| This paper investigates how the ownership and the procedure for the selection of firms operating in the local public transport sector affect their productivity. In order to compare different institutional regimes, we carry out a comparative analysis of 72 companies operating in large European cities. This allows us to consider firms selected either through competitive tendering or negotiated procedures. The analysis of the data on 77 European firms over the period 1997-2006 indicates that firms operate under constant returns to scale. Retrieving the residuals we obtain a measure of total factor productivity, which we regress on firm and city characteristics. We find that when firms are totally or partially in public hands their productivity is lower.... |

| Competition in public utility sectors has been encouraged in recent years throughout Europe. In this paper we try and analyse the welfare effects of these reforms in Italy, with particular attention to water and energy goods. The first step is to introduce a sensible measure of affordability of public utilities and to see how many households fall below a critical threshold. This issue is analysed stressing how climatic conditions dramatically affect households expenditure and how the affordability of utility bills varies a lot from region to region. So far, utilities reforms do not seem to have produced negative effects on the weaker group of households. |
