Global economics is the study of how countries interact through trade, investment, and finance. It examines the flow of goods and services across borders, the impact of international policies, and how economic events in one nation can affect others. Key concepts include trade agreements, exchange rates, and global supply chains. Understanding global economics helps explain issues like inflation, unemployment, and economic growth on a worldwide scale. It also involves analyzing the roles of international organizations such as the International Monetary Fund (IMF) and the World Bank, which aim to promote stability and development in the global economy.
