Synopsis
Author of the extremely popular "Dear Economist" column in Financial Times, Tim Harford reveals the economics behind everyday phenomena in this highly entertaining and informative book. Can a book about economics be fun to read? It can when Harford takes the reins, using his trademark wit to explain why it costs an arm and a leg to buy a cappuccino and why it's nearly impossible to purchase a decent used car. Supermarkets, coffee houses, airlines, insurance companies and more are sucking money from our wallets. To protect ourselves and our bank accounts, we must better understand why companies do what they do. Hailed by Publishers Weekly as "unequaled in its accessibility," The Undercover Economist is a sheer delight-and the one book on economics that every American should read.". a book on economics that will enthrall its readers. Beautifully written and argued, it brings the power of economics to life. This book should be required reading ."-Steven D. Levitt, author of Freakonomics

Who Pays for Your Coffee?
The long commute on public transportation is a commonplace experience of life in major cities around the world, whether you live in New York, Tokyo, Antwerp, or Prague. Commuting dispiritingly combines the universal and the particular. The particular, because each commuter is a rat in his own unique maze: timing the run from the shower to the station turnstiles; learning the timetables and the correct end of the platform to speed up the transfer between different trains; trading off the disadvantages of standing room only on the first train home against a seat on the last one. Yet commutes also produce common patterns—bottlenecks and rush hours—that are exploited by entrepreneurs the world over. My commute in Washington, D.C., is not the same as yours in London, New York, or Hong Kong, but it will look surprisingly familiar.
Farragut West is the Metro station ideally positioned to serve the World Bank, International Monetary Fund, and even the White House. Every morning, sleep-deprived, irritable travelers surface from Farragut West into the International Square plaza, and they are not easily turned aside from their paths. They want to get out of the noise and bustle, around the shuffling tourists, and to their desks just slightly before their bosses. They do not welcome detours. But there is a place of peace and bounty that can tempt them to tarry for a couple of minutes. In this oasis, rare delights are served with smiles by attractive and exotic men and women—today, a charming barista whose name badge reads “Maria.” I am thinking, of course, of Starbucks. The café is placed, inescapably, at the exit to International Square. This is no quirk of Farragut West: the first storefront you will pass on your way out of the nearby Farragut North Metro is—another Starbucks. You find such conveniently located coffee shops all over the planet and catering to the same desperate commuters. The coffee shop within ten yards of the exit from Washington’s Dupont Circle Metro station is called Cosi. New York’s Penn Station boasts Seattle Coffee Roasters just by the exit to Eighth Avenue. Commuters through Shinjuku Station, Tokyo, can enjoy a Starbucks without leaving the station concourse. In London’s Waterloo station, it is the AMT kiosk that guards the exit onto the south bank of the Thames.
At $2.55 a tall cappuccino from Starbucks is hardly cheap. But of course, I can afford it. Like many of the people stopping at that café, I earn the price of that coffee every few minutes. None of us care to waste our time trying to save a few pennies by searching out a cheaper coffee at 8:30 in the morning. There is a huge demand for the most convenient coffee possible—in Waterloo Station, for example, seventy-four million people pass through each year. That makes the location of the coffee bar crucial.
The position of the Starbucks café at Farragut West is advantageous, not just because it’s located on an efficient route from the platforms to the station exit, but because there are no other coffee bars on that route. It’s hardly a surprise that they do a roaring trade.
If you buy as much coffee as I do you may have come to the conclusion that somebody is getting filthy rich out of all this. If the occasional gripes in the newspapers are correct, the coffee in that cappuccino costs pennies. Of course, the newspapers don’t tell us the whole story: there’s milk, electricity, cost of the paper cups—and the cost of paying Maria to smile at grouchy customers all day long. But after you add all that up you still get something a lot less than the price of a cup of coffee. According to economics professor Brian McManus, markups on coffee are around 150 percent—it costs forty cents to make a one-dollar cup of drip coffee and costs less than a dollar for a small latte, which sells for $2.55. So somebody is making a lot of money. Who?
You might think that the obvious candidate is Howard Schultz, the owner of Starbucks. But the answer isn’t as simple as that. The main reason that Starbucks can ask $2.55 for a cappuccino is that there isn’t a shop next door charging $2.00. So why is nobody next door undercutting Starbucks? Without wishing to dismiss the achievements of Mr. Schultz, cappuccinos are not in fact complicated products. There is no shortage of drinkable cappuccinos (sadly, there is no shortage of undrinkable cappuccinos either). It doesn’t take much to buy some coffee machines and a counter, build up a brand with a bit of adver- tising and some free samples, and hire decent staff. Even Maria is replaceable.
The truth is that Starbucks’ most significant advantage is its location on the desire line of thousands of commuters. There are a few sweet spots for coffee bars—by station exits or busy street corners. Starbucks and its rivals have snapped them up. If Starbucks really did have the hypnotic hold over its customers that critics complain about, it would hardly need to spend so much effort getting people to trip over its cafés. The nice margin that Starbucks makes on their cappuccinos is due neither to the quality of the coffee nor to the staff: it’s location, location, location.
But who controls the location? Look ahead to the negotiations for the new rental agreement. The landlord at International Square will not only be talking to Starbucks but to other chains like Cosi and Caribou Coffee, and D.C.’s local companies: Java House, Swing’s, Capitol Grounds, and Teaism. The landlord can sign an agreement with each one of them or can sign an exclusive agreement with only one. She’ll quickly find that nobody is very eager to pay much for a space next to ten other coffee bars, and so she will get the most advantage out of the exclusive agreement.
In trying to work out who is going to make all the money, simply remember that there are at least half a dozen competing companies on one side of the negotiating table and on the other side is a landlord who owns a single prime coffee-bar site. By playing them off against each other, the landlord should be able to dictate the terms and force one of them to pay rent, which consumes almost all their expected profits. The successful company will expect some profit but not much: if the rent looks low enough to leave a substantial profit, another coffee bar will be happy to pay a little extra for the site. There is an unlimited number of potential coffee bars and a limited number of attractive sites—and that means the landlords have the upper hand.
This is pure armchair reasoning. It’s reasonable to ask if all of this is actually true. After I explained to a long-suffering friend (over coffee) all of the principles involved, she asked me whether I could prove it. I admitted that it was just a theory—as Sherlock Holmes might say, a piece of “observation and deduction,” based on clues available to all of us. A couple of weeks later she sent me an article from the Financial Times, which relied on industry experts who had access to the accounts of coffee companies. The article began, “Few companies are making any money” and concluded that one of the main problems was “the high costs of running retail outlets in prime locations with significant passing trade.” Reading accounts is dull; economic detective work is the easy way to get to the same conclusion.
Strength from scarcity
Browsing through the old economics books on the shelf at home, I dug out the first analysis of twenty-first-century coffee bars. Published in 1817, it explains not just the modern coffee bar but much of the modern world itself. Its author, David Ricardo, had already made himself a multimillionaire (in today’s money) as a stockbroker, and was later to become a Member of Parliament. But Ricardo was also an enthusiastic economist, who longed to understand what had happened to Britain’s economy during the then-recent Napoleonic wars: the price of wheat had rocketed, and so had rents on agricultural land. Ricardo wanted to know why.
The easiest way to understand Ricardo’s analysis is to use one of his own examples. Imagine a wild frontier with few settlers but plenty of fertile meadow available for growing crops. One day an aspiring young farmer, Axel, walks into town and offers to pay rent for the right to grow crops on an acre of good meadow. Everyone agrees how much grain an acre of meadow will produce, but they cannot decide how much rent Axel should pay. Because there is no shortage of land lying fallow, competing landlords will not be able to charge a high rent . . . or any significant rent at all. Each landlord would rather collect a small rent than no rent at all, and so each will undercut his rivals until Axel is able to start farming for very little rent—just enough to compensate for the landlord’s trouble.
The first lesson here is that the person in possession of the desired resource—the landlord in this case—does not always have as much power as one would assume. And the story doesn’t specify whether Axel is very poor or has a roll of cash in the false heel of his walking boot, because it doesn’t make any difference to the rent. Bargaining strength comes through scarcity: settlers are scarce and meadows are not, so landlords have no bargaining power.
That means that if relative scarcity shifts from one person to another, bargaining shifts as well. If over the years many immigrants follow in Axel’s footsteps, the amount of spare meadowland will shrink until there is none left. As long as there is any, competition between landlords who have not attracted any tenants will keep rents very low. One day, however, an aspiring farmer will walk into town—let’s call him Bob—and will find that there is no spare fertile land. The alternative, farming on inferior but abundant scrubland, is not attractive. So Bob will offer to pay good money to any landlord who will evict Axel, or any of the other farmers currently farming virtually rent-free, and let him farm there instead. But just as Bob is willing to pay to rent meadowland rather than scrubland, all of the meadow farmers will also be willing to pay not to move. Everything has changed, and quickly: suddenly the landlords have acquired real bargaining power, because suddenly farmers are relatively common and meadows are relatively scarce.
That means the landowners will be able to raise their rents. By how much? It will have to be enough that farmers earn the same farming on meadows and paying rent, or farming on inferior scrubland rent free. If the difference in productiveness of the two types of land is five bushels of grain a year, then the rent will also be five bushels a year. If a landlord tries to charge more, his tenant will leave to farm scrubland. If the rent is any less, the scrub farmer would be willing to offer more.
It may seem odd that the rents changed so rapidly simply because one more man arrived to farm the area. This story doesn’t seem to explain how the world really works. But there is more truth to it than you might think, even if it is oversimplified. Of course, in the real world, there are other elements to consider: laws about evicting people, long-term contracts, and even cultural norms, such as the fact that kicking one person out and installing a new tenant the next day is just “not done.” In the real world there are more than two types of farmland, and Bob may have different options to being a farmer—he may be able to get a job as an accountant or driving a cab. All these facts complicate what happens in reality; they slow down the shift in bargaining power, alter the absolute numbers involved, and put a brake on sudden movements in rents.
Yet the complications of everyday life often hide the larger trends behind the scenes, as scarcity power shifts from one group to another. The economist’s job is to shine a spotlight on the underlying process. We should not be surprised if, suddenly, the land market shifts against farmers; or if house prices go up dramatically; or if the world is covered by coffee bars over a period of just a few months. The simplicity of the story emphasizes one part of the underlying reality—but the emphasis is helpful in revealing something important. Sometimes relative scarcity and bargaining strength really do change quickly, and with profound effects on people’s lives. We often complain about symptoms—the high cost of buying a cup of coffee, or even a house. The symptoms cannot be treated successfully without understanding the patterns of scarcity which underlie them.
“Marginal” land is of central importance
The shifts in bargaining power don’t have to stop there. While the farming story can be elaborated indefinitely, the basic principles remain the same. For example, if new farmers keep arriving, they will eventually cultivate not only the meadowland but also all of the scrubland. When a new settler, Cornelius, walks into town, the only land available will be the grassland, which is even less productive than scrubland. We can expect the same dance of negotiations: Cornelius will offer money to landlords to try to get onto scrubland, rents will quickly rise on scrubland, and the differential between scrubland and meadow will have to stay the same (or farmers would want to move), so the rent will rise on meadow too.
The rent on meadowland, therefore, will always be equal to the difference in grain yield between meadowland and whatever land is available rent-free to new farmers. Economists call this other land “marginal” land because it is at the margin between being cultivated and not being cultivated. (You will soon see that economists think about decisions at the margin quite a lot.) In the beginning, when meadowland was more plentiful than settlers, it was not only the best land, it was also the “marginal” land because new farmers could use it. Because the best land was the same as the marginal land, there was no rent, beyond the trivial sum needed to compensate the landlord for his trouble. Later, when there were so many farmers that there was no longer enough prime land to go around, scrubland became the marginal land, and rents on meadows rose to five bushels a year—the difference in productivity between the meadowland and the marginal land (in this case, the scrubland). When Cornelius arrived, the grassland became the marginal land, meadows became yet more attractive relative to the marginal land, and so the landlords were able to raise the rent on meadows again. It’s important to note here that there is no absolute value: everything is relative to that marginal land.
From meadows back to coffee kiosks
A nice story, but those of us who like Westerns may prefer the gritty cinematography of Unforgiven or the psychological isolation of High Noon. So, David Ricardo and I get no prizes for our screenwriting, but we might be excused, as long as our little fable actually tells us something useful about the modern world.
We can start with coffee kiosks. Why is coffee expensive in London, New York, Washington, or Tokyo? The commonsense view is that coffee is expensive because the coffee kiosks have to pay high rent. David Ricardo’s model can show us that this is the wrong way to think about the issue, because “high rent” is not an arbitrary fact of life. It has a cause.
Ricardo’s story illustrates that two things determine the rent on prime locations like meadowland: the difference in agricultural productivity between meadows and marginal land, and the importance of agricultural productivity itself. At a dollar a bushel, five bushels of grain is a five-dollar rent. At two hundred thousand dollars a bushel, five bushels of grain is a million-dollar rent. Meadows command high dollar rents only if the grain they help produce is also valuable.
Now apply Ricardo’s theory to coffee bars. Just as meadowland wil...
