 Fractional Pareto efficiency

Fractional Pareto efficiency is a concept that extends the traditional notion of Pareto efficiency in economics and optimization theory. While a traditional Pareto efficient allocation occurs when it is impossible to make one individual better off without making another individual worse off, fractional Pareto efficiency introduces a more nuanced approach. In fractional Pareto efficiency, one assesses configurations where some individuals may be partially made better off without entirely disadvantaging others.
