A decrease in demand is represented by a group of answer choices movement along the demand curve to the right. shift of the demand curve to the right. shift of the demand curve to the left. shift in the supply curve.
The Correct Answer and Explanation is:
The correct answer is: shift of the demand curve to the left.
A decrease in demand refers to a situation where, at every price level, the quantity demanded for a good or service decreases. This change is represented by a shift of the demand curve to the left.
Explanation:
In economics, the law of demand states that, ceteris paribus (with all other factors remaining constant), as the price of a good or service increases, the quantity demanded decreases, and vice versa. This relationship is reflected in a downward-sloping demand curve. However, a decrease in demand does not result from a change in price alone; rather, it is caused by other factors, often referred to as the determinants of demand. These factors include:
- Income: If consumers experience a decrease in income, they may buy less of a good or service, even if its price stays the same.
- Tastes and Preferences: If a good or service falls out of favor with consumers, the demand for it will decrease.
- Prices of Related Goods: A decrease in the price of a substitute good (such as coffee for tea) can reduce the demand for the original good. Conversely, a decrease in the price of a complementary good (such as printers for computers) could also decrease demand if the price change impacts the overall spending on complementary products.
- Expectations of Future Prices: If consumers expect prices to fall in the future, they might reduce their current demand in anticipation of lower prices.
- Population Size: A decrease in the population, or a decrease in the number of consumers in a market, can lead to a decrease in demand.
A decrease in demand means that consumers are less willing or able to purchase the same quantity of a good at each price point, resulting in the entire demand curve shifting to the left. This is different from a movement along the demand curve, which occurs when a price change leads to a change in the quantity demanded, but not a shift in demand itself.
Thus, the correct representation of a decrease in demand is a leftward shift of the demand curve, showing that at every price level, consumers are now demanding a lower quantity of the good.
