GDP (Gross Domestic Product)
GDP (Gross Domestic Product) refers to the total value of goods and services produced within a country over a certain period, such as a year. It reflects the state of economic activities within a nation.
By understanding GDP, we can gauge the overall profitability generated domestically and assess the economic condition of a country. This article provides an in-depth explanation of GDP, including the distinctions between nominal and real GDP, calculation methods, and the latest global GDP rankings.
Overview of GDP
GDP, or Gross Domestic Product, represents the total value added from goods and services produced within a country over a specific period. It serves as an indicator of the size of a country's economic activities.
Since it focuses on "domestic" production, it excludes value-added services or goods produced overseas.
Value-added refers to the amount remaining after deducting costs and transportation expenses from goods or services. In other words, it can also be described as the "total profits" generated domestically. GDP is mainly used to measure the economic climate and is often expressed as a percentage increase or decrease compared to the previous year to illustrate economic trends.
GDP Calculation Method
GDP is the total value added from all goods and services produced within a country. It is calculated by summing up the value-added generated during production processes. To understand GDP calculations, we must first understand how value-added is derived.
Value-Added Calculation Example: Rice Production and Sales
1.Farmers Growing Rice
Farmers purchase fertilizers and seeds for $100 and sell rice to wholesalers for $200.
Value-added = $200 - $100 = $100.
2.Wholesalers Selling Rice to Retailers
Wholesalers purchase rice for $200 and sell it to supermarkets for $300.
Value-added = $300 - $200 = $100.
3.Retailers Selling Rice to Consumers
Retailers sell rice to consumers for $400.
Value-added = $400 - $300 = $100.
Total Value-Added**
Farmers' $100 + Wholesalers' $100 + Retailers' $100 = $300.
By summing up all value-added at different production stages, the GDP of a country can be determined.
The Principle of Equivalence
Besides production, GDP can also be calculated through expenditure and distribution methods.
The three approaches—"Production," "Expenditure," and "Distribution"—produce equivalent results, known as the Principle of Equivalence.
GDP calculated through expenditures is called Gross Domestic Expenditure (GDE).
GDP calculated through income distribution is called Gross Domestic Income (GDI).
Both GDE and GDI are consistent with the production-based GDP, providing a comprehensive view of economic conditions.
Difference Between GDP and GNP
A related concept to GDP is Gross National Product (GNP).
While GDP reflects the total value added of goods and services produced within a country, GNP measures the value added generated by nationals, including overseas activities.
Types of GDP
Nominal GDP
Calculated using current prices.
Reflects both economic growth and price fluctuations (e.g., inflation).
Real GDP
Adjusted to exclude the effects of price changes.
Provides a more accurate representation of economic growth.
Three Factors Affecting GDP Changes
Per Capita GDP
Higher economic growth leads to increased per capita GDP.
Innovations and booming industries can drive per capita GDP growth.
Price Changes
Inflation or exchange rate fluctuations can raise nominal GDP.
Real GDP is necessary to evaluate actual economic growth.
Population Changes
Population growth typically leads to higher GDP due to more participants in economic activities.

Relationship Between GDP and Forex (FX) Trading
GDP has a limited impact on market movements compared to leading indicators like U.S. employment reports or CPI.
While GDP is a critical economic figure, it is a lagging indicator, representing past economic activities, and is less predictive of market trends.
