Welcome!


I am a Senior Research Fellow (Postdoc) at the Max Planck Institute for Research on Collective Goods (Experimental Economics Group).

I am an applied microeconomist specialized in behavioral and experimental economics.  My research mainly focuses on understanding the foundations of prosocial, cooperative, and moral behavior.

I hold a PhD from the Bonn Graduate School of Economics (BGSE).

Working Papers

Personal Norms And Not Only Social Norms Shape Economic Behavior, revision requested at Management Science
(with Eugenio Verrina)

Abstract: We propose a simple utility framework and design a novel two-part experiment to study the relevance of personal norms across various economic games and settings. We show that personal norms — together with social norms and monetary payoff — are highly predictive of individuals’ behavior. Moreover, they are: i) distinct from social norms across a series of economic contexts, ii) robust to an exogenous increase in the salience of social norms, and iii) complementary to social norms in predicting behavior. Our findings support personal norms as a key driver of economic behavior.

 The Roots of Cooperation
(with Parampreet C. Bindra, Daniela Glätzle-Rützler, Angelo Romano, Matthias Sutter, and Claudia Zoller)

Abstract: We study the development of cooperation in 929 young children, aged 3 to 6. In a unified experimental framework, we examine pre-registered hypotheses about which of three fundamental pillars of human cooperation – direct and indirect reciprocity, and third-party punishment – emerges earliest as a means to increase cooperation in a repeated prisoner’s dilemma game. We find that third-party punishment doubles cooperation rates in comparison to a control condition. Children also reciprocate others’ behavior, yet direct and indirect reciprocity do not increase overall cooperation rates. We also examine the influence of children’s cognitive skills and parents’ socioeconomic background on cooperation. 

Work in Progress

Heterogeneity in Effort Provision: Evidence From a Lab-in-the-Field Experiment
(with Stefania Bortolotti, Daniel Salicath, Stefan Schmidt, Sebastian Schneider, and Matthias Sutter; preregistered at AEA RCT Registry)

Short summary: We conduct a large-scale study in German high schools with more than 1900 subjects  to investigate the heterogenous effects of incentive schemes across different types of individuals.

Social Identity and Systematic Biases
(with Eugenio Verrina and Stefan Schmidt)

Short summary:  Selection bias, correlation neglect, and confirmation bias commonly appear in information structures where social identity motives are present. We study how social identity and the three biases together affect belief formation.

Personal Norms, Social Norms, and Political Preferences
(with Eugenio Verrina)

Short summary:  We study how political preferences relate to the patterns of personal and social norms as well as to the weight placed on them in the decision-making process.

Self-image, Social Image, and Prosocial Behavior
(with Armin Falk and Simone Quercia)

Short summary: We design symmetric maniplatutions of self and social image concerns and investigate their effect on prosocial behavior in a dictator game (n = 531). To do so, we exogenously increase self-awareness and observability, directing a person's focus on their private and public selves, respectively. 

Quantitative Patterns of Cooperation in Social-Dilemma Experiments with Minimum Identifiability
(with Yini Geng, Ivan Romić, Lei Shi, Eizo Akiyama, Matjaž Perc, Zhen Wang, and Marko Jusup)

Short summary: In a study conducted across 3 countries, we investigate how minimal information one's gender in an otherwise anonymous setup affects cooperative behavior in a repeated prisoner's dilemma game.
