This PhD position will be within the Behavioural Economics research group at the Erasmus School of Economics. We are looking for a full time PhD student starting on September 1, 2025. The research topic falls within the intersection of behavioral economics and social psychology. Broadly, the topic will address “how can we elicit more honest behavior”. Relevant research areas are behavioral analysis, behavioral change, and decision-making in the context of ethics, dishonesty, and deception.

Job description
Aligned with the general vision of the Behavioural Economics research group, the prospective PhD student will advance our understanding of human behaviour and the factors that shape it. The particular aim of this PhD vacancy is to understand and improve ethical decision-making – to understand how individuals make ethical decisions in highly complex environments. The PhD student can investigate which factors drive their (dis)honest behavior and how we can help them to make more honest decisions. This topic will be investigated using quantitative research methods, such as online and lab experiments. More information on the members and research of the group is available here: https://www.eur.nl/en/ese/department-applied-economics/behavioural-economics/people

The successful candidate will be supervised by dr. Sophie van der Zee and at least one other member of this research group. The Behavioural Economics group is a part of the Department of Applied Economics of the Erasmus School of Economics (ESE). The group’s research is on the intersection of behavioral economics and social psychology. As such, most members are affiliated with the Tinbergen Institute and/or the Erasmus Research Institute in Management (ERIM). This interdisciplinary approach also shows in the publication record of the group, which encompasses top economics, finance, psychology, management, and political science journals such as Econometrica, The Review of Financial Studies, Management Science, Experimental Economics, Nature Communications, Psychological Science, the American Political Science Review, European Economic Review, Journal of Economic Psychology, and many more.

The successful candidate will be able to choose an affiliation with ERIM or Tinbergen Institute depending on personal preference and the specific research topic. The specific topic of the research project is open and will be determined in coordination between the candidate and supervisors within the broader topic described above.

As a final output, the candidate is expected to write at least 3 academic papers (cumulative PhD thesis) with the aim to be submitted to journals in economics journals during or after the PhD trajectory.

General Requirements:

• MPhil or Research Master’s degree in Economics, Econometrics, Mathematics or Physics is preferred
  
  • Candidates with an MSc or MA degree are required to successfully complete 1 year of courses at the graduate school they are part of (Research Qualifications at the Tinbergen Institute or courses at ERIM)
• Excellent study results for both the bachelor and master’s degree
• Interest in and strong motivation for scientific research explained in a statement of purpose.
• GRE test is required for all entering PhD students. Valid GRE (revised) General Test results are required from all PhD applicants (all 3 sections: Verbal Reasoning, Quantitative Reasoning and Analytical Writing). Successful applicants typically perform among the top-10% of test-takers on the quantitative part of the GRE; applicants with a Q score below 160 will not be considered.
• Excellent command of English (IELTS/TOEFL). Students whose native language is not English are therefore required to demonstrate English proficiency by:
  
  • holding a degree from a Dutch university or an institution at which English is the language of instruction, or
  • scoring at least 100 on the TOEFL iBT test or 7 on the IELTS test.
• Two (academic) reference letters, preferably from a thesis supervisor or research project supervisor.

The Behavioural Economics group is part of the Department of Applied Economics of the Erasmus School of Economics (ESE). The group’s vision is to help people understand their current decisions and help them change behaviour for the better. The research is guided by insights from behavioural economics, finance, and psychology. Behavioural economics provides us with the necessary tools to identify which barriers to change in behaviour are present, why these barriers exist, and what the optimal behaviour should be. In turn, this knowledge allows us to design interventions to help people make better decisions. The methods used are field, laboratory, and online experiments.
