Study Notes

Price Determination Model

The economic model of price determination in a market is based on the interaction of supply and demand.

Supply Schedule and Supply Curve

The supply schedule is a table that shows the relationship between the price of a good and the quantity supplied.
The supply curve is a graphical representation of the supply schedule, showing the direct relationship between the price of a good and the quantity supplied.

Supply Determination under Perfect Competition

Under the assumption of perfect competition, supply is determined by the production costs and the price of the good.
Firms produce the quantity that maximizes profit, which is where the marginal cost equals the marginal revenue.

Effect of a Rise in Raw Material Costs on the Supply Curve

A rise in the cost of raw materials increases the production cost, leading to a decrease in supply.
The supply curve shifts to the left, indicating that suppliers are less willing to supply the good at each price level.

Aggregate Demand-Aggregate Supply Model

The aggregate demand-aggregate supply model is used to depict the overall performance of an economy in macroeconomics.
The model helps to determine the equilibrium price level and real GDP of an economy.
