Brexit: United Ireland only way to avoid 'negative economic impact'

A German economist has suggested the only way for NI to avoid negative economic impacts of Brexit is to unite with the Republic of Ireland.

Kurt Hubner's conclusion is in a report examining the impact of different Brexit scenarios on Ireland.

It suggests unification would mean that by 2025 Northern Ireland's economic output would be almost £16bn higher than it otherwise would have been.

Economists do not agree about the potential benefits of unification.

The major issue concerns the subvention that Northern Ireland receives from Westminster - the shortfall between what Northern Ireland spends on services and raises in taxes.

Dr Hubner's economic model effectively suggests that unification would lead to major productivity and output gains which would more than cover the subvention.

It continues to suggest a positive, albeit smaller, impact of about 10,000 euros per head by 2025 in event of reunification.

By contrast, Dr Hubner suggests a hard Brexit, on World Trade Organisation terms, would mean output per head would be by about 10,000 euros (£8,732) less by 2025 compared to what it would be in a no-Brexit scenario.

Even with a scenario in which Northern Ireland remained in the single market both parts of Ireland would suffer losses in comparison to a no-Brexit scenario.

He states: "Compared to a hard-Brexit, unification is by far the better option.

"As a matter of fact, it is the only option with positive net effects."

Dr Hubner's model suggests that the the adoption of the Irish tax system, greater openness to foreign direct investment and reduced trade barriers would see Northern Ireland enjoy a period of "economic catch up."

Recent research by Dublin-based economists John FitzGerald and Edgar Morgenroth suggested unification could reduce incomes and living standards for people in the Republic of Ireland by as much as 15%.

In a tweet commenting on the report, Irish Justice Minister Charlie Flanagan said that "conflating Brexit with Irish unity is unhelpful and misguided".
