which of these lists only factors that would cause an increase in the supply of an item? a decrease in input prices; an innovation in production technology; a fall in the price of a substitute - in - production a rise in the price of a substitute - in - production; an increase in the price of a complement - in - production; an expectation that the price of the item will increase in the future a decrease in the number of sellers in the market; a rise in the price of a complement - in - production; an innovation in production technology an increase in input prices; a decrease in the number of sellers in the market; an increase in the price of a substitute - in - production
Answer
Brief Explanations:
A decrease in input prices lowers production costs, allowing producers to supply more. Innovation in production technology increases efficiency and output. A fall in the price of a substitute - in - production makes the production of the item more attractive, increasing its supply. Other options have factors that would either decrease supply (like an increase in input prices or a decrease in the number of sellers) or have ambiguous or opposite effects on supply.
Answer:
a decrease in input prices; an innovation in production technology; a fall in the price of a substitute - in - production
