
MBA-style combination of information economics and twosided market concepts

Based on lectures, cases

Lots of part-time sections, 3.5h late evening sessions

Needed an additional resource to bring concepts to life


Student teams compete against each other in a series of stylized settings that simulate elements of competition in digital markets

Played at beginning of each weekly session, 40-50 minutes to complete

Allow teams of students to teach digital market concepts to each other

Build excitement and curiosity that stimulates learning


Each game is played on a spreadsheet that’s displayed on the projection screen and available to all students

Game has 5-6 rounds

On each round each team has 3-5 minutes to make a relatively simple decision (about the current round’s prices, investments, etc.)

After each round, instructors collect all responses, plug them into spreadsheet and briefly comment

Initially, each group has 10 suppliers and 100 consumers.
In each round you release a new version; you are able to sell new releases of the software to all existing customers (suppliers and consumers).
In each round your group will charge two prices: one price for the supplier and another price for the consumer.
The supplier and buyer price shall be an integer from $0 to $40.
Assume the average cost (think of it as SG&A) for each customer (suppliers and consumers) is $10.
The goal of this game is to have the largest cumulative profit after 5 rounds.
