Chipotle vs. Moe’s: The Magnolia Street Burrito Showdown

Two goods are substitutes when the price of one increases and demand for the other increases. This phenomenon unfolds every week for me–the two goods being  burritos from Moe’s and Chipotle.

Every Monday, Moe’s offers a great deal on their burritos, conveniently called the “Moe Monday” deal. All burritos, from the Jr. Joey Bag of Donuts to the colossal Homewrecker, are $5.75, no matter the meat. This deal is hard to beat and hard to pass up.

Chipotle has no such deal.

And so, every week, substitution effects inexorably infiltrate my preferences, increasing my demand for Moe’s on Mondays–only on Mondays.

This is a bigger deal than it sounds, because I was for a long time a strict Chipotle apostle and evangelizer. Classmates wouldn’t even bother asking me where I wanted to go to lunch, in the same way you wouldn’t ask somebody wearing a clerical collar where they go to church, or invite somebody wearing a yarmulka over for a pork butt BBQ.

Over time, though, and because of the Moe Monday deal, Moe’s has grown on me. It’s a tex-mexistential crisis.

Let’s weigh the pros and cons for both.

  • Chipotle’s guacamole is the best–no exaggeration. It’s the best guacamole I’ve ever had. Moe’s’ guacamole was just a green paste, but they’ve redone their recipe. It’s not the best, but it is good. Chipotle wins the guacamole game.
  • Moe’s includes chips and a great salsa bar with their meals. The Who is Kaiser? and tomatillo salsas are my favorite. The Pineapple Cucumber salsa is surprisingly good, too, when they have it. Chipotle’s chips are an extra charge (on top of their already more expensive menu) and are just sitting behind the register in brown bags at room temperature. Moe’s is the chips and salsa champion.
  • Chipotle’s grilled veggies are fresh and flavorful. Moe’s’ veggies are less so, and sit in watery juices so they’re on the soggy side. I declare Chipotle’s veggies victorious.
  • As mentioned before, the Moe Monday deal is fantastic. At Chipotle, you have to work hard to keep your lunch bill under $10. It often means making trade-offs like no meat in exchange for the guacamole, or no guacamole in exchange for the chips or a drink, etc. Moe’s wins the price prize.
  • Chipotle raised the bar for the quality of their ingredients, and Moe’s has conformed to the new standard. Both have responsibly raised, hormone-free, and antibiotic-free meats (or do their best to have them). The steak comes from grass-fed cows (!). The guacamole is made fresh at both locations. I’d say Chipotle has higher quality ingredients when all are considered, but Moe’s is catching up. Chipotle is the narrow innards winner. Say that five times fast.

In conclusion, I have no conclusion. If it’s Monday and you’re hankering for a burrito, give Moe’s a try. On other days, Chipotle may be the better choice.

Link Parade: 5.22.15

I just read On Writing Well by William Zinsser a few days before he died last week. The book was great, but I especially appreciated his treatment of political speech and writing. Politicians take circuitous, winding routes to say what they want to say, and rely on a lot of platitudes. FEE acknowledged his passing and his remarks on F.A. Hayek’s writing.

Kansas has started charging fees for cash withdrawals of $25 or more for welfare recipients. Not really a part of what is now being called the “War on Cash” (since it is through welfare–if we are going to have public welfare, it should be in-kind), but we can still point to it as an example of the government discouraging the use of cash to have more oversight on people’s purchases and the use of their money.

Great posts on the Mises blog this week, including David Gordon on knowing the great thinkers in the history of economic thought, Ryan McMaken on the beepocalypse and the Fed’s performance on the Amazon bestseller listCarmen Dorobăț on the UK’s response to “negative inflation” (speaking of political language), and (obviously as a “best-of” type post) Rothbard on Adam Smith.

Adam Smith (1723-90) is a mystery in a puzzle wrapped in an enigma. The mystery is the enormous and unprecedented gap between Smith’s exalted reputation and the reality of his dubious contribution to economic thought.

Robert Murphy on people complaining about 88 cent gallons of water. I actually use these for coffee in the morning. Makes a much fresher tasting coffee than water from the tap.

Having a bad week? At least you (probably) didn’t lose $15,000,000,000.

Thou Shalt Not Overcomplicate Things

Justin Fox has a short piece at Bloomberg View that asks “What’s Wrong With ‘Mathiness’ in Economics?

He begins by characterizing (caricaturizing?) the pre-math economics profession as confused and garrulous philosophers:

Once upon a time economists made their arguments in long, discursive, often contradictory books…

Thankfully, Paul Samuelson brought math to the field like Moses brought the Ten Commandments down from Mount Sinai to the lost and wayward Israelites.

In the 1940s Paul Samuelson of the Massachusetts Institute of Technology brought enlightenment, in the form of elegant mathematical treatments of the major concepts in economics.


Samuelson’s approach gave the discipline a, well, discipline that it had previously lacked, and enabled economics to make great leaps in coherence and rigor.

But, just a few words later, Fox admits that

It also made the field incomprehensible to laypeople, but that turned out to be more a feature than a bug. Economists were seen as possessing unique scientific knowledge, and came to play increasingly prominent roles in public life in the U.S. and elsewhere.

Although I disagree with his first characterization of the pre-math economics and his regard for Samuelson’s influence, this last bit is where I want to parley with Fox.

The incomprehensibility of the math to the laypeople is the primary piece of evidence in the indictment against the current “mathiness” of economics. Economics is the study of those regular, ordinary laypeople making choices. Ordinary people make choices all the time, and so describing the nature or logic of their choices should be intuitive to them.

This does not mean that everybody automatically knows all of the deep and varied conclusions of economics just by making choices. It means that any explanation of how choice and interaction with other people making choices (like in markets) should be digestible without an advanced degree in another field like math or statistics. Choice and market interaction are so mundane and ubiquitous, explaining how they work should be simple, right?

I use this example frequently but it fits in well here: When you walk down the grocery store aisles, are you taking derivatives of utility functions? Or are you weighing your preference for each good against others and the money you are prepared to spend at the register?

Which of these two explanations for how people make choices would serve as a better foundation for the science that purports to study individuals making choices?

Fox doesn’t really answer the question posed in the title of his article: “What’s wrong with ‘mathiness’ in economics?” He just comments on Romer’s beef with the way mathematical models are overused and abused by even Nobel-winning economists. Fox quotes Romer:

Presenting a model is like doing a card trick. Everybody knows that there will be some sleight of hand. There is no intent to deceive because no one takes it seriously. Perhaps our norms will soon be like those in professional magic; it will be impolite, perhaps even an ethical breach, to reveal how someone’s trick works.

And I say no more magic. Drop the smoke, the mirrors, the rabbits, and their hats. Let’s drop the pretense–it is, after all, a violation of the Ninth Commandment.

You shall not bear false witness against your neighbor. (Exodus 20:16 ESV)

Defining economics

Today’s the first day of class for the Summer I term at Auburn, so I get to introduce and define economics for a fresh crop of students.

Economics is the study of individuals making choices. Since humans are the focal point, economics fits in the social science category, along with psychology, political science, sociology, and other fields. Economics differs from the others by asserting the primacy of the individual and asking “what sort of things pertain to all choices by anybody, not just certain types of people in certain situations?” The short answer is scarcity. The fact that the things that make us happy and help us survive don’t exist in superabundance is why we have economics. Every choice ever made by anybody was caused by scarcity. No scarcity, no choices, no economics.

“Selecting something over something else” implies a means-end causal connection. Our ends are our desires, or our wants. Means are anything that help us satisfy our ends. We can also call means “goods”. So, we select something over something else in order to satisfy an end by using a good.

The means at your disposal and the ends they satisfy exist in an array, a list, or a ranking. Said another way, satisfaction or happiness in the economic sense is ordinal, not cardinal. Our preferences are also invisible to others and reside only in our own singular mind, so they are subjective, too. Preferences are ordinal and subjective.

Preferences give way to opportunities to exchange and therefore prices, production, the division of labor, and supply and demand, all of which make up the body of thought we know as economics.

Little Italy Pizzeria

“If I could buy stock in this place, I would.”

– Alan Seals, Professor of Economics at Auburn University

A single slice of pizza requires two plates. Patrons order beer by the pitcher more often than single bottles. One whole sandwich is really two meals.

Stacks of fresh ingredients fill their subs. Cheese stretches as long as the Brooklyn Bridge when you pull a slice of the Cheese Lover away from your mouth. No heat lamps, just mammoth pizza ovens. There’s a fresh coat of flour on just about everything behind the counter–including the people, above whom wads of dough frequently spin and flatten centrifugally.

Quantity? Check. Quality? Check. It must be expensive then, right?

Their lunch special is hard to beat: half a sub sandwich or a slice of pizza with chips and a fountain drink for under $6. Substitute a side salad in for the chips and it’s only $1 more.

A pitcher of beer costs about as much as a pint elsewhere. A slice of pizza a la carte starts at $2. All the sandwiches (remember: two meals) are under $10. A calzone with three toppings comes in just under $10, too.

The service is fast and friendly, except when it takes them more than two tries to get you to come clear your food from the hot real estate that is their work space.

On top of all this, I’ve never had a bad time at Little Italy. Something about the place inspires fun and laughter, and it’s not just the beer that circles the table like an offering plate. We gladly pull up chairs at an already crowded table to make room for everyone. You hear others cheer for some game that’s on the TV. It’s a place for good times, making new friends, and laughing with old friends.

Ladies and gentlemen: Little Italy has it all. There is no comparison. There is no competition. Not in the South, anyways. Maybe not outside of New York. Maybe not even there.

Quotes of the week:

Here’s the thing. The Bernank thinks the Great Recession happened because teenage girls piled to the rafters in export company dormitories in China went on a savings binge. Purportedly, the Fed had nothing to do with expanding credit market debt outstanding by $22 trillion or nearly 6X the growth of nominal GDP during the short interval between the time he joined the Fed in 2002 and the massive Wall Street meltdown of 2008.

Blogger Ben’s Basically Full Of It – David Stockman

Economics may be a dismal science, but politics is a dismal superstition.

Jakub Bożydar Wiśniewski

Genuine enemy of humanity. A literal malefactor.

Tho Bishop, on this mean lady.

If you’re living high on that cheap credit hog
Don’t look for cure from the hair of the dog
Real savings come first if you want to invest
The market coordinates time with interest

Your focus on spending is pushing on thread
In the long run, my friend, it’s your theory that’s dead
So sorry there, buddy, if that sounds like invective
Prepared to get schooled in my Austrian perspective

Ryan McMaken quotes “Hayek” (with an “H”, pronounced like “high explosives”), for Hayek’s birthday, from Papola’s rap, on Keynes’s economics.
