Joel Liu's List: Free economics debates

From the consumer's perspective, though, there is a huge difference between cheap and free. Give a product away and it can go viral. Charge a single cent for it and you're in an entirely different business, one of clawing and scratching for every customer. The psychology of "free" is powerful indeed, as any marketer will tell you.

This difference between cheap and free is what venture capitalist Josh Kopelman calls the "penny gap." People think demand is elastic and that volume falls in a straight line as price rises, but the truth is that zero is one market and any other price is another. In many cases, that's the difference between a great market and none at all.

What's free: Web sites and services. Free to whom: all users, since the act of using these sites and services actually creates something of value.

You can get free porn if you solve a few captchas, those scrambled text boxes used to block bots. What you're actually doing is giving answers to a bot used by spammers to gain access to other sites — which is worth more to them than the bandwidth you'll consume browsing images. Likewise for rating stories on Digg, voting on Yahoo Answers, or using Google's 411 service (see "How Can Directory Assistance Be Free?"). In each case, the act of using the service creates something of value, either improving the service itself or creating information that can be useful somewhere else.

It does. The word is externalities, a concept that holds that money is not the only scarcity in the world. Chief among the others are your time and respect, two factors that we've always known about but have only recently been able to measure properly. The "attention economy" and "reputation economy" are too fuzzy to merit an academic department, but there's something real at the heart of both. Thanks to Google, we now have a handy way to convert from reputation (PageRank) to attention (traffic) to money (ads). Anything you can consistently convert to cash is a form of currency itself, and Google plays the role of central banker for these new economies.

There is, presumably, a limited supply of reputation and attention in the world at any point in time. These are the new scarcities — and the world of free exists mostly to acquire these valuable assets for the sake of a business model to be identified later. Free shifts the economy from a focus on only that which can be quantified in dollars and cents to a more realistic accounting of all the things we truly value today.

In this freeconomics world, startups still have a chance because startup costs are rock-bottom low. However, it is not enough to build a "killer app". They have to build a "killer honey pot" that uniquely attracts workers/customers that generate the content that both attracts page view "honey" and (virally) more workers/customers.

Is this bad or complex? Not really, just a different skillset. In this "honey pot" world, effective social architecture is more important than sheer quantity of application features. You don't charge (or charge much) for the "application." Instead, you harvest value out of the content/attention of your worker-bee customers.

One of the biggest problems that I have with the "free" argument, which you've mentioned in your article, is the whole idea of marginal costs of zero, or virtually zero. Generally speaking (and I can't think of a good counter-example), the only way that you get to such low costs is through significant capital investment and mass production so that, over time, fixed costs are distributed over a huge volume of product.

Anything that's mass produced, or mass distributed, still requires a rather large up front investment. That takes deep pockets, which many smaller companies don't have. You've indicated this above in your comments about Gmail overpowering Yahoo Mail (although Hotmail is still around...?)
