Question 1 Report
The diagram in Fig. 1 shows how installing robots changes the supply curve for a firm producing metal lunch boxes. The robots reduce the number of workers needed for each box.
(a) Which curve, S1 or S2, shows supply after the robots are installed? Explain your answer. [2]
(a) Supply after the robots are installed is shown by S2 [1]. Robots reduce the number of workers needed per lunch box, lowering labour costs. Lower costs allow the firm to supply more lunch boxes at every given price, so supply increases [1]. On the diagram, this is the rightward shift from S1 to S2, not simply a movement along one supply curve.
