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,...

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...

We study substitution from fixed-line to mobile voice access, and the role of various complementarities that may influence this process.We use rich survey data on 160,363 households from 27 EU countries during 2005-2012. We estimate a discrete choice model where households may choose one or both...

We use rich survey data on 133,825 households from 27 EU countries during 2005-2011 to analyze substitution between fixed-line and mobile telecommunications services. We estimate a discrete choice model where households may choose between having mobile or fixed-line voice access only, or using...

It is a common concern that pricing pressure by powerful buyers discourages suppliers' R&D investments. Employing a simple monopsonist - competitive upstream industry - framework, this paper qualifies this view in two respects. First, the monopsonist has an incentive to subsidize upstream R&D...

Abuyer’s technical knowledge may increase the efficiency of its supplier.Suppliers, however, frequently maintain relationships with additional buyers. Knowledge disclosure then bears the risk of benefiting one’s own competitor due to opportunistic knowledge transmission through the common...

This article analyzes cost-reducing R&D investments by firms that behave non-cooperatively or cooperatively. Firms face a trade-off between allocating their R&D investments to innovate or to imitate (absorb). We find that the non-cooperative behavior not only induces more imitation (absorption)...
