Because of its smaller
tax base, some experts from the
Republic of Ireland say that the country could not make up the subsidy in the event of
reunification of Ireland. A 2019 report by
John Fitzgerald and Edgar Morgenroth, academics of the
Trinity College Dublin, found that withdrawal of the subsidy would cause "calamitous unemployment and emigration". According to their analysis, if the Republic covered the subsidy it would lead to a five to 10 per cent decrease in the standard of living. They recommended reforms in Northern Ireland's economy to reduce the need for subsidy and preserve the possibility of reunification. In 2021,
Dublin City University international relations scholar John Doyle cited argued that the figure of £10 billion fiscal deficit "is a UK accounting exercise" because it includes UK government costs that Northern Ireland would not pay if it left the UK and does not account for predicted economic growth. Doyle "concludes that those elements of the current subvention that are likely to transfer to a united Ireland would represent a deficit of approximately €2.8b". In a reply to the paper, economist
Alan Barrett agreed that the real deficit upon reunification would be lower than the official figure for the subvention (9.4 billion) but Barrett argued that it was likely higher than the figure Doyle gave, because Barrett considers it unlikely that the UK would agree to continue paying the full cost of Northern Ireland pensions (3.4 billion) and debt interest (1.6 billion) after reunification. ==References==
