5 Questions
What is the fundamental economic problem that microeconomics attempts to address, and how is it related to the concept of scarcity?
The fundamental economic problem is the unlimited wants of individuals and the limited resources available to meet those wants. This problem is related to the concept of scarcity, which refers to the fact that the needs and wants of individuals are unlimited, but the resources available to satisfy those needs and wants are limited.
What is the Law of Demand, and how does it relate to the concept of opportunity cost?
The Law of Demand states that as the price of a good or service increases, the quantity demanded decreases, ceteris paribus. This law is related to the concept of opportunity cost, as the decision to purchase a good or service at a higher price means forgoing the opportunity to purchase something else with that money.
What is the Production Possibility Frontier (PPF), and what does it illustrate?
The Production Possibility Frontier (PPF) is a graph that shows the various combinations of two goods that can be produced given the available resources and technology. It illustrates the trade-offs between the production of two goods and the concept of scarcity.
What is the difference between perfect competition and monopolistic competition, and how do these market structures affect the behavior of firms?
Perfect competition is a market structure characterized by many firms, free entry and exit, and identical products. Monopolistic competition is a market structure characterized by many firms, free entry and exit, and differentiated products. The key difference is that in perfect competition, firms have no market power, whereas in monopolistic competition, firms have some market power due to product differentiation.
What is an externality, and how does it relate to the concept of market failure?
An externality is an unintended consequence of economic activity that affects third parties. It is a form of market failure, as the market does not take into account the external effects of economic activity, leading to a mismatch between the private and social costs or benefits of a particular activity.
Study Notes
Microeconomics
Definition and Scope
- Microeconomics is the study of individual economic units, such as households, firms, and markets.
- It examines the behavior and decision-making processes of these units in allocating limited resources to meet their unlimited wants.
Key Concepts
- Scarcity: The fundamental economic problem of unlimited wants and limited resources.
- Opportunity Cost: The value of the next best alternative forgone when making a choice.
- Rational Choice: The assumption that individuals make decisions based on their preferences and the available options.
Consumer Behavior
- Demand: The quantity of a good or service that consumers are willing and able to purchase at a given price level.
- Law of Demand: The inverse relationship between the price of a good and the quantity demanded.
- Consumer Equilibrium: The point at which the quantity demanded equals the quantity supplied.
Production and Cost
- Production Possibility Frontier (PPF): A graph showing the various combinations of two goods that can be produced given the available resources and technology.
- Law of Diminishing Returns: The decrease in marginal output as additional units of a variable input are added to a fixed input.
- Cost Minimization: The goal of firms to minimize the cost of producing a given output level.
Market Structure
- Perfect Competition: A market structure characterized by many firms, free entry and exit, and identical products.
- Monopoly: A market structure characterized by a single firm, barriers to entry, and a downward-sloping demand curve.
- Monopolistic Competition: A market structure characterized by many firms, free entry and exit, and differentiated products.
Market Failure
- Externalities: The unintended consequences of economic activity that affect third parties.
- Public Goods: Goods and services that are non-rivalrous and non-excludable.
- Information Asymmetry: The unequal distribution of information between buyers and sellers.
Welfare Economics
- Pareto Efficiency: A state in which no individual can be made better off without making someone else worse off.
- Consumer Surplus: The difference between the maximum willingness to pay and the market price.
- Producer Surplus: The difference between the market price and the minimum acceptable price.

Market Failure
- Externalities are unintended consequences of economic activity that affect third parties.
- Public Goods are non-rivalrous and non-excludable, meaning their consumption by one individual does not reduce their availability to others.
- Information Asymmetry occurs when there is unequal distribution of information between buyers and sellers.
Welfare Economics
- Pareto Efficiency occurs when no individual can be made better off without making someone else worse off.
- Consumer Surplus is the difference between the maximum willingness to pay and the market price.
- Producer Surplus is the difference between the market price and the minimum acceptable price.
