The Economist endorses NGDP targeting. Well, sort of…

The Economist endorses a bit of NGDP targeting, for a bit, in a bit.

The Economist has an editorial in this week's magazine calling for a form of nominal GDP targeting. The editorial reads:

At the moment the Bank of England’s mission, set by the chancellor of the exchequer, is to focus on an inflation target of 2%. That makes sense in normal circumstances. But with short-term interest rates at almost zero, the economy growing at barely 2% in nominal terms (and not at all if you factor in inflation) and many years of austerity ahead, it is worth temporarily reinterpreting that policy and focusing on nominal GDP. Our suggestion is that the bank, backed by the chancellor, George Osborne, should make clear that it will not tighten policy until nominal GDP, currently £1.5 trillion, gets to a level that is at least 10% higher than today.

The magazine is clearly happy to call what it's suggesting a nominal GDP target, but that's not really the case. Instead, the suggestion is more akin to the US's recent adoption of the so-called Evans Rule, which stated that:

The interest rate is guaranteed to stay at its historic low of 0-0.25 per cent until unemployment is below 6.5 per cent or inflation is above 2.5 per cent.

The American case is different for two key reasons: the first is that the Federal Reserve's Open Market Committee, which sets monetary policy, has a dual mandate, requiring it to keep both inflation and unemployment low. The FOMC had been doing a good job keeping the former down, but not such a good job with the latter. The second is that growth in the State is doing OK; again, the real concern was that, in focusing too heavily on inflation, the Fed might choke off that recovery.

But both the Evans rule and the Economist's rule — let's call it the Micklethwait rule — are more about binding the monetary policy committees' future actions. They are a way of communicating to the markets that the rates will not be raised until good things happen, and that the traditional role of the central banks (to keep inflation under control) will be put to one side in the meantime.

The fact that the Micklethwait rule is described in terms of "nominal GDP" makes it sound like a nominal GDP target, but it's not. The latter, a dreadfully trendy prospect in economics circles at the moment, involves commanding the central bank to target a specific level of nominal GDP (that is, GDP unadjusted for inflation). Its benefits are that it explicitly allows for a burst of inflation to get us out of a depression, and commands central bankers to not just restore growth after a slump, but to increase nominal GDP to the level it would be if that slump hadn't actually happened.

The Micklethwait rule would allow for the first — but only as a one time thing, since it would need to be re-enacted in a future depression — but explicitly prevents the second. It only gets half the benefits of true nominal GDP targeting, but all of the downsides, particularly the big one: before we can target NGDP, we need to be able to measure it. Given the ONS's revisions to real GDP, made over the span of three months, are still subject to enormous revisions, the thought of it having to make them three times as fast, for a new measure of the country's production, and get them right first time seems faintly ludicrous.

That's not to say that the Micklethwait rule might not be better than what we have at the moment. Just that if we're going to go to all that trouble, we may as well leap into the great unknown with both feet, rather than just stumbling off the cliff out of desperation.

The Tories play Game of Thrones while the White Walkers from Brussels advance

The whole premise of the show is a pretty good metaphor for the current state of British politics.

If you’re a fan of asking “who’s that, then?” and “is that the one who killed the other one’s brother?”, I bring great news. Game of Thrones is back for a seventh series. Its vast assortment of characters was hard enough to keep track of before half of them got makeovers. But now the new Queen Cersei has reacted to the arrival of the long winter by investing heavily in the kind of leather ball gowns sold by goth shops in Camden, and Euron Greyjoy, once a fairly bland sailor, has come back as a Halloween costume version of Pacey from Dawson’s Creek, all eyeliner and epaulettes.

The show’s reliance on British character actors is the only thing keeping me vaguely on top of the cast list: what’s Diana Rigg up to these days in Highgarden? And what about that guy who was in Downton Abbey that time, who now has the scaly arms? (Luckily, the next thing I watched after the Game of Thrones series premiere was the first two episodes of the revived Twin Peaks, which put my confusion into perspective. There, Agent Cooper spent most of his time talking to a pulsating bladder attached to one of those fake trees you get from Ikea when your landlord won’t let you have real plants.)

The day-to-day business of Game of Thrones has always been power – answering the question of who will sit on the Iron Throne, forged by Aegon the Conqueror from the swords of his defeated enemies. But its backdrop is a far bigger threat: the arrival of a winter that will last many years, and the invasion of an army of the undead.

That might seem like an unkind way to think about Michel Barnier and his fellow Brexit negotiators – inexorably marching towards us, briefing papers in hand, while Liam Fox frantically rings a bell at the entrance to the Channel Tunnel – but nonetheless, the whole premise of Game of Thrones is a pretty good metaphor for the current state of British politics.

The current internal Conservative struggle for power might be vicious but it is at least familiar to its contestants; they know which weapons to deploy, which alliances are vital, who owes them a favour. Meanwhile, the true challenge facing every one of them is too frightening to contemplate.

In 2013, this magazine celebrated the early success of the show with a cover depicting one of our terrifying painted mash-ups: “The Tory Game of Thrones.” Our casting has been strangely vindicated. George Osborne was our Jaime Lannister – once the kind of uncomplicated bastard who would push a child out of a window but now largely the purveyor of waspish remarks about other, worse characters. Our Cersei was Theresa May, who spent the early seasons of The Cameron Era in a highly visible but underwritten role. Now, she has just seized power, only to discover herself beset by enemies on all sides. (Plus, Jeremy Corbyn as the High Sparrow would quite like her to walk penitently through the streets while onlookers cry “shame!”)

Michael Gove was our Tyrion Lannister, the kind of man who would shoot his own father while the guy was on the loo (or run a rival’s leadership campaign only to detonate it at the last minute). Jeremy Hunt was Jon Snow, slain by the brotherhood of the Night Shift at A&E, only in this case still waiting for resurrection.

The comparison falls down a bit at Boris Johnson as Daenerys Targaryen, as the former London mayor has not, to my knowledge, ever married a horse lord or hired an army of eunuchs, but it feels like the kind of thing he might do.

We didn’t have David Davis on there – hated by the old king, David Camareon, he was at the time banished to the back benches. Let’s retrospectively appoint him Euron Greyjoy, making a suspiciously seductive offer to Queen Cersei. (Philip Hammond is Gendry, in that most of the country can’t remember who he is but feel he might turn out to be important later.)

That lengthy list shows how Conservative infighting suffers from the same problem that the Game of Thrones screenwriters wrestle with: there are so many characters, and moving the pieces round the board takes up so much time and energy, that we’re in danger of forgetting why it matters who wins. In the books, there is more space to expound on the politics. George R R Martin once said that he came away from The Lord of The Rings asking: “What was Aragorn’s tax policy?” (The author added: “And what about all these orcs? By the end of the war, Sauron is gone but all of the orcs aren’t gone – they’re in the mountains. Did Aragorn pursue a policy of systematic genocide and kill them? Even the little baby orcs, in their little orc cradles?”)

Martin’s fantasy vision also feels relevant to the Tories because its power struggles aren’t about an “endless series of dark lords and their evil minions who are all very ugly and wear black clothes”. Instead, everyone is flawed. In Westeros, as in the Conservative Party, it can be difficult to decide who you want to triumph. Sure, Daenerys might seem enlightened, but she watched her brother have molten gold poured down his throat; plucky Arya Stark might tip over from adorable assassin into full-blown psychopath. Similarly, it’s hard to get worked up about the accusation that Philip Hammond said that driving a train was so easy “even a woman” could do it, when David Davis marked his last leadership campaign by posing alongside women in tight T-shirts reading “It’s DD for me”.

The only big difference from the show is that in real life I have sympathy for Barnier and the White Walkers of Brussels. Still, maybe it will turn out that the undead of Game of Thrones are tired of the Seven Kingdoms throwing their weight around and are only marching south to demand money before negotiating a trade deal? That’s the kind of plot twist we’re all waiting for.
