We estimated a mixed logit model using data on the broadband technologies chosen by 94,388 subscribers of a single European broadband operator on a monthly basis between January and December 2014. We found that consumers have similar valuation of DSL connection speeds in the range between 1 and...

In this paper, we use a unique dataset on switching between mobile handsets in a sample of about 8,623 subscribers using tariffs without handset subsidies from a single mobile operator on a monthly basis between July 2011 and December 2014. We estimate a discrete choice model in which we account...

This thesis addresses theoretical and empirical questions related to network economics. In particular, it analyze network effects and switching costs in the mobile telecommunications industry. The first chapter analyzes competition in a two-period differentiated-products duopoly in the presence...

Abstract This paper analyzes competition in a two-period differentiated-products duopoly in the presence of both switching costs and network effects. We show that they have opposite implications on the demand side, specially in the first period. Switching costs reduce demand elasticities and...
