Flashcards

Perfect Competition

A market structure characterized by many small firms, homogeneous products, free entry and exit, and perfect information. Firms are price takers, meaning they have no control over the market price.

Monopoly

A market structure with a single seller and significant barriers to entry, allowing the monopolist to influence the market price.

Consumer Behavior

The study of how individuals make choices about allocating their limited resources, considering factors like preferences, budget constraints, and prices.

Utility

The satisfaction or benefit derived from consuming goods or services. It's central to understanding consumer choices.

Externalities

A situation where the production or consumption of a good or service affects a third party who is not directly involved in the transaction. They can be positive (e.g., education) or negative (e.g., pollution).

Market Failures

A situation where markets fail to efficiently allocate resources due to factors like externalities or imperfect information. This often requires government intervention.

Supply

The quantity of a good or service that producers are willing and able to sell at different price points. It is generally upward-sloping as price increases.

Production Costs

Costs incurred by firms in the production process. These can include fixed costs (e.g., rent) and variable costs (e.g., raw materials) that change with output levels.

Study Notes

Basic Concepts

  • Microeconomics examines the behavior of individual economic agents (households, firms, markets) and their decisions regarding scarce resources.
  • It focuses on individual markets, not macroeconomic issues.
  • Key areas include supply and demand, production, costs, and market structures like perfect competition and monopoly.
  • Microeconomics helps understand price determination, resource allocation, and market failures.

Supply and Demand

  • Supply and demand are fundamental to price determination in markets.
  • Demand is the quantity consumers are willing and able to buy at various prices (inverse relationship).
  • Supply is the quantity producers are willing and able to sell at various prices (direct relationship).
  • Market equilibrium occurs where quantity demanded equals quantity supplied, establishing equilibrium price and quantity.

Elasticity

  • Elasticity measures the responsiveness of one variable to changes in another.
  • Types include price elasticity of demand, price elasticity of supply, income elasticity of demand, and cross-price elasticity of demand.
  • Price elasticity of demand shows the percentage change in quantity demanded due to a percentage change in price.
  • Inelastic demand: price change leads to a smaller proportional change in quantity demanded. Elastic demand: price change leads to a larger proportional change in quantity demanded.
  • Elasticity is crucial for understanding market impacts of price or other changes.

Production and Costs

  • Production transforms inputs (labor, capital, raw materials) into outputs.
  • Firms aim to minimize costs while maximizing output.
  • Cost curves illustrate fixed costs, variable costs, total costs, average costs, and marginal costs.
  • Cost curves guide output decisions, pricing, and resource allocation by firms.

Market Structures

  • Different market structures influence firm behavior and market outcomes.
  • Perfect competition: many small firms, homogeneous products, free entry/exit, perfect information; firms are price takers.
  • Monopoly: single seller, significant barriers to entry; monopolist can influence market price.
  • Other structures include monopolistic competition and oligopoly, each with unique characteristics relating to firms, differentiation, and market power.

Consumer Behavior

  • Consumer behavior studies individual choices allocating limited resources (time, income).
  • Key factors are preferences, budget constraints, and prices.
  • Consumer choice theory shows how individuals maximize utility subject to budget constraints.
  • Utility represents the satisfaction or benefit from consumption.

Externalities and Market Failures

  • Externalities occur when production or consumption impacts third parties not involved in the transaction.
  • Externalities can be positive (education) or negative (pollution).
  • Market failures arise when markets inefficiently allocate resources, often due to externalities.
  • Government intervention addresses market inefficiencies.

Game Theory

  • Game theory analyzes strategic interactions between rational agents.
  • It models situations where outcomes depend on choices made by multiple participants.
  • Game theory applies to firms' interactions and market competition.

Applications

  • Microeconomics has diverse applications in various fields.
  • Examples include business decisions, public policy analysis, and understanding market dynamics.
  • Tools aid in optimal pricing, resource analysis, and assessing the impact of regulations and policies.
