Key points
There is a four-step process that allows us to predict how an event will affect the equilibrium price and quantity using the supply and demand framework.
Step one: draw a market model (a supply curve and a demand curve) representing the situation before the economic event took place.
Step two: determine whether the economic event being analyzed affects demand...

Key points
The aggregate demand/aggregate supply model is a model that shows what determines total supply or total demand for the economy and how total demand and total supply interact at the macroeconomic level.
Aggregate supply is the total quantity of output firms will produce and sell—in other words, the real GDP.
Aggregate demand is the...
Key points
Supply and demand curves intersect at the equilibrium price. This is the price at which we would predict the market will operate.
Where demand and supply intersect
Because the graphs for demand and supply curves both have price on the vertical axis and quantity on the horizontal axis, the demand curve and supply curve for a particular good or service can...

In a competitive market, demand for and supply of a good or service determine the equilibrium price.
Equilibrium
MARKETS: Equilibrium is achieved at the price at which quantities demanded and supplied are equal. We can represent a market in equilibrium in a graph by showing the combined price and quantity at which the supply and demand curves intersect.
For example, imagine...
Key points
The expenditure-output model, or Keynesian cross diagram, shows how the level of aggregate expenditure varies with the level of economic output.
The equilibrium in the diagram occurs where the aggregate expenditure line crosses the 45-degree line, which represents the set of points where aggregate expenditure in the economy is equal to output, or national income....
