In this chapter you will learn the IS curve,and its relation to the Keynesian Cross the Loanable Funds model the LM curve,and its relation to the Theory of Liquidity Preference how the IS-LM model determines income and the interest rate in the short run when P is fixed CHAPTER 10 Aggregate Demand I slide 1

1 Introduction Chapter 9 introduced the model of aggregate demand and aggregate supply. ■Long run prices flexible 一 output determined by factors of production technology 一 unemployment rate equals its natural rate ▣Short run -prices fixed output determined by aggregate demand unemployment is negatively related to output CHAPTER 10 Aggregate Demand I slide 3
CHAPTER 10 Aggregate Demand I slide 3 Introduction ▪ Chapter 9 introduced the model of aggregate demand and aggregate supply. ▪ Long run – prices flexible – output determined by factors of production & technology – unemployment rate equals its natural rate ▪ Short run – prices fixed – output determined by aggregate demand – unemployment is negatively related to output 1
Introduction This chapter develops the IS-LM model,the theory that yields the aggregate demand curve. We focus on the short run and assume the price level is fixed. CHAPTER 10 Aggregate Demand I slide 4
