If demand increases (decreases) and supply is unchanged, then it leads to a higher (lower) equilibrium price and quantity. If supply increases (decreases) and demand is unchanged, then it leads to a lower (higher) equilibrium price and higher (lower) quantity.
Hereof, what happens to the demand curve when the price goes up?
Decreases in demand. Conversely, demand can decrease and cause a shift to the left of the demand curve for a number of reasons, including a fall in income, assuming a good is a normal good, a fall in the price of a substitute and a rise in the price of a complement.
Why does price decrease when demand increases?
In microeconomics, the law of demand states that, "conditional on all else being equal, as the price of a good increases (↑), quantity demanded decreases (↓); conversely, as the price of a good decreases (↓), quantity demanded increases (↑)".
What will happen when the price of a good increases?
According to the law of supply, if the price of a good or service increases: Quantity supplied will increase. If two goods are complements, an increase in the price of one good will cause a decrease in the demand for the other.
