Economics Unit 1 Quiz

Market System

Economic Problems

• Needs vs. Wants: Needs are essential for survival (e.g., food, shelter); wants are desires beyond necessities (e.g., luxury items).
• Scarce Resources: Insufficient resources to meet all needs and wants.
• Production Types:
  • Capital intensive relies on machinery.
  • Labor intensive uses human labor.
• Opportunity Costs: Represents the value of the next best alternative that is forgone when making choices.
• Capital Goods: Used by firms to produce other goods (e.g., machinery).
• Consumer Goods: Consumed directly by individuals.

The Economic Problem

• Arises from unlimited needs/wants against limited resources, leading to three fundamental questions:
  • What to Produce?: Selection of key necessities due to resource constraints.
  • How to Produce?: Decision on production technique (capital vs. labor).
  • For Whom to Produce?: Distribution of produced goods among consumers.

Production Possibility Curve (PPC)

• Illustrates trade-offs between two products, revealing opportunity costs in production.
• Points on Curve:
  • A: Maximum output (full resource utilization).
  • X: Inefficient use (unemployed resources).
  • Y: Unattainable production level with current resources.

Economics Assumptions

Consumer Behavior

• Consumers aim to maximize their satisfaction (utility).
• Factors influencing consumer decisions:
  • Cost/Benefit Analysis: Evaluating choices based on benefits and costs.
  • Irrational Decisions: May occur due to poor calculations, habits, social influence, or emotional attachment to brands.

Firm Behavior

• Firms may not always prioritize profit due to:
  • Managers’ differing objectives from owners.
  • Social or charitable objectives.

Demand Curve

Demand Dynamics

• Definition: Demand is the quantity consumers are willing to buy at different price levels.
• Price Relationship: Inverse relationship; as prices rise, demand usually falls, and vice versa.
• Shifts in Demand Curve: Caused by factors such as:
  • Advertising
  • Consumer income
  • Changes in preferences
  • Prices of substitutes/complements
  • Demographic changes

Supply Curve

Supply Dynamics

• Definition: Supply indicates how much of a good producers are willing to sell at various price levels.
• Price Relationship: Higher prices generally incite increased supply.
• Factors Affecting Supply:
  • Production costs
  • Indirect taxes
  • Subsidies
  • Natural factors (e.g., seasonal changes)
  • Technological advancements

Market Equilibrium

Equilibrium Price Concepts

• Equilibrium Price: Where supply equals demand.
• Excess Demand/Supply: When demand exceeds supply, or vice versa, causes shortages or surpluses.

Price Elasticity of Demand (PED)

• Definition: Measures demand responsiveness to price changes.
• Elastic vs. Inelastic:
  • Inelastic Demand: Change in price leads to smaller change in quantity demanded (PED < 1).
  • Elastic Demand: Change in price leads to greater change in quantity demanded (PED > 1).
• Factors Influencing PED:
  • Availability of substitutes
  • Necessity level of product
  • Proportion of income spent
  • Time frame considered (short run vs. long run)

Total Revenue Relation

• Revenue Calculations: Total revenue changes depending on elasticity; elastic products gain revenue with a price drop, while inelastic products lose revenue.### Price Elasticity of Demand (PED)
• Inelastic products experience total revenue (TR) increase when prices rise and decrease when prices fall.
• PED classifications:
  • Inelastic: Value < 1; rise in price increases TR, fall in price decreases TR.
  • Elastic: Value > 1; rise in price decreases TR, fall in price increases TR.

Price Elasticity of Supply (PES)

• PES measures the responsiveness of supply to price changes.
• Types of PES:
  • Perfectly Elastic: PES = ∞; Producers supply infinite quantity at given price.
  • Perfectly Inelastic: PES = 0; Supply is fixed regardless of price.
  • Unitary Elastic: PES = 1; Quantity supplied changes equal to price changes.
• Formula: PES = % change in quantity supplied / % change in price.
• Example calculation for Vanilla pods shows PES = 0.2, indicating inelastic supply.

Interpretation of PES Values

• Perfectly inelastic: PES = 0
• Perfectly elastic: PES = ∞
• Unitary elastic: PES = 1
• Inelastic: PES < 1
• Elastic: PES > 1

Factors Influencing PES

• Factors of Production: Availability affects responsiveness; more available = more elastic.
• Availability of Stocks: Perishable goods lead to inelastic supply due to short storage life.
• Spare Capacity: More capacity allows quicker production adjustments, leading to elastic supply.
• Time: Longer production times lower PES, making it inelastic (e.g., agricultural products).

Income Elasticity of Demand (YED)

• YED measures how demand changes with income variations.
• Types of goods based on YED:
  • Normal Goods: Demand increases with income; YED > 0.
  • Inferior Goods: Demand decreases as income rises; YED < 0.
  • Luxury Goods: Significant demand increase with rising income; YED > 1.
• Formula: YED = % change in quantity demanded / % change in income.
• Example calculation shows YED of 0.5 for milk, indicating inelastic demand.

Significance of PED and YED

• For Businesses:
  • PED helps forecast revenue changes due to price adjustments.
  • YED aids in anticipating demand shifts related to income changes.
• For Government:
  • Use PED for setting taxes on inelastic goods to maximize revenue.
  • Implement subsidies on necessities to improve access for poorer demographics.

Mixed Economy

• Characterized by both private and public sector involvement in production and services.
• Types of economies:
  • Market Economy: Relies primarily on private sector, minimal government intervention.
  • Command Economy: Entirely government-controlled with high state involvement.
  • Mixed Economy: Combines both sectors, balancing public welfare with market efficiency.

Market Failure

• Occurs when the private sector fails to meet societal objectives, causing negative externalities.
• Forms of market failure:
  • External Costs: Environmental damage from production.
  • Lack of Competition: Limiting consumer choices and increasing prices.
  • Missing Markets: Essential goods/services not provided by private enterprises.
  • Information Failure: Imbalance of information between consumers and producers.

Government Interventions to Mitigate Market Failure

• Implement taxes to address external costs.
• Enforce competition regulations to enhance market dynamics.
• Direct provision of public goods where private sector falls short.
• Educate consumers and producers to correct information disparities.
• Invest in workforce training for improved factor mobility.

Privatization

• The shift from state-owned enterprises to private sector control.
• Forms of privatization:
  • Sale of nationalized industries for efficiency and income generation.
  • Contracting out services to private entities.
  • Sale of government-owned properties to citizens.
• Reasons for privatization include boosting efficiency, reducing political control, and generating revenue for public services.### Effects of Privatization

Consumers

• Improved quality of services and reasonable pricing expected.
• Efficiency increases, although potential tax burdens may arise due to government subsidies.
• Price hikes may occur in some cases.

Workers

• Rise in redundancy levels, leading to job losses.
• Push for flexible working practices among employees.

Business

• Shift towards profit maximization, often at the cost of quality.
• Increased investment in service provision.
• Growth in mergers and acquisitions, expanding diversification.

Government

• Privatization incurs high advertising costs.
• Risk of unwanted hostile takeovers of privatized firms.
• Increased revenue generation allows government focus on efficiency improvements in public services.

Externalities

Types

• Two main types of externalities: negative and positive.

Negative Externalities

• Private costs: Incurred by producers/consumers (e.g., production material costs).
• External costs: Negative spillover effects on third parties (e.g., pollution).
• Social costs: Combination of private costs and external costs.

Positive Externalities

• Private benefits: Profits for producers and satisfaction for consumers.
• External benefits: Positive effects on third parties (e.g., economic growth).
• Social benefits: Sum of private and external benefits.

Contextual Impacts of Externalities

Transport Sector

• Contributes to external costs through greenhouse gas emissions leading to health issues.
• Increased government healthcare spending due to transport-related pollution.

Health Sector

• Positive external benefits as increased government spending on healthcare leads to better treatment and reduced absenteeism.
• Improved productivity due to healthier workers.

Education Sector

• Education enhances employability, innovation, and productivity.
• Increased incomes result in higher tax revenue for government development projects.

Environmental Impact

• Costs linked to pollution and resource depletion threaten sustainability.
• Education fosters innovation in eco-friendly practices.

Vaccinations

• Vaccination reduces disease spread, benefiting third parties by lowering infection rates.

Government Policies to Address Externalities

• Taxation: Higher taxes on polluting firms increase production costs, incentivizing environmental responsibility.
• Subsidies: Lower production costs for beneficial goods increase accessibility and external benefits.
• Fines: Penalties on harmful products reduce consumption, managing external costs.
• Regulations: Legislation raises awareness and reduces harmful activities.
• Pollution permits: Fixed pollution allowances discourage excessive emissions.

Factors of Production

Basic Definitions

• Human capital: Value of workforce skills and experience.
• Labor productivity: Output per unit of input over time.

Types of Production Factors

• Land: Necessary for operations, includes renewable and non-renewable resources.
• Labor: Workforce with varying skill levels; investment in training increases value.
• Capital: Includes working and fixed capital essential for production.
• Enterprise/Entrepreneur: Key decision-makers and risk-takers in business operations.

Production Methods

Labor Intensive vs. Capital Intensive

• Labor Intensive: Relies on more workers than machines; prevalent in developing countries with lower labor costs.
• Capital Intensive: Uses more machines than labor; typical in developed nations with higher capital investment.

Economic Sectors

• Primary sector: Extraction of natural resources (e.g., farming, forestry).
• Secondary sector: Manufacturing of goods from raw materials (e.g., textiles, chemicals).
• Tertiary sector: Service provision (e.g., banking, leisure).

De-Industrialization

• Decline in manufacturing due to increased spending on services and technological advancements.

Productivity and Labor Division

Definitions

• Productivity: Rate of goods produced relative to input.
• Division of labor: Workers specializing in specific tasks to enhance speed and efficiency.

Factors Influencing Productivity

• Land: Improved through fertilizers, drainage, and irrigation.
• Labor: Enhanced through training, motivation, and improved working practices.
• Capital: Technological improvements optimize productivity across all sectors.

Costs in Business

Types of Costs

• Fixed costs: Constant regardless of output (e.g., rent).
• Variable costs: Fluctuate with output level (e.g., raw materials).
• Total costs: Sum of fixed and variable costs.
• Total revenue: Money earned from sales of outputs.
