			<content:encoded><![CDATA[<p>[IMPORTANT NOTE: This present post is critical of one point expressed by Nigel Eccles, but, overall, I like this Scottish guy, and I enjoy HubDub's prediction markets a lot.]</p>
<p>-</p>
<p><a title="Hubdub - The Vision Thing" href="http://blog.hubdub.com/2008/07/23/hubdub-the-vision-thing/">Nigel Eccles</a>:</p>
<p style="padding-left: 150px;"><strong>Quoting <a href="http://www.hubdub.com/">HubDub</a> forecasts in news stories about future events will be as common as quoting stock prices in financial stories is today or (in the UK) quoting betting odds for political elections.</strong></p>
<p>-</p>
<p>Nigel,</p>
<p>my good friend,</p>
<p>Quit drinking the <a href="http://en.wikipedia.org/wiki/Scotch_whisky">Scotch whisky</a> and listen up 2 minutes.</p>
<p>I appreciate the formidable effort you made to start up HubDub and I am delightful its prediction markets are now well traded. In that perspective, HubDub is already a success. And I agree that many HubDub prediction market prices are meaningful.</p>
<p>However, I strongly disagree with the idea that, at one point in the future, the free world&#8217;s journalists and bloggers will rush to quote HubDub&#8217;s market-generated probabilities. Here&#8217;s why.</p>
<p>See, my good Scottish friend, you&#8217;re not the first fellow to tackle this problem. A guy named Emile Servan-Schreiber, with another fellow named <a href="http://www.linkedin.com/pub/0/904/7b9">Maurice Balick</a>, created <a href="http://us.NewsFutures.com/">NewsFutures</a> (a play-money prediction exchange quite similar to HubDub, except that HubDub uses MSR whereas NewsFutures uses CDA) in the year 2000 &#8212;at the time most contemporary prediction market people were still drinking their mother&#8217;s milk.</p>
<p>For the Midas Oracle readers who are just surfacing from an Afghan cave, Emile Servan-Schreiber is:</p>
<ul>
<li>a veteran of the prediction market industry;</li>
<li>a well educated (PhD) and smart man;</li>
<li>a gifted exchange executive, with a very good understanding of Internet usability;</li>
<li>a successful entrepreneur (NewsFutures has been profitable for years);</li>
<li>the only international prediction market expert (NewsFutures has clients in North-America, Europe, and Asia);</li>
<li>the author of 2 academic papers on prediction markets (one of them established the predictive power of the play-money prediction markets);</li>
<li>one of the most often interviewed prediction market people;</li>
<li>well connected in the Academia (2 prediction market luminaries are on the NewsFutures scientific advisory board);</li>
<li>the winner of a bet he made against Justin Wolfers;</li>
<li>etc.</li>
</ul>
<p>In other words, Emile Servan-Schreiber is far from being a moron.</p>
<p><strong>Still, in 8 years of existence, NewsFutures&#8217;s prediction market prices have NEVER been quoted (over than occasionally) in the Mediasphere or the Blogosphere.</strong></p>
<p>What makes you think that a cocky Scottish guy will be able to achieve what a smart Frenchman has miserably failed to achieve?</p>
<p>-</p>
<p><strong>The answer to Nigel Eccles&#8217; mission statement resides in a collective effort from all prediction market people and organizations to favor the development of prediction market journalism.</strong></p>
<p>-</p>

<p>My thoughts:</p>
<ol>
<li>Do report<strong> the probabilities</strong>, not the prices.</li>
<li>Do not report spread info.</li>
<li>Do report probabilities from <strong>the very top, most liquid</strong> prediction markets, only.</li>
</ol>
<p>Michael Giberson and Jason Ruspini, what do you think?</p>
