Consumer Spending and Its Impact on the Economy
What You Buy Every Day Drives U.S. Economic Growth
Consumer spending is what households buy to fulfill everyday needs. This private consumption includes both goods and services. Every one of us is a consumer. The things we buy every day create the demand that keeps companies profitable and hiring new workers.
Cable and internet services also count, and even services from non-profits.
The remaining one-third of our personal consumption expenditure is on goods. These include so-called durable goods, such as washing machines, automobiles, and furniture. More frequently, we buy non-durable goods, such gasoline, groceries, and clothing.
Five Determinants of Consumer Spending
There are five determinants of consumer spending. These are the things that affect how much you spend. Changes in any of these components will affect consumer spending.
The most important determinant is disposable income. That's the average income minus taxes. Without it, no one would have the funds to buy the things they need. That makes disposable income one of the most important determinants of demand. As income increases so does demand. If manufacturers ramp up to meet demand, they create jobs. Workers' wages rise, creating more spending.
It's a virtuous cycle leading to ongoing economic expansion. If demand increases but manufacturers don't increase supply, then they will raise prices. That creates inflation.
The second component is income per capita. It tells you how much each person has to spend. Income measurements might rise just because the population increases.
Income per person reveals whether each person's standard of living is also improving.
Income inequality is the third determinant of spending. Some people's income may rise at a faster pace than others. The economy benefits when most of the gain goes toward low-income families. They must spend a more significant share of each dollar on necessities until they reach a living wage. The economy doesn't benefit as much when increases go toward high-income earners. They are more likely to save or invest additions to income instead of spending.
The fourth factor is the level of household debt. That includes credit card debt, auto loans, and school loans. Current consumer debt statistics show that household debt has reached new record levels. Surprisingly, high health care costs are one of the biggest causes of overwhelming debt.
The fifth determinant is consumer expectations. If people are confident, they are more likely to spend now. The Consumer Confidence Index measures how confident people are about the future. It includes their expectations of inflation. If consumers expect inflation to be high, they will buy more now to avoid future price increases. That's why the Federal Reserve targets a 2 percent inflation rate.
Why It's Important
Consumer spending is the single most important driving force of the U.S. economy. Keynesian economic theory says that the government should stimulate spending to end a recession. Supply-side economists recommend the opposite. They believe the government should cut business taxes to create jobs. But companies won't increase production if the demand is not there.
If you doubt this, think about what would happen if everyone stopped spending. Businesses would eventually go bankrupt and lay off workers. The government would then have no one to tax.
The economy would have to rely on exports, assuming other countries kept up their consumer spending. Borrowing would keep the government and factories open. These additional components of gross domestic product aren't as critical as consumer spending.
Even a small downturn in consumer spending can damage the economy. As it drops off, economic growth slows. Prices will drop, which creates deflation. If slow consumer spending continues, the economy can go into recession.
But too much of a good thing can be damaging. When consumer demand exceeds manufacturers' ability to provide the goods and services, prices increase. If this goes on, it creates inflation. If consumers expect ever-increasing prices, they will spend more now. That further increases demand, forcing business to hike their prices. It becomes a self-fulfilling prophecy that is very difficult to stop. That's why the primary mandate of the nation's central bank, the Federal Reserve, is to ward off inflation.
How Consumer Spending Is Measured
Consumer spending is measured in many different ways. The most comprehensive is the monthly Personal Consumption Expenditures report.
The Consumer Expenditure Survey is released in August each year by the Bureau of Labor Statistics. It is similar to the PCE but has a little more detail about types of households. That's because the BLS analyzes data from the U.S. Census. The BLS releases its report in September each year. Here's the most current report.
