The demand curve can only shift in one direction. True False
The correct answer and explanation is:
The correct answer is False.
The demand curve can shift in both directions depending on various factors that influence consumer behavior. A demand curve represents the relationship between the price of a good or service and the quantity demanded. It typically slopes downwards from left to right, meaning that as the price of a good decreases, the quantity demanded increases.
However, the demand curve is not fixed in one position; it can shift due to changes in external factors. These factors are often referred to as determinants of demand and can cause the entire demand curve to shift either to the right (increase in demand) or to the left (decrease in demand). Some of the key factors that affect demand include:
- Income: When consumers’ income increases, they generally demand more goods and services, shifting the demand curve to the right. Conversely, a decrease in income reduces demand, shifting the curve to the left.
- Tastes and preferences: If consumer preferences change in favor of a product, the demand curve shifts to the right. If preferences change against a product, the demand curve shifts to the left.
- Prices of related goods: If the price of a substitute good (e.g., tea for coffee) increases, demand for the original good may rise, shifting the demand curve to the right. If the price of a complementary good (e.g., printers for computers) increases, demand for the original good may decrease, shifting the demand curve to the left.
- Expectations of future prices: If consumers expect prices to rise in the future, they may buy more now, increasing demand and shifting the curve to the right. If they expect prices to fall, demand may decrease, shifting the curve to the left.
- Population changes: An increase in the population generally leads to a higher demand for goods and services, shifting the demand curve to the right.
Thus, the demand curve can shift in both directions, depending on the changes in these factors.
