“Super Debt Cities: Local government finance, political connections and the geography of China’s housing boom” with Yi Huang (Graduate Institute Geneva) and Ye Zhang (University of Geneva).
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.
NEW, revised version: By a Silken Thread: regional banking integration and credit reallocation during Japan’s lost decade (with Toshihiro Okubo), now out as UZH Economics Discussion Paper no 102.
The upshot: During Japan’s Lost Decade, regional credit reallocation by nationwide (“integrated”) banks mitigated the real effects from the bank liquidity shock in prefectures with many bank-dependent SMEs. We propose a novel instrument for regional banking integration that exploits the historical segmentation of banking markets in Japan that goes back to the institutions set up for silk export finance in the late 19th century. Our results show how integrated banking markets limit macroeconomic asymmetries in a monetary union during a financial crisis–even if the crisis mainly affects integrated banks (as was the case during the Lost Decade).
NEW, revised version: Small Firms and Domestic Bank Dependence in Europe’s Great Recession with Egor Maslov (UZH, Finance) and Bent Sørensen (U Houston) now out as UZH Economics DP 397.
The upshot: After the inception of the euro, the real economy in most member countries remained dependent on credit by domestic banks, which increasingly funded themselves through cross-border interbank funding. We find that this pattern of ‘double-decker’ banking integration exposed domestic banks to sharp declines in cross-border interbank lending during the eurozone crisis. As a result, domestic banks reduced lending which led to large declines in output in sectors with many small (bank-dependent) firms. We propose a quantitative small open economy model to account for these patterns and conclude that a global banking shock leading to a sudden stop in cross-border interbank lending in the eurozone is required to account for them.
