Kelvin MacKenzie isn't a good macroeconomist

Transfers from rich areas to poor ones are really very useful for not screwing up the economy.

Former Sun editor Kelvin MacKenzie wrote a silly column yesterday. In it, he argued that "the middle class of London and the South East" are underserved by politicians, and called for a new political party which "believes that the striving classes in the South are overtaxed and overburdened".

It was, clearly, bunk. Charlie Hallam took most of it apart yesterday, pointing out that high pay is not the same as a large contribution to society, and that much of the boost London and the South East gets is merely entrenched advantage:

A start-up will find loans easier to obtain with a London address. Contacts are easier to make. Lobbying is easier. And there's that whole prejudice thing you don't have to deal with if you're based in the south.

The Economist's Daniel Knowles also points out that:

Every example he offers of London and the south being attacked takes the form of taxes on the rich—stamp duty for example—which also apply in the north. Meanwhile, the subsidy he says that the north gets is in the form of public spending: welfare benefits or social housing for example, which also apply in the south.

That is, far from wanting to fight for the South, MacKenzie is arguing for the rich of Britain and against the poor, wherever they actually are.

But there's a far simpler reason why MacKenzie is talking crap. The Telegraph's Ed West touched upon it in an otherwise faintly patronising post, writing:

Different parts of the economy require different economic policies, which is why the convergence of interest rates made the euro such a fundamentally bad idea for those countries on the fringe, such as Greece and Spain, since monetary policy would be set by people in Frankfurt and Brussels and therefore would be suited towards Frankfurt and Brussels. That’s a model that will work fine so long as the Greeks are prepared to live in perpetual poverty in the name of European solidarity, and that Germans are happy to pay the Greeks’ welfare bills.

The north and south of Britain are, by virtue of sharing the same currency, yoked to the same monetary policy. Short of some extraordinarily unorthodox economics – banknotes which catch fire south of Watford Gap? – that policy will be suboptimal for one or both areas of the country. Aggregate demand shocks rarely affect the nation uniformly, and so the Bank of England has to decide whether (say) inflation in the south is worth preventing a recession in the north.

But one way of lessening that impact is with common fiscal policy. That way, shocks in part of the country can be dealt with more quickly by transferring revenue from the healthy part to the struggling part. Which is, of course, exactly what MacKenzie was complaining about.

(It is worth noting that this analysis is roughly that which was relied on by every anti-Euro economist ever, who all feel very smug these days as Greece needs continual fiscal transfers just to stay in the economic bloc.)

The alternative – giving the north its own currency and monetary policy – may, I suppose, be what MacKenzie was angling for all along. It would certainly get those pesky Scousers out of his hair.

As a Conservative MP, I want Parliament to get a proper debate on Brexit

The government should consider a Green Paper before Article 50. 

I am very pleased that the government has listened to the weight of opinion across the House of Commons – and the country – by agreeing to put its plan for Brexit before Parliament and the country for scrutiny before Article 50 is triggered. Such responsiveness will stand the government in good stead. A confrontation with Parliament, especially given the paeans to parliamentary sovereignty we heard from Leave campaigners during the referendum, would have done neither the Brexit process nor British democracy any good.

I support the government’s amendment to Labour’s motion, which commits the House to respecting the will of the British people expressed in the referendum campaign. I accept that result, and now I and other Conservatives who campaigned to Remain are focused on getting the best deal for Britain; a deal which respects the result of the referendum, while keeping Britain close to Europe and within the single market.

The government needs to bring a substantive plan before Parliament, which allows for a proper public and parliamentary debate. For this to happen, the plan provided must be detailed enough for MPs to have a view on its contents, and it must arrive in the House far enough in advance of Article 50 for us to have a proper debate. As five pro-European groups said yesterday, a Green Paper two months before Article 50 is invoked would be a sensible way of doing it. Or, in the words of David Davis just a few days before he was appointed to the Cabinet, a “pre-negotiation white paper” could be used to similar effect.

Clearly there are divisions, both between parties and between Leavers and Remainers, on what the Brexit deal should look like. But I, like other members of the Open Britain campaign and other pro-European Conservatives, have a number of priorities which I believe the government must prioritise in its negotiations.

On the economy, it is vital that the government strives to keep our country fully participating in the single market. Millions of jobs depend on the unfettered trade, free of both tariff and non-tariff barriers, we enjoy with the world’s biggest market. This is absolutely compatible with the result, as senior Leave campaigners such as Daniel Hannan assured voters before the referendum that Brexit would not threaten Britain’s place in the single market. The government must also undertake serious analysis on the consequences of leaving the customs union, and the worrying possibility that the UK could fall out of our participation in the EU’s Free Trade Agreements (FTAs) with non-EU countries like South Korea.

If agreeing a new trading relationship with Europe in just two years appears unachievable, the government must look closely into the possibility of agreeing a transitional arrangement first. Michel Barnier, the European Commission’s chief negotiator, has said this would be possible and the Prime Minister was positive about this idea at the recent CBI Conference. A suitable transitional arrangement would prevent the biggest threat to British business – that of a "cliff edge" that would slap costly tariffs and customs checks on British exports the day after we leave.

Our future close relationship with the EU of course goes beyond economics. We need unprecedentedly close co-operation between the UK and the EU on security and intelligence sharing; openness to talented people from Europe and the world; and continued cooperation on issues like the environment. This must all go hand-in-hand with delivering reforms to immigration that will make the system fairer, many of which can be seen in European countries as diverse as the Netherlands and Switzerland.

This is what I and others will be arguing for in the House of Commons, from now until the day Britain leaves the European Union. A Brexit deal that delivers the result of the referendum while keeping our country prosperous, secure, open and tolerant. I congratulate the government on their decision to involve the House in their plan for Brexit - and look forward to seeing the details.
