Human capital accumulation in an open labour market: Ireland in the 1990s

Large-scale investment in education in Ireland began in 1967 and has led to a dramatic increase in the relative supply of skilled labour over the past four decades. Furthermore the supply of labour in Ireland is traditionally highly elastic through migration, which in the 1990s was predominantly high-skilled. This combination of rising education levels and an open labour market meant that employment and incomes rose rapidly in the 1990s, while Ireland still maintained a strong competitive position in terms of relative labour costs.In this paper we develop a new macro-economic framework to formally analyse these mechanisms. We estimate a small structural model of the Irish labour market, separately identifying high-skilled and low-skilled labour. We find that this model captures key characteristics of the Irish labour market in the 1990s.
