Explaining why they happen, and why so many businesses can fail at once, has been a major focus of economic theory and research, with several competing explanations. Financial, psychological, and real economic factors are at play in the causes and effects of recessions. Causes of the incipient recession in included the impact of COVID and the preceding decade of extreme monetary stimulus that left the economy vulnerable to economic shocks.

Interest Rates Interest rates are a key linkage between the purely financial sector and the real economic preferences and decisions of businesses and consumers.

Throughout the 19th and early 20th centuries, recessions were quite common. Between and , there were only 10 recession cycles, which is far fewer than we had seen in similar periods of time in the past.

Some economists use this as evidence that the business cycle has become less volatile. Although they're more or less a regular occurrence, and indicative of a cyclical business cycle, the duration, economic impact, and triggers of recessions can vary greatly. There are many indicators experts use to predict when a recession may occur, and the most reliable is an inverted yield curve.

Typically, interest rates for short-term loans are lower than rates of long-term loans. That's partly because a short-term loan is seen as a riskier investment for the lenders and partly because inflation is built into the interest rates. When this model is inverted, it can be a sign of a worsening economy, because it shows that there is less confidence in the long-term than there is in the short-term.

An inverted yield curve worries the market because it means "an expectation of low inflation, which comes with economic downturns" says Laura Ullrich , regional economist with the Federal Reserve Bank of Richmond, adding that inverted yield curves signal that people are "searching for safer places to put their money.

Since , an inverted yield curve has predicted each recession, and it should be noted that the curve did invert in Ullrich warns that there were other economic forces abroad that caused the most recent inversion. An economic depression is typically understood as an extreme downturn in economic activity lasting several years, but the exact definition and specifications of a depression are less clear.

The NBER notes that economists differ on the period of time that designates a depression. Some experts believe a depression lasts only when economic activity is declining, while the more common understanding is a depression extends until economic activity has returned to close to normal levels.

Recessions and depressions have similar indicators and causes, but the biggest differences are severity, duration, and overall impact. A depression spans years, rather than months, and typically sees higher unemployment and a sharper decline in GDP. And while a recession is often limited to a single country, a depression is usually severe enough to have global trade impacts.

Because economists do not have a set definition for what constitutes a depression, the general public sometimes uses it interchangeably with the term recession. But in the U. The Great Depression was one of the most severe economic downturns in history lasting from It started in America in as a recession before expanding globally, most notably in Europe. As with any long-term economic crisis, there wasn't just one event that led to the Great Depression, but rather a series of events including the stock market crash of and the severe drought of the Dust Bowl in the s.

As Mankiw pointed out, perhaps the most famous economic downturn in the U. Using the NBER business cycle dates, the first downturn of the Great Depression started in August and lasted 43 months, until March , far longer than any other twentieth century contraction.

The economy then expanded for 21 months, from March until May , before suffering another downturn: from May until June , a period of 13 months, the economy again contracted. One quick way to illustrate the difference between the severities of the economic contractions associated with recessions over the period from to is to examine the annual growth rates of real GDP in chained year dollars. Chart 1 shows the annual growth or contraction in the economy.

The gray bars represent recessions identified by the NBER. The two most severe contractions in output excluding the post-World War II adjustment from to occurred during the Great Depression of the s. The differences are telling:. During the major contraction phase of the Depression, between and , real output in the United States fell nearly 30 percent. During the same period, according to retrospective studies, the unemployment rate rose from about 3 percent to nearly 25 percent, and many of those lucky enough to have a job were able to work only part-time.

For comparison, between and , in what was perhaps the most severe U. Other features of the decline included a sharp deflation—prices fell at a rate of nearly 10 percent per year during the early s—as well as a plummeting stock market, widespread bank failures, and a rash of defaults and bankruptcies by businesses and households. The economy improved after Franklin D. Roosevelt's inauguration in March , but unemployment remained in the double digits for the rest of the decade, full recovery arriving only with the advent of World War II.

Moreover, as I will discuss later, the Depression was international in scope, affecting most countries around the world not only the United States. While you can see from the above discussion that recessions and depressions are serious business, some economists have been known to suggest that there is another more casual way to explain the difference between a recession and a depression recall that I began this answer with a promise of a joke :.
