GDP (Gross Domestic Product) helps to measure the economic performance of any country. It is the monetary value of all the goods and services produced within the country’s border over a specific time, usually in a year.


The components of GDP are

  1. Consumption
  2. Investments
  3. Government spending
  4. Net Exports

Consumption is private spending on goods and services.

Investment is acquiring capital, or plant and equipment, for business use.

Government spending includes federal and state government spending and transfer payments from programs such as Social Security.

Net exports are exports minus imports.

GDP is a key factor for economic health because it’s an overall measure of economic activity. When it is increases steadily, it signals that the economy is growing healthy. When decreases, it indicates that the economy is contracting and in recession.

GDP compares the performance of a country

It is also used to compare the performance of different countries over time or to compare economies of different sizes.

  • For example, comparing a large country like the United States to a smaller country like Belgium is easier when their respective GDP figures are compared. Since GDP is expressed in currency, it’s also possible to compare countries even if they don’t use the same currency.


10 Surprising Factors That Affect GDP

Here are ten factors that can affect GDP

1. Consumer spending affects


Consumer spending is one of the main factors in determining the health of an economy. Consumers’ spending fuels economic growth as businesses create more jobs and invest in production to meet demand.

In addition, Consumer spending is, naturally, essential to businesses. The more money consumers spend at a given company, the better that company tends to perform. For this reason, it is unsurprising that most investors and businesses pay a significant amount of attention to consumer spending figures and patterns. Investors and businesses closely follow consumer spending statistics when making forecasts.

2. Interest rates


Interest rates can have a significant effect on an economy. Lower interest rates encourage borrowing and spending, driving economic growth. Higher interest rates make it more expensive for businesses and individuals to borrow money, slowing economic growth.

How does an increase in interest rates affect real GDP?

An increase in interest rates increases the incentive to save, as the reward for saving is now higher. So, saving in the economy will likely increase, decreasing consumption (assuming that people’s incomes stay the same). An increase in interest rates increases the cost of borrowing and, therefore, the cost of investing. This discourages businesses from investing and, as a result, investment in the economy decreases.

The government debt interest payments will rise due to the higher cost of borrowing – but we cannot predict the effect this will have on government spending. So, we will ignore it for this question.

3. Government spending

Governments are often responsible for large-scale investments and spending programs. These programs can affect both short-term and long-term growth, depending on the types of programs implemented.

The increased government spending may create a multiplier effect. If government spending causes the unemployed to gain jobs, they will have more income to spend, leading to a further increase in aggregate demand. In these situations of spare capacity in the economy, government spending may cause a bigger final increase in GDP than the initial injection.

4. Foreign trade

A country’s GDP is also affected by how much it trades with other countries. When a country exports more than it imports, the difference is added to the GDP. Similarly, the difference is deducted from GDP when it imports more than it exports.

The balance of trade is one of the key elements of a country’s gross domestic product (GDP) formula. GDP increases when there is a trade surplus: the total value of goods and services that domestic producers sell abroad exceeds the total value of foreign goods and services that domestic consumers buy.

5. Tax policies

Government tax policies can have a big impact on GDP. Lower taxes can encourage businesses to hire more workers and invest in production, while higher taxes can have the opposite effect.

6. Technological advancement

Technological advancement can fuel economic growth. New technologies can increase productivity and create new markets, creating jobs and higher Gross Domestic Product.

7. Employment rate

The unemployment rate is a key measure of economic health. High unemployment tends to lead to slower economic growth and lower GDP, while low unemployment indicates a healthy economy.

8. Inflation


Inflation can have both negative and positive effects on GDP. Too much inflation can erode savings and purchasing power, but ordinary inflation is usually necessary for economic growth.

The Relationship Between Inflation and GDP

However, too much GDP growth is also dangerous, as it will most likely come with an increase in inflation, which erodes stock market gains by making our money (and future corporate profits) less valuable.

9. Natural resources

Natural resources such as oil, gas, etc., can be a significant source of income for countries with rich supplies. The sale of these resources can come up with notable to GDP.

10. Population growth

Population growth can affect GDP. A growing population means larger workers and increased consumption, which can lead to economic growth. On the other hand, an aging population can cause a reduction in the number of workers and consumers, limiting economic growth.

For example, an increase in the number of people in the United States will lead to more access to labor, which will lead to higher productivity and more goods being produced. Output (as measured by GDP) will increase in the country as a result!
