伦敦房价呈幂律分布
London house prices are power-law distributed
摘要:
我们探讨了英国城市伦敦,曼彻斯特,布里斯托尔,纽卡斯尔,伯明翰和利兹的房价分布。我们发现帕累托(幂律)的行为在他们的上尾,这是明显不同的对数正态分布和伽马分布的情况下,伦敦,曼彻斯特和纽卡斯尔。对于伦敦这个权力最低的城市来说,这与超级富豪的财富分配惊人地吻合。我们提出了一个基于帕累托指数和类似于基尼系数的住房财富不平等指数,并评论其可能的用途。
英文摘要:
We explore the house price distributions for the English cities of London, Manchester, Bristol, Newcastle, Birmingham and Leeds. We find Pareto (power law) behaviour in their upper tails, which is clearly distinct from lognormal and gamma distributions in the cases of London, Manchester and Newcastle. For London, the city with the lowest power, this is a striking match with that found in the wealth distribution of the super-rich. We propose an index of Housing Wealth Inequality based on the Pareto exponent and analogous to the Gini coefficient, and comment on its possible uses.
