Striving for Economic Growth

Perhaps the most important way to judge a nation’s economic health is to look at its production of goods and services. The more the nation produces, the higher its standard of living. An increase in a nation’s output of goods and services is economic growth.

The most basic measure of economic growth is the gross domestic product (GDP). GDP is the total market value of all final goods and services produced within a nation’s borders each year. The Bureau of Labor Statistics publishes quarterly GDP figures that can be used to compare trends in national output. When GDP rises, the economy is growing.

The rate of growth in real GDP (GDP adjusted for inflation) is also important. Recently, the U.S. economy has been growing at a slow but steady rate of between 3 and 4 percent annually. This growth rate has meant a steady increase in the output of goods and services and relatively low unemployment. When the growth rate slides toward zero, the economy begins to stagnate and decline.

One country that continues to grow more rapidly than most is China, whose GDP has been growing at 6 to 7 percent per year. Today few things in the global marketplace are not or cannot be made in China. The primary contributor to China’s rapid growth has been technology. For example, most tablets and laptops are manufactured in China.

The level of economic activity is constantly changing. These upward and downward changes are called business cycles. Business cycles vary in length, in how high or low the economy moves, and in how much the economy is affected. Changes in GDP trace the patterns as economic activity expands and contracts. An increase in business activity results in rising output, income, employment, and prices. Eventually, these all peak, and output, income, and employment decline. A decline in GDP that lasts for two consecutive quarters (each a three-month period) is called a recession. It is followed by a recovery period when economic activity once again increases. The most recent recession began in December 2007 and ended in June 2009.

Businesses must monitor and react to the changing phases of business cycles. When the economy is growing, companies often have a difficult time hiring good employees and finding scarce supplies and raw materials. When a recession hits, many firms find they have more capacity than the demand for their goods and services requires. During the most recent recession, many businesses operated at substantially lower than capacity. When plants use only part of their capacity, they operate inefficiently and have higher costs per unit produced. Let’s say that Mars Corp. has a huge plant that can produce one million Milky Way candy bars a day, but because of a recession Mars can sell only half a million candy bars a day. The plant uses large, expensive machines. Producing Milky Ways at 50 percent capacity does not efficiently utilize Mars’s investment in its plant and equipment.

Keeping People on the Job

Another macroeconomic goal is full employment, or having jobs for all who want to and can work. Full employment doesn’t actually mean 100 percent employment. Some people choose not to work for personal reasons (attending school, raising children) or are temporarily unemployed while they wait to start a new job. Thus, the government defines full employment as the situation when about 94 to 96 percent of those available to work actually have jobs. During the 2007–2009 recession in the United States, the unemployment rate peaked at 10 percent in October 2009. Today, that rate hovers at about 4 percent.^[1]

Maintaining low unemployment levels is of concern not just to the United States but also to countries around the world. For example, high youth unemployment rates (for workers 25 years of age and younger) in Spain, Italy, and Greece continue to cause protests in these European countries as elected officials struggle with how to turn around their respective economies and put more people, particularly young people, back to work. The UK’s impending exit from the European Union may also have an effect on unemployment rates, as global companies move jobs out of Britain to central European countries such as Poland.^[2]

To determine how close we are to full employment, the government measures the unemployment rate. This rate indicates the percentage of the total labor force that is not working but is actively looking for work. It excludes “discouraged workers,” those not seeking jobs because they think no one will hire them. Each month the U.S. Department of Labor releases statistics on employment. These figures help us understand how well the economy is doing.

Types of Unemployment

Economists classify unemployment into four types: frictional, structural, cyclical, and seasonal. The categories are of small consolation to someone who is unemployed, but they help economists understand the problem of unemployment in our economy.

Frictional unemployment is short-term unemployment that is not related to the business cycle. It includes people who are unemployed while waiting to start a better job, those who are reentering the job market, and those entering for the first time, such as new college graduates. This type of unemployment is always present and has little impact on the economy.

Structural unemployment is also unrelated to the business cycle but is involuntary. It is caused by a mismatch between available jobs and the skills of available workers in an industry or a region. For example, if the birthrate declines, fewer teachers will be needed. Or the available workers in an area may lack the skills that employers want. Retraining and skill-building programs are often required to reduce structural unemployment.

Cyclical unemployment, as the name implies, occurs when a downturn in the business cycle reduces the demand for labor throughout the economy. In a long recession, cyclical unemployment is widespread, and even people with good job skills can’t find jobs. The government can partly counteract cyclical unemployment with programs that boost the economy.

In the past, cyclical unemployment affected mainly less-skilled workers and those in heavy manufacturing. Typically, they would be rehired when economic growth increased. Since the 1990s, however, competition has forced many American companies to downsize so they can survive in the global marketplace. These job reductions affected workers in all categories, including middle management and other salaried positions. Firms continue to reevaluate workforce requirements and downsize to stay competitive to compete with Asian, European, and other U.S. firms. After a strong rebound from the global recession of 2007–2009, when the auto industry slashed more than 200,000 hourly and salaried workers from their payrolls, the automakers are now taking another close look at the size of their global workforces. For example, as sales steadily rose after the recession, Ford Motor Company’s workforce in North America increased by 25 percent over the past five years. As car sales plateaued in 2017, the company recently announced it would cut approximately 10 percent of its global workforce in an effort to reduce costs, boost profits, and increase its stock value for shareholders.^[3]

The last type is seasonal unemployment, which occurs during specific times of the year in certain industries. Employees subject to seasonal unemployment include retail workers hired for the holiday shopping season, lettuce pickers in California, and restaurant employees in ski country during the summer.

Keeping Prices Steady

The third macroeconomic goal is to keep overall prices for goods and services fairly steady. The situation in which the average of all prices of goods and services is rising is called inflation. Inflation’s higher prices reduce purchasing power, the value of what money can buy. Purchasing power is a function of two things: inflation and income. If incomes rise at the same rate as inflation, there is no change in purchasing power. If prices go up but income doesn’t rise or rises at a slower rate, a given amount of income buys less, and purchasing power falls. For example, if the price of a basket of groceries rises from $30 to $40 but your salary remains the same, you can buy only 75 percent as many groceries ($30 ÷ $40) for $30. Your purchasing power declines by 25 percent ($10 ÷ $40). If incomes rise at a rate faster than inflation, then purchasing power increases. So you can, in fact, have rising purchasing power even if inflation is increasing. Typically, however, inflation rises faster than incomes, leading to a decrease in purchasing power.

Inflation affects both personal and business decisions. When prices are rising, people tend to spend more—before their purchasing power declines further. Businesses that expect inflation often increase their supplies, and people often speed up planned purchases of cars and major appliances.

From the early 2000s to April 2017, inflation in the United States was very low, in the 0.1 to 3.8 percent range; for 2016 it was 1.3 percent. For comparison, in the 1980s, the United States had periods of inflation in the 12 to 13 percent range.^[4] Some nations have had high double- and even triple-digit inflation in recent years. As of early 2017, the monthly inflation rate in Venezuela was an astounding 741 percent, followed by the African country of South Sudan at 273 percent.^[5]
