The folder "Experiment Instructions" contains the instructions given to subjects in each of the experimental treatments, across all 3 experiments (Experiment 1, Experiment 2, Experiment 3).

###############################################

The folder "ztree programs" contains the .ztt files used to run the experimental sessions for all 3 experiments (Experiment 1, Experiment 2, Experiment 3).

###############################################

Scripts to analyze the data and produce the tables and figures included in the manuscript are given in the "Data Analysis" folder. The folder contains 4 .R files and 1 .xlsx file:

"Exp1_Analysis.R" contains the R code for results reported for Experiment 1 (MAIN). This includes Tables 2-5 and Figures 1-8.
>> To run Exp1_Analysis.R, one can use the data found in Sheet 1 ("DATA - MAIN") of the "COI MgtSci DATA.xlsx" file.
>> Note: While "Exp1_Analysis" was used to calculate the stats for Figures 1 and 6, the figures themselves were created in Excel. See "Fig1_Fig6.xlsx" for these two figures (Figure 1 shown in sheet 1, Figure 6 shown in sheet 2).

"Exp2_Analysis.R" contains the R code to produce all results reported for Experiment 2 (INEQUALITY AVERSION). This includes Table 6.
>> To run Exp2_Analysis.R, one can use the data found in Sheet 3 ("DATA - IA") of the "COI MgtSci DATA.xlsx" file.

"Exp3_Analysis.R" contains the R code to produce all results reported for Experiment 3 (REPEATED). This includes Table 7.
>> To run Exp3_Analysis.R, one can use the data found in Sheet 5 ("DATA - REP") of the "COI MgtSci DATA.xlsx" file.
>> When reporting the Experiment 3 results, we also provide a comparison with the Experiment 1 results (T3/T4 only). So, the Experiment 1 data found in Sheet 1 ("DATA - MAIN") of the "COI MgtSci DATA.xlsx" file is also needed.

"OnlineAppx_Analysis.R" contains the R code to produce all results reported in the online appendix. This includes Tables A1-A6 and Figures A1-A2.
>> To run OnlineAppx_Analysis.R, one can use the data found in Sheets 1 ("DATA - MAIN") and 5 ("DATA - REP") of the "COI MgtSci DATA.xlsx" file.
