Simulation

In simulation folder, Experiment.py is main function for simulation test. Use following command to run experiments. MDPenvironment.py, Agent.py, Principal.py , are for environments, agent models and principal models. Simulation results is stored in simulation/results folder.

python Experiment.py baseline # baseline test
python Experiment.py reward_modify # reward function modification test
python Experiment.py action_nudge # action nudge test

Human subject experiment

We recruit 300 individual workers from Amazon Mechanical Turk. Experiment data is stored in human-subject-experiment/mturk-experiment-data.csv:

• uid represents anonymous workers, from 0 to 299
• treatment treatment of the worker, from 0-2 (0-baseline, 1-reward function modification, 2-action nudge)
• test_idx test order of games, 6 integers from 0 to 5
• data actions (worker moves) in each game, first is in test game (not included in test_idx)
• scores scores in each game, first is in test game (not included in test_idx)

Experiment setting is stored in human-subject-experiment/experiment-setting in forms of .json.
