In a four-treatment experiment, we test some of the hypotheses inGarcia-Gallego et al.(2004) concerning competition among a number offirms of which some (or all) are indexed by a price-comparison enginefacilitating buyers' search process. In this paper, we isolateindividual behavior from noise...

In Portugal, the telecommunications incumbent offers broadband access tothe Inter- net, both through digital subscriber line and cable modem. Inthis article, we estimate the impact on broadband access to the Internetof the structural separation of these two businesses. We use a panel ofconsumer...
