Question 20

Movement along the supply curve up and to the right

As the price of milk increases, producers are typically incentivized to supply more milk, resulting in a movement along the supply curve up and to the right. This reflects the law of supply, where higher prices lead to an increase in quantity supplied.

A) Movement along the supply curve up and to the right

This option is correct because it accurately describes how an increase in price leads to an increase in the quantity of milk supplied. Producers respond to higher prices by offering more of the product, which is represented graphically as a movement along the existing supply curve.

B) Shift in the supply curve to the right

This option is incorrect because a shift in the supply curve to the right would indicate an increase in supply due to factors other than price, such as technological advancements or a decrease in production costs. An increase in price does not cause this shift; it results in movement along the curve instead.

C) Shift in the supply curve to the left

This option is also incorrect. A leftward shift in the supply curve indicates a decrease in supply, which can occur due to rising production costs or other negative factors. An increase in price does not lead to this outcome; rather, it encourages more supply along the existing curve.

D) Movement along the supply curve down and to the left

This option is incorrect as it suggests that an increase in price would lead to a decrease in quantity supplied, which contradicts the basic principles of supply. An upward movement along the supply curve occurs with price increases, not downward movement.

Conclusion

The correct outcome of an increase in the price of milk is a movement along the supply curve up and to the right, reflecting the law of supply. All other options fail to accurately represent the relationship between price and quantity supplied, either suggesting incorrect shifts or movements contrary to economic principles.
