Description

This dataset contains the research data associated with the preprint / working paper titled "Homo economicus or Homo rivalis: The Rival as a Reference Point in Economic Decision Making". The study investigates how the presence of a rival acts as a reference point and influences economic decision-making processes, challenging the classic neoclassical model of Homo economicus. Data overview: The dataset is provided in SPSS format (.sav) and includes responses from a nationwide Polish sample of 427 adults. Data was collected via the ePanel platform. The data covers the following main areas: 1. Demographics: Gender, age, education level, and place of residence. 2. Experimental variables (The Multi-Prospect Game): Decisions made by participants in a proprietary decision-making game. Participants assigned financial changes (from -500 PLN to +500 PLN) affecting both their own and their rival's outcomes, with a leverage mechanism where the rival's payoff changes by twice the amount. 3. Experimental conditions: The dataset includes participants' random assignment to conditions regarding the rival's initial status (winning vs. losing) and the rival's gender (male vs. female). 4. Derived indices: Calculated variables used in the manuscript, such as change in own winnings, difference from the rival's score, and strategy categorization (financial maximization, egalitarian, status maximization, status quo). Methodological notes: For a full description of the methodology, experimental design, and statistical analyses, please refer to the associated paper available on SSRN. Software requirements: The .sav file requires IBM SPSS Statistics (or compatible open-source software like R, PSPP, JASP, or jamovi) to be opened and analyzed.
