Here are the results from Session 1 of the Experiment (the picture phones)

In the class, the distribution of initial values was as follows.

Four people had initial value 1.
Four people had initial value 2.
Four people had initial value 3.
Three people had initial value 4.
Three people had initial value 5.
Three people had initial value 6.

The Network externality factors were as follows.

If the total number of phones sold was in the range 1-3, the network externality factor was 1.
If the total number of phones sold was in the range  4-6, the network externality factor was 2.
If the total number of phones sold was in the range 7-9, the network externality factor was 3.
If the total number of phones sold was in the range 10-12, the network externality factor was 4.
If the total number of phones sold was in the range 13-15, the network externality factor was 5.
If the total number of phones sold was 16 or larger, the network externality factor was 6.

In Round 1, the price was $15 and  no phones were sold.
In Round 2, the price was $11 and 17 phones were sold.  All of the people with initial values of 2 or higher bought phones.

We did not conduct rounds 3 or 4.
