Question

Quizplus · Accepted Answer

An increase in the price of swordfish would not shift the supply curve, as the price is already included on the vertical axis of the supply curve. A shift in supply is caused by a change in a non-price determinant, such as technology or input costs. A reduction in available fishing boats (A) would shift the supply curve to the left, as there would be fewer swordfish available. Unusually stormy weather during fishing season (B) could also shift the supply curve to the left, as it would make it more difficult to catch swordfish. The development of innovative new fishing equipment that makes it easier to catch swordfish (C) would shift the supply curve to the right, as it would increase the number of swordfish available.
