4. Producer surplus for an individual and a market
Suppose the market for gourmet cupcakes is perfectly competitive, so sellers take the market price as given. Lorenzo manages a bakery that offers
gourmet cupcakes for sale. The following graph plots Lorenzo's weekly supply curve (orange line). Point A represents a point along his supply curve.
The price of gourmet cupcakes is $2.50 per cupcake, which is given by the black horizontal line.

QUANTITY (Cupcakes)
Using the previous graph, you can determine that Lorenzo is willing to supply his 2nd weekly cupcake for $
. Since he receives $2.50 per
cupcake, the producer surplus earned from supplying the 2nd cupcake is $
.
Suppose the price of gourmet cupcakes were to rise to $3.00 per cupcake. At this higher price, Lorenzo would receive a producer surplus of
$
from the 2nd cupcake he sells.
The following graph plots the weekly market supply curve (orange line) for gourmet cupcakes in a hypothetical small economy.
Use the purple point (diamond symbol) to shade the area representing producer surplus (PS) when the price (P) of gourmet cupcakes is $2.50 per
cupcake. Then, use the green point (triangle symbol) to shade the area representing additional producer surplus when the price rises to $3.00 per
cupcake.
