But the problems with those types of numbers, when you're comparing prices across countries--I don't know what statistics you have--is that a lot of them depend on what the price levels are in the country in general and on the exchange rate. You can have two different factors that can affect what goes into those.
What I would say in response to the second part of your question is that in the case of New Zealand and Australia, when their reforms took place, essentially there was a long-sighted view amongst policy-makers in those countries that there was going to be potential to export their goods in the future, and that they'd be better off to prepare themselves for those types of markets, increase their competitiveness within their country, and then try to export their goods, try to lobby, and try to reduce tariff barriers. That was exactly their notion.
The way I would rephrase my conclusion in a Canadian context is to say that the most important question facing the supply managed industry and the government, following what happens with the Doha development agenda, is really whether the supply managed system should merely realign with the new trade rules that come about, or whether or not more fundamental changes should be made to better position this sector for 2021 and beyond, which is when whatever happens at the Doha development agenda expires.
