Prior work
This trial is based on or builds upon one or more prior RCTs.
Inequality is often inherited: individuals are not involved in the process that generates inequality, yet end up with different amounts of resources or opportunities based solely on relations to other people. We have previously conducted an online survey experiment with
a broadly representative sample of the US population to study individuals' redistributive preferences in situations featuring inherited inequality. This first study has been preregistered at the AEA RCT Registry (RCT ID: AEARCTR-0007948) and can be accessed here: We now plan to conduct a second replication study which includes some methodological improvements.
Details presented in the pre-analysis plan.

Experimental Design

Experimental Design
We conduct an online experiment to investigate attitudes towards inherited inequality among a broadly representative sample of the US population. The experiment builds on the impartial spectator paradigm (Cappelen et al., 2013), where impartial spectators can redistribute money between pairs of participants who received their initial payoffs either based on their relative performance on a real effort task or based on a random draw prior to the redistribution stage. We extend this paradigm by allowing active participants to not only generate a payoff for themselves but also for an associated passive counterpart who inherits a payoff. We are particularly interested in how spectators redistribute between passive participants, and how these decisions relate to spectators' preferences over real-world institutions and policies.

Experiment Characteristics

Sample size: planned number of clusters
We aim at n=550 spectators making redistribution decisions.
Sample size: planned number of observations
550 spectators, 5x4=20 common redistribution decisions per spectator => 11000 redistribution decisions in total.
Sample size (or number of clusters) by treatment arms
We aim at n=550 spectators making redistribution decisions.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
