We find that full efficiency is not achieved in the experiment with or without naive traders, and efficiency … experiment participants, and that allowing face-to-face pre-play communication increases efficiency although still not to the …

Using a lab experiment, we investigate the real-life performance of envy-free and proportional cake-cutting procedures … with respect to fairness and preference manipulation. We nd that envy-free procedures, in particular Selfridge-Conway, are … manipulate them. Our results support the practical use of the celebrated Selfridge-Conway procedure, and more generally, of envy …
