The Effect of a Change in Wages on Welfare in a Two–Class Monocentric City
研究了城市郊区富人工资上涨对中心区穷人福利的影响，发现通勤时间成本大于运营成本时，富人工资增加会损害穷人福利。
This paper performs a comparative static analysis to derive the effect of a change in the wages of the rich living in the suburban area of a city on the welfare of the poor living in the central area of the city. It assumes that commuting cost is a function of distance and wages. A sufficient condition for an increase in the wages of the rich to harm the welfare of the poor is that the time cost of commuting is greater than the operating cost of commuting.
