Economics Basics Quiz

Basic Economic Concepts

• Ceteris Paribus: Assumes all else is held constant when evaluating economic phenomena.
• Economics: The study of scarcity and the choices made in the face of limited resources.
• Opportunity Cost: Represents the value of the best alternative forgone when making a choice.
• Market: Comprises all consumers interested in a particular good or service.
• Market Economy: A capitalist system where buyers and sellers freely determine prices and goods, potentially leading to inequality.
• Command Economy: A system where the government controls all factors of production.
• Scarcity: The condition where resources are insufficient to meet all societal wants, necessitating choices about resource allocation.
• Economic Aggregate: Numeric measures of total economic activity, such as GDP and FDI.
• Factors of Production: Includes land, labor, capital, and entrepreneurship, each rewarded differently (rent, wages, interest, profit).
• Positive Economics: Statements based on facts that can be tested or proven.
• Normative Economics: Statements based on opinions or subjective evaluations.
• Marginal Analysis: Decision-making process focused on the additional benefits and costs of an action.
• Mixed Economy: Combines market and command economy features, allowing some private ownership but with government regulation.

Demand

• Demand Definition: The willingness and ability of consumers to purchase goods and services.

• Effective Demand: Combination of willingness (desire) and ability (financial capacity) to buy.

• Demand Curve:

  • Price is plotted on the vertical axis.
  • Quantity on the horizontal axis.

• Law of Demand (Adam Smith): Inverse relationship between price and quantity; as price increases, quantity demanded typically decreases, and vice versa.

• Demand Curve Characteristics:

  • Substitution Effect: Consumers replace more expensive items with less costly alternatives.
  • Income Effect: As prices rise, consumer purchasing power diminishes, affecting demand.
  • Diminishing Returns: Each additional unit consumed becomes less satisfying, leading to reduced demand at higher prices.

• Non-Price Factors Affecting Demand: Changes in these factors can shift the entire demand curve.

  • Preferences: Individual or collective consumer choices that shape demand.
  • Substitutes and Complements: An increase in the price of one can increase demand for its substitute, while it may decrease demand for its complement.
  • Income Changes: Different categories of goods respond differently to income changes (luxury, normal, necessity, inferior goods).
  • Expectations: Consumer behavior influenced by anticipated future economic conditions.
  • Government Policy: Regulations that may influence consumption patterns.
  • External Factors: Elements such as climate or social trends that can influence demand.

Supply

• Law of Supply: Indicates a positive relationship between price and quantity supplied; as price increases, the quantity supplied typically increases.
• Profit Motive: Encourages suppliers to produce more when the potential for profit rises.
• Economies of Scale: Cost efficiencies gained as production increases, often lowering cost per unit.
• Non-Price Factors Affecting Supply: Changes shift the entire supply curve:
  • Input Costs: Variations in factor prices can directly affect production costs.
  • Expectations: Anticipated price changes influence current supply decisions.
  • Government Policy: Regulation can either foster or hinder supply.
  • Industry Size and Technology: Affects production capabilities and efficiencies.
  • External Shocks: Unforeseen events that affect supply chains or production processes.

Market Equilibrium

• Equilibrium: The point where supply equals demand, facilitating allocative efficiency.
• Surplus and Shortage: Occur when supply exceeds or falls short of demand, respectively.
• Measurement Methods for GDP:
  • Income Method: Total income earned by households from firms.
  • Output Method: Total value of final goods produced.
  • Expenditure Method: GDP calculated as C + I + G + Xn, with C representing consumption, I for investment, G for government spending, and Xn for net exports.

GDP Insights

• Gross Domestic Product (GDP): Total market value of all final goods and services produced within a country in one year; an indicator of economic health.
• Exclusions from GDP:
  • Intermediate goods, secondhand sales, purely financial transactions, and non-commercial services, among others.
• Misrepresentation: Overstating GDP can lead to unrealistic economic assessments.
