As the price decreases, the quantity demanded increases
#3
What is the concept of 'opportunity cost' in microeconomics?
The monetary cost of an economic decision
The value of the best alternative forgone when a decision is made
The total cost of producing a good or service
The cost of inputs used in the production process
#4
What is the concept of 'elasticity of supply' in microeconomics?
The responsiveness of quantity demanded to changes in price
The responsiveness of quantity supplied to changes in price
The relationship between income and consumption
The impact of government subsidies on market equilibrium
#5
In microeconomics, what does the term 'utility' refer to?
The total revenue generated by a firm
The satisfaction or pleasure derived from consuming goods and services
The production efficiency of a firm
The elasticity of demand for a good
#6
In economics, what is the formula for calculating elasticity?
Percentage change in quantity demanded / Percentage change in price
Percentage change in price / Percentage change in quantity demanded
Total quantity demanded / Total price
Total price / Total quantity demanded
#7
What is the difference between explicit and implicit costs?
Explicit costs are monetary, while implicit costs are not
Explicit costs are incurred in the long run, while implicit costs are incurred in the short run
Explicit costs are opportunity costs, while implicit costs are accounting costs
Explicit costs are fixed, while implicit costs are variable
#8
What is the difference between a normal good and an inferior good?
Normal goods have an elastic demand, while inferior goods have an inelastic demand
Normal goods are luxury items, while inferior goods are basic necessities
Normal goods have a positive income elasticity, while inferior goods have a negative income elasticity
Normal goods have a negative cross-price elasticity, while inferior goods have a positive cross-price elasticity
#9
In microeconomics, what is the Cobb-Douglas production function used to represent?
Perfect competition
Monopoly
Production with two or more inputs
Elasticity of demand
#10
What is the concept of 'price discrimination' in microeconomics?
Selling a good at different prices based on the seller's preferences
Charging different prices for the same good to different consumers based on various factors
Setting a single price for a good to maximize profits
Reducing prices to attract more consumers
#11
According to the law of diminishing marginal returns, what happens as additional units of a variable input are added to a fixed input?
Total output increases continuously
Marginal product increases
Total output initially increases but eventually decreases
Marginal product remains constant
#12
What is the key difference between short-run and long-run production functions?
Short-run functions consider only fixed inputs, while long-run functions consider both fixed and variable inputs
Short-run functions have a constant scale of production, while long-run functions allow for changes in scale
Short-run functions are applicable to monopolistic competition, while long-run functions are applicable to perfect competition
Short-run functions assume perfect elasticity of supply, while long-run functions assume imperfect elasticity
#13
What is the concept of 'consumer surplus' in microeconomics?
The difference between the price paid by consumers and the cost of production
The additional satisfaction gained by consumers from consuming one more unit of a good
The difference between the maximum price consumers are willing to pay and the price they actually pay
The total revenue generated by consumers in the market
#14
In the context of game theory, what is a dominant strategy?
A strategy that is most likely to lead to a Nash equilibrium
A strategy that is always the best choice for a player, regardless of the actions of other players
A strategy that maximizes the payoffs of all players in a cooperative game
A strategy that is strictly dominated by other strategies
#15
What is the primary goal of antitrust laws in microeconomics?
To encourage collusion among firms
To promote monopolies for efficiency
To prevent anti-competitive behavior and protect consumer welfare
To limit government intervention in the market
