Mister Jones was selling his house. The asking price was $220,000, and Jones decided he would take no less than $200,000. After some negotiation, Mister Smith purchased the house for $205,000. Jones' producer surplus is
$5,000.
Joe's demand for spring water can be represented as p = 10 - Q (where p is measured in $/gallon and Q is measured in gallons). He recently discovered a spring where water can be obtained free of charge. His consumer surplus from this water is
$50.

$600.

Suppose a farmer in a perfectly competitive agricultural industry rents land that is uniquely productive in the production of a certain crop. In the long run
the owner of the land receives economic rent while the farmer earns zero economic profit
If a city decides to restrict the number of pizza parlors,
the price of pizza will increase. pizza parlors will make higher profits. total welfare will decrease
The above figure shows supply and demand curves for apartment units in a large city. The area "e" represents
the total variable cost of supplying Q1 units
Without restrictions, the market supply curve is horizontal at P = 5, and the inverse demand curve for taxi cab rides is P = 20 - Q in a competitive market. Subsequently, only 10 taxi cabs are allowed in the market. After the market adjusts to the restricted supply
there will be a decrease in consumer surplus.
In the long run, competitive firms MUST be profit maximizers because if they do not maximize profits,
they will not survive.
Producer surplus equals
total revenue minus total variable cost. total revenue minus the sum of all marginal cost. profit plus fixed cost
If activists successfully lobbied government to force firms to produce more output than they normally would in a perfectly competitive market
total surplus in the market would decline
Economists claim that measuring society's welfare as CS + PS
treats the gains to consumers and producers equally
The above figure shows supply and demand curves for milk. In an effort to help farms, the government passes a law that establishes a $3 per gallon price support, but allows farmers to decide how much milk to produce. The government then provides a deficiency payment to guarantee that the farmers receive $3 per gallon. The required deficiency payment equals
b + c + f + g + h + i + j.
The above figure shows supply and demand curves for milk. If the government passes a $2 per gallon specific tax, the loss in consumer surplus will equal
b + f.
The above figure shows supply and demand curves for milk. In an effort to help farmers, the government passes a law that establishes a $3 per gallon price support. As a result, consumer surplus falls by
b + f.
Long-run economic profit does not exist for fixed factors like land because
bidding drives up the price of the factor until no economic profit exists

both her utility and her consumer surplus will increase

c - f

cause consumer surplus to decline among smokers, but the relative impact cannot be determined from the given information
The services of real estate brokers are provided in a competitive market. If the state Board of Realtors enacts several requirements that limit the number of real estate brokers, then social welfare will most likely
decrease, although producers are made better off
Sarah and David both have linear demand curves for lemonade. Sarah's demand curve for lemonade intersects David's demand curve at a price of 50 cents per glass. Sarah's demand curve is more inelastic than David's. A change in the price of lemonade from 50 cents to 25 cents per glass will
increase David's consumer surplus more than Sarah's
The above figure shows supply and demand curves for milk. In an effort to help farms, the government passes a law that establishes a $3 per gallon price support, but allows farmers to decide how much milk to produce. The government then provides a deficiency payment to guarantee that the farmers receive $3 per gallon. The welfare loss of this price support is

If a market produces a level of output that exceeds the competitive equilibrium output, then
marginal cost will exceed price.
Consumers seek to
maximize expected consumer surplus
Suppose consumers of cigarettes can be classified into two groups: heavy users and light users. Heavy users purchase more cigarettes and are less sensitive to price changes relative to light users. To determine whether a heavy user suffers a greater loss of consumer surplus than a light user does when the price of cigarettes increases, one would need to know
no additional information
Mister Jones was selling his house. The asking price was $220,000, and Jones decided he would take no less than $200,000. After some negotiation, Mister Smith purchased the house for $205,000. Smith's consumer surplus is
not able to be calculated from the information given

They value producer surplus more than consumer surplus.
You enter a store and buy a bottle of soda. Do you usually receive consumer surplus?
Yes, because you wouldn't buy the soda if your willingness to pay would be less than the price.
Does a competitive long-run equilibrium require cost-minimization?
Yes, if firms fail to be as efficient as their competitors, they are driven out of the market.

all gift are money. everybody gets exactly what they want. nobody can be made better off by returning the gift and purchasing a different one.
The total welfare associated with a market that includes a government sales tax equals
consumer surplus plus producer surplus plus government tax revenue.
The above figure shows supply and demand curves for apartment units in a large city. If the city government passes a law that establishes $350 per month as the legal maximum rent, deadweight loss occurs because
consumers place a greater value on the last apartment unit than the cost to supply it
Consumers often purchase products that, afterward, they regret purchasing. This can be explained by
consumers trying products to determine if their consumer surplus increases

decrease consumer surplus in the market
The above figure shows supply and demand curves for apartment units in a large city. If the city government passes a law that establishes $350 per month as the legal maximum rent, producer surplus
decreases.
In economics, welfare analysis is useful to
determine who gains and who loses in a particular policy option.
Assume a consumer has a horizontal demand curve for a product. His consumer surplus from buying the product
equals zero

The above figure shows supply and demand curves for apartment units in a large city. If the city government passes a law that establishes $350 per month as the legal maximum rent, the loss in social welfare equals
f + g.

fall by $84
Survivability in a perfectly competitive world requires that
firms maximize profit
The difference between producer surplus and profit is always the associated with
fixed costs
If a firm enjoys producer surplus in perfectly competitive Market A of $1000 and would enjoy producer surplus in perfectly competitive Market B of $1200, the firm would consider moving to Market B if
fixed costs in Market B are less than the fixed costs in Market A plus $200
If a market produces a level of output below the competitive equilibrium, then
social welfare is not maximized.
If in a market the last unit of output was sold at a price higher than marginal cost,
social welfare is not maximized.
Advocates of steel tariffs to protect U.S. steel firms realize that when imposing such tariffs, the gains of firms are outweighed by the losses to consumers.. This implies that
such advocates value producer surplus more than consumer surplus
The deadweight loss associated with output less than the competitive level can be determined by
summing the change in the total consumer and producer surplus from moving from the competitive level of output to less output.
Producer surplus is equal to
the difference between price and marginal cost for all units sold
If a firm is in a perfectly competitive world but decides to charge a higher price than its competitors,
the firm's profits will be zero or negative, and the firm will fail in the long run.
Suppose when a market has four firms, average economic profit is $1,000 per month. When the market has five firms, the average economic profit is -$50 per month. This suggests that
the long-run equilibrium number of firms is between four and five
