Maximizing the Gains from Trade

Total Surplus as a Price-Independent Sum of Consumer and Producer Surplus

Calculating Gains from a Transaction

A student is willing to pay a maximum of $80 for a used calculator. The owner of the calculator is willing to sell it for any price of $30 or more. They eventually agree on a price of $50. Given this transaction, what is the total joint surplus created for both individuals combined?

A buyer is willing to pay up to $100 for a concert ticket, and a seller is willing to accept any price of $60 or more. If they successfully negotiate a price and complete the transaction, how does the final agreed-upon price affect the total joint surplus created?

In a voluntary transaction between one buyer and one seller, if the final agreed-upon price is set closer to the buyer's maximum willingness to pay, the total joint surplus generated by the transaction is larger than if the price were set closer to the seller's minimum willingness to accept.

An economic agent is trying to facilitate a single trade to create the maximum possible economic value. The agent has identified four potential pairings of a buyer and a seller for a specific unique good. Which of the following pairings should be matched to generate the largest total gain from the transaction?

Distribution of Gains in a Transaction

Consider the following transaction: A buyer, who is willing to pay up to $150 for a bicycle, purchases it from a seller, who would have accepted a minimum of $90. They agree on a final price of $110. Match each economic concept to its correct monetary value based on this transaction.
