Gross Domestic Product (GDP)

Gross Domestic Product (GDP) represents the total monetary value of all goods and services produced within a country during a specific period. It acts as a vital indicator of a nation's economic health and size, enabling comparisons over time to assess whether the economy is expanding or contracting. GDP includes all types of spending and output, such as government expenditures, consumer spending, business investments, and net exports (the difference between total exports and imports). Although GDP is typically calculated on an annual basis, it is frequently reported quarterly and can have a significant impact on financial markets.

The GDP of a country accounts for all production within its borders, regardless of asset ownership or the nationality of the labor involved. This differs from Gross National Product (GNP), which measures the output generated by a country's citizens, irrespective of where that production takes place. The growth of GDP is evaluated in real terms, meaning that the effects of inflation are excluded.

The concept of GDP was first introduced in the late 18th century, with the modern interpretation developed by economist Simon Kuznets in 1934. It was subsequently adopted as the primary measure of economic performance at the Bretton Woods conference in 1944.

The term “Gross” in GDP signifies that all products are included, regardless of their later use, while “Net” excludes products used to replace depreciated assets. The term “Domestic” indicates that only goods and services produced within a country’s borders are counted, irrespective of the producer's nationality.

GDP can be calculated using three main methods: the production approach (which sums the value added at each stage of production), the expenditure approach (which totals purchases made by final users), and the income approach (which aggregates incomes generated by production). The expenditure approach is the most commonly utilized, represented by the formula: GDP = consumption + investment + government spending + (exports - imports).

GDP is an essential measure of economic growth and health, influencing financial markets and guiding policymakers in decisions related to interest rates, taxes, and trade policies. An increasing GDP generally indicates a robust economy, leading to higher employment and consumer spending, while a declining GDP suggests economic contraction, resulting in decreased production and job losses.

The GDP growth rate reflects the percentage change in real GDP from one period to another, indicating whether the economy is growing or shrinking. GDP per capita, calculated by dividing nominal GDP by the total population, provides an average economic output per person, offering insights into living standards within a country. GDP data is typically released quarterly, with the first estimate available at the end of the month following the conclusion of a calendar quarter.
