Q&A

What is the difference between demand and quantity demanded?

Demand refers to the overall buying behavior of consumers for all possible prices, while quantity demanded is the quantity of a good or service that consumers are willing and able to buy at a specific price.

How are changes in quantity demanded represented?

Changes in quantity demanded are shown as a movement along the demand curve.

What causes changes in demand?

Changes in demand occur when factors such as income, preferences, and expectations influence consumers' purchasing decisions.

What is the ceteris paribus assumption?

Ceteris paribus is a Latin phrase meaning 'all other things held equal.' Economists use this assumption to focus on the impact of price changes on consumer behavior while holding other factors constant.

How do shifts in the demand curve affect price and quantity demanded?

If demand for a product increases, the demand curve shifts to the right, resulting in new combinations of prices and quantity demanded. Conversely, if demand decreases, the curve shifts to the left.
