Aggregate demand and aggregate supply model
A model that explains short run fluctuations in real gdp and the price level
Aggregate demand curve
A curve that shows the relationship between the price level and the quantity of real GDP demanded by households, firms, and the govt
Short run aggregate supply curve
A curve that shows the relationship in the short run between the price level and the quantity of real gdp supplied by firms
Why is the aggregate demand curve downward sloping?
Because a fall in the price level increases the quantity of real GDP demanded
Wealth effect
When price level rises, the nominal value of household wealth falls, reducing consumption and vice versa
Interest rate effect
When PL rises, households and firm will borrow more money, leading to higher interest rates, which discourages consumption
International trade effect
When price level rises relative to other price levels, US goods become more expensive, and reduce consumption of US exports
Variables that shift the AD curve
Changes in govt policies, changes in expectations of households and firms, and changes in foreign exports
Monetary policy
Actions fed reserve takes to manage money supply and interest rates to pursue macroeconomic policy objectives
Fiscal policy
Changes in federal taxes and purchases that are intended to achieve macroeconomic policy objectives
Long run aggregate supply curve
A curve that shows the relationship in the long run between the price level and the quantity of real GDP supplied
Why is the LRAS a vertical line?
Because changes in the PL do not affect the number of workers, the capital stock or technology, PL in the long run does not affect real GDP
Why is the SRAS upward sloping?
Because firms and workers cannot predict the future price level exactly due to sticky contracts, menu costs, and firms are slow to adjust wages
What does a higher price level normally mean for workers and firms?
Higher profits, increased supply and higher wages
What variables shift the SRAS?
Increases in labor force, technological change, expected changes in future price level, adjustments of workers and firms to errors in past expectations about PL, and supply shocks
