Capital maintenance econometrics for the 2009 review

Consultation (27 pages, PDF) on issues arising in relation to the econometric models used as part of the estimation of capital maintenance expenditure requirements in the Ofwat price control review 2009. The paper focuses on the choice of explanatory variables in the various models and the specification of data to be collected through the capital maintenance econometric return. It does not discuss how the results of the econometric modelling might be used, or the possible application of a future expenditure adjustment.
