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...

We model competition between two unregulated mobile phone companies with price-elastic demand and less than full market coverage. We also assume that there is a regulated full-coverage fixed network. In order to induce stronger competition, mobile companies could have an incentive to raise their...

The impact of ICT on the efficiency of different national telecommunication industries of the US, Germany, France, the UK and the Netherlands is analysed by using a stochastic production possibility frontier approach. The relative inefficiencies of these industries measured as distances to the...

This paper analyses the issues of regulatory reform in the energy industry of post- Soviet countries. We identify the characteristics of the transformation that these countries go through: it is the introduction of a) a new legal culture and b) a capitalist rationality of production in societies...

The EU Emissions Trading Scheme (EU ETS) is the main instrument to reduce greenhouse gas emissions in Europe. Subject to a country specific limit, installations in the EU ETS can use EU allowances (EUA) and certified emissions reductions (CERs) generated through the Clean Development Mechanism...

We analyze various regulatory regimes for electricity transmission investment in the context of a transformation of the power system towards renewable energy. We study distinctive developments of the generation mix with different implications on network congestion, assuming that a shift from...

We discuss the implications of two price zones, i.e. one northern and southern bidding area, on the German electricity market. In the northern zone, continuous capacity additions with low variable costs cause large regional supply surpluses in the market dispatch while conventional capacity...

We investigate the welfare impact of parallel imports using a large panel data set containing monthly information on sales, ex-factory prices, and further product characteristics for all 700 anti-diabetic drugs sold in Germany between 2004 and 2010. We estimate a two-stage nested logit model of...

Many developing countries around the world apply progressive water tariffs, often structured in the form of discretely increasing block tariffs (IBTs). These tariffs have been criticized in the welfare economic literature due to their perceived inefficiency: many of the prices charged under IBTs...

To date, the distributive implications of incentive regulation on electricity transmission networks have not been explicitly studied in the literature. More specifically, the parameters that a regulator might use to achieve distributive efficiency under price-cap regulation have not yet been...
