    Study Notes

    IS/LM Curve Shifts

    • Shifts in the IS curve are caused by changes in autonomous spending (consumption, investment, government spending, net exports).
    • An increase in autonomous spending shifts the IS curve to the right, increasing output and interest rates.
    • A decrease in autonomous spending shifts the IS curve to the left, decreasing output and interest rates.
    • Factors affecting the IS curve include changes in expectations, fiscal policy, and exchange rates.

    IS/LM Curve Shifts - Fiscal Policy

    • Expansionary fiscal policy (increased government spending or tax cuts) shifts the IS curve to the right.
    • Contractionary fiscal policy (decreased government spending or tax increases) shifts the IS curve to the left.
    • These policies impact aggregate demand and output.

    IS/LM Curve Shifts - Monetary Policy

    • Expansionary monetary policy (lowering interest rates) shifts the LM curve to the right.
    • Contractionary monetary policy (raising interest rates) shifts the LM curve to the left.
    • These policies impact money supply and interest rates.

    Shocks

    • Demand Shocks: Changes in aggregate demand (e.g. consumer confidence).
    • Supply Shocks: Changes in aggregate supply (e.g. changes in factor prices, natural disasters).
    • These shocks impact output and inflation, requiring policy adjustments.

    Keynesian Economics

    • Emphasizes the role of aggregate demand in driving economic fluctuations.
    • Argues that market failures can lead to persistent unemployment, requiring government intervention to restore full employment.
    • Focuses on short-run fluctuations and the role of monetary and fiscal policies to correct the economy.
    • Keynesian economics advocates for government intervention via fiscal policy to stabilize the economy during recessions, since markets cannot always self-correct.

    Supply and Demand Shocks

    • Supply shocks affect prices and output simultaneously, potentially resulting in stagflation.
    • Demand shocks affect prices and output but through different channels.

    Policy Responses to Shocks

    • Fiscal Policy: Government spending or tax policies (e.g. stimulus package).
    • Monetary Policy: Central bank actions to influence interest rates and money supply.
    • The appropriate policy response varies based on the type of shock (demand or supply).

    General Equilibrium

    • A state where all markets clear simultaneously, meaning supply equals demand in all sectors of the economy.
    • Factors influencing general equilibrium include prices, preferences, and resource availability.
    • General equilibrium models represent a crucial analytical framework for understanding macroeconomics and microeconomics interactions.

    Liquidity

    • Refers to the ease with which an asset can be converted into cash.
    • Liquidity preference theory suggests that individuals demand money for transactions and speculative purposes, influencing interest rates.
    • Changes in the demand for money due to changes in liquidity lead to fluctuations in interest rates.
