Microeconomics

What factors can shift the supply curve for goods?

Factors include input costs, technology improvements, number of firms, and expectations of future prices.

What causes price ceilings to create shortages?

Price ceilings set below equilibrium prevent prices from rising to equilibrium, leading to excess demand.

What is the difference between a shift and a movement along the demand curve?

Movements occur due to price changes, while shifts occur from changes in factors like income and preferences.

What happens to the equilibrium price and quantity when demand shifts right?

Equilibrium price increases and equilibrium quantity increases.

What do simultaneous shifts in demand and supply reveal about equilibrium quantity?

The equilibrium quantity will change, but the direction of the price change depends on which curve shifts more.

How does increased consumer income affect demand for normal goods?

Demand for normal goods increases when consumer income increases.

In perfect competition, how do firms decide how much to produce in the short run?

Firms decide based on marginal cost and marginal revenue.

What economic outcome occurs in perfect competition in the long run?

Firms make zero economic profit as entry and exit drive the price to where total revenue equals total cost.

What sets monopolies apart from firms in perfect competition regarding pricing?

Monopolies set prices above marginal cost due to significant market power.

How does the LRATC curve illustrate economies of scale?

The LRATC curve shows decreasing costs per unit as output increases until diseconomies occur.

What is the profit maximization rule for a monopolist?

A monopolist maximizes profit by producing where marginal cost equals marginal revenue.

What characterizes monopolistic competition?

Monopolistic competition features product differentiation, allowing firms some degree of market power.

How does marginal revenue relate to the demand curve for firms with downward-sloping demand?

Marginal revenue is always less than price because lowering the price is necessary to sell additional units.

What effect do price floors have on market equilibrium?

Price floors set above equilibrium create surpluses due to excess supply.

What leads to market disequilibrium?

Shortages and surpluses caused by shifts in demand and supply lead to price adjustments to regain equilibrium.

What happens to the demand for inferior goods when income decreases?

Demand for inferior goods increases when income decreases.

What is a supply curve?

A supply curve is a graphical representation showing the relationship between the price of a good and the quantity supplied.

What shifts the demand curve to the right?

Factors like increased consumer income, population growth, and favorable changes in consumer preferences can shift the demand curve to the right.

What is equilibrium in a market?

Equilibrium is the point where the quantity demanded equals the quantity supplied, determining the market price.

What are the effects of a price ceiling?

Price ceilings can lead to shortages as they prevent prices from rising to their equilibrium levels.

What role do expectations play in shifting supply curves?

If suppliers expect future prices to rise, they may decrease current supply to sell more later at higher prices.

What is the impact of technology on supply?

Improvements in technology typically lead to an increase in supply by reducing production costs.

What characterizes perfect competition?

Perfect competition is characterized by many firms, identical products, and no barriers to entry or exit.

What is the outcome of a negative externality?

Negative externalities can lead to market failure where the social cost exceeds the private cost, resulting in overproduction.

How do firms in monopolistic competition set prices?

Firms in monopolistic competition set prices based on product differentiation, demand elasticity, and cost considerations.

What is consumer surplus?

Consumer surplus is the difference between what consumers are willing to pay for a good and what they actually pay.
