We propose a new method to estimate the empirical pricing kernel based on option data. We estimate the pricing kernel …-neutral density is approximated by a weighted kernel density estimator with varying unknown weights for di erent observations, and the … subjective density is approximated by a kernel density estimator with equal weights. We represent the European call option price …

-assignment optimization problems. It is known that for permutation games the bargaining set and the core coincide, consequently, the kernel is … a subset of the core. We prove that for permutation games the kernel is contained in the least core, even if the latter … game is also an example (of minimum size) for a game with a non-convex kernel. …
