Given some endowment in an Edgeworth box, the contract curve is the individually rational subset of the Pareto set. In other words, it is the set of Pareto efficient allocations in an economy. Also, any Walrasian equilibrium lies in the contract curve of the Pareto set.

On the contract curve, the marginal rate of substitution is the same for both agents.
