[Computational Complexity] The Big Aggregators
- Friday morning I wanted to know where the rumors were pointing to for McCain's running mate selection. I could have searched various political blogs, but instead I went to Intrade and checked out the current prices on VP candidates. Since Intrade has constant trading, these prices do aggregate the various rumors and their veracity. Sarah Palin was running at about 60%. Apparantly I was not the only one with this idea has Intrade had major performance problems on Friday.
After seeing the price for Palin, I had a question many other Americans were asking: Who is Sarah Palin? So I went to that other great aggregator Wikipedia and read up on her. The scariest part: For the first time, someone on a major party ticket is younger than me.
The wisdom of crowds boiled down to a number on a trading site and a constantly updated page with much more than I need to know. The rest of the Internet is just commentary.
Some graphs of Intrade's market on the Palin market lifetime and in the last day.
Two things to note: The markets didn't predict Palin until close to the end. Also big volatility in the closing hours. Market aggregate public information—they don't predict what isn't out there. In the last hours, even little rumors, accurate or inaccurate, can drive prices as some people try to make a fast buck.
I created a simple widget for our Electoral Markets Map. You can see in on the left sidebar until the election and always have the most up to date account of who's ahead state by state.
