Consider a market where 500 units of a good are being bought and sold. A new government policy is implemented that causes the market price to fall, but the total number of units exchanged in the market remains unchanged at 500. What is the most likely impact of this price decrease on consumer surplus, producer surplus, and total surplus?

Evaluating Policy Arguments on Market Surplus

A technological innovation allows producers to lower their prices. If this change results in the exact same number of units being sold as before the innovation, the total surplus in the market will increase.

The Role of Price in Total Surplus Calculation

Evaluating a Policy Statement on Market Surplus

A market is initially in a state where 100 units of a good are exchanged. For each independent scenario described below, match it with the correct resulting impact on consumer surplus, producer surplus, and total surplus.

Consider a market for a specific good. In Scenario X, a government intervention results in 50 units of the good being exchanged at a price of $15 per unit. In Scenario Y, a different government intervention in the same market results in 50 units of the good being exchanged at a price of $25 per unit. Assuming the underlying willingness to pay for buyers and willingness to accept for sellers for these 50 units are the same in both scenarios, how does the total economic gain (the sum of benefits to all buyers and sellers) in Scenario X compare to that in Scenario Y?

A single unit of a good is exchanged in a market. The buyer's willingness to pay for the unit is $80, and the seller's cost to produce it is $30. The transaction occurs at a price of $60. Which of the following expressions correctly represents the calculation of the total surplus generated from this transaction by summing its component parts?

While a change in the market price of a good will redistribute the gains from trade between buyers and sellers, it does not alter the total surplus as long as the ________ of goods exchanged remains constant.
