The paper provides a comprehensive survey of the economics behind the fight against hard core cartels. Differentiating between four subsequent stages - characterisation, welfare effects, enforcement and evaluation - the paper pays particular attention to cartel detection methods, the derivation...

Although the future socio-economic benefits of a new fibre-based ('next generation access', NGA) telecommunications infrastructure seem to be uncontroversial, a universal NGA coverage appears to be a rather unrealistic objective without government intervention. We contend, however, that the...

Our survey reviews the theoretical and empirical literature on all alternative policies to promote the deployment of new fiber-based communications infrastructure. Since such investment is expected to induce substantial positive externalities, dynamic efficiency becomes a particularly important...
