Which scenario would most likely result in a shift of the demand curve for electric vehicles to the right?
Which scenario would most likely result in a shift of the demand curve for electric vehicles to the right?
- A significant decrease in the price of gasoline.
- A major technological breakthrough that increases the cost of producing batteries used in electric vehicles.
- An increase in interest rates for auto loans.
- The introduction of a new government tax credit for purchasing electric vehicles. (correct)
What does it mean if the price elasticity of demand for a product is 0.5?
What does it mean if the price elasticity of demand for a product is 0.5?
- The demand is elastic; a small change in price leads to a large change in quantity demanded.
- The demand is unit elastic; a change in price leads to an equal change in quantity demanded.
- The demand is perfectly elastic; any change in price leads to an infinite change in quantity demanded.
- The demand is inelastic; a large change in price leads to a small change in quantity demanded. (correct)

Study Notes
Introduction to Microeconomics
- Microeconomics examines the actions of individual economic actors, including households and firms, and their interactions within markets
- It focuses on specific markets and industries, rather than the overall economy
- Key concepts encompass supply and demand, market equilibrium, elasticity, production costs, and market structures
Supply and Demand
- Supply reflects the link between a good's price and the quantity producers are willing to offer
- Demand illustrates the connection between a good's price and the quantity consumers are willing to buy
- Market equilibrium happens where supply and demand curves intersect, defining market price and quantity
- Demand curve shifters include consumer preferences, income, related goods' prices, and expectations
- Supply curve shifters include input prices, technology, and government regulations
Elasticity
- Price elasticity of demand measures how quantity demanded reacts to price changes
- Elastic demand indicates a substantial quantity change for a slight price change
- Inelastic demand signifies a small quantity change for a substantial price change
- Price elasticity of supply gauges how quantity supplied responds to price changes
Cost and Production
- The production function details the relationship between inputs and output
- Production costs consist of fixed costs (e.g., rent) and variable costs (e.g., labor)
- Total cost is the sum of fixed and variable costs
- Short-run costs differ from long-run costs because some inputs are fixed during the short term
Market Structures
- Perfect competition features numerous buyers and sellers, identical products, and free market entry/exit
- Monopoly has one seller, no close substitutes, and significant barriers to entry
- Monopolistic competition includes many sellers, differentiated products, and relatively easy market entry/exit
- Oligopoly comprises a few large firms, showcasing interdependence, and substantial barriers to entry
Consumer Choice
- Consumers aim to maximize utility (satisfaction) within their budget constraints
- Utility functions illustrate consumer preferences
- Indifference curves depict bundles of goods offering the same satisfaction level
- Budget lines show affordable combinations of goods
Production and Costs
- Firms strive to minimize costs and maximize profits where marginal cost equals marginal revenue
- Production schedules display possible input/output combinations
- Cost curves (e.g., average total cost, average variable cost, marginal cost) illustrate the relationship between cost and output
Market Failure
- Market failure happens when the market mechanism doesn't efficiently allocate resources
- Externalities (positive or negative) cause market failures
- Public goods (e.g., national defense) are difficult to efficiently allocate in markets
Game Theory
- Game theory explores strategic interactions among economic actors
- Payoff matrices show possible outcomes based on choices made by participants
- Nash equilibrium is a solution where no player can improve their outcome given others' strategies
- The Prisoner's Dilemma illustrates conflict between individual and collective rationality
Applications
- Microeconomic principles explain various economic phenomena, including:
- Firm pricing strategies
- Consumer behavior
- Labor market dynamics
- Market regulation
- Government policies impacting markets
- Technology's influence on markets
- Market efficiency versus failure
