Two friends, Andrew and Xolali, are arguing about the Long Run Average Cost (LRAC) curve and Short Run Average Cost (SAC) curves. Andrew is of the view that a firm's Long Run Average Cost (LRAC) curve touches the minimum part of every Short Run Average Cost (SRAC) curve. But Xolali argues that it is the minimum point of the Long Run Average Cost (LRAC) curve that touches the minimum part of only one Short Run Average Cost (SRAC) curve. Which of the two friends do you support, and why?
