Economic Guest Researchers

2026 - Brenda Adiwijaya

From January to the end of March, 2026, Brenda Adiwijaya is visiting the IAAEU. Brenda is a third-year doctoral student at the Department of Economics at the University of Insubria in Italy. In her dissertation, Brenda analyses the relationship between historical norms and modern-day decision on daycare use. During her stay at the IAAEU she will use German data to investigate the relationship between a women’s decision to join the labour force and childcare availability. We welcome Brenda Adiwijay to the IAAEU and hope that she will enjoy a productive and rewarding stay.

2025 - Martín Besfamille

From December 9 to 21, 2025, Professor Martín Besfamille visited the IAAEU. He is an Associate Professor at the Institute of Economics of the Pontifical Catholic University of Chile in Santiago and a Research Fellow at CESifo. His research focuses on fiscal federalism and decentralization, the circumvention of legal restrictions, and tax evasion.

During Martín Besfamille's stay at the IAAEU, he and Laszlo Goerke continued working on a joint project that they had started a few years earlier during a visit to CESifo in Munich. They continued the investigation during Martín Besfamille's last stay in Trier a year ago and on the occasion of two visits by Laszlo Goerke to Santiago de Chile. The joint project aims to analyze the impact of the interaction between tax and antitrust authorities in oligopolistic markets.

2024 - Martín Besfamille

Dr. Martín Besfamille visited the IAAEU from December 12 to 21, 2024. He is an Associate Professor at the Instituto de Economía in Pontificia Universidad Católica de Chile and a research fellow at CESifo.

During his stay at the IAAEU, Martín Besfamille and Laszlo Goerke worked on a joint project they commenced some years ago when visiting CESifo in Munich and continued during a visit by Laszlo Goerke in Santiago de Chile early in 2024. The starting point is the insight that many government agencies pursue particular objectives but ignore the impact on the market interventions by other agencies. The joint project aims to analyse the relationship between the behaviour of two such agencies in the context of an oligopolistic model à la Cournot.
