Yesterday, my colleague Doug Bandow blogged about Scottish independence, concluding with the following: “Whatever the Scots choose on September 18, Americans should wish them well.” I just wanted to add a quick point here, drawing on something law professor Eric Posner said on this issue: “the benefits of a large country—mainly, security and a large internal market—are of diminishing significance in a world of free trade and relative peace.”

To me, this is a very important consideration. If Scottish independence meant an increased chance of war or high tariffs designed to separate the Scottish market from the rest of the world, it would be worrying. But those seem unlikely. In terms of war and peace, there have been no Mel Gibson sightings that I’m aware of. On trade, there may be some bureaucratic challenges, but it seems clear the goal is for Scotland to join the EU and be part of its large, single market. As for trade with the rest of the world, Scotland will take on the EU’s trade policy–which is not perfect of course–but has followed the trend toward liberalization that the rest of the world has pursued over the past few decades. In all likelihood, Scotland will continue to search for export markets for its whisky and allow the free flow of imports.

If Scottish independence meant it would become like North Korea, I’d be concerned. But it doesn’t seem like that’s the path it is on. With the exception of a few regions, we live in a highly integrated, peaceful world. Scottish independence would not change that.
