The First Theorem of Welfare Economics can be expressed as A) the competitive equilibrium results only when no transactions costs exist. B) the competitive equilibrium does not involve reallocation of endowments. C) any efficient allocations can be achieved by competition. D) the competitive equilibrium is efficient. ANSWER D
When two people trade their initial endowments to a point on the contract curve, only the level of the endowments will determine the new allocation. Indicate whether the statement is true or false ANSWER False. The respective bargaining abilities will also play a role in determining the final allocation.
