first mover advantage and preferential attachment

Postby teapack on Sun Mar 27, 2011 2:57 pm

Dear All

I'm trying to understand the difference between first mover advantage and preferential attachment, if there is one. My understanding is that Barabasi refers to preferential attachement as the likelyhood of established nodes to attract links at a greater rate than new nodes. My latest TMA (02) asks me to explain the difference between first mover advantage and random networks. I think first mover advantage and preferential attachment are the same am I wrong?

Thanks for your help, please note i'm not asking for the answer :)

i'd say 1st mover and preferential attachment are related, but not the same. Just because your node exists before anyone else's doesn't guarantee preferential attachment. In situations where a node has existed for longer and there is a preference for those attaching to go to more 'popular' nodes the first mover nodes would be attached to preferenitally in a positive feedback process. But there may be other drivers of preference than node size or age. Don't forget that many 'popular' internet nodes such as Altavista, (remember them?), have fallen by the wayside as people preferentally visit google for example.
I think you need one or other, or prefereably both factors to achieve success and 1st mover advantage may not be enough on it's own in the longer term.

First mover advantage becomes significant when it takes a fair bit of effort to set something up and there is a limited pool of customers.
Let us assume that it costs 10 000 pounds to set up a phone network and there are 1000 potential customers.
You spend the 10 000 and get the 1000 customers.
Any one following you will have to spend the 10 000 again but, even if he offers good pricing, wait for your customers to get out of their contracts.

there's no point responding to these posts, it's obviously spam, and Neill will deal with it. I'm pretty sure it's created by an automatic system, not a real person.
