Speech by Governor Brainard via the Board of Governors of the Federal Reserve System, April 5:
....While national data do not directly disaggregate the differential effects of inflation by household income groups, a variety of evidence suggests that lower-income households disproportionately feel the burden of high inflation. Lower-income families expend a greater share of their income on necessities; have smaller financial cushions; and may have less ability to switch to lower-priced alternatives. Arthur Burns noted in the late 1960s that "there can be little doubt that poor people…are the chief sufferers of inflation."4
Today, inflation is very high, particularly for food and gasoline. All Americans are confronting higher prices, but the burden is particularly great for households with more limited resources. That is why getting inflation down is our most important task, while sustaining a recovery that includes everyone. This is vital to sustaining the purchasing power of American families.
Whose Cost of Living?
In assessing inflation faced by American consumers, economists and policymakers generally rely on the change in the consumer price index (CPI) or the change in the price index for personal consumption expenditures (PCE).5 Since January 2012, the Committee's price-stability goal has been specified as a longer-run goal of 2 percent in terms of annual PCE inflation.6 Both CPI and PCE inflation metrics are assembled from a collection of underlying elementary price indexes for narrow subsets of goods and services.7 The price changes each month for the goods and services in these subsets are combined into measures of overall inflation by calculating a weighted average of all these subindexes, where the weights are based on average aggregate consumer expenditures in each category.Using a national average of consumer expenditures to weight the categories has intuitive appeal. This measure is particularly useful, for example, in adjusting measures of overall expenditure for changes in prices to determine how much real growth has occurred between two periods. However, using a national average of expenditures to weight the categories has limitations when it comes to representing the true cost of living experienced by different types of households.
U.S. Households Have Different Inflation Experiences
Each household in the United States has a particular consumption bundle whose prices and quantities combine to make up that household's cost of living. If we could start with each individual household's cost of living and aggregate across households by giving equal weight to each household, it would create an economy-wide cost-of-living index. The change in such a cost-of-living index would represent the average inflation experienced by U.S. households. Instead, because the CPI and PCE indexes weight every dollar of expenditure equally, these indexes implicitly weight each household's cost of living proportionally to their total expenditure.8 Since lower-income households represent a relatively smaller share of overall expenditure, the inflation associated with their consumption baskets is underrepresented in the official consumer price indexes.First, low- and moderate-income households could experience inflation that diverges from the average because their consumption baskets differ systematically from the average. 10 Lower-income households spend 77 percent of their income on necessities—more than double the 31 percent of income spent by higher-income households on these categories.11
Several studies have found that the consumption baskets of lower-income households have experienced higher-than-average inflation rates over time. Research from the Bureau of Labor Statistics (BLS) has examined the effect of different consumption baskets by using the same elementary price indexes as used in the official CPI but assigning the weights of these components to reflect the consumption bundles of different types of households. A 2021 working paper by BLS staff based on data from 2003 to 2018 found that a price index reflecting the consumption basket for households in the lowest-income quartile grew faster than the overall CPI, while a price index reflecting the consumption basket for households in the highest-income quartile grew more slowly than the overall CPI.12 A 2015 BLS study found a similar result using data from 1982 to 2014.13 Of course, the recent sharp increases in inflation may have affected the consumption bundles of lower-income households relative to the average differently than in previous cycles.....
