Schema: CREATE TABLE table_name_41 (monotone VARCHAR, clone_independence VARCHAR, pareto_efficiency VARCHAR, non_dictatorship VARCHAR)
Question: what is the monotone when pareto efficiency is yes, non-dictatorship is yes, and clone independence is yes?
SQL: SELECT monotone FROM table_name_41 WHERE pareto_efficiency = "yes" AND non_dictatorship = "yes" AND clone_independence = "yes"
