Conditions of Partisan Optimum

The conditions of Partisan optimum are given below of products to be optimal must be such as to make it  impossible for any pair of individuals to exchange any quantity of any pair of co user goods reselling in increase in one satisfaction shout decreasing that of another. That is if any Al native allocation can  increase one one’s sat without decreasing  another’s it is not optimal To in terms of   indifference curve technique, the final rate of substitution  (MRS) between ans two us be same for  any pair of owners of the goods. We know  that marginal rate of MRS is tile rate at   which units of one g hanged fort he units of another without tel f satisfaction.
