Can digital information and communication technology (ICT) foster mass political mobilization? We use a novel geo-referenced dataset for the entire African continent between 1998 and 2012 on the coverage of mobile phone signal together with georeferenced data from multiple sources on the...

We study the dual relationship between market structure and prices and between market structure and investment in mobile telecommunications. Using a uniquely constructed panel of mobile operators' prices and accounting information across 33 OECD countries between 2002 and 2014, we document that...

In recent years, regulatory bodies in Europe and around the world implemented Combinatorial Clock Auctions (CCA) to allocate scarce and valuable spectrum frequencies usage rights. Although the auction design is complex, the promise is that bidding becomes simple. More precisely, bidders may bid...

We evaluate the impact of a major European state aid programme for broadband deployment applied to rural areas in the German state of Bavaria in the years 2010 and 2011. Using matched difference-in-differences estimation strategies, we find that aided municipalities have – depending on...

This paper investigates regional or international transfers as a means to prevent immigration into unemployment. We analyze a two-country model with free migration in which the rich country is characterized by minimum wage unemployment. Matching grants for investment in infrastructure are...

Recent studies investigate policies motivating consumers to make an active choice as a way to protect unsophisticated consumers. We analyse the optimal timing of such choice-enhancing policies when a firm can strategically react to them. In our model, a firm provides an automatic enrollment or...

This paper reviews empirical evidence, especially from Europe, on how education and training policies can be designed to advance both efficiency and equity. Returns to educational investments tend to decrease over the life cycle. Moreover, they seem to be highest for children from disadvantaged...

Currently, U.S. and EU telecommunications policies differ in many respects. For example, wholesale access to local loops is largely deregulated in the U.S. but continues to be regulated in the EU. Or, the U.S. has an elaborate universal service policy with a set of universal service funds and...

This paper studies various options to support allowance prices in the EU Emissions Trading System (ETS), such as adjusting the cap, an auction reserve price, and fixed and variable carbon taxes in addition to EU ETS. We use a dynamic computable general equilibrium model that explicitly allows...

We analyze different options for the design of a common unemployment insurance system for the euro area (EA). We assess their effectiveness to act as an insurance device in the presence of asymmetric macroeconomic shocks. Running counterfactual simulations based on micro data for the period...
