Center node: "equilibria of generalized cut and choose protocols"
  Abstract: Classic cake cutting protocols -- which fairly allocate a divisible good among agents with heterogeneous preferences -- are susceptible to manipulation. Do their strategic outcomes still guarantee fairness? To answer this question we adopt a novel algorithmic approach, proposing a concrete computational model and reasoning about the game-theoretic properties of algorithms that operate in this model. Specifically, we show that each protocol in the class of generalized cut and choose (GCC) protocols -- which includes the most important discrete cake cutting protocols -- is guaranteed to have approximate subgame perfect Nash equilibria. Moreover, we observe that the (approximate) equilibria of proportional protocols -- which guarantee each of the n agents a 1/n-fraction of the cake -- must be (approximately) proportional, and design a GCC protocol where all Nash equilibrium outcomes satisfy the stronger fairness notion of envy-freeness. Finally, we show that under an obliviousness restriction, which still allows the computation of approximately envy-free allocations, GCC protocols are guaranteed to have exact subgame perfect Nash equilibria.
