B. is a particular set of institutional arrangements and a coordinating mechanism used to respond to the economizing problem. C. requires some sort of centralized authority (such as government) to coordinate economic activity. D. is a plan or scheme that allows a firm to make money at some other firm's expense. 11.

B. price elasticity of demand will not change as price is lowered. C. demand will become less price elastic. D. the elasticity of supply will increase. 16. Which of the following statements concerning the relationships between total product (TP), average product (AP), and marginal product (MP) is not correct? A. AP continues to rise so long as TP is rising. B. AP reaches a maximum before TP reaches a maximum. C. TP reaches a maximum when the MP of the variable input becomes zero
