Note: This is post #22 in a weekly video series on basic microeconomics.
Prices are signals that indicate to suppliers how much is being demanded. So what happens when the government puts a cap on the price that can be charged for a product or service? Two effects are shortages and lower quality. In this video by Marginal Revolution University, economist Alex Tabarrok explains why this happens.
(If you find the pace of the videos too slow, I’d recommend watching them at 1.5 to 2 times the speed. You can adjust the speed at which the video plays by clicking on “Settings” (the gear symbol) and changing “Speed” from normal to 1.25, 1.5 or 2.)
