In [[game theory]], the '''core''' is the set of feasible allocations that cannot be improved upon by a subset (a ''coalition'') of the economy's consumers. A coalition is said to ''improve upon'' or ''block'' a feasible allocation if the members of that coalition are better off under another feasible allocation that is identical to the first except that every member of the coalition has a different consumption bundle that is part of an aggregate consumption bundle that can be constructed from publicly available technology and the initial endowments of each consumer in the coalition. | |||
An allocation is said to have the ''core property'' if there is no coalition that can improve upon it. The core is the set of all feasible allocations with the core property. | |||
==Origin== | |||
The idea of the core already appeared in the writings of {{harvtxt|Edgeworth|1881}}, at the time referred to as the ''contract curve'' {{harv|Kannai|1992}}. Even if [[John von Neumann|von Neumann]] and [[Oskar Morgenstern|Morgenstern]] considered it an interesting concept, they only worked with zero-sum games where the core is always ''empty''. The modern definition of the core is due to {{harv|Gillies|1959}}. | |||
==Definition== | |||
Consider a [[transferable utility]] [[cooperative game]] <math>(N,v)</math> where <math>N</math> denotes the set of players and <math>v</math> is the [[Game theory#Characteristic function form|characteristic function]]. An [[Imputation (game theory)|imputation]] <math>x\in\mathbb{R}^N</math> is dominated by another imputation <math>y</math> if there exists a coalition <math>C</math>, such that each player in <math>C</math> prefers <math>y</math>, formally: <math>x_i\leq y_i</math> for all <math>i\in C</math> and there exists <math>i\in C</math> such that <math>x_i<y_i</math> and <math>C</math> can enforce <math>y</math> (by threatening to leave the [[Glossary of game theory#Glossary|grand coalition]] to form <math>C</math>), formally: <math>\sum_{i\in C}y_i\leq v(C)</math>. An imputation <math>x</math> is ''dominated'' if there exists an imputation <math>y</math> dominating it. | |||
The '''core''' is the set of imputations that are not dominated. | |||
==Properties== | |||
* Another definition, [[Logical equivalence|equivalent]] to the one above, states that the core is a set of payoff allocations <math>x\in\mathbb{R}^N</math> satisfying | |||
#Efficiency: <math>\sum_{i\in N}x_i=v(N)</math>, | |||
#Coalitional rationality: <math>\sum_{i\in C}x_i\geq v(C)</math> for all subsets (coalitions) <math>C\subseteq N</math>. | |||
* The core is always well-defined, but can be [[empty set|empty]]. | |||
* The core is a set which satisfies a system of weak [[linear]] inequalities. Hence the core is [[Closed set|closed]] and [[Convex set|convex]]. | |||
* The [[Bondareva–Shapley theorem]]: The core of a game is nonempty [[iff]] the game is "balanced" ({{harvnb|Bondareva|1963}},{{harvnb|Shapley|1967}}). | |||
* Every [[Walrasian equilibrium]] has the core property, but not ''vice versa''. The [[Edgeworth conjecture]] states that, given additional assumptions, the limit of the core as the number of consumers goes to infinity is a set of Walrasian equilibria. | |||
* Let there be ''n'' players, where ''n'' is odd. A game that proposes to divide one unit of a good among a coalition having at least (''n''+1)/2 members has an empty core. That is, no stable coalition exists. | |||
==Example== | |||
===Example 1: Miners=== | |||
Consider a group of ''n'' miners, who have discovered large bars of gold. If two miners can carry one piece of gold, then the payoff of a coalition ''S'' is | |||
:<math>v(S) = \begin{cases} |S|/2, & \text{if }|S|\text{ is even}; \\ (|S|-1)/2, & \text{if }|S|\text{ is odd}. \end{cases}</math> | |||
If there are more than two miners and there is an even number of miners, then the core consists of the single payoff where each miner gets 1/2. If there is an odd number of miners, then the core is empty. | |||
===Example 2: Gloves=== | |||
Mrs A and Mrs B are knitting gloves. The gloves are one-size-fits-all, and two gloves make a pair that they sell for €5. They have each made three gloves. How to share the proceeds from the sale? The problem can be described by a [[Game theory#Characteristic function form|characteristic function form]] game with the following characteristic function: Each lady has three gloves, that is one pair with a market value of €5. Together, they have 6 gloves or 3 pair, having a market value of €15. Since the singleton coalitions (consisting of a single lady) are the only non-trivial coalitions of the game all possible distributions of this sum belong to the core, provided both ladies get at least €5, the amount they can achieve on their own. For instance (7.5, 7.5) belongs to the core, but so does (5, 10) or (9, 6). | |||
===Example 3: Shoes=== | |||
For the moment ignore shoe sizes: a pair consists of a left and a right shoe, which can then be sold for €10. Consider a game with 2001 players: 1000 of them have 1 left shoe, 1001 have 1 right shoe. The core of this game is somewhat surprising: it consists of a single imputation that gives 10 to those having a (scarce) left shoe, and 0 to those owning an (oversupplied) right shoe. | |||
We verify that this is indeed the case. Observe that any pair having a left and a right shoe can form a coalition and sell their pair for €10, so any pair getting less than that will block the imputation. So if an imputation is in the core, we can write down left-right pairs and any of these pairs will get at least 10, in fact, exactly 10, since on the end we can only sell 1000 pairs, making the total budget equal to 10000. This leaves a right-shoe owner with 0 payment. Now go through the pairs: if there is a left-shoe owner who has less than 10, say 8, then it can join this poor player, sell their shoes, give him 1, and keep 9 to herself. This way both are better off. For stability such a left-shoe owner cannot exist: all left shoe owners get already 10. | |||
The message remains the same, even if we increase the numbers as long as left shoes are scarcer. The core has been criticized for being so extremely sensitive to oversupply of one type of player. | |||
==The core in general equilibrium theory== | |||
The Walrasian equilibria of an exchange economy in a general equilibrium model, will lie in the core of the cooperation game between the agents. Graphically, and in a two-agent economy (see Edgeworth Box), the core is the set of points on the contract curve (the set of Pareto optimal allocations) lying between each of the agents' indifference curves defined at the initial endowments. | |||
==The core in voting theory== | |||
When alternatives are allocations (list of consumption bundles), it is natural to assume that any nonempty subsets of individuals can block a given allocation. | |||
When alternatives are public (such as the amount of a certain public good), however, it is more appropriate to assume that only the coalitions that are large enough can block a given alternative. The collection of such large ("winning") coalitions is called a ''simple game''. | |||
The ''core of a simple game with respect to a profile of preferences'' is based on the idea that only winning coalitions can reject an alternative <math>x</math> in favor of another alternative <math>y</math>. A necessary and sufficient condition for the core to be nonempty for all profile of preferences, is provided in terms of the [[Nakamura number]] for the simple game. | |||

In game theory, the core is the set of feasible allocations that cannot be improved upon by a subset (a coalition) of the economy's consumers. A coalition is said to improve upon or block a feasible allocation if the members of that coalition are better off under another feasible allocation that is identical to the first except that every member of the coalition has a different consumption bundle that is part of an aggregate consumption bundle that can be constructed from publicly available technology and the initial endowments of each consumer in the coalition.
An allocation is said to have the core property if there is no coalition that can improve upon it. The core is the set of all feasible allocations with the core property.
Origin
The idea of the core already appeared in the writings of Template:Harvtxt, at the time referred to as the contract curve Template:Harv. Even if von Neumann and Morgenstern considered it an interesting concept, they only worked with zero-sum games where the core is always empty. The modern definition of the core is due to Template:Harv.
Definition
Consider a transferable utility cooperative game where denotes the set of players and is the characteristic function. An imputation is dominated by another imputation if there exists a coalition , such that each player in prefers , formally: for all and there exists such that and can enforce (by threatening to leave the grand coalition to form ), formally: . An imputation is dominated if there exists an imputation dominating it.
The core is the set of imputations that are not dominated.
Properties
- Another definition, equivalent to the one above, states that the core is a set of payoff allocations satisfying
- Efficiency: ,
- Coalitional rationality: for all subsets (coalitions) .
- The core is always well-defined, but can be empty.
- The core is a set which satisfies a system of weak linear inequalities. Hence the core is closed and convex.
- The Bondareva–Shapley theorem: The core of a game is nonempty iff the game is "balanced" (Template:Harvnb,Template:Harvnb).
- Every Walrasian equilibrium has the core property, but not vice versa. The Edgeworth conjecture states that, given additional assumptions, the limit of the core as the number of consumers goes to infinity is a set of Walrasian equilibria.
- Let there be n players, where n is odd. A game that proposes to divide one unit of a good among a coalition having at least (n+1)/2 members has an empty core. That is, no stable coalition exists.
Example
Example 1: Miners
Consider a group of n miners, who have discovered large bars of gold. If two miners can carry one piece of gold, then the payoff of a coalition S is
If there are more than two miners and there is an even number of miners, then the core consists of the single payoff where each miner gets 1/2. If there is an odd number of miners, then the core is empty.
Example 2: Gloves
Mrs A and Mrs B are knitting gloves. The gloves are one-size-fits-all, and two gloves make a pair that they sell for €5. They have each made three gloves. How to share the proceeds from the sale? The problem can be described by a characteristic function form game with the following characteristic function: Each lady has three gloves, that is one pair with a market value of €5. Together, they have 6 gloves or 3 pair, having a market value of €15. Since the singleton coalitions (consisting of a single lady) are the only non-trivial coalitions of the game all possible distributions of this sum belong to the core, provided both ladies get at least €5, the amount they can achieve on their own. For instance (7.5, 7.5) belongs to the core, but so does (5, 10) or (9, 6).
Example 3: Shoes
For the moment ignore shoe sizes: a pair consists of a left and a right shoe, which can then be sold for €10. Consider a game with 2001 players: 1000 of them have 1 left shoe, 1001 have 1 right shoe. The core of this game is somewhat surprising: it consists of a single imputation that gives 10 to those having a (scarce) left shoe, and 0 to those owning an (oversupplied) right shoe.

So if an imputation is in the core, we can write down left-right pairs and any of these pairs will get at least 10, in fact, exactly 10, since on the end we can only sell 1000 pairs, making the total budget equal to 10000. This leaves a right-shoe owner with 0 payment. Now go through the pairs: if there is a left-shoe owner who has less than 10, say 8, then it can join this poor player, sell their shoes, give him 1, and keep 9 to herself. This way both are better off. For stability such a left-shoe owner cannot exist: all left shoe owners get already 10.
The message remains the same, even if we increase the numbers as long as left shoes are scarcer. The core has been criticized for being so extremely sensitive to oversupply of one type of player.
The core in general equilibrium theory
The Walrasian equilibria of an exchange economy in a general equilibrium model, will lie in the core of the cooperation game between the agents. Graphically, and in a two-agent economy (see Edgeworth Box), the core is the set of points on the contract curve (the set of Pareto optimal allocations) lying between each of the agents' indifference curves defined at the initial endowments.
The core in voting theory
When alternatives are allocations (list of consumption bundles), it is natural to assume that any nonempty subsets of individuals can block a given allocation. When alternatives are public (such as the amount of a certain public good), however, it is more appropriate to assume that only the coalitions that are large enough can block a given alternative. The collection of such large ("winning") coalitions is called a simple game. The core of a simple game with respect to a profile of preferences is based on the idea that only winning coalitions can reject an alternative in favor of another alternative . A necessary and sufficient condition for the core to be nonempty for all profile of preferences, is provided in terms of the Nakamura number for the simple game.
