Consumer switching costs cause the market demand of consumers who already bought a supplier's product to be less elastic while they simultaneously increase competition for new consumers. I study the effect of this twofold pricing incentive on firms' price setting behavior in a 2x2 factorial...

The upgrade of legacy infrastructure is a challenging undertaking in general. The underlying issues are especially prominent for telecommunications networks outside of urban areas. Using German micro-level data, we identify the structural determinants for fiber optics deployment and its extent....

Ad-avoidance technologies such as ad-blocking add-ons in browsers and supplemental mobile applications have become mainstream tools in recent years. Over time they surpassed their niche role as applications only for the technically savvy and became an essential tool for many internet users....

To shed more light on consumer-sided demand migration, we adapt Chen & Riordan's (2007) Spokes Model of spatial competition to a duopolistic-multi-product firm setting in which both firms simultaneously offer fibre and copper products comparable to Brito & Tselekounis (2017). Our model will be...

Digitale Märkte weisen starke Konzentrationstendenzen und eine Entwicklung zu immer stärker verzahnten, sich verschließenden Ökosystemen auf. In dieser Studie wird (ein Mangel an) Interoperabilität (IOP) als mögliche Ursache oder Treiber solcher Konzentrationstendenzen beleuchtet und der...

Consumer sided demand migration from legacy to fibre telecommunication technologies is a key challenge in today's economic policy. We adapt Chen and Riordan (2007) Spokes Model of spatial competition to capture a duopolistic multi-product firm setting in which an incumbent operator and an...

Ad-avoidance technologies such as ad-blocking devices in browsers have become mainstream tools in recent years and escaped their role as niche applications that are only for the technically savvy. While technical impacts of those tools are well researched, their effects on actual consumer...

In this paper, we analyze how wholesale access fees of a crucial input can be utilized to influence demands for products of different technologies and the deployment sequence between an incumbent and entrant firm. In a setting of multi-product competition with horizontally differentiated...

We analyze pricing patterns and price level effects of algorithms in the market segments for OTC-antiallergics and -painkillers in Germany. Based on a novel hourly dataset which spans over four months and contains over 10 million single observations, we produce the following results. First,...
