Experimental Design

Experimental Design
Principals review a number of scenarios in which an agent had to make a choice between two lotteries.The outcome of the agent’s choice determines the payoff of the principal, but not that of the agent, at least not directly. Principals decide whether they want to award a fixed bonus to the agent who took the decision, or to another, randomly chosen, participant.
Experimental Design Details
There are two treatments. In the OB treatment, principals observe both the outcome and the decision before deciding on whether to award the bonus to the agent. In the no-OB (NOB) treatment, principals observe only the agents’ choices, but not their outcomes prior to the bonus decision. For a description of the decision tasks involved, see the pdf "design_analysis".

Experiment Characteristics

Sample size: planned number of clusters
The target number of participants is 50 principals and 1 or 2 agents per treatment (for the sake of incentivization only). The target number of 50 observations refers to subjects who have not been excluded from the data analysis. For a description of the exclusion criteria, see the pdf "design_analysis".
Sample size: planned number of observations

Sample size (or number of clusters) by treatment arms

Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
