), which we d o not pursue at length here, except to point out that there is much debate among Canadian academics, although notably not much among policy-makers, of the costs and benefits to Canada of monetary integration with the United States."…”
