Free trade and a hard Brexit are all but synonymous. There’s an obsessive quality about free traders, men on a mission, who feel their time has come: seize the moment, lest it slip away.

Daniel Hannan and Boris Johnson recently helped launch the Institute of Free Trade, arguably duplicating the work of the long-established Institute of Economic Affairs. I’ve always had a sense of vast lacunae between argument and reality among free traders, and I turned to an article on the IEA website, by its chief economist, Julian Jessop, to check out whether this judgement was justified. For the full article see:  https://iea.org.uk/whos-afraid-of-free-trade/

Jessop expresses puzzlement as to why ‘the economics commentariat’ (i.e. most economists) had given a ‘sceptical, with some downright hostile’ response to two papers advocating a policy a free trade once the UK leaves the EU, by Professors Kevin Dowd and Patrick Minford.

It may be unfair to quote passages and not reproduce the whole article, but to my mind they do speak for themselves.

‘… it has been suggested that Prof Minford’s analysis shouldn’t be taken too seriously because his forecasts of the economic and market impacts of the vote itself were inaccurate. As it happens I don’t know what Prof Minford was forecasting in 2016. But nor, frankly, do I care….’

‘Professor Minford’s current and past work in this area has been challenged for using what some regard as a simplistic and out-dated model of world trade. But the ‘gravity models’ favoured by many of his critics also have their flaws. Even if Professor Minford’s numbers are only as good as his models (which is always the case) …’

The phrase, ‘the underlying principles are as sound as any’, is key: there is a millenarianist belief in free trade as a universal panacea, the UK’s adoption of which will open the eyes of the rest of the world, as Britain did once before, in the early 19^th century. ‘Gravity models’ refers to the long-established and incontrovertible pattern of a much heavier weighting toward trade with one’s neighbours, than with more distant countries.

Nonetheless, whatever the correct interpretation here, these legal points do not weaken the more important economic argument that the UK would be better off lowering its own trade barriers regardless of how the rest of the EU responds.

Free trade it seems works because it works, regardless of circumstance. In what sense better off – who would be better off?

‘… of course, there would be some losers from free trade among consumers as well as producers …

‘….there would be some losers..’ The reality is that the disruption would be extraordinary.

Others have suggested that trade can never be fully ‘free’, because of non-tariff barriers. But this is tedious semantics. Even if unilateral free trade only results in freer trade, relative to the status quo, that would be an improvement.

‘…tedious semantics’? There’s an impatience here, a touch of the Gadarene swine.

What then about things that we do produce ourselves but where other countries have a genuine comparative advantage? Why should we subsidise domestic producers if consumers can buy better or cheaper products elsewhere?

A few suggestions as to why… Easily disrupted supply chains, sourcing expensively at long distance, security implications, quite apart from the disruption to urban and rural landscapes as industries close and new ones – we would hope – spring up elsewhere. But in the chaos, and the economic disruption, what certainty is there that new industries, competitive on the world stage, would rise up?
