Large games: Fair and stable outcomes
We establish that for a broad class of large games with sidepayments, fair outcomes are nearly stable. More precisely, the Shapley value of a large game is in the \(\epsilon\)-core and \(\epsilon\) is very small if the game is very large. The proof uses two other results of independent interest: for large games the power of improvement is concentrated in small coalitions, and the Shapley value of a small syndicate acting together is nearly the sum of the Shapley values which accrue to the members acting alone.
