The Undercover Economist Strikes Back: by far the worst thing about it is the title

Tim Harford's book reviewed.

Tim Harford is perhaps the best popular economics writer in the world. This is both less and more of an achievement than it sounds: less because he has little in the way of competition for the title and more because the reason there is so little competition is that doing popular economics well is very hard.
 
There are other economists who write for a wide audience. By far the most prominent is Paul Krugman, the Nobel laureate and prolific blogger/columnist for the New York Times. Yet while Krugman might have intended to explain economics to the masses when he started his NYTgig, his column rapidly became highly political and he became a polarising figure. In any case, he doesn’t seem to care much about explaining economics in his columns except in so far as doing so helps him to make a broadly political point (usually that the Republicans are wrong and the Democrats should spend more).
 
There are also some commentators on economics, foremost among them Martin Wolf of the Financial Times, who play an invaluable role in helping to frame and explain – and sometimes adjudicate – the important debates taking place at the intersection of economics and policy. Wolf is erudite, well sourced and highly influential but to call him “popular” would be pushing things too far. His columns are dense, difficult things, written in large part with an audience of senior policymakers in mind. If you’re already an economics sophisticate, then you can learn a lot from them. If you are not, they will verge on the incomprehensible.
 
Harford takes a very different tack. He is in many ways most similar to the “two Steves” of Freakonomics – the economist Steven D Levitt and the journalist Stephen J Dubner. The Freakonomics project seeks to make economics accessible, looking at the way that it manifests itself in everyday life and calling out interesting findings from microeconomic literature. The impetus is praiseworthy but the results can be exaggerated, contentious, oversimplified, or just plain sensationalist.
 
Harford, by contrast, keeps his feet on the ground. He has a breezy writing style and an infectious sense of humour – but he doesn’t let himself go further than a sober, conservative economist would be comfortable going. He’s trustworthy in a way that most other commentators on economics aren’t. He is not particularly interested in political arguments or in imposing his views on others – instead, he just wants to explain, as simply and clearly as possible, the way in which the economics profession as a whole usually looks at the workings of the world.
 
Harford, like Levitt, is a microeconomist by training and by avocation; he is most comfortable when faced with questions such as: “Why does a return train ticket on British rail cost only £1 more than a single?” Hence his Undercover Economist franchise: the conceit is that he’s an economist spying on the world, explaining things – and answering readers’ questions – in a way that only an economist would.
 
With The Undercover Economist Strikes Back, however, Harford has taken a leap out of his microeconomic comfort zone. By far the worst thing about it is the title. There is none of the Undercover Economist about this book, unless you include the dialogue style of writing that Harford has perfected in his FT column. And he’s not striking back at anything at all: no entity was attacking him in the first place. Even the subtitle (How to Run – or Ruin – an Economy) is problematic. No one is going to come away from reading this book convinced that they know how to run an economy.
 
Instead, what Harford has achieved with his new book is nothing less than the holy grail of popular economics. While retaining the accessible style of popular microeconomics, he has managed to explain, with clarity and good humour, the knottiest and most important problems facing the world’s biggest economies today.
 
He is no fatalist when it comes to macro: it is important; there are things we know are true; there are things we know are false; what we do can and does make a tangible difference to how wealthy and happy we become. He explains these things in an unprecedentedly accessible way, making liberal use of quotations from The Hitchhiker’s Guide to the Galaxy and Dr Strangelove.
 
By the end of it all, you will understand everything from liquidity traps to the Lucas critique – and your eyes won’t glaze over when reading about such things. Harford has written the “macroeconomics for beginners” book we have all been waiting for; I just wish that it had been published as such, and not as something targeting only Harford’s existing audience.

Scotland's vast deficit remains an obstacle to independence

Though the country's financial position has improved, independence would still risk severe austerity. 

For the SNP, the annual Scottish public spending figures bring good and bad news. The good news, such as it is, is that Scotland's deficit fell by £1.3bn in 2016/17. The bad news is that it remains £13.3bn or 8.3 per cent of GDP – three times the UK figure of 2.4 per cent (£46.2bn) and vastly higher than the white paper's worst case scenario of £5.5bn. 

These figures, it's important to note, include Scotland's geographic share of North Sea oil and gas revenue. The "oil bonus" that the SNP once boasted of has withered since the collapse in commodity prices. Though revenue rose from £56m the previous year to £208m, this remains a fraction of the £8bn recorded in 2011/12. Total public sector revenue was £312 per person below the UK average, while expenditure was £1,437 higher. Though the SNP is playing down the figures as "a snapshot", the white paper unambiguously stated: "GERS [Government Expenditure and Revenue Scotland] is the authoritative publication on Scotland’s public finances". 

As before, Nicola Sturgeon has warned of the threat posed by Brexit to the Scottish economy. But the country's black hole means the risks of independence remain immense. As a new state, Scotland would be forced to pay a premium on its debt, resulting in an even greater fiscal gap. Were it to use the pound without permission, with no independent central bank and no lender of last resort, borrowing costs would rise still further. To offset a Greek-style crisis, Scotland would be forced to impose dramatic austerity. 

Sturgeon is undoubtedly right to warn of the risks of Brexit (particularly of the "hard" variety). But for a large number of Scots, this is merely cause to avoid the added turmoil of independence. Though eventual EU membership would benefit Scotland, its UK trade is worth four times as much as that with Europe. 

Of course, for a true nationalist, economics is irrelevant. Independence is a good in itself and sovereignty always trumps prosperity (a point on which Scottish nationalists align with English Brexiteers). But if Scotland is to ever depart the UK, the SNP will need to win over pragmatists, too. In that quest, Scotland's deficit remains a vast obstacle.
