TranscriptNotes

0:00All right. Last week we finished with the concept of consumer surplus. Today we build on that with producer surplus.
0:11Producer surplus is the difference between what a producer would accept for a good and what they actually receive.
0:23Together, consumer plus producer surplus gives us total welfare in a market before we introduce taxes or price controls.
0:35Now, why do we care about this concept practically? Because it lets us evaluate whether policy makes a market better or worse off.
0:47Consider a per-unit tax. It shifts the supply curve upward by the tax amount, and both surpluses shrink.
0:58The gap that appears between what buyers pay and what sellers receive is what we call deadweight loss.
1:08Please open the workbook to page thirty-one, and let us work through a numerical example together.
