What is the law of demand?

• The law of demand indicates that higher prices lead to higher quantity demanded.

• The law of demand states that price and quantity demanded are inversely related.

• The law of demand suggests that demand remains constant regardless of price changes.

• The law of demand states that price and quantity demanded are directly related.

Explain the concept of elasticity of demand.

• Elasticity of demand measures consumer income levels.

• Elasticity of demand refers to the total sales of a product.

• Elasticity of demand is the same as the law of supply.

• Elasticity of demand is a measure of how much the quantity demanded of a good changes in response to a change in its price.

What factors can cause a shift in the demand curve?

• Factors that can cause a shift in the demand curve include changes in income, preferences, prices of related goods, expectations, and number of buyers.

• Improvements in technology

• Changes in weather patterns

• Government regulations on production

Define marginal cost and its significance in production.

• Marginal cost is the average cost of producing all units of a good or service.

• Marginal cost refers to the fixed costs incurred in production.

• Marginal cost is the total cost of production divided by the number of units produced.

• Marginal cost is the cost of producing one additional unit of a good or service, and it is significant for making production and pricing decisions.

What is the difference between fixed and variable costs?

• Fixed costs are only incurred when production is at maximum capacity.

• Fixed costs do not change with production levels, while variable costs do.

• Variable costs are always higher than fixed costs regardless of production.

• Fixed costs vary with production levels, while variable costs remain constant.

Explain the concept of perfect competition.

• Perfect competition is characterized by a single firm dominating the market.

• Perfect competition is a market structure with many small firms selling identical products, where no single firm can influence the market price.

• In perfect competition, firms sell unique products that are not interchangeable.

• Perfect competition allows firms to set their own prices based on demand.

What are the characteristics of a monopoly?

• Multiple sellers in the market

• Characteristics of a monopoly include a single seller, unique products, high barriers to entry, price-making ability, and potential for long-term profits.

How do externalities affect market efficiency?

• Externalities always improve market efficiency.

Define consumer surplus and producer surplus.

• Consumer surplus is the benefit to consumers from purchasing a product at a lower price than they are willing to pay; producer surplus is the benefit to producers from selling a product at a higher price than they are willing to accept.

• Consumer surplus is the difference between the market price and the cost of production; producer surplus is the total sales volume.

• Consumer surplus is the amount of money spent by consumers; producer surplus is the profit made by consumers.

• Consumer surplus is the total revenue generated from sales; producer surplus is the total cost incurred by producers.
