In a recent column in VoxEU together with Michael Stiefel (UZH) and Iryna Stewen (JGU Mainz)) we discuss our new CEPR discussion paper Growing Like Germany: Local public debt, local banks, low private investment. The paper shows that local government debt in Germany crowds out private investment to the tune of 1 percent of GDP per year. The reason: Forced to lend to local governments by their statutory mandate, local public banks try to  “make up” for the low-yields on municipal debt by charging SME higher rates in what are locally segmented credit markets. This effect is exacerbated by the dire straits of municipal finances in Germany which, as we argue, is a direct consequence of the debt brake at the federal and state levels which shifted a lot of expensive government task to municipalities.
