I was up late last night for the results of the EU elections. In the UK, the UK Independence Party came first with 27.5% of the vote (Labour second with 25.5% and Conservatives third with 24%). In France, the Front National came first with 25%.
Both UKIP and the FN want to withdraw from the EU and reduce immigration (they differ in other respects). Since the UK is not part of the Euro, and is not likely to adopt the Euro in the near future, it is unlikely that the ECB's monetary policy had any big effect on the UK results. Neither party is fully "respectable" in the eyes of the establishment, but UKIP is more respectable than the FN.
When I first teach international trade theory, this is what I do:
I teach Comparative Advantage as an explanation of why individuals trade with each other. I then draw a circle, representing the world. I then draw lots of little dots in the circle, representing individuals. I then draw little arrows between some of the dots at random, representing gains from trade between two individuals. I then draw a horizontal line across the circle, representing the border between Canada and the US. Some of the arrows cross the horizontal line, and some of them do not. We call the former arrows "international trade". I then say it doesn't make any difference whether an arrow does or does not cross the horizontal line. Except that two different currencies will be involved if an arrow crosses the horizontal line. And governments may impose extra taxes and other restrictions on arrows that cross the line.
I don't teach the economics of migration, but if I did I might use a similar diagram, except the little arrows would now represent individuals' gaining from moving from one location to another. Some little arrows would cross the horizontal line, and some of them would not. Would it matter whether they did or did not cross the horizontal line?
Suppose you lived in a house with your family. That house is your home. Now suppose a stranger moves in, and shares the house with you. Even if that stranger paid his fair share of all the household expenses, would you always be indifferent to a stranger moving in? And if you did object, how would you feel if the rest of your family said that your objections were not respectable?
Are countries homes?
How would we do the economics of migration if we modelled countries as homes?
