Politics muddies the waters of Scotland and the pound

It's simple, until it's not.

Simon Wren-Lewis digests the Treasury's report on the relationship an independent Scotland would have with sterling and the Bank of England (rUK is his shorthand for the UK excluding Scotland):

The real problem for Scotland is that, in forming a sterling currency union, it will be dealing with a government that thinks like Germany. What is worse, although Germany can sometimes be persuaded to go against its austerity instincts for the sake of European unity, after an independence vote rUK is unlikely to let its heart strings be pulled in a similar way! The problem for Scotland is that the rUK can provide something that in fact costs it very little, but the absence of which would cost Scotland a great deal, so rUK will be able to ask for a high price. Unless the new Scottish government is prepared to pay for a Bank of England LOLR role with some of its oil revenues, it may find it has nothing to bargain with. If no agreement can be found, the Treasury paper is quite right to conclude that using sterling unilaterally would not be attractive for Scotland. So rather than accept damaging fiscal restrictions, the new Scottish government may end up with its own currency after all.

George Osborne is right to present the Treasury's analysis as a stumbling block for the SNP, in other words; but he's slightly disingenuous in pretending that he has nothing to do with that fact.

As Wren-Lewis points out, politics muddies all waters. Normally, the study of Optimal Currency Areas is relatively simple: the more alike two countries are, the greater the benefits of having a shared currency, and the lesser the disbenefits. That's why the euro is such a startlingly bad idea on paper – there's basically no possible group of countries less economically, socially and politically coherent than the eurozone. And in in nations like rUK and Scotland, which are pretty damn similar, the whole deal comes down to one basic question: is the loss of flexibility of monetary policy a worthwhile cost to pay for those benefits?

But that assumes that there is any way a currency union between rUK and Scotland could actually exist as a union. It's a political, not an economic question: what possible scenarios can we imagine in which the Bank of England would view the Scottish economy as anything other than entirely subordinate to the interests of rUK's? And, moreover, what possible scenarios can we imagine in which an actually existing rUK government – as short-termist, economically-illiterate and vindictive as they tend to be – would allow that to happen?

It may just be the case that the rUK would be better off if the Bank of England carried its policy equitably, allowing the rUK to take a hit to ensure the continued strength of Scotland, which would be on of its biggest, if not the biggest, trading partner. But it's nigh-on impossible to imagine a rUK government letting the Bank of England incorporate that rationalisation into its mandate.

Compared to questions of fair allocation of public debt, North Sea Oil and monarchs (Scotland can have em, frankly), the question of Scottish monetary policy might seem boringly technical. But it's one of the most intractable problems standing in the way of Alex Salmond's dream.

Donald Trump vs Barack Obama: How the inauguration speeches compared

We compared the two presidents on trade, foreign affairs and climate change – so you (really, really) don't have to.

After watching Donald Trump's inaugural address, what better way to get rid of the last few dregs of hope than by comparing what he said with Barack Obama's address from 2009? 

Both thanked the previous President, with Trump calling the Obamas "magnificent", and pledged to reform Washington, but the comparison ended there. 

Here is what each of them said: 

On American jobs

Obama:

The state of our economy calls for action, bold and swift.  And we will act, not only to create new jobs, but to lay a new foundation for growth.  We will build the roads and bridges, the electric grids and digital lines that feed our commerce and bind us together.  We'll restore science to its rightful place, and wield technology's wonders to raise health care's quality and lower its cost.  We will harness the sun and the winds and the soil to fuel our cars and run our factories.  And we will transform our schools and colleges and universities to meet the demands of a new age.

Trump:

For many decades we've enriched foreign industry at the expense of American industry, subsidized the armies of other countries while allowing for the very sad depletion of our military.

One by one, the factories shuttered and left our shores with not even a thought about the millions and millions of American workers that were left behind.

Obama had a plan for growth. Trump just blames the rest of the world...

On global warming

Obama:

With old friends and former foes, we'll work tirelessly to lessen the nuclear threat, and roll back the specter of a warming planet.

Trump:

On the Middle East:

Obama:

To the Muslim world, we seek a new way forward, based on mutual interest and mutual respect. To those leaders around the globe who seek to sow conflict, or blame their society's ills on the West, know that your people will judge you on what you can build, not what you destroy. 

Trump:

We will re-enforce old alliances and form new ones and unite the civilized world against radical Islamic terrorism, which we will eradicate completely from the face of the earth.

On “greatness”

Obama:

In reaffirming the greatness of our nation we understand that greatness is never a given. It must be earned.

Trump:

America will start winning again, winning like never before.

 

On trade

Obama:

This is the journey we continue today.  We remain the most prosperous, powerful nation on Earth.  Our workers are no less productive than when this crisis began.  Our minds are no less inventive, our goods and services no less needed than they were last week, or last month, or last year.  Our capacity remains undiminished.  

Trump:

We must protect our borders from the ravages of other countries making our product, stealing our companies and destroying our jobs.

Protection will lead to great prosperity and strength. I will fight for you with every breath in my body, and I will never ever let you down.
