This paper reexamines the effect of the regulatory regime on both penetration and coverage of broadband access to the internet. The framework also allows for an evaluation of different public policy measures such as subsidization of broadband demand and supply. A welfare analysis asks what the...

This paper looks at the effects of different forms of wholesale and retail regulation on retail competition in fixed network telephony markets. We explicitly model two asymmetries between the incumbent operator and the entrant: (i) While the incumbent has zero marginal costs, the entrant has the...

In the beginning of fixed network liberalisation in Europe in the late 1990s, the main concern of regulators was to lower calls prices. This was done by introducing wholesale regulation and promoting service based competition. Some years later, the concern of some regulators turned from too high...

This paper models competition between two firms, which provide broadband Internet access in regional markets with different population densities. The firms, an incumbent and an entrant, differ in two ways. First, consumers bear costs when switching to the entrant. Second, the entrant faces a...

This paper analyzes the incentives to invest in Next Generation Access Networks (NGA) in a framework with horizontal product differentiation with price competition between an investing and an access seeking firm. Given uncertainty about the success of the NGA, I compare regulatory regimes with...

This paper shows how cognitive human dispositions that take effect at the level of an individual firm's corporate culture have repercussions on an industry's evolution. In our theory, the latter is attributable to evolving corporate cultures coupled with changes in a firm's business environment....

We apply a panel vector autoregression model to a firm-level longitudinal database to observe the co-evolution of sales growth, employment growth, profits growth and growth of R&D expenditure. Contrary to expectations, profit growth seems to have little detectable effect on R&D investment....

The paper examines the innovation dynamics of the mature camera market between 1955 and 1974. This highlights the importance of heterogeneous preferences in determining industry structure. By recognising and accommodating consumer heterogeneity, new firms engaged in radical product and process...

The adequate role of Darwinist concepts in evolutionary economics has long been a contentious issue. The controversy has recently been rekindled and modified by the position of "Universal Darwinism", most prominently favored by Geoffrey Hodgson and Thorbjørn Knudsen. They argue that the...

Considerable debate surrounds the concept of entrepreneurial opportunities. This paper contributes to the discussion by bringing in concepts and findings from evolutionary economics. It makes three points. First, adopting an evolutionary market process perspective sheds new light on the nature...
