Considering a vertical structure with perfectly competitive upstream firms that deliver a homogenous good to a differentiated retail duopoly, we show that upstream fixed costs may help to monopolize the downstream market. We find that downstream prices increase in upstream firms' fixed costs...

. Depending on the ratio of switching costs to network effects, our model generates convergence to monopoly as well as market … switching costs market sharing is the unique equilibrium and for small switching costs both monopoly and market sharing … equilibria emerge. We also analyze stationary and stable equilibria, where we show that a monopoly outcome is almost inevitable …

We present a model with firms selling (homogeneous) products in two imperfectly segmented markets (a "high-demand" and a "low-demand" market). Buyers are mobile but restricted by transportation costs, so that imperfect arbitrage occurs when prices differ in both markets. We show that equilibria...
