I'm reminded of what happened to carpenters, tree-removal firms, generator retailers, and others in North Carolina after Hurricane Fran, as then–Attorney General Mike Easley took to the airwaves repeatedly warning about price gouging.
The anti–price gouging law is a government price ceiling that tends to create shortages in necessities by keeping their prices during a disaster "fair." The governor, by relaxing certain regulations, is able to lower the regulatory costs of providing those necessities, which helps offset the bad effects of the anti–price gouging law.
Not long ago I wrote about how tariffs are like minimum-wage laws: they're both policies based in bad economics, well outside the mainstream of economic thought. They're also (and for the same reason) especially bad for the poor.
