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