INFLATION INEQUALITY IN THE UNITED STATES
研究了1987-2000年间美国家庭面临的不同通胀率，发现老年人因医疗支出、穷人因汽油价格波动而承受更高生活成本，但高通胀在家庭间并不持续。
Different spending patterns across households and differences in price increases across goods and services lead to unequal levels of inflation faced by different households. In this paper we measure the degree of inequality in inflation across U.S. households for the period 1987–2000. The broad picture that emerges from our results is that over our whole sample period there are substantial differences in the inflation experiences across U.S. households. We find that the cost of living increases were generally higher for the elderly, in large part because of their health care expenditures, and that the cost of living of poor households is most sensitive to the, historically large, fluctuations in gasoline prices. Still, when looking at the whole population, we find that individual households that are confronted with high inflation in one year do not generally face high inflation in the subsequent year as well.
