I think from my own experience from market days, the customer has some power as I would choose from among the many vendors with the best price. However, as Andrei pointed out, if the item is scarce, then if I really want the item, I have to pay the high price from the vendors, who would have the power. Here's what is available on ResearchGate:

I don't like to be old fashion, but I think market forces, strategic theories, and demand trends apply here.... I don't feel they apply differently through IS, or any specialized applications.. they might seem different, but still apply...

Very interesting answers and opinions..thank you all
