Completed Working Papers

NEW: Growing Like Germany: Local public debt, local banks, low private investment (with Michael Stiefel (UZH) and Iryna Stewen (JGU Mainz)). (CEPR-DP 15912)

The upshot:  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.

NEW: Softening the Blow: U.S. State-Level Banking Deregulation and Sectoral Reallocation after the China Trade Shock (with Lilia Ruslanova), September 2020, updated April 2021.

The upshot: U.S. state-level banking deregulation during the 1980s  considerably dampened the fallout on local economies of the China trade shock a decade later. The reason: households in financially integrated areas could more easily borrow against their housing wealth to smooth consumption. This kept house prices and wages in the non-tradable sector up, facilitating labor reallocation away from manufacturing.

NEW: Non-US  banks and dollar (co-)dependence:  how housing markets became internationally synchronized with Torsten Ehlers (BIS) and Alexander Raabe (European Stability Mechanism) now out as BIS-DP no 897 (29 Oct 2020).

The upshot: Why do  House Prices move together across countries? US capital inflows ease Dollar funding conditions for non-US global banks, which increases their lending globally. This drives mortgage supply and synchronizes house prices internationally.
