    • 14.1: Introduction to the Aggregate Demand/Aggregate Supply Model
      This page explores the macroeconomic model of aggregate supply and demand, focusing on its impacts on economic growth, unemployment, and inflation. It addresses the housing bubble and financial crisis leading to the Great Recession, emphasizing the U.S. economy's volatility. The chapter lays the groundwork for understanding economic cycles and the relationships between macroeconomic variables, setting the stage for an analysis of Keynesian and Neoclassical viewpoints on macroeconomic behavior.
    • 14.2: Macroeconomic Perspectives on Demand and Supply
      This page contrasts Say's Law and Keynes' Law in economics, focusing on their differing views on supply and demand. Say’s Law suggests that supply generates demand over the long term, while Keynes’ Law argues that demand influences supply in the short term. The discussion emphasizes the importance of both theories for a complete understanding of macroeconomics, highlighting their respective short-term and long-term implications.
    • 14.3: Building a Model of Aggregate Demand and Aggregate Supply
      This page covers the aggregate demand and aggregate supply (AD-AS) model, crucial for macroeconomic analysis. It details the upward-sloping aggregate supply curve and downward-sloping aggregate demand curve, emphasizing their equilibrium points and influences like wealth and interest rates. The implications of equilibrium positions on inflation and unemployment are discussed, highlighting how different segments of the AS curve reflect varying economic conditions.
    • 14.4: Shifts in Aggregate Supply
      This page examines the factors influencing shifts in the aggregate supply (AS) curve, emphasizing productivity growth and input price changes. It explains that productivity growth shifts the AS curve rightward, boosting output, while higher input prices shift it leftward, lowering GDP and risking recession and inflation. Additionally, the page highlights the effects of unexpected events, such as natural disasters or pandemics, on labor supply and subsequent AS curve adjustments.
    • 14.5: Shifts in Aggregate Demand
      This page covers aggregate demand (AD) and its influencing factors, such as imports, consumer and business confidence, and government policy. It highlights how imports decrease AD and how confidence changes can shift the AD curve. The discussion includes tax cuts' political and economic context, noting their effectiveness is contingent on accompanying spending cuts and economic conditions.
    • 14.6: How the AD/AS Model Incorporates Growth, Unemployment, and Inflation
      This page introduces the aggregate demand/aggregate supply (AD/AS) model, highlighting its significance in illustrating economic growth, unemployment, and inflation. It encapsulates the dynamic relationships among these macroeconomic goals from both Keynesian and classical viewpoints, showcasing long-term growth through supply shifts and business cycle fluctuations in GDP.
    • 14.7: Keynes’ Law and Say’s Law in the AD/AS Model
      This page covers the AD/AS model, detailing its three zones: Keynesian (low output, high unemployment), intermediate (trade-off between output and inflation), and neoclassical (output near potential GDP, low unemployment). It highlights how shifts in aggregate demand influence economic output and price levels. Additionally, it discusses the pandemic's effects on both supply and demand in the U.S. economy.
    • 14.8: Key Terms
      This page explores macroeconomic principles, emphasizing aggregate demand (AD) and aggregate supply (AS). It details the AD curve's depiction of spending across price levels and the AS curve's representation of output. The aggregate demand/aggregate supply model is introduced, alongside potential GDP, full-employment GDP, and AS curve classifications (Keynesian, intermediate, and neoclassical).
    • 14.9: Key Concepts and Summary
      This page explores macroeconomic demand and supply, highlighting the differences between neoclassical and Keynesian theories. It introduces the aggregate demand (AD) and aggregate supply (AS) model, discussing short-run and long-run behaviors, the downward slope of AD, and concepts like stagflation and growth.
