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...

We analyze how the entry mode of Foreign Direct Investments (FDI) affects affiliate R&D activities. Using unique affiliate level data for Swedish multinational firms, we first present empirical evidence that acquired affiliates have a higher level of R&D intensity than greenfield (start-up)...

Why do so many high-priced acquisitions of entrepreneurial firms take place in network industries? We develop a theory of commercialization (entry or sale) in network industries showing that high equilibrium acquisition prices are driven by the incumbents' desire to prevent rivals from acquiring...

This paper studies an industry in which firms can choose to provide open or closed platforms. Open platforms, as opposed to closed, are extendable so third-party producers can develop extensions for them. Building on a two-sided market model, I show that firms might prefer to commit to keeping...

We construct a model where incumbents can either acquire basic innovations from entrepreneurs, or wait and acquire developed innovations from entrepreneurial firms supported by venture capitalists. We show that venture-backed entrepreneurial firms have an incentive to overinvest in development...

We develop a theory of commercialization mode (entry or sale) of entrepreneurial inventions into oligopoly, and show that an invention of higher quality is more likely to be sold (or licensed) to an incumbent due to strategic product market effects on the sales price. Moreover, preemptive...
