  • Supply Curve. Why is there a direct relationship between price and quantity supplied?
    Transcript: 1 In the supply curve, we want to know the relationship between price and quantity supplied. Let’s make it really simple by keeping everything else constant. That means ceteris paribus, 2 Great, only price and quantity left. As usual, we put the price on the vertical axis and quantity on the horizontal axis. JINGLE As producers, we love profits like bees love honey.

But at $4, woah, higher price, Let’s supply more cakes. (20) Connect the dots. Tada, the supply curve! Note-- it’s upward sloping. When price increases, quantity supplied increases.

In other words, the supply curve has a positive gradient. The law of supply states that there is a direct relationship between price and quantity supplied.
