This paper uses a rich survey of 6446 households in Slovakia to estimate price elasticities of demand for Internet access, and draw implications for market definition. We estimate a mixed logit model, in which households choose between different broadband technologies: DSL, cable modem, fibre,...

Price concentration studies investigate the relationship between market concentration and price levels. They are increasingly used in the mobile telecom industry. This paper provides a detailed account of the limitations of such studies. In addition, it proposes a specific approach in order to...

This paper analyses how different types of access regulation to next generation networks affect investments and consumer welfare. The model consists of an investment stage with uncertain returns and subsequent quantity competition. The access price is a function of investment costs and the...

In our paper targets, by setting a reserve price, screen acquirers on their (expected) ability to generate merger-speci?c synergies. Both empirical evidence and many common merger models suggest that the di?erence between high- and low-synergy mergers becomes smaller during booms. This implies...

Network industries with low sunk costs have been popular examples for the theory of contestable markets and spatial competition models. We argue that, due to the multimarket nature of operations, theories of predation are more relevant to explain strategic behaviour. Building on well established...

Merger activity is intense during economic booms and subdued during recessions. This paper provides a non-financial explanation for this observable pattern. We construct a model in which the target-by setting the takeover price-screens the acquirer on his (expected) ability to realize synergy...

Current anti-predation rules are designed to detect and prevent actions that are only taken to drive out a rival. We evaluate the performance of these rules in a simple entry game. We find that the rules used by competition authorities fail to encourage sustained competition in the market....

This paper analyses how different types of access regulation to next generation networks affect investments and consumer welfare. The model consists of an investment stage with uncertain returns and subsequent quantity competition. The access price is a function of investment costs and the...

One of the potential benefits of an economic approach to State aid control is to make relationships between the costs and the benefits of State aid more transparent and, by doing so, to provide guidance on how to focus State aid control efforts on those areas where the damage of State aid is the...
