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...

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...

The publication of János Kornai's memoirs, By Force of Thought, provides an excellent opportunity to remind ourselves of Kornai's great contributions to economic research. This paper discusses both his basic research strategy and some of his main research results. Kornai has usually dealt with...

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 note provides sufficient conditions for immediate agreement in an extensive form model of interdependent bilateral bargaining. The model is suggested by Björnerstedt and Stennek (2006) as a work horse for studying bilateral oligopoly. The key feature of this model is that the firms are...

This paper investigates how the entry mode of foreign direct investment (FDI) affects the affiliate R&D activities using unique data on Swedish multinational firms over a long period of time (1970 to 1998). On average, acquired affiliates are more likely to do R&D and have a higher level of R&D...

The paper estimates the causal effect of trade liberalisation on aggregate productivity through mechanisms related to firm selection. The construction of a bridge in 2000 across the Öresund Strait linking Copenhagen with Malmö, Sweden's third largest city, provided a natural experiment with...
