When I was growing up I had a buddy—let’s call him “Bob”—who was constantly asking, “What happens if we do . . . ?” Bob’s curiosity, however, only led him to wonder about foolish actions. He never pondered, for example, what would happen if we all volunteered at the senior citizens center. Instead, his thinking ran more along the lines of what would happen if we jumped off the senior citizens center.
The reaction of me and the rest of my friends was always, “Let’s find out!” But we were more prudent than Bob (or maybe just more cowardly) so we’d encourage him to try whatever reckless idea he had in mind so we could learn from his experience. We learned, for instance, that if jump off the 3-story senior citizens center, a stack of cardboard boxes will not be enough to sufficiently break your fall.
Bob’s shenanigans would daily provide for us what social scientists would call a “natural experiment.” A natural experiment is a study of the effect of an independent variable, which has not been planned or manipulated by the researchers, on a dependent variable. (The word ‘natural’ in the term natural experiment therefore refers to an event that is not planned by the researchers.)
The city of Seattle is about to pull a Bob, by foolishly raising the minimum wage to $15 per hour. The effect on the citizens of Seattle will be almost entirely harmful. But it will provide a natural experiment on the effect of raising the minimum wage laws that the rest of American can learn from. Anyone who isn’t already convinced that increasing the minimum wage has a detrimental impact on employment and harm minority workers will, in a few years, have solid proof. We will all be able to look to Seattle to see the difference between good, albeit naive, intentions and sound economic policy.
Here are some of the effects I predict the policy will have in the next three years:
