This document explores the determination of output and equilibrium in both the goods and services market and the money market, focusing on the demand side of the economy. It introduces the IS-LM model, illustrating the interaction between the IS curve (goods market) and the LM curve (money market) to achieve equilibrium. The core concepts include variables like consumption, investment, government spending, and money supply. Additionally, it discusses fiscal and monetary policies, emphasizing the importance of maintaining a healthy government budget and economic stability.
