Supplier Fixed costs and Retail Market Monopolization

Stéphane Caprice, Vanessa von Schlippenbach, and Christian Wey


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 when both intra- and interbrand competition exist. Our findings contradict the common wisdom that fixed costs do not affect market outcomes.
