Aggregate Demand and Supply: Macroeconomic Foundations

The behavior of consumers, businesses, and government drives the entire economy. Understanding these forces is crucial for interpreting economic news and policy decisions. This course provides a foundational understanding of Aggregate Demand (AD), Aggregate Supply (AS), and the mechanisms through which an economy reaches equilibrium. You will learn how changes in consumption and investment affect national income and employment levels. What you'll learn: * Understand the components of Aggregate Demand (C+I+G+NX) and the factors influencing each. * Analyze the Consumption Function, the Saving Function, and the concept of the Multiplier effect. * Apply the simple Keynesian model (AD=AS) to determine equilibrium national income and output in the short run. * Differentiate between short-run and long-run Aggregate Supply (SRAS and LRAS) and the concept of potential output. * Practice calculating equilibrium output and analyzing the impact of autonomous spending changes on the economy. The material begins by defining core macroeconomic terminology and the components of national income accounting. We then move into a detailed analysis of the consumption and investment functions, followed by the mathematical representation of macroeconomic equilibrium. This course is designed exclusively for beginners with no prior knowledge of macroeconomics, economic modeling, or advanced mathematics.
