Inflation measures how much more expensive a set of goods and services has become over a certain period, usually a year It may be one of the most familiar words in economics. Inflation has plunged countries into long periods of instability. Central bankers often aspire to be known as “inflation hawks.” Politicians have won elections with promises to combat inflation, only to lose power after failing to do so. Inflation was even declared Public Enemy No. 1 in the United States—by President Gerald Ford in 1974.

What, then, is inflation, and why is it so important? Inflation is the rate of increase in prices over a given period of time. Inflation is typically a broad measure, such as the overall increase in prices or the increase in the cost of living in a country. But it can also be more narrowly calculated—for certain goods, such as food, or for services, such as a haircut, for example. Whatever the context, inflation represents how much more expensive the relevant set of goods and/or services has become over a certain period, most commonly a year. Consumers’ cost of living depends on the prices of many goods and services and the share of each in the household budget.

To measure the average consumer’s cost of living, government agencies conduct household surveys to identify a basket of commonly purchased items and track over time the cost of purchasing this basket. (Housing expenses, including rent and mortgages, constitute the largest component of the consumer basket in the United States.) The cost of this basket at a given time expressed relative to a base year is... (For example, if the base year CPI is 100 and the current CPI is 110, inflation is 10 percent over the period.) Core consumer inflation focuses on the underlying and persistent trends in inflation by excluding prices set by the government and the more volatile prices of products, such as food and energy, most affected by... Core inflation is also watched closely by policymakers. Calculation of an overall inflation rate—for a country, say, and not just for consumers—requires an index with broader coverage, such as the GDP deflator.

Core inflation is also watched closely by policymakers. Calculation of an overall inflation rate—for a country, say, and not just for consumers—requires an index with broader coverage, such as the GDP deflator. The CPI basket is mostly kept constant over time for consistency, but is tweaked occasionally to reflect changing consumption patterns—for example, to include new hi-tech goods and to replace items no longer widely purchased. Because it shows how, on average, prices change over time for everything produced in an economy, the contents of the GDP deflator vary each year and are more current than the mostly fixed CPI... On the other hand, the deflator includes nonconsumer items (such as military spending) and is therefore not a good measure of the cost of living. The good and the bad

IT may be one of the most familiar words in economics. Inflation has plunged countries into long periods of instability.

Core inflation is also watched closely by policymakers. Calculation of an overall inflation rate—for a country, say, and not just for consumers—requires an index with broader coverage, such as the gross domestic product (GDP) deflator. Recent price swings reflected largely energy- and supply-related shocks rather than macroeconomic overheating

As inflation began to rise in 2021, most policymakers and analysts predicted that the increase would be neither particularly large nor persistent. But by 2022, inflation had become an acute problem for central bankers. Then, after some of the sharpest and most synchronized monetary policy tightening on record, world inflation ebbed almost as suddenly as it had risen. We see two broad explanations. The first stresses that inflation rose at the same time in most countries because they were subjected—to varying degrees—to a similar sequence of shocks: the pandemic, mobility restrictions, and associated economic policy measures, especially... This emphasizes domestic drivers.

More fiscal and monetary support, tighter labor markets, or less-well-anchored inflation expectations would translate into higher inflation. The second stresses that inflation rose everywhere at the same time, not because local shocks were identical across countries, but because global causes were at play. The surge in energy and food prices, intensified by Russia’s invasion of Ukraine, triggered an energy crisis akin to the 1970s oil shocks. Geopolitics was the cause of both series of events. And it’s true that global energy prices and headline inflation rose together even as long-term inflation expectations held steady (see Chart 1). Our recent research (Dao and others, forthcoming) covering 21 advanced and emerging market economies sheds light on these competing explanations by decomposing headline consumer price inflation into underlying (core) inflation and headline shocks—deviations of...

We explain core inflation by long-term inflation expectations and broad measures of macroeconomic slack, such as the unemployment rate, the output gap, or the ratio of vacancies to unemployment. We explain headline inflation shocks by large price changes in particular industries, such as food, energy, or shipping, and by measures of supply-chain disruptions. We also allow for the pass-through over time from these industry price shocks to core inflation, which can occur through the effects of headline inflation on wages and other production costs.
