Using econometric modelling and input-output economics, the analysis examines and measures the extent to which telecommunications has contributed to national and sectoral productivity performance. The main findings from this paper suggests that most industries have benefited from the incorporation of advances of telecommunications technology, which might have, amongst other things, emanated from encouraging infrastructure investment, in their production processes. Thus the analysis demonstrates that U.K. government policies on telecommunications and its investment incentives may have wide-reaching consequences for not only the telecommunications industry but also the economy as a whole.

These constitute the latest attempt to address discriminatory concerns infixed telecoms. This paper examines the incentives of vertically integrated operators with market power to discriminate using where possible empirical evidence relevant to the UK and considers possible regulatory responses to this behaviour. Finally, it briefly describes the remedy adopted by Ofcom to deal with this issue.

The approach employed differs from other UK studies in that panel data for a range of companies is used. This increases the number of observations and thus allows potentially for more robust tests for global subadditivity of the cost function. The main findings from the study reveal that although the results need to be treated with some caution allowing/encouraging infrastructure competition in the local loop may result in substantial cost savings.

The test allows to compare prices of providers of differentiated products on a like-for-like basis. Testing for pricing power could be a useful complement to more traditional or computationally and data demanding techniques in the assessment of market power. The test was applied to broadband Internet access services in Ireland and the Netherlands. Results appear encouraging as they are broadly aligned to the decisions of the regulatory authorities in both countries that the incumbent DSL operators had market power at the time.

While the focus is mainly on the economic regulatory developments in the UK, the conclusions and discussion should be relevant to all countries that have embarked on telecoms liberalization.
