Der in Gang befindliche Übergang von den klassischen Telekommunikationsnetzen zu "Next Generation Networks" bietet zwar hohe Innovationspotenziale, es besteht aber auch die Gefahr, dass marktmächtige Netzbetreiber ihre dominanten Positionen auf die bisher wettbewerblichen Märkte für...

There has been major debate in recent years about the speed and scale of technological innovation, and whether digital technologies create new issues relating to trust and ethics. This presentation will consider key issues around trust and ethics in the digital age, and the appropriate policy...

In a domestic market, a duopoly produces a homogeneous final good, pollution, pollution abatement and R&D. One of the firms (foreign) has superior technology. The government regulates the duopoly by levying a pollution tax to maximize domestic welfare. We consider the potential implementation of...

In a domestic market, a duopoly produces a homogeneous final good, pollution, pollution abatement, and R&D, which reduces abatement cost. One of the firms (foreign) has superior technology. The government regulates the duopoly by levying a pollution tax to maximize domestic welfare. We consider...

We propose a two-sided model with two competing Internet platforms, and a continuum of Content Providers (CPs). We study the effect of a net neutrality regulation on capacity investments in the market for Internet access, and on innovation in the market for content.Under the alternative...

We revisit Maxwell's (1998) analysis to show that MQS regulation has no effects on the high-quality firm's incentive to adopt a more efficient technology in a vertically differentiated duopoly with fixed costs of quality improvement and full market coverage

In today's technology-driven world, industry standardization, component interoperability, and product-compatibility have become critical to promoting innovation and competition. Standards are typically created by voluntary organizations (generally referred to as standard-setting organizations...

We propose a two-sided model with two competing Internet platforms, and a continuum of heterogeneous Content Providers (CPs). We study the effect of a net neutrality regulation on capacity investments in the market for Internet access, and innovation in the market for content. Under the...

The effects of a new firm's entry into the telecom service market are examined further. These consist of up- and downstream markets, corresponding to the first and second stages in game theory. When a new entrant can succeed in process innovation and lower production cost, entry of the entrant...
