Euro area “lowflation” becomes “deflation”

Inflation in the euro area is measured by the Harmonized Index of Consumer Prices (HICP). “Price stability is defined as a year-on-year increase in the Harmonised Index of Consumer Prices for the euro area of below 2%” (the red horizontal line). The Governing Council of the ECB clarified that this target should be interpreted as “below, but close to, 2% over the medium term.” In the euro area, as in several other advanced economies, inflation was below target but above zero for about two years (see Contessi, De Pace, Li, 2014). The IMF recently defined this environment as “lowflation.”

The most recent measurements for the euro area have shown mild deflation, with year-on-year inflation rates slightly below zero. Most recently, low inflation rates across many countries have been due to a combination of economic slack in the global economy and low oil prices. The weak economic conditions in the euro area are an additional factor pushing its inflation rates even lower.

How this graph was created: Search for “Harmonized CPI,” and the series shown here should appear first in the list. Change units to “Percent Change from Year Ago.” To add the red horizontal line, use the new feature in FRED to create a user-defined line: Open the “ADD DATA SERIES” panel, select “Trend Line,” and change both the start and end values to 2.

The sound and fury of gasoline prices

Gasoline prices have really gone up and down lately. With such wide-ranging short-term fluctuations, it’s hard to tell whether gasoline has become more expensive over the long run. So we turn to FRED. The CPI includes a component that tracks gasoline used for private transportation. We can compare this gasoline component with the CPI to see how gasoline prices have risen in relation to prices in general. The graph clearly shows all the stormy fluctuations for gasoline. But it also clearly shows something we may not have expected: The price of gasoline is now at the same level it would have reached had it simply followed the smooth evolution of the overall price index. We can’t depend on these price levels to coincide, of course, given the typical fluctuations of gasoline. And if the past decade is any indication of the future, gasoline prices will return to their higher levels.

How this graph was created: Search for “CPI gasoline” and select the monthly seasonally adjusted series. Then add the series “CPI.” (You can also work from the relevant release table to select the series you want.) Finally, to start the series at the same level instead of the 1982-84 index year, edit both series as follows: Choose “Index (Scale value to 100 for chosen period)” under Units and “1967-01-01” under Observation Date.

The evolution of income inequality

Do you know that FRED includes data on income inequality? The data come from the income, poverty, and health insurance coverage release from the U.S. Census Bureau as part of its yearly Current Population Survey. The data cover both households and families, with geographic and racial subcategories. Do you also know the distinction between “households” and “families”? A household includes all people living in a housing unit; a family includes only those related by marriage, blood, or adoption.

The Gini ratios shown in this graph measure income inequality. Higher values indicate more inequality, and the graph clearly shows an upward trend for both households and families.

How this graph was created: Go to the release noted above, choose “gini” in the tags, choose the series you want to graph, and click “Add to graph.”
