Against the background of remunicipalisation trends in European public service sectors, this paper estimates firm-level productivity for German electricity retailers and tests whether the ownership type has a significant impact on productivity. We specify a production function for the retail sector with labour and external services as main inputs, which is estimated using a control function approach. Employing a newly constructed dataset on German utilities by the German Federal Statistical Office for the years 2003-12, we find that firm-level productivity generally increased until 2008 but not afterwards. We do not find any evidence for ownership having an impact on productivity.
