Gross Domestic Product (GDP) is a widely used measure of economic activity that is typically used to describe the size and growth of an economy. It is often considered one of the most important economic indicators because it provides a snapshot of a country’s overall economic health. GDP can be used in many ways on an international level to assess economic development, compare living standards, and evaluate policy effectiveness. In this essay, we will discuss the use of GDP on an international level in detail.
The Basics of GDP
Gross Domestic Product (GDP) is the total value of all goods and services produced within a country’s borders over a specific period, usually a year. It measures the final value of all goods and services produced in a country and includes the value added by all sectors of the economy. GDP is typically used as an indicator of the size and growth of a country’s economy. GDP can be calculated in three ways: the expenditure approach, the income approach, and the production approach.
Let’s understand more about GDP with the help of graph:

The Expenditure Approach: GDP can be calculated by adding up all the expenditures on final goods and services produced in a country. This includes consumption by households, government spending, investment by businesses, and net exports (exports minus imports).
The Income Approach: GDP can also be calculated by adding up all the income earned by individuals and businesses in a country. This includes wages and salaries, profits, rent, and interest.
The Production Approach: GDP can also be calculated by adding up the value added by all sectors of the economy. This approach measures the value of all goods and services produced in a country, minus the value of intermediate goods and services used in the production process.
The Use of GDP on an International Level
There are several ways in which GDP is used on an international level to assess economic development, compare living standards, and evaluate policy effectiveness. These uses are discussed in detail below:

Economic Development: GDP is often used as a measure of economic development. Higher GDP levels are generally associated with greater economic development and improved living standards. Countries with higher GDP per capita tend to have higher levels of human development, including better health, education, and access to basic services. However, it is important to note that GDP per capita alone does not capture the full picture of economic development. Other factors such as income inequality, environmental sustainability, and social development must also be taken into account.
International Comparisons: GDP is also used to compare living standards between countries. GDP per capita is often used as a measure of a country’s standard of living, although it has limitations. For example, it does not take into account income inequality or the distribution of income and wealth within a country. Nonetheless, GDP per capita can be a useful tool for comparing the economic well-being of different countries.
Policy Effectiveness: GDP is used to evaluate the effectiveness of economic policies. For example, if a country implements a policy to stimulate economic growth, GDP can be used to measure the impact of the policy. If GDP increases, it can be inferred that the policy was successful. Similarly, if GDP decreases, it can be inferred that the policy was not successful.
Investment Decisions: GDP is used to inform investment decisions. Investors often use GDP growth rates as an indicator of a country’s economic potential. If a country’s GDP is growing rapidly, it is seen as a good place to invest. However, it is important to note that high GDP growth rates do not always translate into high returns on investment.
International Trade: GDP is also used to inform international trade decisions. Countries with higher levels of GDP tend to be more attractive to trade partners.GDP is an important measure in international trade as it reflects a country’s economic activity and potential purchasing power. A country with a high GDP is generally seen as more attractive to trade partners due to its larger market for goods and services, greater purchasing power, and more developed infrastructure. GDP can also be used to assess the impact of international trade on a country’s economy. Increased exports can lead to higher GDP growth, while imports can have a negative impact on GDP if they exceed exports.
