We want to run an economic experiment and need internet users to be able to participate (we want to use Amazon Mechanical Turk to recruit participants). Using the app each participant should be able to make a series of 10 sequential decisions with monetary consequences. I have attached an image of something which was used a long while ago for a similar experiment. We want it to maintain the same functionality as in that one (your wealth, your decision, return profile, a button to draw, and then an outcome). The app must calculate all the amounts individually for each participant and for each of the 10 rounds. We would need to add some additional information to this basic design and wouldn't mind a more refined look to the app. We would need to be able to record each participant's information for each round (we want around 200 participants), so that we can then analyse and compare the amount (in percent and actual money) that each participant spent in every round, and as a whole.
