Subsidizing real-money prediction markets and real-money conditional prediction markets

Should Google subsidize the Lunar X Prize contract on InTrade?

John Salvatier,

Our good friend Bo Cowgill might have already re-created those prediction markets on Google&#8217-s internal prediction exchange at a marginal cost of zero US dollar. No need for him to &#8220-subsidize&#8221- external prediction markets.

[As an appendix, I precise that I am in favor of opening the enterprise prediction markets to external traders, for some questions.]

Subsidizing prediction markets is an old Robin Hanson idea that carries quite a heavy price tag.

Conditional prediction markets is a great idea on the paper. Many people (e.g., Mike Linksvayer) like the idea. However, here is what the uncritical Robin Hanson fanboys blogging on Overcoming Whatever won&#8217-t tell you:

  • The first problem is that nobody trades those things.
  • The second problem is that subsidizing those conditional prediction markets costs an arm and a leg.
  • The third problem is that no major news media outlet has ever quoted the prediction market prices / probabilities generated by those conditional prediction markets.

Peter McCluskey could have rent a French mistress (or a French gigolo) for a full year with all the money he is spending on Robin Hanson&#8217-s idea. Or vaccinated the whole African continent against Malaria. See Peter&#8217-s comment, at the middle of the webpage, here.

Philanthropy and prediction markets are not mixing well &#8212-yet.

Here are the stats about the feed subscribers to these blogs who use either Google Reader or iGoogle.

To interpret these data, you should know that:

  • The web visitors are not counted.
  • The PC-based feed subscribers are not counted.
  • The Web-based feed subscribers who use other feed readers than Google are not counted.
  • In the case of Marginal Revolution, which was one of the defaults proposed by Google Reader until recently, many feed subscribers do not actually read this blog.
  • A vertical blog like Midas Oracle, which deals only with prediction markets, is necessary far less popular than more horizontal blogs, which can publish about everything (including sex, as it has been the case in the past with those 3 economics blogs).

Google Web Search shows that I am the only blogger in the world to talk about prediction market journalism.

Good thing: I&#8217-m a pioneer (following Justin Wolfers&#8217- footsteps).

Bad thing: The whole world does not give the first fig about &#8220-prediction market journalism&#8220-. We will spend much energy introducing them to this new concept.
