Final answer:
The non-price determinants of demand from the options provided are prices of complementary goods and prices of substitute goods. These factors can shift the demand curve without a change in the price of the good itself. The correct options that are non-price determinants of demand are (a) prices of complementary goods and (c) prices of substitute goods.
Step-by-step explanation:
The non-price determinants of demand refer to factors that can shift the demand curve for goods and services, resulting in a different quantity being demanded at any given price, without changes in the price of the good itself. From the options provided, the non-price determinants of demand include:
• Prices of complementary goods
• Prices of substitute goods
• Changes in Expectations about Future Prices or Other Factors that Affect Demand
The correct options that are non-price determinants of demand are (a) prices of complementary goods and (c) prices of substitute goods. A change in the price of complementary or substitute goods affects the demand for a related good. For instance, an increase in the price of golf clubs (a complement) will result in a decrease in the demand for golf balls. Similarly, changes in expectations regarding future prices can lead to a shift in demand.
