The monograph examines the historical prerequisites for the emergence and evolution of the so-called "economic miracle", known as the phenomenon of the "Celtic Tiger" in Ireland. The author, in particular, examines the characteristic features of Ireland's economic growth, which made possible the transformation of this country into a "Celtic Tiger", showing the role of economic policy and international economic conditions. The focus is on identifying the underlying factors that have determined economic growth both at the macro level and in the manufacturing sector between 1950 and 2020. For this purpose, an endogenous growth model based on the mapping of the mechanism of technological progress has been used. The role of external factors is revealed by econometric analysis of the demand side of GDP, as well as the effect of globalization associated with foreign direct investment.
