    The Productivity Shock in Business Services

    In Germany, the productivity of professional services, a sector dominated by SME, declined by 40 percent between 1995 and 2014. Similar developments can be observed in several other European economies. Using a German dataset with 700,000 firm-level observations, we analyze this largely undiscovered phenomenon in professional services, the fourth largest sector of the business economy in the EU-15, ...

    Firms with superior productivity, labeled superstar firms, are argued to be the link between rising concentration and the fall of the aggregate labor share in the US.

One of the much discussed mechanisms behind this development ...

We apply a structural production function approach to a large panel of German water utilities between 2003 and 2014. Exploring variation of population density and the population age structure across service areas and over time, we provide evidence that demographics and their changes significantly ...

    Do Private Utilities Outperform Local Government-Owned Utilities? Evidence from German Retail Electricity

    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. ...
