Amazingly, when I reloaded the page the next day, both priced had gone UP! Each was now nearly $2.8 million. And whereas previously the prices were $400,000 apart, they were now within $5,000 of each other. Now I was intrigued, and I started to follow the page incessantly. By the end of the day the higher priced copy had gone up again. This time to $3,536,675.57. And now a pattern was emerging. On the day we discovered the million dollar prices, the copy offered by bordeebook was1.270589 times the price of the copy offered by profnath. And now the bordeebook copy was 1.270589 times profnath again. So clearly at least one of the sellers was setting their price algorithmically in response to changes in the other’s price. I continued to watch carefully and the full pattern emerged.

Once a day profnath set their price to be 0.9983 times bordeebook’s price. The prices would remain close for several hours, until bordeebook “noticed” profnath’s change and elevated their price to 1.270589 times profnath’s higher price. The pattern continued perfectly for the next week.

fun analysis!

Trump: My net worth fluctuates, and it goes up and down with the markets and with attitudes and with feelings, even my own feelings, but I try. Ceresney: Let me just understand that a little. You said your net worth goes up and down based upon your own feelings?

Trump: Yes, even my own feelings, as to where the world is, where the world is going, and that can change rapidly from day to day ...

Ceresney: When you publicly state a net worth number, what do you base that number on?

Trump: I would say it's my general attitude at the time that the question may be asked. And as I say, it varies.

Just in time for Easter, an Israeli television journalist has produced a pair of nails he says may have been used to crucify Jesus Christ. "Were not saying these are the nails," says Simcha Jacobovici, holding aloft a pair of smallish iron spikes with the tips hammered to one side. "Were saying these could be the nails."

seriously?

 On Wednesday morning I stopped by the SoHo Apple store in New York City to purchase an iPad for a family member. As I had anticipated, a store clerk said they were out of stock and recommended that I check back the following morning. When I asked what time I should arrive, the clerk hesitated, looked around as if about to tell me a secret and said: “Well, do you see that group of people outside? They’re already here waiting for tomorrow’s shipment of iPads.”

I looked, and saw that outside the store sat a small group of Chinese men and women ready with camping chairs and apparently all the time in the world, preparing for a chilly night on New York’s streets as they waited to buy the iPad 2.

...

The people I saw waiting outside the SoHo store mostly refused to answer questions about what they were doing. But one man, who looked to be around 40 years old and declined to share his name, said he could make up to $400 a day by purchasing and reselling the iPad 2. As I reported last year, this is more money than many Chinese immigrants make in a week.

wow!

 We can now get an understanding of how the industry behaves with and without various platforms. The chart at the left gives the various growth rates of the market with platforms isolated from each other. I apologize for the shape of the chart but the scale does not permit a concise visual.
