Macroeconomics: Aggregate Demand and Supply Analysis

Understanding how the economy functions requires mastering the relationship between total demand and total supply. This fundamental model is essential for interpreting economic news and policy decisions. By the end of this course, you will have a solid conceptual and practical grasp of the Aggregate Demand and Aggregate Supply (AD-AS) model. You will be able to identify the key factors that cause shifts in these curves and use the model to analyze the effects of real-world economic events and government intervention. What you'll learn: * Understand the core definitions and components of Aggregate Demand (consumption, investment, government spending, net exports). * Define Aggregate Supply, distinguishing between the short-run and long-run AS curves and their determinants. * Analyze how the intersection of AD and AS determines equilibrium output, employment, and the general price level. * Apply the AD-AS model to evaluate the impact of fiscal policy (taxes and spending) and monetary policy tools on the economy. * Practice using the multiplier effect to calculate the total change in equilibrium output resulting from initial changes in spending. The course begins by establishing the foundational terminology and components of both demand and supply, then progresses through the mechanics of equilibrium determination and the analysis of external shocks. Written exercises and examples reinforce the application of these models. This course is designed for absolute beginners in macroeconomics, students, or anyone seeking a clear, text-based introduction to how supply and demand operate at a national level.
