Study Notes

Productivity and Economic Theories

Average productivity measures output per unit of input, indicating labor efficiency.
Malthusian hypothesis suggests declining average productivity of labor over time.
Living standards correlate positively with population growth according to a second hypothesis.
Technological advancements do not guarantee lasting improvements in living standards.

Comparative Advantage and Trade

Gains from trade can be visualized using the Production Possibility Frontier (PPF), enhancing allocative efficiency.
Absolute advantage leads to specialization where a country excels in producing certain goods, benefiting mutually in trade.
David Ricardo’s theory of comparative advantage asserts that even nations with absolute disadvantages can gain from trade.
Comparative advantage promotes specialization based on lower productivity gaps.

Supply and Market Equilibrium

Market equilibrium occurs when quantity supplied equals quantity demanded (Qs = Qd), stabilizing prices.
The equilibrium price is the market-clearing price, where the quantity bought equals the quantity sold.
Disequilibria (surpluses and shortages) can occur but are generally temporary in competitive markets.
A surplus emerges when the market price is higher than equilibrium, leading to downward price adjustments.
A shortage arises when the quantity demanded surpasses supply, resulting in upward price adjustments.

Dynamics of Demand and Supply Shifts

An increase in demand leads to a higher equilibrium price and quantity.
An increase in supply results in a lower equilibrium price and a higher quantity.
Price elasticity of supply indicates how responsive sellers are to price changes.
Elastic supply means significant changes in quantity supplied with price variation, while inelastic supply reflects minimal changes.

Market Efficiency and Equity

Markets are assessed on allocative efficiency and fairness (equity) of resource distribution.
Allocative efficiency means resources are effectively allocated without surpluses or shortages.
Equity involves fairness in resource distribution, where contributions relate to capabilities, and needs are considered.
Pareto efficiency ensures no one can be better off without making someone else worse off.

Measuring Market Efficiency

Consumer surplus reflects the difference between what consumers are willing to pay and market price.
Producer surplus indicates the difference between market price and producers' minimum acceptable price.
Neoclassical economics emphasizes rational decision-making focused on self-interest and utility maximization.

Budget Constraint and Consumer Choices

A consumer's budget constraint limits total spending to their income level based on prices of goods and services.
The budget line represents consumption bundles affordable within a consumer's budget.
Changes in income or prices shift the budget line upwards (income increase) or downwards (price increase).
Consumers aim to maximize utility while adhering to their budget constraints, affecting their choice of goods.

Indifference Curves and Preferences

Indifference curves illustrate consumer preferences, showing combinations of goods providing equal satisfaction.
Perfect complements create L-shaped indifference curves, indicating that utility depends on quantities of both goods consumed.
The marginal rate of substitution (MRS) remains constant along specific indifference curves, influencing consumer choice behavior.
