Dwight corners the market on Princess Unicorn dolls! This is a good opportunity to discuss the relationship between expected future prices and changes in demand. Dwight knew that the demand for these dolls would increase as Christmas drew closer. Advanced students should be able to draw a supply and demand graph for this market and see that in the very short run the supply of this good is perfectly inelastic in the Scranton area. This makes the profit opportunity for Dwight even greater.
