As taught by Thomas Sowell in his book "Basic Economics":
If the prices of hotel rooms remain what they have been in normal times, those who happen to arrive at the hotels first will take all the rooms, and those who arrive later will either have to sleep outdoors, or in damaged homes that may offer little protection from the weather, or else leave the local area and thus leave their homes vulnerable to looters. But, if hotel prices rise sharply, people will have incentives to ration themselves. A couple with children, who might rent one hotel room for themselves and another for their children, when the prices are kept down to their normal level, will have incentives to rent just one room for the whole family when the rents are abnormally high—that is, when there is “price gouging.”
Are there any countries or states that have fully embraced this economic principle and welcome/expect price gouging in case of natural disasters? Or at the very least countries where it's perhaps considered impolite but where the authorities don't interfere with sellers setting the prices as high as they want during times of need?
