Metropolitan Land Values
首次估算了美国所有大都市区基于交易的土地价值指数，发现城市中心土地价值随城市规模增长，且城市间差异显著，五大城市群占全美城市土地价值的48%。
We estimate the first cross-sectional index of transaction-based land values for every U.S. metropolitan area. The index accounts for geographic selection and incorporates novel shrinkage methods using a prior belief based on urban economic theory. Land values at the city center increase with city size, as do land-value gradients; both are highly variable across cities. Urban land values are estimated at more than two times GDP in 2006. These estimates are higher and less volatile than estimates from residual (total - structure) methods. Five urban agglomerations account for 48% of all urban land value in the United States.
