Abstract

We examine the effect of an oligopolistic upstream electronic market on upstream and downstream prices. The analysis highlights the two sources of competition that a firm that source from an electronic market (e- market firm) face: competition with less efficient firms that source traditionally (t-market firms) and competition among e-market firms. When size of the upstream e-market is small, the first effect dominates and there is higher profits with lower upstream prices in the e-market. When size of the e-market becomes very large, the second effect makes e- market firms less profitable than t-market firms even though e-market price may start to increase (as market size increases). As consequence, e-market will never completely eliminate the upstream t-market and downstream price can increase when e-market grows beyond a certain size.
