ποΈ Net exports in GDP
Learn how net exports (exports minus imports) affect GDP, why trade deficits and surpluses matter, and how international trade shapes economic growth.
ποΈ GDP vs GNP vs GNI
Understand the differences between GDP (Gross Domestic Product), GNP (Gross National Product), and GNI (Gross National Income), and learn why each matters for economic measurement.
ποΈ How GDP growth rate is calculated
Learn how economists calculate GDP growth rates, why they measure both nominal and real growth, and how to interpret quarterly and annual growth data.
