The value of economic output adjusted for price fluctuations is measured by real gross domestic product (real GDP) (i.e. inflation or deflation). This adjustment converts nominal GDP, a money-value metric, into a quantity-of-total-output index. Although GDP stands for gross domestic product, it is most useful since it roughly approximates total spending: the sum of consumer spending, industrial investment, the surplus of exports over imports, and government spending. GDP rises as a result of inflation, yet it does not accurately reflect an economy’s true growth. To calculate real GDP growth, the GDP must be divided by the inflation rate (raised to the power of the units of time in which the rate is measured). The UNCTAD uses 2005 constant prices and exchange rates, while the FRED uses 2009 constant prices and exchange rates, while the World Bank just shifted from 2005 to 2010 constant prices and currency rates.
What factors would cause real GDP to rise?
A rise in aggregate demand drives economic growth in the short run (AD). If the economy has spare capacity, an increase in AD will result in a higher level of real GDP.
Factors which affect AD
- Lower interest rates – Lower interest rates lower borrowing costs, which encourages consumers to spend and businesses to invest. Lower interest rates cut mortgage payments, increasing consumers’ discretionary income.
- Wages have been raised. Increased real wages enhance disposable income, which encourages consumers to spend.
- Greater government expenditure (G), such as government investments in new roads or increased spending on welfare payments, both of which enhance disposable income.
- Devaluation. A decrease in the value of the currency rate (for example, the Pound Sterling) lowers the cost of exports and increases the volume of exports (X). Imports become more expensive as a result of depreciation, lowering the quantity of imports and making domestic goods more appealing.
- Confidence. Households with higher consumer confidence are more likely to spend, either by depleting their savings or taking out more personal credit. It encourages spending by allowing increased spending (C) (C).
- Reduced taxation. Consumers’ disposable income will increase as a result of lower income taxes, which will lead to increased expenditure (C).
- House prices are increasing. A rise in housing prices results in a positive wealth effect. Homeowners who see their property value rise will be more willing to spend (remortgaging house if necessary)
- Financial stability is important. Firms will be more eager to invest if there is financial stability and banks are willing to lend, and investment will enhance aggregate demand.
Long-term economic growth
This necessitates an increase in both AD and long-run aggregate supply (productive capacity).
- Capital increase. Investment in new manufacturing or infrastructure, such as roads and telephones, are examples.
- Increased labor productivity as a result of improved education and training, as well as enhanced technology.
- New raw materials are being discovered. Finding oil reserves, for example, will boost national output.
- Microcomputers and the internet, for example, have both led to higher economic growth through improving capital and labor productivity. New technology, such as artificial intelligence (AI), which allows robots to take the place of human workers, may be the source of future economic growth.
Other factors affecting economic growth
- Stability in the economy and politics. Stability is vital for convincing businesses that investing in capacity expansion is a sensible decision. When there is a surge in uncertainty, confidence tends to diminish, which can cause businesses to postpone investment.
- Inflation is low. Low inflation creates a favorable environment for business investment. Volatility is exacerbated by high inflation.
Periods of economic growth in UK
The United Kingdom saw substantial economic expansion in the 1980s, owing to a number of factors.
- Reduced income taxes increase disposable income, which leads to increased expenditure and, in turn, stimulates corporate investment.
- House prices rose, resulting in a positive wealth effect, equity withdrawal, and increased consumer spending.
What causes real GDP to rise or fall?
Customer Spending Trends Any decline in customer spending will result in a drop in GDP. Customers spend more or less depending on their disposable income, inflation, tax rate, and debt load. Wage growth, for example, stimulates consumers to make more expensive purchases, resulting in a rise in real GDP.
What factors influence real GDP?
Adjustments for changes in inflation are factored into real GDP. This means that when inflation is high, real GDP is lower than nominal GDP, and vice versa. Positive inflation, without a real GDP adjustment, dramatically inflates nominal GDP.
What factors boost GDP?
The external balance of trade is the most essential of all the components that make up a country’s GDP. When the total value of products and services sold by local producers to foreign countries surpasses the total value of foreign goods and services purchased by domestic consumers, a country’s GDP rises. A country is said to have a trade surplus when this happens.
What happens to real income when real GDP rises?
Finally, evaluate the consequences of a rise in real gross domestic product (GDP) (GDP). Such an increase indicates that the economy is growing. As a result, looking at the implications of a rise in real GDP is the same as looking at how interest rates will change as a result of economic expansion.
GDP may rise for a variety of causes, which will be examined in more detail in the next chapters. For the time being, we’ll assume that GDP rises for no apparent reason and explore the implications of such a development in the money market.
Assume the money market is initially in equilibrium with real money supply MS/P$ and interest rate i$ at point A in Figure 18.5 “Effects of an Increase in Real GDP.” Assume, for the sake of argument, that real GDP (Y$) rises. The ceteris paribus assumption states that all other exogenous variables in the model will remain constant at their initial values. It means that the money supply (MS) and the price level (P$) are both fixed in this exercise. People will need more money to make the transactions required to purchase the new GDP, hence a growth in GDP will enhance money demand. In other words, the transactions demand effect raises real money demand. The rightward change of the real money demand function from L(i$, Y$) to L(i$, Y$) reflects this rise.
What is the rate of growth of real GDP?
During the four phases of the business cycle: peak, contraction, trough, and expansion, the GDP growth rate changes. The GDP growth rate will be positive in an increasing economy because firms will expand and create jobs, resulting in increased productivity.
What happens to unemployment when real GDP rises?
Employment will rise as long as growth in real gross domestic product (GDP) outpaces growth in labor productivity. The unemployment rate will fall if employment growth outpaces labor force growth.
What happens if the real GDP falls?
When GDP falls, the economy shrinks, which is terrible news for businesses and people. A recession is defined as a drop in GDP for two quarters in a row, which can result in pay freezes and job losses.
Is real GDP inflation-adjusted?
The inflation-adjusted value of goods and services produced by labor and property in the United States is known as real gross domestic product.
How can you boost GDP growth?
- AD stands for aggregate demand (consumer spending, investment levels, government spending, exports-imports)
- AS stands for aggregate supply (Productive capacity, the efficiency of economy, labour productivity)
To increase economic growth
1. An increase in total demand
- Lower interest rates lower borrowing costs and boost consumer spending and investment.
- Increased real wages when nominal salaries rise faster than inflation, consumers have more money to spend.
- Depreciation reduces the cost of exports while raising the cost of imports, increasing domestic demand.
- Growing wealth, such as rising house values, encourages people to spend more (since they are more confident and can refinance their home).
This represents a rise in total supply (productive capacity). This can happen as a result of:
- In the nineteenth century, new technologies such as steam power and telegrams aided productivity. In the twenty-first century, the internet, artificial intelligence, and computers are all helping to boost productivity.
- Workers become more productive when new management approaches, such as better industrial relations, are introduced.
- Increased net migration, with a particular emphasis on workers with in-demand skills (e.g. builders, fruit pickers)
- Infrastructure improvements, greater education spending, and other public-sector investments are examples of public-sector investment.
To what extent can the government increase economic growth?
A government can use demand-side and supply-side policies to try to influence the rate of economic growth.
- Cutting taxes to raise disposable income and encourage spending is known as expansionary fiscal policy. Lower taxes, on the other hand, will increase the budget deficit and lead to more borrowing. When there is a drop in consumer expenditure, an expansionary fiscal policy is most appropriate.
- Cutting interest rates can promote domestic demand. Expansionary monetary policy (currently usually set by an independent Central Bank).
- Stability. The government’s primary job is to maintain economic and political stability, which allows for normal economic activity to occur. Uncertainty and political polarization can deter investment and growth.
- Infrastructure investment, such as new roads, railway lines, and broadband internet, boosts productivity and lowers traffic congestion.
Factors beyond the government’s influence
- It is difficult for the government to influence the rate of technical innovation because it tends to come from the private sector.
- The private sector is in charge of labor relations and employee motivation. At best, the government has a minimal impact on employee morale and motivation.
- Entrepreneurs are primarily self-motivated when it comes to starting a firm. Government restrictions and tax rates can have an impact on a business owner’s willingness to take risks.
- The amount of money saved has an impact on growth (e.g. see Harrod-Domar model) Higher savings enable higher investment, yet influencing savings might be difficult for the government.
- Willingness to put forth the effort. The vanquished countries of Germany and Japan had fast economic development in the postwar period, indicating a desire to rebuild after the war. The UK economy was less dynamic, which could be due to different views toward employment and a willingness to try new things.
- Any economy is influenced significantly by global growth. It is extremely difficult for a single economy to avoid the costs of a global recession. The credit crunch of 2009, for example, had a detrimental impact on economic development in OECD countries.
In 2009, the United States, France, and the United Kingdom all went into recession. The greater recovery in the United States, on the other hand, could be attributed to different governmental measures. 2009/10 fiscal policy was expansionary, and monetary policy was looser.
Governments frequently overestimate their ability to boost productivity growth. Without government intervention, the private sector drives the majority of technological advancement. Supply-side measures can help boost efficiency to some level, but how much they can boost growth rates is questionable.
For example, after the 1980s supply-side measures, the government looked for a supply-side miracle that would allow for a significantly quicker pace of economic growth. The Lawson boom of the 1980s, however, proved unsustainable, and the UK’s growth rate stayed relatively constant at roughly 2.5 percent. Supply-side initiatives, at the very least, will take a long time to implement; for example, improving labor productivity through education and training will take many years.
There is far more scope for the government to increase growth rates in developing economies with significant infrastructure failures and a lack of basic amenities.
The potential for higher growth rates is greatly increased by providing basic levels of education and infrastructure.
The private sector is responsible for the majority of productivity increases. With a few exceptions, private companies are responsible for the majority of technical advancements. The great majority of productivity gains in the UK is due to new technologies developed by the private sector. I doubt the government’s ability to invest in new technologies to enhance productivity growth at this rate. (Though it is possible especially in times of conflict)
Economic growth in the UK
The UK economy has risen at a rate of 2.5 percent each year on average since 1945. Most economists believe that the UK’s productive capacity can grow at a rate of roughly 2.5 percent per year on average. The underlying trend rate is also known as the ‘trend rate of growth.’
Even when the government pursued supply-side reforms, they were largely ineffective in changing the long-run trend rate. (For example, in the 1980s, supply-side policies had minimal effect on the long-run trend rate.)
The graph below demonstrates how, since 2008, actual GDP has fallen below the trend rate. Because of the recession and a considerable drop in aggregate demand, this happened.
- Improved private-sector technology that allows for increased labor productivity (e.g. development of computers enables greater productivity)
- Infrastructure investment, such as the construction of new roads and train lines. The government is mostly responsible for this.
