Calculate Equilibrium National Income and Interest Rate using IS-LM Model

In this video, we solve a numerical problem to find the equilibrium national income (\(Y\)) and the interest rate (\(r\)) for an economy. We use the fundamental principles of macroeconomics, specifically the IS-LM model, to find the simultaneous equilibrium in both the goods market and the money market.The video covers:IS Curve Derivation: We show how to derive the IS curve equation from the aggregate savings, investment, and tax functions. The IS curve represents the equilibrium in the goods market where investment equals savings.LM Curve Derivation: We then derive the LM curve equation from the money demand and money supply functions. The LM curve represents the equilibrium in the money market where the demand for money equals the money supply.Simultaneous Equilibrium: By solving the IS and LM equations simultaneously, we find the unique combination of national income Y and interest rate r where both the goods and money markets are in equilibrium.This video is a great resource for students studying macroeconomics and for anyone who wants to understand how to apply the IS-LM model to a practical problem. #Macroeconomics #IS-LM_Model Equilibrium National Income Equilibrium Interest Rate Goods Market Equilibrium Money Market Equilibrium
