Study Notes
Changes in Demand
-
An increase in demand shifts the demand curve rightward, leading to higher prices and greater quantities exchanged.
-
The increase in demand is driven by factors other than the product's price, which only affects the quantity demanded.
-
Primary sources for increasing demand include:
- Improved consumer income increases demand for normal goods.
- Changes in consumer preferences positively affect demand.
- Introduction of substitute goods can enhance demand for a product.
- Positive consumer expectations regarding future prices or income can also stimulate demand.
-
With higher demand, although supply remains unchanged, quantity supplied increases due to price elevation.
-
An initial excess demand at price P0 compels prices to rise as buyers compete for limited products, establishing a new equilibrium at higher price P1 and quantity Q1.
-
Conversely, a decrease in demand shifts the demand curve leftward, resulting in lower prices and quantities exchanged.
-
Possible causes for decreased demand include:
- Lower consumer income reduces demand for normal goods.
- Negative changes in consumer preferences diminish demand.
- The introduction of more attractive substitute goods can decrease demand for the original product.
- Negative consumer expectations can lead to decreased demand.
Changes in Supply
-
An increase in supply shifts the supply curve rightward, resulting in reduced prices and increased quantities exchanged.
-
Elevating supply indicates more goods available at every price or lower prices for each quantity supplied.
-
Factors leading to increased supply exclude changes in the product's price:
- Improved production technology decreases production costs, increasing supply.
- Reduced input costs contribute to a greater supply.
- A rise in the number of suppliers in the market enhances the overall supply.
-
Despite changes in demand affecting equilibrium, supply remains unchanged during such demand shifts.
-
A fall in demand leads to excess supply at price P0, prompting price cuts as sellers attempt to offload excess stock until equilibrium is reached at a lower price P2 and quantity Q2.
