What variables other than price and advertising are likely to affect the quantity demanded of a product?

Usually quality is demanded of a product, not quantity.

If you are referring to the Demand Curve of "Supply and Demand", product quality, product reviews (now easily found on the internet), and "word of mouth" affect the number sold, as do price and advertising.

A decrease in aggregate supply means:

A. Both the real domestic output and the price level would decrease
B. The real domestic output would increase and rises in the price level would become smaller
C. The real domestic output would decrease and the price level would rise
D. Both the real domestic output and rises in the price level would become greater

When determining the factors that affect the quantity demanded of a product, it is important to consider that consumer behavior is influenced by numerous variables. In addition to price and advertising, here are some other factors that are likely to impact the quantity demanded of a product:

1. Consumer Income: Consumer income plays a crucial role in determining how much consumers are willing and able to spend on a product. Generally, as income increases, the quantity demanded for most goods and services tends to increase as well.

2. Consumer Preferences and Tastes: Consumer preferences and tastes refer to the subjective preferences individuals have for various products. Factors such as culture, social norms, personal experiences, and individual tastes influence consumers' choices, which in turn impact the quantity demanded of a product.

3. Price of Substitute Goods: Substitute goods are those that can be used in place of one another. A change in the price of substitute goods can affect the demand for a particular product. For example, if the price of one brand of coffee increases significantly, consumers may switch to a different brand, leading to a decrease in the quantity demanded for the original brand.

4. Price of Complementary Goods: Complementary goods are products that are typically used together. A change in the price of a complementary good can affect the demand for the primary product. For instance, if the price of video game consoles decreases, it can lead to an increase in the quantity demanded for video games as more people buy consoles and need games to play.

5. Consumer Expectations: Consumers often base their purchasing decisions on their future expectations. If consumers anticipate that the price of a product will increase in the future, they may buy more now, increasing the quantity demanded. Conversely, if they expect a decrease in price, they may delay making a purchase, resulting in a decrease in the quantity demanded.

6. Demographic Factors: Factors such as age, gender, education, and household size can influence consumer preferences and purchasing decisions. For example, a product targeted towards young adults may have higher demand among that age group, which would impact its quantity demanded.

These are just a few examples of factors that can affect the quantity demanded of a product. It is essential to consider all relevant factors when analyzing consumer behavior and demand.
