No one makes you shop at Wal-Mart

The title of Tom Slee's book, No One Makes You Shop at Wal-Mart, is ironic; Slee's goal is to show why this response to the success of Wal-Mart is inadequate.  More generally, Slee attacks MarketThink:

In the world according to MarketThink, the combination of choice and the market is a mechanism for solving problems and improving outcomes in areas as diverse as education, city growth and culture.

Hmmm...sound familiar?  (The links, also ironic, are mine not Slee's.)  Let the irony continue, I recommend No One Makes You Shop at Wal-Mart. 

Slee's book is the best of the anti-market books: it is well written, serious, and knowledgeable about economics.  In fact, I regard Slee's book as an excellent primer on asymmetric information, free riding, externalities, herding, coordination problems and identity - Economics 301 for all those budding young Ezra Klein's of the world who think that Economics 101 isn't quite right.

Here is one bit.  Early on Slee makes a good point about preferences and outcomes:

The prisoner's dilemma shows how, as soon as one person's choice alters the outcome for another person...choices do not reveal preferences...instead of thinking about choices as revealing preferences, it pays to think of choices as 'replies' to the actions or likely actions of others.  The best choice you can make is the best reply to the likely actions of others.

Later, he drives the point home with a nice example:

Faced with the observation that few children walk to school anymore, we commonly hear that this tendency represents our preferences: that "people won't walk" anymore.  But this is oversimplified.  What we are seeing is one equilibrium among many, and perhaps not the best one.  There is an equilibrium in which no one wants their children to walk along empty streets, and so no children walk, but there is another equilibrium in which many children enjoy walking with groups of other children, and parents feel safe about their children because there is safety in numbers on the busy sidewalks.

...Too many cities have concluded that empty sidewalks are a result of our preferences...but once a city takes it as a given that most children will be driven to school, there is no need for the city to even build sidewalks in new subdivisions, and there is more temptation to build fewer, bigger schools rather than more, smaller, easily accessible schools.  With these decisions, the empty-sidewalks equilibrium becomes even more entrenched: we are trapped in an outcome that was the result of individual choices, but that may not represent our true preferences.

Naturally, I have some criticisms which I will save for the extension.

In increasing order of seriousness.

As noted, the heart of the book is a well-written primer on let's call it new economics.  As such, this book would make a good supplement to an advanced undergraduate class.  But the activism and attacks on MarketThink are occasionally distracting.  Chapter 1, for example, opens with a denunciation of inequality.  Nothing wrong with that but Slee doesn't even attempt to show that there is any connection between rising inequality and the failure of MarketThink theories.  He just lumps things he doesn't like into one pile. If there were no asymmetric information, no herding, no coordination problems and so forth I guarantee that there would still be plenty of inequality.

For the most part, Slee illustrates the new economics with insightful, interesting and often new examples.  But there are clunkers.  I almost threw the book at the wall when he started talking about QWERTY.  Surely, Slee knows that this worn-out example is a joke?  The supposed superiority of the DVORAK keyboard was shown in studies conducted by ... Dvorak.  See here.  It's especially annoying that Slee did not reference, Winners, Losers & Microsoft.

As primer, it's fine to illustrate with examples and move on but as an attack on markets one expects a balanced consideration of opposing theories.  For example, Slee looks at beer micro-breweries vs. mass brewers arguing that we are currently stuck in the bad mass-equilibrium because micro-breweries rely on word-of-mouth but the institutions which sustain the word-of-mouth equilibrium only work when there are already lots of micro-breweries about which one can talk.  Nice, but here is an alternative theory.  Economies of scale made mass produced beer cheaper and when push came to shove consumers chose the cheaper good product over the more expensive but slightly better product (I don't eat at 5 star restaurants every night).  New technologies, however, have made micro-brewing more economic and as they have done so we are moving to the mass-customization world that Slee prefers.  Consumers have gotten the best of all worlds - given scarcity - in both time frames.  The beer activists in England that Slee likes moved the process along but in the direction that it was already going.

There is no comparative analysis in the book at all.  No discussion, for example, of how free riding, asymmetric information, herding etc. distorts government choice.  Also, no appreciation that what some of us MarketThink people really advocate is civil society which includes non-profits and voluntary collective action of all kinds.  And, no we are not all corporate shills (p. 106). 

It's true that outcomes do not always illustrate preferences but often they do.   Maybe people really do not want to walk to school.  It's subtle but Tom seems all too eager to call in the government to force us into the better equilibrium.  I worry when people start talking about how government can help us to express our true preferences.  Isn't this what dictators always say?  True freedom is oppression. 

The chapter on power is terrible, I did throw the book against the wall.  Perhaps in order to prepare us to welcome government as the deliverer of our true preferences, Slee wants to diminish the distinction between liberty and coercion.  But a true liberal should never write things like this:

...the formal structure of democracy and free markets is not enough to rule out exploitation and plunder - characteristics usually associated with repressive regimes.

If Tom visits GMU (I happen to know he reads MR) he should watch out because I shall kick him in the shins stating, "I refute you thus."

More seriously, repressive governments around the world threaten, rob, torture and murder with impunity.  Courageous individuals have died trying to escape such regimes while others have died fighting for their rights.  No matter how great are differences in wealth, it is morally wrong to equate what goes on in repressive regimes with capitalist acts between consenting adults.

Thanks for this excellent review.

"the formal structure of democracy and free markets is not enough to rule out exploitation and plunder - characteristics usually associated with repressive regimes."

Perhaps its the lack of context, but I see nothing very objectionable in this. It strikes me that only a particularly uncharitable reading would interpret him as morally equating the two systems.

I think the bit about breweries is a bit skewed:
"Economies of scale made mass produced beer cheaper and when push came to shove consumers chose the cheaper good product over the more expensive but slightly better product"

Prior to *prohibition* the U.S. had a great diversity of breweries iirc. When prohibition was the law of the land, only the giant brewers had the resources to survive. Smaller breweries either sold out or shut down.

It seems to me that it wasn't consumer preference that drove a preference for mass produced beer, but big-G government interference in legislating morality and squashing a market.

1) Thanks for the review.
2) On the subject of freedom and repression, one of the most fundamental tests of any polity is, "Which way do the border guards face?" Those who remember the Berlin Wall may recall that more people were shot trying to get out of East Berlin than trying to get in.

Slee's example about multiple equilibria re children walking being an application of the Prisoners Dilemma is confused and wrong. In the Prisoners Dilemma, there's only one equilibrium, involving dominant strategies. There's an outcome in dominated strategies that's better for the participants, but that's often super hard to sustain due to the attraction of the dominant strategy. (That's why some smart folks several thousand years ago came up with stuff like "morals" and rules like "Thou shalt not steal"). What he's talking about in the example is a coordination game with multiple equilibria, not a Prisoners Dilemma at all. Unless you mischaracterize his example, I would regard this as a serious error and a fundamental misunderstanding of the very theories he's attempting to use to attack markets.

The "new economics" is awfully self serving. If you can't "reveal your own preferences", then it takes elites to do so. Guys like... Tom Slee.

What I enjoy about economics is its positiveness. N

Hey, it's not unlike the studies of the Dvorak keyboard!

Prohibition had some historical importance, but the barriers to entry to microbrewing are not so high that you would expect a policy that was repealed in the '30s to have much effect.

Posted by: Zach at May 18, 2007 9:59:30 AM

Don,

Slee does not use the prisoner's dilemma to explain the coordination game. He uses the pd to explain that outcomes don't tell you about preferences when people's choices are tangled. Then he drives *that* point home with many other examples. Thus any confusion should be attributed to my wording in the review not to Slee.

I will at least agree that it's upsetting that so many people use the "No one makes you shop at Wal-mart" defense. But then, many less-refined Wal-mart critics' claims in fact reduce to a claim that people are too stupid to know what's best for them.

A serious discussion of the issue would recognize that e.g. if some law heavily favors big-box stores, it may not be forcing you to shop at Wal-mart, but it is artificially skewing your incentives to the winner in the big-box store race, which is probably Wal-mart. But this is hard for me to agree with since, if anything, Wal-mart has bigger hurdles to face than smaller stores.

And in your defense?

Zach,

Prohibition ended in the thirties but many regulations of alcohol production remained.

The microbrew renaissance had its first formal declaration when President Jimmy Carter signed a bill in early 1979 legalizing home brewing on a much larger scale than previously allowed. The Cranston Bill (named for Democratic Sen. Alan Cranston of California) gave license to the American public, and his constituents in Northern California, to begin the hobby of brewing their own, authentic beer (Jones, sidebar). A few years later, noticing the regional, grass-roots business of the craft brewing movement, the Oregon legislature enacted what became the most lenient brewing law for any state to date, allowing a greater output and easing distribution restrictions.

According to the link above it was not till 1979 that micro brewing started to be legalized.

It took additional years for the first state to start changing the laws in a way that would allow a micro brewery to be economically feasible.

Zach,

Re: MicroBreweries, Prohibition may have been repealed in the '30s, but the thick layers of bureaucracy regarding alcohol sales still exists. It's difficult for small brewers to sell across state lines, just as it's difficult for small wineries to do the same.

Buzzcut cuts to the heart of the matter: so how do we determine what our "true" preferences are if we are not actually choosing them for ourselves? In the "New Economics", the answer always seems to be "government bureaucrats" who are going to determine, through their greater enlightenment, what is actually best for us poor fools. Even with purely democratic governmental action, I challenge anyone to demonstrate that the outcomes in total will ever be as or more reflective of true preferences than those demonstrated by the sum of individual, voluntary transactions.

Indeed, the examples that Tabarrok highlights from Klee's book seem to be very, very weak cases to me:

In the case of beer, I have yet to find a single place in the United States where one cannot get beer from microbrewaries, if that is what one wishes to choose.

In the case highlighted by the ironic title of the book (doubly ironic, in my opinion), I have yet to see any Walmart location, and I have seen over a hundred, that did not also include the entire gamut of retail-store types, including the mom-pop types that are so beloved by the new economists and others on the Left. So, yes, it is enough to state that "no one makes you shop at Walmart" since Walmart is not a monopoly.

The case of children walking/not walking to school needs a more in-depth examination. Let us grant that some parents would have their children walk to school if some critical mass of other parents also choose this option. However, if not enough parents choose the option, then no one does; so, what is lost? Nothing prevents like-minded parents from aggregating their children into groups that are safe enough to walk to school, and, if they are unable to gather this critical mass, the only other option is to coerce the choice on others. Indeed, in this example where there is no critical mass for safety, it is still a choice not to cooperate to make the option "available". Extending this to the argument that developers then start producing housing divisions lacking sidewalks, again, I say, so what is lost? There is still housing being produced with sidewalks, and it is a choice people make to live in one type or the other.

In summary, if the the review is any indication of the content, I would have to pass on this book. Almost every similar argument against the free market I have read basically reduces to a desire to prevent free transactions of certain types that the new economists don't like- like shopping at Walmart, eating Big Macs, forgoing health insurance, or working for sub-minimum wages.

Alex,

Your alternative theory on lack of microbrew was

Economies of scale made mass produced beer cheaper and when push came to shove consumers chose the cheaper good product over the more expensive but slightly better product.
My alternative theory is government action ensured that the citizens had no choice to make.

1. Government action (prohibition) killed the infrastructure and knoweldge base needed for microbrewing to exist. It also killed the consumer base of customers who were used to and liked the craft brewed style of beer.

2. Ongoing government regulations made micrbrewing illegal into the 1980s (at least).

3. Ongoing government regulation and rent seeking by existing beer distributors place micro brewing at a commercial disadvantage to major brewers. The major brewers can afford a platoon of lawyers, and lobbyists, microbrewers can't.

The link below gives a good example of the massive effort needed to deal with regulatory and legislative issues.

Government Affairs & Legal Update - February 2006

Micro brewing will continue to grow but thanks to government action it is at least 50 years behind where it would have been.

The pernicious impact of many government regulations across wide segments of society and the negative impact they have on civil society are often not recognized.

Alex, thanks for the clarification. I've been thinking some more about Slee's argument for the potential existence of multiple equilibria embodied in the example of children walking to school (or not). I think what bothers me most is the absence of empirical support for his assertion. One would think that if coordination is possible on either equilibrium, there would be some communities that coordinate on the "walking" equilibrium, just as Great Britain and Japan coordinate on the driving-on-the-left equilibrium. Moreover, if this equilibrium is preferred, folks will reveal this preference by voting with their feet (there's those darn markets again) and moving into such communities. Evidence for this is thin on the ground. And so Slee is left to argue that markets don't allow people to express their true preferences, because people's true preferences are what Slee says they are. In short, the position of the tyrant.

Posted by: Don at May 18, 2007 11:33:04 AM

This is essentially a "search" problem. We can get "stuck" in a local optimum, where people take actions given a certain context, reinforcing the suboptimal situation.

It seems reasonable to suppose that special action may be required to find the optimum. I would be interested to know the theory on how to take such special action.

Since the government is the people (in an ideal democracy), it is not clear that the government is the best tool for this. Why can't people just decide, without the government, that something special must be done?

This must have been written about before. Can anyone recommend a resource?

Exactly!

Posted by: Yancey Ward at May 18, 2007 12:03:16 PM

I suppose some options are the following:

1) A bunch of more-or-less isolated individuals "suck it up" and make otherwise suboptimal choices on the hope that, with enough like-minded people, the situation will eventually change.

2) A bunch of passionate people start an organization devoted to coordinated action in pursuit of the new optimum. Social camaraderie, the pleasant feeling of improving the world, and some estimate of the expected gain from achieving the new world all factor into motivation.

3) Individuals band together without a formal organizational structure, and make coordinated decisions in pursuit of the new optimum. Again, social camaraderie and the hope of improving the world are part of the motivation.

4) Individuals or organizations lobby the government to create the conditions favorable for the new optimum. This has the advantage of tapping into a large pool of tax revenue, as well as the power to coerce, if the lobbying is successful.

One irony that Alex does not quite make explicit is that libertarians like him support a substantially different society too-- and have their own vision of the global optimum, which may be hard to achieve because it is fairly far away from the status quo. There are all sorts of coordination games (lobbying, government largesse) supporting the current welfare state.

As Alex and others have said, the real question is not whether suboptimal situations arise, but rather how we decide which situations are "more optimal", and how to pursue those different optimums.

"This must have been written about before. Can anyone recommend a resource?"

I don't have a resource to recommend, but I heard William F. Buckley say something at a campus lecture about 10 years ago that seems relevant: "Nothing magical happens to dollars to make them worth more if they first pass through Washington before being spent on public programs."
