Martín Brun Moratorio

Martín Brun Moratorio is a Postdoctoral Research Fellow at the Finnish Centre of Excellence in Tax Systems Research (FIT) at Tampere University's Faculty of Management and Business. He earned his PhD from Universitat Autònoma de Barcelona (UAB) in 2024 and maintains affiliations with Economics of Inequality and Poverty Analysis (EQUALITAS) and the Network on Welfare and Policy in Latin America and the Caribbean (WAPLAC).

His research program centers on Behavioral and Experimental Economics, with particular emphasis on how cognitive abilities shape economic decision-making. Brun has conducted innovative lab-in-the-field experiments with school students to investigate the developmental trajectory of fairness preferences, finding that meritocratic views increase with age and cognitive ability. His methodological approach combines experimental economics with careful analysis of cognitive processes.

Brun's publication record reveals three interconnected research strands: (1) the relationship between cognitive ability and economic preferences (particularly regarding redistribution and health policy), (2) the development of fairness preferences during adolescence, and (3) reproducibility in economic research. His recent work demonstrates that high-cognition individuals show greater support for redistribution and circumstance-based vaccine distribution, suggesting a link between cognitive processing and prosocial preferences.

He actively participates in collaborative research examining:

• Cognitive development and fairness preferences
• Role models and STEM education engagement
• Taxation effects on tourism
• Study practices in higher education
• Reproducibility challenges in economics

Brun's methodological contributions extend to large-scale replication efforts, where he has examined researcher variation in experimental design and analysis. His work bridges theoretical insights with practical policy implications across multiple economic domains.
