<p>Yes, when the demand curve <em>shifts</em> to the right (all else equal), the equilibrium market price rises to account for the fact that consumers are now willing to pay more. The increase in price is the mechanism by which excess demand at the initial price is cleared:</p>

<p>There is no contradiction here in the supply-and-demand model. Note that movements <em>along</em> the demand curve can only occur when we are away from a market equilibrium. These price movements are traced out by shifts of the supply curve and they continue until the new market equilibrium is reached.</p>

<p>The demand function is dependent on quantity, and the result of which will be the price. The utility function and budget constraints are the same </p>

When demand increases why does the price decrease but equilibrium price increase?

On a demand curve when the demand increases the price will decrease. However on a demand and supply graph, when the demand shifts to the right, the price will increase. I understand why, but then what is the point of analyzing a demand curve, if it contradicts the market equilibrium graph?

I am sorry if this is a stupid question. It has only been a month since I have started economics in high school.

> On a demand curve when the demand increases the price will decrease.

You actually mean "along the demand curve, a decrease in price will increase quantity demanded, all else equal". This is the [law of demand](https://en.wikipedia.org/wiki/Law_of_demand), and it holds for ordinary ("non-Giffen/Veblen") goods that have downward-sloping demand curves. There is *no shift* of the demand schedule in this scenario:

Yes, when the demand curve *shifts* to the right (all else equal), the equilibrium market price rises to account for the fact that consumers are now willing to pay more. The increase in price is the mechanism by which excess demand at the initial price is cleared:
