Info Value = the added accuracy the markets provide relative to other mechanisms, times the value that accuracy can give in improved decisions, minus the cost of maintaining the markets, relative to the cost of other mechanisms.

Robin Hanson:

A highly accurate market has little value if other mechanisms can provide similar accuracy at a lower cost, or if few substantial decisions are influenced by accurate forecasts on its topic.

[&#8230-] I meant trying to field the highest value applications. That is naturally measured in accounting terms – value minus cost. Measures of popularity or familiarity would not at all be the same thing.

Robin Hanson:

[One should] try to offer a cost-benefit calculation. You could count how many employees had ever gone to a TQM meeting, but that wouldn&#8217-t tell you if TQM is valuable or not.

Bo Cowgill:

[&#8230-] Trade-by-trade data can reveal characteristics of specific working groups: What they know, how they feel, how they process and share information and how all of that changes over time. I didn&#8217-t try to put any of this in the paper because the conclusions would be sensitive, and I thought this application was pretty obvious to anybody who understood our methodology. [&#8230-]

Bo Cowgill:

I&#8217-ve also heard that other companies would find it impossible to analyze the interaction between their market and the organization. Why? Lack of data. [&#8230-]

Bo Cowgill:

Some more remarks about applications that combine prediction markets and organizational data (org charts, social networks, seating locations). The obstacle to these applications is not a lack of data. Jed mentions privacy concerns &#8212- and if he thinks this is a big obstacle then I&#8217-d be interested in discussing his thoughts.

A bigger problem is that that current prediction market vendors and consultants cannot support these applications. At heart, these vendors are software engineers and salespeople at heart, not statisticians or data miners. They want to write one system that can support lots of clients. At conferences, one hears PM vendors complain about having to do &#8220-customization&#8221- work for clients.

This approach would not work for the applications I describe for two reasons:

  1. The inputs for different clients won&#8217-t be the same. Each client&#8217-s organizational data will likely take a different structure. This makes it difficult for prediction market vendors to architect a single system that can served many clients (yet another challenge with integrating markets with other corporate IT services).
  2. The outputs for different clients won&#8217-t be the same. The business relevance and statistical power of each analysis will differ with each client&#8217-s data.

Prediction market vendors may also need to familiarize themselves with the statistical learning methods necessary to fully utilize these rich datasets. So what&#8217-s the solution? First, move to a software-and-consulting model. By &#8216-consulting,&#8217- I don&#8217-t mean &#8216-consulting on how to implement the market.&#8217- I&#8217-m talking about helping the client solve its problem using a variety of data, including prediction market data.

Second, the vendors also need to pitch prediction markets as more than a forecasting tool. People in the business world commonly identify as data junkies &#8212- probably more so than they identify with the &#8216-wisdom of crowds&#8217- ethos. It is unclear how much companies really care about accurate forecasting anyway.

On a related note, there is something that only the prediction market software vendors could do, at this time, for those who are in capacity to do so: setting up inter-industry prediction markets &#8212-or at least, handing over (with everybody&#8217-s agreement) anonymized prediction market data on industry topics to anyone else in the industry who is a client of that PM firm. I don&#8217-t know about NewsFutures or Inkling Markets, but if you look at Consensus Point&#8217-s list of clients, you&#8217-ll see that David Perry&#8217-s firm is strong in the (consumer) electronic industry &#8212-Motorola, Qualcomm, Siemens, Nokia. Use your imagination, or ask David Perry directly, for more&#8230- (I can&#8217-t talk- otherwise, next thing, I&#8217-m a dead blogger.)&#8230-

Did you know that Real Clear Politics (a political news aggregator in bed with InTrade) is now owned by Forbes?

No GravatarI didn&#8217-t know that. (They also own Investopedia.)

And now Forbes are selling ad spaces for Real Clear Politics and 400 other politics blogs, thru their &#8220-Forbes Audience Network&#8221-. They sent me an e-mail, last year, to get us in their network. But a close look at their proposed contract showed that they would offer only 40% for Midas Oracle &#8212-whereas the other ad networks would offer 60%.

By the way, I&#8217-ll tell you later about my master plan to develop Midas Oracle&#8230-
