Which of the following is NOT a non-price determinant of supply?

The correct answer, which identifies something that is NOT a non-price determinant of supply, is the price of goods. Non-price determinants of supply refer to factors that can lead to a shift in the supply curve, but these factors do not involve the actual price of the goods being supplied. Instead, they focus on external influences that affect production decisions.

Costs of production, government taxes and subsidies, and the state of technology all play significant roles in shaping supply. For instance, if the cost of production increases, producers may supply less at any given price, leading to a leftward shift in the supply curve. Similarly, government taxes can raise production costs, whereas subsidies can lower them, thereby influencing the quantity supplied. The state of technology can also enhance production efficiency, enabling suppliers to produce more at lower costs.

In contrast, the price of goods directly affects the quantity supplied, which is reflected in movements along the supply curve rather than shifts of the curve itself. If the price of a good changes, it generally results in a change in the quantity supplied, rather than a change in the overall supply conditions. Therefore, the price of goods is not considered a non-price determinant of supply.
