ConG: Continuous-Time Games for Experimental Economics.
ConG is a suite of programs for running game theory based Economics experiments. Subjects interact in a graphical, game-like environment. Over the course of a period, subjects can continuously change and adapt their strategy in real-time. ConG includes several different types of payoff functions, including support for arbitrary symmetric bimatrix games. Also included are innovative strategy selectors to display a wealth of potential payoff information in a compact manner. Finally, ConG has support for running games in both continuous and discrete time, allowing a direct comparison between the two treatments.
ConG is developed by the LEEPS Lab, and funded through NSF grant SES-0925039. It is easy to use for both experimenters and subjects. Experiments are defined using a human editable CSV file, loadable in any spreadsheet editor. No installation is required, and a demo experiment can be launched within minutes. We invite you to try it for yourself, download the current version, and run some of the examples below.

Demo Experiments with ConG
The following are test experiments we invite you to run on a single (non-networked) computer. With these examples we hope to give you a feel for how ConG client and control windows work, and how the config CSV files change the experiment.
- Public Goods Game (Voluntary Contribution Mechanism) - A simple public goods game under various experimental configurations: CHAT-window communication, "canned-response" communication and no communication. Discrete time options, and of course continuous time.
- Prisoner's Dilemma - "A Continuous Dilemma" - 2x2 Bi-Matrix Game, Heat Map, Continuous & Discrete Time Treatments.
- Hawk Dove - "Separating the Hawks from the Doves" 2x2 Matrix Payoffs - Pure & Mixed Strategies - Heat-Map - Group Size & Population Matching.
Config Files & ConG
Running ConG in Your Lab
A Payoff Function is a mapping between subject's strategy set and their payoff. ConG currently supports the tractable configuration of the following payoff functions.
- "matrix2x2" Two Strategy (Bimatrix) - two-by-two symmetric game.
- Sum - Public Goods, Cournot - games in which subjects payoffs are a function on one's own strategy, and the strategy sum of other player's strategy.
- Payoff Functions to Come:
- Min, Bertrand Pricing - coming this spring.
- 3x3 Matrix, Rock-Paper-Scissors - spring 2012.
- Scripted Payoff Functions - very soon.
A Selector is the interface for an experiment. Each selector allows the subjects to change their strategy and receive information about the game state. Different experiments lend themselves to using particular selectors, while other selectors for a given experiment are illogical. Below is a list of all the selectors available, and the experiments which commonly use them. The following names are the exact names required in the csv in the selector column. These names must be exactly as they are here, or errors will occur.
- heatmap2d - Strategy chosen with heatmap. Strategy displayed in Y-axis, competing group strategy in X-axis. Payoffs displayed by "heat".
- bubbles - Strategy chosen by clicking along the x/y axis. Current payoff is the height of the your dot along the y axis.
- pure - Strategy chosen with radio buttons. Payoffs displayed in a matrix next to the selector.
Time Modes & Settings
- Continuous vs Discrete - a discussion of how ConG treats discrete and continuous games at an architectural level.
Additional Configuration Options
- Grouping - configuring groups in your experiment.
- Communication - options for Chat during your experiment.
- Tricky Config File Fields - list of, and detailed explanation of tricky config CSV file fields.
- ConG User License & Citation Info - create page, and refer to ZIP file for user license. Users of ConG must also cite Working Paper, which needs to be on page.
- Experimental Output - ConG experiments produce tick-data-logs. View examples of this output and simple econometrics.
- Agents - pre-experiment stress testing of your config.
