There is an increasing convergence between postal products and telecom applications which suggests the need for a co-evolution of regulation. But there is hardly any discussion in academia or in practice about the consequences for regulation. Relevant questions are: Which parts of current regulation will become redundant? Is there additional regulation needed due to new bottlenecks or changes in consumer behavior? In our qualitative analysis, we investigate the implications of intermodal competition and growing convergence between postal and telecommunications services on regulatory institutions and regimes. We set up a comparison between the networks and compare the scope of universal services and issues concerning market power regulation in the two different industries.
