AbstractThis paper provides an empirical analysis of the relationship between preferential trade agreements (PTAs) and bilateral migration flows. Building on the empirical literature on the determinants of migration flows, I estimate a modified gravity model to assess the role of PTAs and their content on bilateral migration flows. Using a sample of 29 OECD destination countries over the period 1998–2008, I show a strong positive effect of PTAs on bilateral migration flows. I find that the content of PTAs also matters: when visa‐and‐asylum and labour market related provisions are included in PTAs, this further stimulates bilateral migration flows. Different estimation strategies, including instrumental variables, are employed to address the potential endogeneity bias problems related to PTAs and their content.

This paper investigates empirically the role of Preferential Trade Agreements (PTAs) as determinants of migration inflows for 29 OECD countries in the period 1998-2008. By increasing information about signatory countries, PTAs are expected to drive migration flows towards member countries. Building on the empirical literature on the determinants of migration, I estimate a modified gravity model on migration flows providing evidence of a strong positive effect of PTAs on bilateral migration flows. I also consider the content of PTAs as a further determinant of migration, finding that visa-and-asylum and labour market related provisions, when included in PTAs, stimulate bilateral migration flows. Finally, by comparing the average effects of PTAs on migration flows and on trade, I show that PTAs stimulate bilateral migration flows more than trade in final goods. PTAs might be used by government to increase inflows of immigrant workers in the case of labour shortages or population ageing.
