The Above statement is TRUE .
because there are jumps and kinks , we can not draw a straight line through scatter plot . It means we can not described linear model

1. Answer four of the following. In each case answer True, False or Uncertain and explain your answer. Limit each answer to one page (a) A firm has a technology that relies on only one input (call it x). The output of the firm (call it y) increases as you increase x but at a diminishing rate. Based only on the information provided then y-x would be a valid representation of this firms production function (b) Consider the system of...
True/False/Uncertain. For each question, answer “True” or “False” or “Uncertain” and explain your answer. (1) In any game between two firms that is repeated only once, the outcome will be perfect competition (P=MC).
