Llull, Joan

My research focuses on labor economics, structural microeconometrics, and dynamic discrete choice models. I analyze the impact of migration, labor market dynamics, and wage inequality using structural equilibrium models. A large part of my work examines how immigration affects labor market outcomes, including wages, human capital, immigrant wage assimilation, labor market competition, and productivity. I also study the role of technological change in shaping wage inequality and labor mobility. My research extends to the design of optimal immigration policies, analyzing selective visa allocations, taxation schemes for high-skilled migrants, and redistribution mechanisms to balance the economic gains from immigration. Another part of my research agenda studies labor markets and human capital accumulation more broadly. A last part of my research agenda explores household decision making including marriage and fertility decisions and household finances. My work employs advanced econometric techniques to estimate structural models, including some methodological developments.

I am a Research Professor at the Institute for Economic Analysis (IAE-CSIC), Associate Research Professor at the Barcelona School of Economics (BSE), and a External Fellow at CReAM (University College London) and IZA. I received my PhD from CEMFI in 2011. Before joining the IAE-CSIC in 2023, I held positions at Universitat Autònoma de Barcelona and MOVE.

My research lies at the intersection of labor economics and structural microeconometrics, focusing on migration, labor market dynamics, occupational mobility, inequality, and human capital. I primarily estimate dynamic discrete choice models of equilibrium, but I also apply reduced-form approaches. My work has been published in leading journals, including the Review of Economic Studies, Journal of Human Resources, and European Economic Review, and has received significant recognition, including a Starting Grant and a Consolidator Grant from the European Research Council (ERC).

I am the first Data Editor for Econometrica, Quantitative Economics, and Theoretical Economics and serve on the Editorial Board of the Review of Economic Studies. Previously, I was the first Data Editor of the Economic Journal and Econometrics Journal, a Guest Editor for Labour Economics, and Associate Editor of SERIEs.

Beyond research, I am committed to mentoring, having supervised a large number PhD and master’s theses with placements in leading academic institutions.
