It’s that time of year again when shamrockery, Guinness and “Kiss me I’m Irish” hats come to the fore in presenting a particular image of “Irishness” to the world.

When the sons and daughters of the diaspora will celebrate “Patty’s Day” by eating corned beef and cabbage, downing green beer and jumping around to the House of Pain.

It’s all harmless fun, of course. Though some may not approve of the version of Ireland it portrays, our politicians and tourism agencies will wring the very last drop of green from St Patrick’s Day for maximum fiscal effect.

There is another Ireland that has been making its way in the world for centuries, however, making a positive impact around the globe and what better time to celebrate some of those real Irish achievements.

In Essai, as it is commonly abbreviated, Cantillon outlines a systematic modern economic theory covering a range of now core economic ideas including cause and effect, monetary theory, entrepreneur theory and spatial economics. Cantillon’s Essai is now regarded as having huge significance in the development of modern economic theory and influenced many of those who followed including Adam Smith, who cited it in his Wealth of Nations.
