We discuss the benefits of net neutrality regulation in the context of a two-sided market model in which platforms sell Internet access services to consumers and may set fees to content and applications providers on the other side of the Internet. When access is monopolized, we find that...

This paper questions whether competition can replace sector-specific regulation of mobile telecommunications. We show that the monopolistic outcome prevails independently of market concentration when access prices are determined in bilateral negotiations. A light-handed regulatory policy can...

I generalize the workhorse model of network competition to include income effects in call demand. Empirical work has shown call demand to increase significantly with income. For any positive income effect, network operators prefer a termination rate above marginal cost if networks are...

We analyse network competition in a market with international calls. National regulatory agencies (NRAs) have incentives to set regulated termination rates above marginal cost to extract rent from international call termination. International network ownership and deregulation are alternatives...

I generalize the workhorse model of network competition to include income effects in call demand. Empirical work has shown call demand to increase signi ficantly with income. For any positive income effect, network operators prefer a termination rate above marginal cost if networks are...

We extend the workhorse model of network competition to international calls. This model enables us to show that national regulatory authorities (NRAs) maximizing domestic welfare have incentives to increase termination rates above the social optimum to extract rent from international call...

In a 'smart' electricity distribution network, flexible distribution resources (FDRs) can be coordinated to improve efficiency. But coordination enables whoever controls such resources to exercise market power. The paper establishes the following efficiency rankings of market structures:...

We study the role of capital requirement in immigrants' self-employment decision with the help of a reform implemented in Sweden in 2010 which reduced capital requirements for limited liability companies. For both men and women, the reform increased both the probability of starting a limited...
