有無有可以話我知咩叫 Pareto Efficiency ???

pareto efficiency ,this is ,
it is impossible to make one better off without making one worse off.

用中文講 ,即係當經濟去到一個地步 ,
冇辦法令到一個人得益而又唔令到另一個人受損 ,
咁就達到pareto efficiency.

不過actually ,我地都好難去到哩個地步.

下... 咁樣唔係叫 Pareto inefficient 咩...

Given a set of alternative allocations of, say, goods or income for a set of individuals, a movement from one allocation to another that can make at least one individual better off without making any other individual worse off is called a Pareto efficient.
