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 are the four variables that contribute to GDP growth?
Natural resources, capital goods, human resources, and technology are the four supply variables that have a direct impact on the value of goods and services delivered. Economic growth, as measured by GDP, refers to an increase in the rate of growth of GDP, but what affects the rate of growth of each component is quite different.
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.
What factors can boost real GDP?
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 are GDP’s five components?
(Private) consumption, fixed investment, change in inventories, government purchases (i.e. government consumption), and net exports are the five primary components of GDP. The average growth rate of the US economy has traditionally been between 2.5 and 3.0 percent.
What is meant by the word “investment?
What exactly do economists mean when they talk about investment or company spending? The purchase of stocks and bonds, as well as the trading of financial assets, are not included in the calculation of GDP. It refers to the purchase of new capital goods, such as commercial real estate (such as buildings, factories, and stores), equipment, and inventory. Even if they have not yet sold, inventories produced this year are included in this year’s GDP. It’s like if the company invested in its own inventories, according to the accountant. According to the Bureau of Economic Analysis, business investment totaled more than $2 trillion in 2012.
In 2012, Table 5.1 shows how these four components contributed to the GDP. Figure 5.4 (a) depicts the percentages of GDP spent on consumption, investment, and government purchases across time, whereas Figure 5.4 (b) depicts the percentages of GDP spent on exports and imports over time. There are a few trends worth noting concerning each of these components. The components of GDP from the demand side are shown in Table 5.1. The percentages are depicted in Figure 5.3.
Key Points
- Consumer spending, government spending, investment, and net exports all contribute to aggregate demand (AD).
- A drop in the money supply is accompanied by a corresponding decrease in nominal output, also known as GDP ( GDP ).
- Consumer spending will be affected by the reduction in the money supply. The AD curve will move to the left as a result of this decline.
- An rise in the money supply is accompanied by an equal increase in nominal output, or GDP (GDP).
- The expansion of the money supply will result in more consumer expenditure. The AD curve will move to the right as a result of this increase.
- Increased money supply leads to lower interest rates and more spending, resulting in an increase in AD.
What happens if the GDP rises?
More employment are likely to be created as GDP rises, and workers are more likely to receive higher wage raises. When GDP falls, the economy shrinks, which is terrible news for businesses and people.
