Coffee Market Supply and Demand Graph

Bay Roasters Coffee Market — Supply and Demand

This supply-and-demand example models the weekly market for roasted coffee beans sold to Bay Roasters. The vertical axis is price per bag and the horizontal axis is hundreds of bags sold each week. The upward supply curve represents higher marginal costs as the roaster prepares more bags. The downward demand curve represents buyers purchasing fewer bags as prices rise. Their intersection identifies the model's equilibrium price and quantity. The shaded areas make the gains to buyers and sellers visible. It is a teaching model, not a forecast: actual prices also reflect contracts, inventory, quality grades and competing suppliers and seasonal demand.

자주 묻는 질문

What does the intersection mean?

It is the equilibrium in this model, where quantity supplied equals quantity demanded.

Why does supply slope upward?

Producing additional units often raises marginal cost, so sellers require a higher price.

Why does demand slope downward?

Buyers generally purchase fewer units when the price rises, holding other factors constant.
