This paper provides evidence on the migration from an “old” technology to a “new” technology, taking into account the impact that regulatory interventions on the old one might have on the incentives to invest and adopt the new one. This analysis has been applied to a sample of EU27...

In this paper we study how the coexistence of access regulations for legacy (copper)and fiber networks shapes the incentives to invest in network infrastructure. To this end, we develop a theoretical model explaining investment incentives by incumbent telecom operators and heterogeneous entrants...

The growing momentum for gas price liberalization in Russia is increasingly constrained by fears of potentially strong adverse impact that market-based price setting principle will have on the economy. Based on a novel multi-regional, multi-sector and multi-household computable general...

Digital designs - that is, designs for display on electronic screens - have recently burst onto the intellectual property (IP) stage. While in the U.S. a smattering of legal studies have recently addressed the question of digital design as a copyright-, trademark- and patent-eligible subject...

This paper provides an overview of telecommunications regulation in the U.S. and in Europe. For each region the history of telecommunications regulations as well as the current regulatory regime is portrayed. The focus of this overview is on the question of how unbundling regulations in the...

We provide a structured overview of the quantitative literature on the economic impacts of telecommunications networks and broadband internet. Differentiating between wireline and wireless technologies as well as broadband availability and broadband adoption, respectively, we review studies...

The literature on the effects of telecommunications infrastructure investments find positive macroeconomic effects, however, it is severely constrained because it could hitherto only analyze investment up to "basic" broadband but not up to the newer generations of "fast" and "ultra-fast"...

Under ex ante access regulation entrants often claim that access fees are excessive. I show that this is only the case if further entry is admitted. If the entrant is protected from further entry it would agree with the incumbent upon a strictly positive access fee which may exceed the efficient...

We study the welfare effects of non-binding advance price announcements. Applying a differentiated Bertrand model with horizontal products and asymmetric information, we find that such announcements can help firms to gain information on each other thereby allowing them to achieve higher profits....

For the case of the German state of Baden-Wuerttemberg, production and employment effects of the promotion of renewable energy sources are examined based on a regionalized input-output table. Our findings suggest that policy actions promoting renewable energy types do not necessarily create new...
