Issues Addressed in Microeconomics
An interactive exploration of the fundamental concepts that explain how individuals and firms make decisions in a world of scarcity.

1. How Does Microeconomics Address Supply and Demand Issues?
Supply and demand is the core model of microeconomics, explaining how prices and quantities of goods are determined in a competitive market. The model shows the relationship between the quantity of a good that producers are willing to sell at various prices and the quantity that consumers are willing to buy. The intersection of these two forces determines the market's equilibrium price and quantity. Use the buttons below to see how shifts in supply or demand affect the market.
2. What Market Structures Are Analyzed in Microeconomics?
Microeconomics categorizes markets based on their structure, which influences how firms behave and compete. The structure is defined by characteristics like the number of firms, the similarity of their products, and the ease of entering or exiting the market. These structures range from perfect competition, with many firms and identical products, to monopoly, where a single firm dominates. Click on a card to learn more about each structure.
Perfect Competition
- Many small firms
- Identical products
- No barriers to entry
- Firms are price takers
Monopolistic Competition
- Many firms
- Differentiated products
- Low barriers to entry
- Some price control
Oligopoly
- Few large firms
- Identical or differentiated products
- High barriers to entry
- Interdependent decisions
Monopoly
- One single firm
- Unique product
- Very high barriers to entry
- Firm is a price setter

3. How Do Microeconomists Study Consumer Behavior?
Consumer theory studies how individuals make spending decisions to maximize their satisfaction, or "utility," given their budget constraints. It assumes consumers are rational and aim to get the most value for their money. This involves trade-offs, as buying more of one good means affording less of another. Use the sliders below to see how you might allocate a budget to maximize your utility from buying coffee and croissants.

4. What Role Does Government Policy Play in Microeconomic Issues?
Governments intervene in markets to correct perceived market failures and achieve social goals that the free market may not. These interventions, such as price controls, taxes, and subsidies, can significantly alter market outcomes. While often intended to protect consumers or producers, these policies can have unintended consequences, like shortages or surpluses. Select a policy below to see its effect on a market.
5. How Does Microeconomics Address Production and Cost Problems?
This area of microeconomics examines how firms make decisions about production and cost to maximize profit. It involves understanding the relationship between inputs (like labor and capital) and output, as well as analyzing different types of costs (fixed, variable, marginal). A key principle is that firms will produce up to the point where the cost of producing one more unit (marginal cost) equals the revenue it brings in (marginal revenue). Adjust the production quantity below to find the profit-maximizing output level.
