In Ireland there are two separate economic entities. Their separation means they run up against the fundamental laws of economics, as first identified by Adam Smith[i].
In the first instance it is the size of the home market which determines the scope of the division of labour. But in Ireland both economies, by their separation, have a truncated home market. This was not always the case. As part of the British Empire the North East portion of the island was highly integrated into what was then the largest ‘home’ market in human history. At the same time most of the rest of the island was primarily a breeding ground for cattle, to help feed the large metropolitan imperial centres.
Post-Partition the situation has dramatically changed. The Empire is gone while the southern economy has both developed a home market of a certain size while integrating itself to one of the world’s largest markets in the EU. This is the key fundamental fact which explains the dramatic changes in average living standards in the two parts of the Ireland since Partition.
This is illustrated in Fig.1 below, which shows per capita GDP using common international Dollars (adjusted for Purchasing Power Parities, first Angus Maddison and then OECD). It amounts to a startling transformation of relative prosperity within Ireland.
To specify the data, Maddison shows that per capita GDP in Ireland in 1921 was $2,533 and that in Britain it was $4,439 (and from a variety of sources that average incomes in the north-east counties of Ireland was at least on a par with Britain). From OECD data per capita GDP in RoI was $37,581 in 2013 and in the UK it was 34,755 (and the ONS data shows NI per capita output was 82% of the UK level).
