2026

Paper forthcoming in AER

Our paper "Labor Market Competition and the Assimilation of Immigrants" was finally forthcoming in February 2026. Here's (my reaction to) the AEA announcement:

Article in Cent per Cent about the migrant regularization debate

In February 2026 the newspaper Cent per Cent published an article discussing the debate around the proposed extraordinary regularization of migrants in Spain. In the piece I comment on the potential economic effects of such a policy, noting that in the short run regularization often has positive effects because people who are already living in the country can work legally, pay taxes, and contribute to Social Security. At the same time, the longer-term impact depends on whether the policy generates expectations of future regularizations and therefore changes migration incentives. You can read the article here.



2025

CORDIS-EU summarizes the results of the DYMOLAMO ERC project

In November 2025 the European Commission’s CORDIS platform summarized the main results of my ERC Starting Grant project DYMOLAMO (Dynamic Modeling of Labor Market Mobility and Human Capital Accumulation). The project developed dynamic models to study labor mobility, human capital accumulation, and immigration, providing new insights into issues such as immigrant assimilation, labor market institutions, and the effects of immigration policies on wages and productivity. You can read a summary of the project’s results on the CORDIS website here, and a comment in the news section of the IAE-CSIC website here.

Commentary on the Calvó-Armengol Prize on "Cierre de Mercados"

In October 2025 I participated in the radio programme Cierre de Mercados (Radio Intereconomía) to discuss the contributions of Johannes Stroebel, who was awarded the 2025 Calvó-Armengol International Prize in Economics. As a member of the prize’s selection committee, I commented on how Stroebel’s research highlights the importance of social networks, beliefs, and interactions in shaping economic and financial outcomes, and how these insights help us better understand phenomena such as housing market dynamics and the diffusion of financial behaviour. You can read a comment in the news section of the IAE-CSIC website here, and listen to the interview below (my intervention begins around minute 42:46 of the podcast).

Roundtable on migration

Interview in ARA on Brussels' immigration forecasts

You can read the news article here, and a comment in the news section of the IAE-CSIC website here.

Interview on IB3 Radio about Trump’s trade war

In April 2025 I was interviewed by IB3 Radio about the potential global economic effects of the trade war initiated by Donald Trump.
