Experimental Design (Public)
|
Before
We will run short sessions (approximately 45 minutes) in which groups play three different treatments. Group sizes will be around 10-15 players.
After running short sessions, we also plan to run longer versions of the experiment. In these longer versions (between 1 day and 1 week), a larger number of players (60-100) will play a single treatment.
|
After
-Sessions run in NYU CESS, with each subject playing all treatments randomly ordered.
-Sessions run on Amazon Mechanical Turk with groups of 10 workers, each only playing one session.

Randomization Method
|
Before
Randomization done by computer. Some randomization will be done pre-session.

After
Randomization done by computer.

Randomization Unit
|
Before
Across sessions: randomize order of treatments
Within sessions: random matching of players
Within game: random order of parameter change
|
After
Session level - each group will be randomly assigned one treatment.

Planned Number of Clusters
|
Before
12 (short) sessions in NYU CESS
3 long sessions
|
After
12 sessions in NYU CESS (each session corresponding to three treatments)
~40 Sessions on MTurk (each session corresponding to 2, 3 or 4 treatments)

Planned Number of Observations
|
Before
200-700 players
|
After
~300 individuals in NYU CESS
~1250 individuals on Amazon Mechanical Turk

Sample size (or number of clusters) by treatment arms
|
Before
Each player in the short session plays all 3 treatments, randomly ordered.
3 clusters for large group experiments.
|
After
Each player in the NYU session plays all 3 treatments, randomly ordered.
On MTurk, each player plays just 1 treatment
