摘要：Interest in classroom experiments and games continues to grow. The previous special issue of IREE wastestament to this trend and several papers in the current issue feature classroom experiments orgames. Two of these papers, one by Moore and the other by Rigall‐I‐Torrent, are about Cournot gamesfor intermediate microeconomics. Cournot games can help students to see the relationships betweenthe alternative market structures, in particular that between oligopoly and monopoly, and can providea useful introduction to game theory. Rigall‐I‐Torrent shows how this can be done by setting up aCournot game with increasing complexity. In Moore’s game, the typical textbook model of costs isextended in order to show that colluding firms do not necessarily behave like a monopolist as they do inthe typical model. Damianov and Sanders describe an experiment that shows how the pursuit ofpositional goods by individuals in order to signal their relatively high income is socially sub‐optimal, andthat mechanisms for publicly disclosing their income would allow a Pareto improvement. Students areencouraged to explore implications for public policy.
