evidence: New economic opportunity has also forged ties across the border. An unexpected result of the Good Friday Agreement has been the emergence of the "all-island economy", made up of businesses and industries that function as cross-border entities between Northern Ireland and the Republic of Ireland. [...] At the border itself, "cross-border trade has risen in large amounts in recent years, especially in goods", says Dr Eoin Magennis, senior economist at Ulster University. At least 30,000 people are thought to cross between the Republic of Ireland and Northern Ireland on a daily basis, including many for work. [...] Brexit has changed the dynamic somewhat. The end of The Troubles may have laid the foundation for economic cooperation, but it was logistically possible due to the creation of the EU Single Market in 1993, which allowed the free movement of goods, capital, services and labour across the Republic of Ireland-Northern Ireland border.
