Microeconomics Chapter 3: Productivity Concepts

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.
