All sequential allotment rules are obviously strategy‐proof
研究了单峰偏好下的分配问题，证明所有顺序分配规则（一类防策略且高效的规则）都是明显防策略的，表明在此设定下明显防策略性并不比防策略性更严格。
For division problems with single‐peaked preferences, we show that all sequential allotment rules, a large subfamily of strategy‐proof and efficient rules, are also obviously strategy‐proof. Although obvious strategy‐proofness is, in general, more restrictive than strategy‐proofness, this is not the case in this setting.
