A Answer To Gudgin, Coutts & Gibson

The authors convey a post on the Prime website inward which they, amid other things, response to 2 weblog posts of mine where I cry their run on Brexit. In the get post they cry [1], I utilisation a graph from their newspaper to illustrate how of import the Single Market was for United Kingdom of Great Britain in addition to Northern Ireland of Britain in addition to Northern Republic of Ireland exports. Here is the graph.

I in addition to then wrote

“But didn’t the CBR written report state that the benefits of the Single Market had been exaggerated past times the Treasury? Yes it did. Here is some of its reasoning. That increment inward United Kingdom of Great Britain in addition to Northern Ireland of Britain in addition to Northern Republic of Ireland export portion afterwards the Single Market is non as impressive as it looks, because in that location is an underlying 6% positive tendency inward the share, which yous tin break before nosotros joined the EU. That looks pretty on a picture, until yous realise it is nonsense. H5N1 6% tendency ascent inward an export portion volition imply that at some request non likewise far away United Kingdom of Great Britain in addition to Northern Ireland of Britain in addition to Northern Republic of Ireland exports to the European Union volition last as high as total European Union GDP. United Kingdom of Great Britain in addition to Northern Ireland of Britain in addition to Northern Republic of Ireland exporters are only non that much improve than exporters inward other countries. There is no underlying tendency ascent inward the UK’s export share.”

By export share, it is obvious that I’m talking nearly portion inward finish GDP, as inward the chart. In my paragraph in that location is an error. I used a 6% figure rather than the right 3.5% figure for their tendency inward export penetration relative to the non-EU penetration. It was a especially stupid error, because only below Chart seven is Chart 8, which contains the right figure.

But, as the authors must know, this fault is non of import to my argument. Replace half-dozen past times 3.5 inward the relevant paragraph in addition to it withal makes perfect sense. What I was criticising was the notion that in that location was whatever substantial underlying tendency inward export penetration, in addition to that the deportment on of European Union membership should last judged relative to that trend. You tin run across from this nautical chart how ludicrous a 3.5% tendency is: it implies that without European Union membership the United Kingdom of Great Britain in addition to Northern Ireland of Britain in addition to Northern Republic of Ireland exports portion would last instantly higher upward 10% in addition to rising fast. This tendency seems to last an of import business office of their sentence that United Kingdom of Great Britain in addition to Northern Ireland of Britain in addition to Northern Republic of Ireland export penetration relative to the European Union would autumn past times substantially less than the Treasury assume inward their analysis. The tendency makes no sense, unless the aim is to brand the deportment on of European Union membership await small.

So what is the authors’ response to my basic criticism inward their Prime piece? There is none.

As far a the half-dozen rather than 3.5 is concerned, it is also odd is that this is the get fourth dimension they convey mentioned the fault to me. The post service was from mid-January, in addition to I would convey happily changed half-dozen to 3.5 if they had pointed it out to me earlier.

The minute post was a give-and-take of the notion of ‘fake economics’. I said simulated economic science could last described as “economic analysis or enquiry that is patently flawed but whose role is to back upward a detail policy.” or “We tin as beak nearly evidence based policy in addition to its simulated version, policy based evidence.” Here is what I wrote inward total nearly their study inward that post.

“The CBR analysis is less patently fake. However Ben Chu has gathered the views of some academics who are experts inward merchandise theory, including Richard Baldwin (who has only written a definitive in addition to widely praised book on the ‘new globalisation’) in addition to Alan Winters, both hugely respected amongst immense experience, who pour some real mutual frigidity H2O over the study.”

How do the authors response to this minute post service inward the Prime piece. They write

“It is odd for Wren-Lewis to rely uncritically on mainstream economists, but he was willing to do thus inward this case. With many of Wren-Lewis’ articles beingness used past times i of us inward economic science instruction to encourage students to query in addition to to exam what is considered ‘mainstream’ it seems to a greater extent than than a trivial surprising to last discredited for daring to do so.”

This is incorrect inward many ways. First, I was non relying on others, as I had serious misgivings nearly their utilisation of trends that I outline above. Second, I made no cry of ‘mainstream’ in addition to heterodox anywhere, thus whatever proposition that this was behind what I wrote is their invention. Finally, in that location is no work amongst anyone challenging anyone else.

Let me reproduce i of the quotes from Ben’s piece

“The HMT [Treasury] utilisation of gravity model was perfectly inward draw amongst best practice. It was classic evidence-based policy analysis”, said Richard Baldwin, Professor of International Economics at The Graduate Institute of Geneva. Professor Baldwin went on to bill Mr Gudgin himself of engaging inward “policy-based evidence making” in addition to “using evidence the agency a boozer uses a light post service – for support, non illumination”.

So Richard Baldwin was accusing the authors of just the simulated economic science that I talked about. Given my suspicions nearly their handling of trends discussed above, I felt justified inward writing nearly their slice inward this context.

I could convey ignored Richard Baldwin’s criticism in addition to my ain suspicions, in addition to non included them inward this post. But hither is some other quote from Ben’s piece:

“Dr Graham Gudgin of the CBR criticised the Treasury’s analysis, which predicted a major hitting to the United Kingdom of Great Britain in addition to Northern Ireland of Britain in addition to Northern Republic of Ireland economic scheme past times 2030 if the United Kingdom of Great Britain in addition to Northern Ireland of Britain in addition to Northern Republic of Ireland experienced a “hard Brexit”, inward unusually strident price describing it as “very flawed in addition to real partisan”. Dr Gudgin said he “suspected” Treasury civil servants had been leaned on past times ministers to ambit the results David Cameron in addition to George Osborne wanted.”

Recall that the Centre of Economic Performance argued, based on their ain extensive analysis, that the Treasury had underestimated the costs of Brexit, thus presumably the accusation of ‘very flawed in addition to real partisan’ applies to their analysis too. If i of the authors was happy to struggle that the analysis of others had been designed to ambit certainly results, I felt it alone fair to enquire the same query of the authors.
