This documentary tells the story of Lilly Ledbetter, whose fight for equal pay for equal work eventually involved all three branches of government. Her U.S. Supreme Court case, Ledbetter v. Goodyear Tire and Rubber Co., turned on the interpretation of the 180-day statute of limitations for filing a discrimination complaint under Title VII of the Civil Rights Act of 1964. After losing at the Supreme Court, Ledbetter urged Congress to start the 180-day clock for filing a complaint on the date an employee learned of the discrimination. The result was the Lilly Ledbetter Fair Pay Act of 2009.

In this video we illustrate and explain the differences between a change in the quantity demanded for a good (which causes a movement along a demand curve) and the change in a good's demand (which causes the entire demand curve to shift).
A demand shifter is a change that shifts the demand curve for a product. One of the demand shifters is buyers' expectations. If a buyer expects the price of a good to go down in the future, they hold off buying it today, so the demand for that good today decreases. On the other hand, if a buyer expects the price to go up in the future, the demand for the good today increases. Explore the role of buyers' expectations as a determinant of demand in this video.

A common error new economic students make is confusing changes in supply with changes in quantity supplied. A change in quantity supplied is a movement along the supply curve in response to a change in price. A change in supply is a shift of the entire supply curve in response to something besides price.
