At the Koch Foundation we played the ‘Bag game’ – each participant received a brown bag containing 2 gifts (stocking fillers from a dollar store) and were asked to rate their satisfaction. We were then allowed to trade, and were asked again. It demonstrated how trade creates value, and you could see economic institutions – money, markets, reputation effects etc all emerge. Fantastic stuff.
