Eat Your Vegetables: City Council Considers A Well-Disguised Sin Tax


The Oklahoma City Council is considering a well-disguised sin tax. They call it a Healthy Neighborhood Zoning Overlay, but the effect is the same. It limits new dollar stores in the specified neighborhood. The ostensible goal is to create a welcoming environment for grocery stores selling fresh meat and produce. But it accomplishes this goal by giving existing dollar stores a monopoly, which will raise prices, and punish residents for shopping at the purveyors of (allegedly nothing but) junk food, instead of subsisting on fresh, organic kale smoothies like good little citizens.

Why would the Council intentionally restrict the supply of stores where many of their residents buy basic household goods and food? Several possibilities present themselves, though none are sound. 

A fundamental misunderstanding of the laws of supply and demand.
Economists call the current state of the neighborhood a contestable market: dollar stores choose low prices because the mere potential of competition keeps them honest. If they charged monopoly prices, a competitor, enticed by the potential for abnormally high profits, would enter the neighborhood, causing both sides to lower prices again. 

The proposed Zoning Overlay, however, would end this deterrent to price-gouging. If new stores are too difficult to open, or prohibited from selecting the best locations, what is to stop the existing stores (all of whom are owned by the same parent company) from raising their prices? In fact, even stores who were vigorously competing would likely raise their prices in unison with each other (effecting monopoly pricing without an illegal conspiracy), once they were protected by this type of Zoning Overlay.

A misunderstanding of basic nutrition.
The dollar stores in question offer at least some frozen or canned vegetables. While many prefer the taste of fresh produce, there is substantial evidence that frozen and canned vegetables are just as healthy as fresh. Is the problem the availability of nutrients? Or is the Council trying to bully residents into eating the “right way?

A desire to elevate a special class of merchants.
This seems like an unintended consequence, not the design of the program. But federal antitrust laws carve out an exception for state and local laws. So if someone wanted to favor a particular kind of store, zoning laws can become a legal way to cheat the system. The state gives new car dealers just this sort of protection, explicitly stating that it does so to protect them from competition, in order to make sure they stay viable. Existing dollar stores may even realize the boon they are about to receive from the city council. 

Using public policy to punish, and thereby reduce, specific, undesirable behavior. 
This happens all the time. We call it a sin tax - think cigarettes, alcohol or gambling. Are we comfortable labeling junk food a “sin”? A traditional sin tax directs the proceeds to the public coffers, for some worthy project to offset the sin. Here, the proceeds of the “tax” will go to the purveyors of the so-called sin. Is that a desirable policy? 

The Council wants to impose its dietary norms on the public. It can’t force people to eat healthy. A direct tax on junk food, much less healthy nonperishables, would be wildly unpopular. So it found a clever workaround to punish residents for patronizing unhealthy dollar stores over virtuous grocers. 

The proposed zoning overlay is a relatively small geographic area. Of course, the initial cause for concern was the difficulty residents without cars have getting groceries. These are the people who will still be stuck paying monopoly prices at dollar stores, while residents with cars go outside the overlay to do their shopping. The Overlay is likely to do the most harm to the very people it is supposed to help. But don't worry, residents of 73111, the Overlay is not permanent. As soon as you clean up your act, the city promises to stop punishing you.

The Problem of Diffuse Costs and Concentrated Benefits

Do you ever find yourself observing a seemingly illogical government program , spending decision, or other strange practice and ask “how is it that no one has fixed that?” If you are like me, you encounter this phenomenon regularly. This often takes the form of a curious headline (Save Federal Funding for the Cowboy Poets!) that most people see and can’t believe is real. I would like to suggest that this phenomenon often results from the problem of diffuse costs and concentrated benefits. To understand this concept, consider a hypothetical law that assessed a $1 tax on everyone in the United States with the proceeds to be given to one individual for unrestricted use as he sees fit. The people harmed by such a law—the individual taxpayers—will not be very motivated to spend the time and effort to convince Congress to change the law. They might resent the dollar taken from them for a silly cause they don’t support, but the lost dollar isn’t worth the trouble of doing something about i...

If Data Is Supposed to Be Our Guide, the Great Coronavirus Shutdown of 2020 Should End

According to the most widely cited model projecting the course of the coronavirus outbreak, today is supposed to be Oklahoma’s peak in daily deaths. Now is a good time to go back to the beginning of the Great Coronavirus Shutdown of 2020, review the goal of our policy, and assess our current status. If our policy should be “data-driven,” as we are constantly told, then let’s actually look at the data and determine our next policy steps accordingly. Spoiler alert: according to the terms set out by those advocating for the shutdown policy, the policy’s continuance is no longer justified. The stated goal of the shutdown policy was to “flatten the curve” so as to prevent hospitals from becoming overwhelmed with COVID patients. The fear was that the virus would spread so fast that at its peak, the number of cases would exceed the overall capacity of the healthcare system. If that peak could be stretched out over a longer period of time, lives would be saved. This concept was il...

Even If Pandemic Models Were Right, Were Covid Lockdowns Wrong?

1889 has been quite critical of pandemic modeling that government officials have relied on for their Covid-19 response. We have also criticized shutdown orders in light of flaws in the models. But let’s assume for a moment that the worst predictions really would have come true if nothing was done. Even in those worst case scenarios, it’s fair to ask if our governments did the right thing. Were involuntary shutdowns justified, or would people have found a way to both limit the contagion and maintain some level of productivity? Was putting healthy citizens under house arrest acceptable even if they were willing to risk infection?   While large groups of people are often compared to herd animals, we are not sheep. We don’t behave like animals. We can, have, and will step up when our communities are in danger. When government and journalists give incomplete or false information, people will act irrationally. Depending on the situation, some will blindly follow the first aut...

Why Does Oklahoma License Polygraph Examiners?

Should polygraph examiners be licensed? In Oklahoma, a license is required to work as a polygraph examiner (a professional who applies lie-detector tests), and it is not at all obvious why. Generally, an occupation is licensed if it is obviously in the public’s interest to prevent potential bad actors from practicing. So, for example, it is argued that doctors must be licensed because, otherwise, some idiot might open a hospital in his garage and really hurt someone. And it is argued that accountants must be licensed because, otherwise, some college-dropout might offer to do accounting for an unsuspecting mom-and-pop shop, tell them their numbers look great (when, in fact, they don’t), and cause them to go bankrupt. In short, occupational licensing is supposed to either (1) prevent real, tangible harm, or (2) assure customers that their service-provider is trustworthy. However, interestingly, licensing polygraph examiners does not accomplish either of those goals because polygraph e...
