@AnthonyLeeZhang @wdiamond_econ Yeah I actually totally agree in the HK case (and in general, that the profit-maximizing quantity for the monopolist [here, local gov that controls zoning] is not the socially optimal quantity)
@AnthonyLeeZhang@wdiamond_econ是的，我实际上完全同意香港的情况（一般来说，垄断者（这里是控制分区的地方政府）利润最大化的数量不是社会最佳数量）
