Why the economics profession remains blind to the benefits of Brexit
The office for National Statistics last week estimated that the UK economy grew at an annual rate of 2.4 per cent in the final quarter of last year. This is slightly above the long-term average growth of the past three decades.
But a Financial Times survey this month showed that the majority of economists remain just as pessimistic about Brexit’s likely effect on Britain’s economic prospects as they were a year ago.
How can this be? Why is the economics profession so overwhelmingly opposed to Brexit?
The reasons rest on two important underpinnings of the discipline. First is a belief in the benefits to society of free trade. There is substantial empirical evidence which backs up economists’ views on this matter.
As the referendum showed, this is a contested issue. The Cambridge economist Bob Rowthorn has pointed out that “there has already been a sharp fall in the size of the Euro-area economy as a proportion of the world economy, and it is hard to see how this trend will not continue”. The deals we need are with fast-growing countries like India and China, and with enormous and innovative markets like the United States. Whether we can get a better deal in or out of the EU is a matter of judgement, not theory.
But the more important reason is that economic theory is in essence about equilibrium. It is about how best to allocate a fixed amount of resources in a static world. Economics has relatively little to say about dynamic processes, about change, about disruption, evolution, innovation, about behaviour out of equilibrium.
This emphasis on a static world leaves many economists unable to see the serious failings of the EU, both actual and potential. In the 1970s and into the 1980s, before the impact of the Thatcher reforms had been felt, it was indeed sensible to look to Europe for inspiration. The UK was plagued by high inflation and low growth.
But now we have had nearly two decades of the euro, one of the most efficient job destruction machines ever created. The combined impact of the euro and their own internal corruption has led output in Italy, Portugal, Spain and Greece to be much lower now than it was 10 years ago. This is a recession without parallel in economic history in its length and severity.
The ability to innovate is the key to long-term growth, as America has shown with Microsoft, Google, Facebook and others. Economic theory has very little to say about innovation. And this blinds the economics profession to the failings of the EU.
