This study investigates efficient and strategy‐proof mechanisms for allocating indivisible goods under constraints. First, we examine a setting without endowments. In this setting, we introduce a class of constraints-ordered accessibility-for which the serial dictatorship (SD) mechanism is...

This paper contains two results. The first result says that given any efficient non-monetary allocation there is a balanced vector of transfers so that the resulting allocation is fair. The second result says that given any efficient non-monetary allocation there is a pricing function defined on...
