How To Calculate The Economic Growth Rate
How To Calculate The Economic Growth Rate – 3 C H A P T E R C H E C L I S O After studying this chapter, you will be able to 1 define and calculate the rate of economic growth and explain the consequences of sustainable growth. 2 Identify the main sources of economic growth. 3 Consider theories of economic growth and why growth rates vary over time and across countries. 4 Describe policies that can boost economic growth.
Economic growth is the steady expansion of productive capacity as measured by the increase in real gross output over a period of time. Calculating the Growth Rate The economic growth rate is the rate of change in real gross product expressed as a percentage per year.
How To Calculate The Economic Growth Rate
To calculate this growth rate, we use the formula: Real GDP Growth = Real GDP in the current year Real GDP in the previous year x 100 – For example, if real GDP in the current year is $8.4 trillion and real GDP in the previous year is . 8.0 trillion.

Standard of living depends on real gross product per person. Real GDP per capita is real GDP divided by population. The contribution of real GDP growth to changes in living standards depends on the rate of real GDP growth per person.
To calculate this growth rate, we use the formula above, substituting real GDP per capita with real GDP. For example, in the current year, the population is 202 million, with a GDP of 8.4 trillion dollars. Then the GDP per capita of $8.4 trillion divided by 202 million equals $41,584. Last year, the population was 200 million, with a GDP of $8.0 trillion. Then GDP per capita that year was 8,000 billion USD divided by 200 million USD, which equals 40,000,000 USD.
Use these two values of real GDP per capita in the growth formula to calculate the growth rate of real GDP per capita. This is a growth rate of real gross product per capita of $41,584 – $40,000 $40,000 x 100 = 4 percent. =

The growth rate of real GDP per capita can also be calculated using the formula: Real GDP growth per capita Real GDP growth rate Population growth rate – = Population 202 million – 200 million 200 million x 100 = 1 percent. =
Growth in real GDP per capita is 5 percent – 1 percent = 4 percent. = This formula states that GDP per capita is growing faster than population growth. If the rate of population growth exceeds real GDP growth, GDP per capita falls.
The Magic of Sustainable Growth Sustainable growth in real GDP per capita can transform a poor society into a rich one. The reason is that economic development seems to be a complex interest. The rule of 70 is the number of years it takes to double the level of any variable divided by the annual percentage growth rate of the variable, which is approximately 70.

To understand what determines the growth rate of real GDP, we must understand what determines the growth rate of the factors of production and the rate of increase in their productivity. All effects on real GDP growth can be broken down into those that increase total hourly productivity
Total hours Total hours increase over time. This increase in total hours comes from an increase in the labor force, not from an increase in average hours per worker. Although participation rates have increased over the past few decades, there is an upper limit, and most of the total hours are due to population growth. Population growth is therefore a source of growth in total working hours that can be sustained over a long period of time.

Population growth leads to economic growth, but it does not lead to per capita GDP growth unless labor becomes more efficient. Labor productivity Labor productivity is the actual gross output produced by one hour of work. It is calculated using the formula: Real GDP Labor Productivity = Total Hours
For example, if real gross product is $8,000,000 and total hours are $200 billion, we can calculate labor productivity as $200 billion Labor productivity = $8,000,000 billion = $40 per hour You can reverse this formula to see real GDP. = Total hours x Labor productivity
When labor productivity increases, GDP per capita increases, so the increase in labor productivity is the basis for raising the standard of living. The growth of labor productivity depends on three things: preservation and investment of physical capital, expansion of human capital, discovery of new technologies.
Economic Growth And Recession Predictions
Savings and investments in physical capital Savings and investments in physical capital increase the amount of capital per worker and increase labor productivity. Increasing Human Capital Human capital – the accumulated skills and knowledge of people – comes from two sources: Education and training Work experience
Discovery of new technologies The capital must increase to take advantage of the technological change. Some of the most powerful and far-reaching technologies have been embodied in human capital. For example, language, writing, mathematics. But most technologies are embodied in physical capital.
Sources of Growth: Summary Figure 9.1 shows the sources of economic growth. Real GDP growth depends on total growth in hours worked and growth in labor productivity.

Classical growth theory Classical growth theory is the theory that the conflict between an exploding population and limited resources will eventually end economic growth. Malthusian theory is another name for the classical theory of development – for Thomas Robert Malthus.
Basic ideas and capital accumulation in technology increase productivity and increase real gross product per person. According to classical growth theory, increases in GDP per capita will be temporary because prosperity will lead to a population boom. A population boom will reduce real GDP per person.
Classical Theory of Population Growth When classical economists developed their ideas about population growth, an unprecedented population explosion occurred. To explain the high rate of population growth, classical economists used the real idea of living (real GDP per capita). In classical theory, population increases when real income exceeds subsistence.

Population growth reduces the amount of capital employed per hour, so labor productivity and real GDP per capita decrease. So no matter how much technological change occurs, real income (gross GDP per capita) is always pushed back to the standard of living. This unfortunate result has led to economics being called “bad science.”
As shown in Figure 9.2, population increases when wages are higher than the living wage. 1. Labor supply increases. 2. Wages are falling. 3. Employment is increasing.
Population and labor supply increase until the wage rate equals the subsistence level.

4. Increase in employment… 5. Increases real GDP. Population growth increases employment and real GDP, and decreases the hourly wage rate and real GDP.
Real gross output per hour of labor decreases. Diminishing returns are the tendency for each additional hour of labor to produce a successively smaller additional amount. Thus, if the real wage rate under classic labor exceeds the subsistence minimum, population growth causes wages to fall and real gross product per hour of labor to decrease.
Neoclassical Growth Theory Neoclassical Growth Theory is the theory that human real GDP will increase until technology advances. Neoclassical growth theory predicts that real GDP growth rates will be equal to population growth rate and labor productivity growth. Real GDP per capita will increase as technology advances – economic growth will continue.
Sustainable Growth Rate (sgr)
Population Growth Two opposing economic forces affect population growth. As incomes rise, the birth rate falls and the death rate falls. These opposing forces are offset, so the rate of population growth is independent of the rate of economic growth. Historical population trends contradict the views of classical economists.
Technological Change In neoclassical theory, the rate of technological change affects the rate of economic growth, but economic growth does not affect the rate of technological change. Technological change happens by accident. Fortunately, we are experiencing rapid technological change. With bad luck, the pace of technological progress slows down
The basic idea is that technological advances bring profit opportunities. Businesses are expanding and new businesses are being created to take advantage of new technologies. Investment and saving increase, so capital per hour of labor increases. The economy is enjoying prosperity and growth.

But will the abundance last? Will the growth continue? Neoclassical growth theory says that prosperity will continue, but if technology does not advance, there will be no growth.
