In this article, we will be taking a look at the 15 largest companies headquartered in Ireland.
The third-largest island in Europe, Ireland boasts a highly developed knowledge which is focused on financial services, life sciences, high-tech and agribusiness. Considered to be an open economy, Ireland ranks top in the world for high-value foreign direct investment while in terms of GDP per capita, it ranks 4th in lists compiled by the International Monetary Fund as well as the the World Bank. All of this is even more impressive considering the fact that after consistent growth for 23 years, Ireland was badly affected by the global 2008 financial crisis after the collapse of the Irish property bubble, which resulted in the country entering a recession.

Ireland’s economy finally rebounded in 2011, growing by 2.2%, followed by 0.2% in 2012, before plunging into another crisis driven by the European sovereign-debt crisis before rebounding again. There have been accusations that Ireland’s economic growth is distorted due to Ireland having favorable corporate tax regimes which has led to many major foreign companies merging with companies in Ireland and moving their headquarters to the company to take advantage of the aforesaid corporate tax regime. Mainly companies in the United States have decided to move their headquarters to Ireland starting with Accenture in 2009. To a lesser extent, the United Kingdom also has had companies moving their headquarters to Ireland. This has also been dubbed as “leprechaun economics” by economists while a few multinationals including the Central Bank of Ireland have proposed alternative methods of calculation. These moves, especially for companies in the United States have said to have reduced the effective tax rate on corporations from 30% to 20% while these corporations have highly artificially inflated the GDP of the country.
