Devotees of Z/Yen's S.B. Lady Daphne networking trips know that no trip is complete without an "icebreaker" game. This year is no exception and we've been working hard at this year's new offering. Our games have ranged from our "Boating Bourses" to "OligopoLuedo" and "Smugglers' Choice". All of the games have a rigorous theoretical underpinning and help to elucidate things such as Prospect Theory or the Prisoners' Dilemma. For the past few months we've been working with Mike Young and Geoff Buckingham of Corda, part of BAE Systems, on a joint venture game that helps people to understand negotiation in the context of cooperation on reducing carbon emissions.
