We study the interaction of customer capital and productivity through brand reallocation across firms. We develop a firm dynamics model with brands as transferable customer capital, heterogeneous firm productivity, and variable markups. We study the matching process between transferable brand...

Network shares and retail prices are not symmetric in the telecommunications market with multiple bottlenecks which give rise to new questions of access fee regulation. In this paper we consider a model with two types of asymmetry arising from different entry timing, i.e. a larger reputation for...

According to static models of industrial organization, a rise in competition decreases prices. In this paper, I test whether this conclusion can be reversed in the mobile telecommunications markets where dynamic efficiency effects might be significant. The empirical test relies on the change in...

The literature on the licensing of an innovation has mainly focused on some specific contract types. We show within the framework of a fairly general model that removing these contractual limitations will lead to extreme market outcomes. Specifically, we find that when the patentee can employ...

Posada and Straume (J Econ 83:243–265, <CitationRef CitationID="CR5">2004</CitationRef>) analyze a three-firm model of a circular city where two of the firms merge and may choose to relocate. They propose an equilibrium with relocation where taking part in the merger yields higher profits than staying outside, i.e., relocation may solve...</citationref>

We investigate the profitability and locational effects of two-firm Cournot mergers in the circular city. As compared with the linear market, we find that mergers turn out to be unprofitable much earlier.

This paper applies the ‘hypothetical monopolist’ test of market definition to a retail market with products differentiated by means of location and other dimensions. The test for defining the relevant product and geographic market follows the conditions required by the European Union...

In industrial organization analysis one of the most studied subject is product differentiation. In most cases it is considered an anticompetitive strategy carried out by dominant firms. In this work we tried to ask to ourselves what is the real role played by this strategy in the market. To...

We introduce a cost of location into Hotelling’s (1929) spatial duopoly. We derive the general conditions on the cost-of-location function under which a pure strategy price-location Nash equilibrium exists. With linear transportation cost and a suitably specified cost of location that rises...

We analyze the effects of consumers' limited attention on welfare in a model of horizontal product differentiation. We present a novel approach of modeling limited attention: an attention radius. Each consumer only notices goods that are within her attention radius, i.e., goods that are...
