Sub-Saharan Africa ranks among the top regions in terms of growth in the number of mobile phone users. The success of mobile telephony is attributed to the opening of markets for private players and lenient regulatory policy. However, markets may be increasingly saturated and new regulations...

With Germany's nuclear phase-out, 23 reactors need to be dismantled in the near future. Initiated by the dire financial situation of the affected utilities in 2014, a major discourse on ensuring financial liability led to a redistribution of liabilities and finances, with the utilities remaining...

We analyze the effects of an incentive based regulatory scheme with revenue caps on the investment behaviors and decisions of 109 electricity distribution companies operating in Germany in 2006-2012. We hypothesize that Germany's implementation of incentive regulation in 2009 has a negative...

While the link between the ownership and productive efficiency of firms has been discussed extensively, no consensus exists regarding the superiority of one or the other in non-competitive, regulated environments. This paper applies a flexible production model to test for efficiency differences...

We analyze pricing and competition under paid prioritization within a model of interconnected internet service providers (ISPs), heterogeneous content providers (CPs) and heterogeneous consumers. We show that prioritization is welfare superior to a regime without prioritization (network...

The restructuring of telecommunication in Central and Eastern Europe occurs at a time when the classical structures of telecommunication are falling apart worldwide. Coming from the socialist system in which telecommunication did not exist as an independent economic activity, the Eastern...

We investigate the impact of competition policy enforcement on the functioning of European energy markets, and how sectoral regulation influences these outcomes. For this purpose, we compile a new dataset on the European Commission’s (EC) and EU member states’ competition policy decisions,...

A world of unequal carbon prices requires measures aimed at preventing carbon leakage. Climate policy imperatives demand that such measures must be compatible with the goal of sending a carbon price signal down the value chain. For carbon intensive materials, the combination of dynamic free...

Rising rents in German cities have led to an intense debate about the need for tighter rent controls in housing markets. In April 2015, the so-called rental brake was introduced, which imposes upper bounds for rents in new contracts, in order to immediately slow down the increase of rents in...

This paper explores whether governments can ban carbon-intensive materials through product carbon requirements. By setting near-zero emission limits for the production of materials to be sold within a jurisdiction, governments would accelerate the phase out of carbon-intensive production...
