Question

19 multiple choice 1 point refer to the figure above, which shows three supply curves for corn. which of the following would cause the supply of corn to shift from s₁ to s₂? a decrease in consumer incomes, assuming corn is a normal good an increase in the price of fertilizer the development of a more effective insecticide against corn rootworm a change in consumer tastes away from cornbread 20 multiple choice 1 point

Explanation:

A shift from $S_1$ to $S_2$ is a rightward shift of the supply curve, meaning the quantity supplied of corn increases at every price.

• A decrease in consumer incomes (for a normal good) and a change in tastes away from cornbread affect demand, not supply, so they are incorrect.
• An increase in fertilizer price raises production costs, which would shift supply leftward (to $S_3$), not rightward.
• A more effective insecticide reduces crop loss and lowers production costs, allowing farmers to supply more corn at each price, shifting supply rightward to $S_2$.

Answer:

the development of a more effective insecticide against corn rootworm
