Fundamental Concepts
Microeconomics studies the behavior of individual entities, such as consumers, firms, and industries, in a market economy. It focuses on supply and demand, elasticity, and market equilibrium. Supply refers to the amount of a good or service that producers are willing and able to sell at a given price, while demand refers to the amount that consumers are willing and able to buy at a given price.
Elasticity measures the responsiveness of supply or demand to changes in price. Market equilibrium occurs when the quantity supplied equals the quantity demanded, resulting in a stable price.
Supply and Demand
- The law of supply states that, all else being equal, as the price of a good or service increases, the quantity supplied will increase.
- The law of demand states that, all else being equal, as the price of a good or service increases, the quantity demanded will decrease.
Elasticity
- Price elasticity of demand measures the responsiveness of quantity demanded to changes in price.
- Price elasticity of supply measures the responsiveness of quantity supplied to changes in price.
Market Equilibrium, Microeconomics cheat sheet for final
Market equilibrium occurs when the quantity supplied equals the quantity demanded. At equilibrium, there is no tendency for the price to change.
Consumer Theory
Consumer theory explains how consumers make decisions about what goods and services to buy. It is based on the assumption that consumers are rational and seek to maximize their utility, or satisfaction.
Utility Maximization
Consumers maximize their utility by choosing the combination of goods and services that gives them the highest level of satisfaction, given their budget constraint.
Indifference Curves
Indifference curves are graphical representations of all the combinations of goods and services that give a consumer the same level of utility.
Production Theory
Production theory explains how firms produce goods and services. It focuses on production functions, isoquants, and returns to scale.
Production Functions
A production function shows the relationship between the inputs (e.g., labor, capital) used in production and the output produced.
Isoquants
Isoquants are graphical representations of all the combinations of inputs that produce the same level of output.
Returns to Scale
Returns to scale refer to the relationship between the change in inputs and the resulting change in output.
Market Structures
Market structure refers to the number and size of firms in a market, as well as the barriers to entry and exit. The four main types of market structures are perfect competition, monopoly, oligopoly, and monopolistic competition.
Perfect Competition
Perfect competition is a market structure characterized by a large number of small firms, each producing an identical product. There are no barriers to entry or exit, and firms are price takers.
Monopoly
A monopoly is a market structure characterized by a single firm that is the sole producer of a good or service. Monopolies have high barriers to entry and can set prices above marginal cost.
Oligopoly
An oligopoly is a market structure characterized by a small number of large firms that produce similar products. Oligopolies have high barriers to entry and firms are interdependent in their pricing decisions.
Monopolistic Competition
Monopolistic competition is a market structure characterized by a large number of small firms that produce differentiated products. Firms have some market power and can set prices above marginal cost.
Game Theory
Game theory is a branch of mathematics that studies strategic interactions between rational agents. It is used to analyze situations where the outcome depends on the choices of multiple decision-makers.
Dominant Strategies
A dominant strategy is a strategy that is always the best choice for a player, regardless of the choices of other players.
Nash Equilibrium
A Nash equilibrium is a set of strategies, one for each player, such that no player can improve their outcome by unilaterally changing their strategy.
Prisoner’s Dilemma
The prisoner’s dilemma is a game theory model that illustrates the conflict between individual rationality and collective rationality.
Welfare Economics: Microeconomics Cheat Sheet For Final
Welfare economics is a branch of economics that studies the economic well-being of society as a whole. It focuses on concepts such as economic efficiency, market failures, and government intervention.
Economic Efficiency
Economic efficiency occurs when resources are allocated in a way that maximizes the well-being of society as a whole.
Market Failures
Market failures occur when the market fails to allocate resources efficiently. Examples of market failures include monopolies, externalities, and public goods.
Government Intervention
Government intervention can be used to correct market failures and improve economic efficiency. Examples of government intervention include antitrust laws, regulation, and subsidies.
Essential FAQs
What are the key principles of microeconomics?
Microeconomics focuses on the behavior of individual entities, such as consumers, firms, and markets, and examines how their decisions and interactions shape economic outcomes.
How can I use indifference curves to analyze consumer choices?
Indifference curves represent combinations of goods that yield equal satisfaction to a consumer. By analyzing the slope and shifts of indifference curves, you can predict how consumers will respond to changes in prices and income.
What are the different types of market structures?
Market structures are classified based on the number of buyers and sellers, barriers to entry, and product differentiation. Common market structures include perfect competition, monopoly, oligopoly, and monopolistic competition.
How can game theory be applied to economic decision-making?
Game theory provides a framework for analyzing strategic interactions between individuals or firms. By understanding the concept of dominant strategies and Nash equilibrium, you can predict the likely outcomes of economic decisions.
What is the role of government intervention in correcting market failures?
Government intervention may be necessary to address market failures, such as externalities, public goods, and natural monopolies. Intervention can take various forms, including regulation, taxation, and subsidies.
