Fixed And Variable Costs

These kinds of complaints betray an ignorance of business economics. One would expect that from Congress, but it would be nice to think that the American people are smarter (sadly, what with the clamor for “anti-gouging laws” and the like, there’s little evidence of it on the ground).

As Peter Suderman points out, the problem is that the cost of adding a cable channel is extremely low relative to providing the service in the first place. Like him (and no doubt many others) I am paying for many channels that I never watch, and will never watch, and wish that I could dump them for a lower satellite bill. But that’s not how the business model works.

It’s similar to the restaurant problem (which to my mind is one of the causes of the “obesity epidemic” among Americans, to the degree that it exists). The bulk of the cost of eating in a restaurant (unless it’s serving larks’ tongue pie and pan-fried snail darter) is overhead: rent, lighting, environmental control, power for cooking and refrigerating, wages, benefits, etc. I’m not sufficiently familiar with the business to know the exact numbers, but it wouldn’t surprise me if the cost of a meal, at least in a small place, was sixty to seventy percent overhead, with the rest going to the cost of the food itself. Say that it’s three quarters. That means that if you provide twice as much food, you only increase the cost of the meal by twenty-five percent (and the converse is that if you provided no food at all, but merely the ambiance and pleasure of having people wait on you, the price of a twenty-dollar meal would still be fifteen bucks).

There are various ways to compete in the restaurant industry, including branding, food quality, atmosphere, service, but one that’s of value to a lot of people is food quantity. Based on the economics described above, the latter is one of the cheapest things to increase, and much less costly than hiring better chefs, or classier waitpeople, or investing in a branding. This is particularly the case when you increase the quantities of really cheap food, such as starches and sugar. The fast food industry figured this out a while ago, with “biggie drinks” and “supersizing.” Giving the customer an extra potato’s worth of fries, or another spoon of corn sugar with flavored water added only pennies to the meal cost, but seemed to many customers to provide a bargain.

This is in fact why Mexican restaurants have such high profit margins relative to other cuisines. You rarely get good-quality meat (and if you do, you pay a lot more for the dish). It’s usually bits of chicken parts, shredded beef or pork, or (in some of the less reputable places) “meat”…, disguised in a hot sauce, and wrapped in a flat unrisen bread made of corn or wheat, combined with rice and beans. You can get stuffed with unhealthy high-glycemic carbs. Not to mention, of course, filling you up pre-meal on sectioned deep-fried corn tortillas and a chopped tomato sauce. It used to be that Mexican meals were cheap, relative to others, but once it became trendy, they started to make a killing, particularly the chains, charging as much for this low-cost meal as other restaurants do for meat that you can actually identify (at least as regards to species).

What’s worse is that these are exactly the kinds of excess calories that we don’t need. If they upped the protein, it would be much healthier for us, but that would cost much more (though even there, they’ve managed it, with double and triple burgers, but you’ll notice that there’s a much bigger price jump for these, since the meat and cheese are the most expensive parts of a burger). I’ve often wished that I could get a cheaper, smaller meal, but like the case of the bundled cable or satellite channels, the economics militate against it.

By the way, it should also be noted that misunderstandings of the difference between fixed and variable costs also lies at the root of many people’s ignorance about the source of high space launch costs, even among professionals in the space industry.

Saw The Launch

We watched it from the causeway west of Cocoa Beach. It was a beautiful evening for it–all of the clouds had cleared. I may put up some pictures tomorrow, if they look worth it. Off to bed now, a little after 1 AM.

Welcome, Lord British

In the non-space publication PC Gamer in the July issue, we find that video game celebrity and fellow Austinite Richard Garriott will have a regular column where we will find out about his PC Games from NC Soft like Tabula Rasa and also “what one says to Stephen Hawking while riding the ‘vomit comet.'”

While technically he rode ZEROG non-vomit comet with only 12 parabolas (which doesn’t give me much hope for the space editing in the magazine), Garriott’s space persona includes being Vice Chairman of Space Adventures, the company that has the most space tourism cost of goods sold. He is also the son of astronaut Owen Garriott.

So welcome, Lord British! And keep up the good work bringing science fiction to digital–and analog–life.

Fuel of the Future

From the May 2007 and May 1857 issue of Scientific American:

We believe that no particular use is made of the fluid petroleum, from the ‘tar springs’ of California, except as a lotion for bruises and rheumatic affections. It has a pungent odor, and although it can be made to burn with a pretty good light, its smell is offensive. This, perhaps, may be obviated by distilling it with some acid; we believe that this is not impossible in this age of advanced chemistry. If the offensive odor could be removed, a valuable and profitable business might be carried on in manufacturing burning fluid from it.

I find the hubris that we can predict we know what energy we will be using for lighting in 150 years astonishing. But whatever it is, if we project economically viable reserves vs. current usage, we can project we will run out of it. It’s a good thing we found a replacement for whale oil and tallow in time.

I think scientists and journalists misunderstand what ‘finite’ means when it comes to resources. Even a compact finite sphere can seem infinite if as you approach the edge, you slow down, the sphere grows, or your direction changes. When resources get scarce, price rises slows down usage, viable reserves grow, substitutes change usage patterns and magically–as if stayed by an invisible hand–we never run out of anything.

For thousands of years the only thing consistently getting more expensive is the value of human attention (Simon).

Per a comment:

Now, I consider myself a moderate libertarian and thus strongly disagree with them on this but while I am a strong believer in innovation and technological progress, the argument about finite resources does give me pause at times. What about industrial metal ores etc…?

Could we not at some point simply run out of materials to use?

I would point out that there’s no such thing as a non-renewable resource. Except, of course, time, and (ultimately) energy. It will be a very long time, though, before we run out of either, at least as a species.

By the way, Sam. What’s with all the marathon posting? Did you just lose your job? Not that I don’t appreciate it. Just sayin’…
