The price rise.
With respect to classical economics (all things being equal) there are two possible situations which represent price increases:
Prices normally increase as demand increases and decrease as demand decreases.
In the short run nothing happens to price
It goes up
What ever the demand is it's scarce
price rises and quantity increases
The price for the good increases
Prices normally increase as demand increases and decrease as demand decreases.
In the short run nothing happens to price
Equilibrium price increases
It goes up
it increases
What ever the demand is it's scarce
price rises and quantity increases
Quantity of demand increases and supplies decreases.
it always increases
The first basic law of supply and demand is: If demand increases and supply remains unchanged, a shortage occurs, leading to a higher equilibrium price. So the price goes up.
The prices increases, because the demand is higher for the product, since there is less of it.
