I just came across this free economic games website that is " free , ready to play, nothing to install, no need to register!" They have 12 different games to chose from. As an example: Industrial Organization Price discrimination, vertical differentiation and peak-load pricing Players take price and quantity decisions for an airline on a given route against a robot competitor. Illustrates notions such as marginal cost/average cost, variable cost/fixed cost, sunk cost, short-run/long-run cost, price discrimination (yield management), elasticity of demand, peak-load pricing... And eventually, players must choose whether or not to use vertical differentiation to soften competition. This is a classroom variant of the tutorial of our other game, airECONsim . There are also games involving game theory, introduction to microeconomics, public goods, and Cournot and Stackelberg Games. They are not the most glamourous, but they seem to be a good way to use games in economic class
