Fundamentals of National Income and Economic Flow

Do you want to understand how economists measure the health and size of an entire economy? Grasping the concepts of national income and economic flow is the essential first step in macroeconomics. This course provides a clear, text-based introduction to the foundational models used to quantify economic output. You will move beyond simple definitions to master the three main methods of calculating national income and interpreting the flow of money, goods, and services throughout a modern economy. What you'll learn: * Understand the two-sector, three-sector, and four-sector models of the circular flow of income. * Apply the Expenditure, Income, and Value Added methods for accurately calculating Gross Domestic Product (GDP). * Differentiate between key aggregates like GDP, GNP, NNP, and understand the difference between nominal and real GDP. * Analyze the role of injections (investment, government spending, exports) and leakages (savings, taxes, imports) in economic stability. * Examine modern critiques of traditional national income metrics, including the concept of Green GDP and limitations of GDP as a measure of welfare. The course begins with defining basic economic terminology and models, then systematically explains the components of national income and the practical steps for calculation using real-world examples. This course is designed for absolute beginners in economics, students, or anyone seeking a solid, prerequisite-free introduction to macroeconomics and national income accounting.
