当城市通过了限制房东对公寓收取租金的法律时,这些法律通常适用于已有的房屋,而不适用于任何还没有建筑的房
When cities pass laws limiting the rent landlords can charge on apartments, the laws usually apply to existing buildings and exempt any buildings not yet built. Advocates of rent control argue that this exemption ensures that rent control does not discourage the construction of new housing. Evaluate this argument in light of the time-inconsistency problem.
