Rowan and Vale produce 11 reconciliations and 3 forecasts before specialization, and 12 reconciliations and 4 forecasts after specializing by comparative advantage. Rowan's cost of a reconciliation is 0.5 forecast; Vale's is 1. A proposed term is 0.75 forecast per reconciliation. Which conclusion is sound?

Choose the best answer. a Specialization raises the modeled bundle from 11 reconciliations and 3 forecasts to 12 and 4, and 0.75 forecast per reconciliation lies between costs of 0.5 and 1; realized net gains and their distribution still require contract, cost, quality, risk, and bargaining evidence. b Because both modeled totals increase, every worker, owner, client, and creditor must gain by the same amount. c Any positive trade rate works because specialization automatically guarantees mutually beneficial exchange.

Answer: a

Choice a. The model adds one unit of each output and places 0.75 strictly between the 0.5 and 1 opportunity costs. It establishes neither realized net benefit nor equal distribution.
