Study Notes

Demand

Market: A platform where buyers and sellers interact for economic transactions.
Demand: The quantity of a good a consumer or group is willing and able to purchase.
Prices increasing leads to decreased demand (and vice versa), assuming other factors remain the same.
Negative relationship due to:
- Income effect: Price decrease increases consumer's real income, leading to higher demand.
- Substitution effect: Price of a good decreases, making it more attractive relative to other goods.
- Diminishing marginal returns: As quantity demanded increases, the willingness to pay per unit decreases.
Total Market Demand: Sum of the individual demands for all goods in a market.
Change in Demand vs. Change in Quantity Demanded:
- Change in price causes movement along the demand curve.
- Change in other factors causes a shift of the demand curve.
- Factors affecting the shift:
  - Income (normal goods increase in demand with income increase)
  - Substitute goods (price change in one good affects demand for the other)
  - Complementary goods (goods consumed together, demand is linked)
  - Taste and preferences, population size and changes in income distribution.

Supply

Supply: The quantity of a good or service producers are willing and able to sell at a given price.
Price increase leads to increased supply
Factors affecting the shift:
- Production costs: increasing costs shift supply curve left.
- Productivity: improvements shift supply curve right.
- Expectations of future prices
- Taxes and subsidies: taxes increase costs, shifting left; subsidies decrease costs, shifting right
- Prices of related goods: the producers have a choice to produce a certain good in greater quantity.
Market Supply: Sum of individual supplies for a good.

Equilibrium

Equilibrium: Where supply and demand intersect. The market will remain in equilibrium until external factors change it.
Equilibrium point is where the quantity consumers want to purchase and producers want to sell are the same.

Opportunity cost

Opportunity cost: The next best alternative foregone.

Market Efficiency

Consumer Surplus: Difference between what consumers are willing to pay and the price they actually pay.
Producer Surplus: Difference between the price a producer receives for a good and the cost they have to produce it.

Price Elasticity of Demand (PED)

PED: Responsiveness to a change in price.
Positive value indicates that the two goods are substitutes.
A negative value indicates the two goods are complements.
Determinants:
- Availability of substitutes
- Proportion of income
- Luxury/necessity
- Time to respond

Price Elasticity of Supply (PES)

Measure of responsiveness to a change in price of a good or service
PES is always positive, because price and quantity supplied are positively related
Determinants:
- Cost of production
- Time period considered
- Ability to store stock
