I consider an underexplored possible explainer of the "surprising" results of Ultimatum Game experiments, namely, that Proposers and Recipients consider following only some of all the logically possible strategies of their Ultimatum Game. I present an evolutionary analysis of different games...

Deliberative decision-making is often proposed as a mechanism to mitigate polarization in democratic processes. However, empirical evidence remains mixed, with some studies suggesting that deliberation among like-minded individuals can drive preference shifts toward extremes. We use a...

A war consists of multiple battles, yet the theoretical literature of International Relations has given little attention to how battles relate within a war. By integrating two ultimatum games with private information played by an Aggressor and a Defender, we develop bargaining models of war with...

Fairness in competitive games such as the Ultimatum Game is often defined theoretically. According to some of the literature, in which fairness is determined only based on resource allocation, a proposal splitting resources evenly (i.e., 5:5) is generally assumed as fair, and minimal deviation...

Using a large-scale incentivized trust game experiment conducted across all 27 EU member states, we find that sexual minorities exhibit greater prosocial behaviour toward another vulnerable group but not toward an unknown counterpart, compared to heterosexual individuals. The observed effects...

This paper studies the influence of moral emotions and beliefs on understanding charitable giving. While specific moral emotions such as empathy, guilt, and shame have been associated with prosocial behavior, how they impact giving behavior may depend on beliefs about the giving of others. Using...

We investigate if Large Language Models (LLMs) exhibit personality-driven strategic behavior in the Ultimatum Game by manipulating Dark Factor of Personality (D-Factor) profiles via standardized prompts. Across 400k decisions from 17 open-source models and 4,166 human benchmarks, we test whether...

Why do people punish experienced unfairness if it induces costs for both the punisher and punished person(s) without any direct material benefits for the punisher? Economic theories of fairness propose that punishers experience disutility from disadvantageous inequality and punish in order to...

We implement a binary trust game between 211 married couples from lowincome households in urban India. In a separate experiment, these spouses randomly received either only a joint savings device (control) or, additionally, a device for individual usage (treatment). Combining data from both...

In prosocial decisions, decision-makers are inherently uncertain about how their decisions impact others’ utility – we call this interpersonal uncertainty. We show that people’s response to interpersonal uncertainty shapes well-known patterns of prosocial behavior. First, using standard...

In prosocial decisions, decision-makers are inherently uncertain about how their decisions impact others' utility - we call this interpersonal uncertainty. We show that people's response to interpersonal uncertainty shapes well-known patterns of prosocial behavior. First, using standard social...

Experiments are an important tool in economic research. However, it is unclear to which extent the control of experiments extends to the perceptions subjects form of such experimental decision situations. This paper is the first to explicitly elicit perceptions of the dictator and trust game and...

The Rwandan government emphasizes the role of cooperatives in transforming rural economies from subsistence farming to diversified commercial agriculture, including high-value export horticultural crops. The success of these cooperatives depends significantly on farmers' willingness to join and...

An extensive literature documents that people are willing to sacrifice personal material gain to adhere to a moral motive. However, less is known about the psychological mechanisms that operate when two moral motives come into conflict. We hypothesize that individuals adhere to the moral motive...

Principal-agent interactions in which the agent can preemptively signal prosociality can achieve higher levels of trust and reciprocity if both parties care about social esteem (Boulu-Reshef and Kuechle, 2023). However, it is unclear to what extent social esteem is necessary for this outcome. In...

Gender differences have frequently been studied in experimental economics, but the findings remain inconclusive. In this study, we focus on gender differences in expectations and economic behavior in a dictator game, building on Blanckenburg, Iseke and Tebbe (2023). We add to prior work by...

In a recent simulation study, Goodman et al. (2019) compare several methods with regard to their type I and type II error rates when considering a thick null hypothesis that includes all values that are practically equivalent to the point null hypothesis. They propose a hybrid decision criterion...
