Last month, the UK relatively narrowly avoided being broken up when Scotland voted 55% to 45% not to secede. Although 55% to 45% might not seem like a “narrow” win in the context of a U.S. presidential vote (and it isn’t), but when 45% of a large area of your country say they don’t want to be a part of you any more, that is not something that can be dismissed. What tipped the scales in favor of not seceding was the fear that an independent Scotland would be economically worse off. While the Scottish National Party argued that Scottish control of the North Sea oil would allow Scotland to be independent and maintain its standard of living, enough of the Scottish voters chose to stick with the “devil” they knew rather than chance independence.
Had the Scots decided to go it alone, they would have had the freedom not only devise their own economic policy but their monetary policy as well. However, England had already said that they would not allow Scotland to use the pound in the event of independence, meaning that Scotland would have had to go through the trouble of launching its own currency with a value relative to international currencies that simply couldn’t be estimated in advance. A change over from one currency to another meant that it was impossible to see when voting for/against independence how competitive Scottish goods would eventually be on international markets. This uncertainty would have been a temporary cost of economic freedom.
Another cost would have been the fact that Scotland, as a new country, would likely have found itself outside of the E.U. While the E.U. would likely welcome Scottish membership, that process of making Scotland a member of the E.U. would take time (years). In the meantime, Scottish goods would be at a disadvantage when being sold in the E.U., meaning that there would likely have been less demand for Scottish goods at any given point in time, with the concurrent drag on Scottish employment. In addition, the fact that an independent Scotland would have been outside of the E.U. initially meant that it was possible that manufactures would have tried and relocate to England (or other E.U. countries), which would not help the Scottish employment picture.
Finally, while one major selling point of independence was to get control over the bulk of the oil resources in the North Sea, revenues from this source are projected to shrink. Although the SNP was arguing that Scotland would be able to use the North Sea Oil revenues to fund a social state preferred by most Scots, it appears that this would not have been a solution long term. Scotland would have had to find a way to grow its economy (and increase its tax base), live with higher taxes and a lower overall standard of living, or see a reduced social state.
Overall, an independent Scotland would have had the freedom to do many things as a sovereign state. However, simply having the freedom to make choices is no guarantee that they would make the right ones. If they made the right choices, unencumbered from London, Scotland could have found itself with a growing economy and a higher standard of living. However, there was also a lot that could go wrong if Scotland went out on its own, leaving it worse off economically. This uncertainty and danger would have been a cost that a free and independent Scotland would have had to live with for some time.
Economic freedom is not free.
