Which of the following is a factor that can affect price determination?

• A. Costs of inputs
• B. Changes in technology
• C. Changes in prices of other goods
• D. All of the above

Answer: (D)

The price that emerges in a market comes from the interaction of supply and demand, and anything that shifts either side can change the equilibrium price. Costs of inputs affect price by altering supply: when production costs rise, producers can’t sell as much at each price, so the supply curve shifts left and the market tends toward a higher price to clear fewer sales. Changes in technology affect price through efficiency gains: better technology lowers production costs, so supply shifts right, usually leading to a lower price and more output if demand stays the same. Changes in prices of other goods influence price as well because they can change both producer decisions and consumer choices. If the price of a substitute in production rises, producers may switch to that higher-value good, reducing supply of the current good and pushing its price up. Similarly, shifts in the prices of related goods can affect demand, altering the equilibrium price. Since each of these can move the balance of supply or demand, all of them can influence price determination.
