Study Notes

Price Mechanism and Market Characteristics

Price mechanism adjusts prices of goods and services through the interaction of supply and demand.
Market failures can occur when the price mechanism fails to allocate resources efficiently.
Public goods, like street lighting, are non-excludable and non-rivalrous, making them difficult for private sectors to supply.
Externalities, both positive and negative, affect the social costs or benefits not reflected in prices, e.g., pollution leads to market inefficiencies.
Monopoly and oligopoly markets can distort prices, limit output, and reduce consumer choice.

Income Inequality and Resource Allocation

Price mechanisms may increase income inequality, where high-income individuals afford more goods while low-income individuals struggle for basics.
Merit goods (e.g., education, healthcare) may be under-provided, while demerit goods (e.g., alcohol, tobacco) may be over-consumed due to price insensitivity.

Information Asymmetry in Markets

Consumers or producers often lack perfect information, causing inefficiencies such as moral hazard, where risks are taken without full consequences.
When demand is elastic, firms might reduce prices to boost sales volume and total revenue.

Elasticity of Demand: Inelastic Demand

Inelastic demand (PED < 1) means that price increases lead to a less than proportional decrease in quantity demanded, allowing firms to raise prices without heavily impacting sales.
Governments impose taxes on inelastic goods (e.g., gasoline) because demand remains stable despite price increases, optimizing tax revenue.

Elasticity of Demand: Factors Influencing PED

Availability of substitutes significantly affects elasticity; goods with many substitutes are elastic, while those with few are inelastic.
Necessities have inelastic demand; essential goods see less variability in demand with price changes, whereas luxury goods have elastic demand.
A larger share of income spent on a good leads to more elastic demand; small expenditure goods typically exhibit inelastic demand.
Time periods influence elasticity; short-term demands are typically more inelastic as consumers have less time to adjust.

Income Elasticity of Demand (YED)

YED assesses the response of quantity demanded to changes in consumer income, calculated by the percentage change in quantity demanded over the percentage change in income.
Normal goods have positive YED; luxury goods (YED > 1) see disproportionate demand increase with rising income, while necessities (0 < YED < 1) see lesser increases.
Inferior goods (YED < 0) encounter decreased demand as income rises as consumers opt for better products.

Economic Impact of YED

High-income elasticity for luxury goods indicates sensitivity to income fluctuations, benefitting during economic booms, but risking sharp demand drops in recessions.
Long-term effects of income changes show potential shifts in consumer preferences from inferior to normal or luxury goods.
YED analysis helps businesses tailor offerings and strategies based on income trends and disparities, influencing product development and sales strategies.

Cross Elasticity of Demand (XED)

XED measures how the quantity demanded of one good reacts to price changes of another good, affecting competitive pricing strategies.

Supply Elasticity Factors

Storage capacity influences elasticity; perishables have inelastic supply due to their inability to be stockpiled.
Complexity in production processes affects responsiveness; simple processes lead to more elastic supplies.
Barriers to market entry dictate supply elasticity; low entry barriers allow for a more elastic market response, while high barriers restrict supply adjustments.
Time lags in production, whether short or long, affect how quickly firms can adjust to price changes based on how quickly they can produce goods.
