New paper in Journal of International Economics

Our paper “Small firms and domestic bank dependence” with Egor Maslov and Bent Sorensen has been accepted at the Journal of International Economics. 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.

Will sanctions on Russia work?

In a recent TV interview I have given the Swiss channel Tele Z, I had a chance to discuss with my host Claudia Steinmann the implications of sanctions for the Russian and western economies. We also talked about whether or not China is going to benefit from the situation. In this post, I follow up on my interview and elaborate a little more on whether sanctions will work or not. In the next post, I plan to write a little more on how I see the role of China.

Russia’s war in Ukraine, SWIFT sanctions and the Renminbi as an international currency

In a couple of interviews on Swiss Italian language radio RSI this weekend (here (from minute 18), here (from minute 8) and here), I argued that the SWIFT sanctions were the right thing to do and we already see their short-term impact in the form of a de-facto collapse of the Russian banking system: people are hoarding cash (credit cards have stopped working, they are ultimately based on the US infrastructure and the SWIFT payment systems) bringing the banking sector to crumble. And the firepower of the Russian central bank in terms of currency stabilization has been severely curtailed because its foreign-currency reserves (which of course are not sitting as dollar cash piles in its vaults but on foreign bank accounts) have effectively been seized. The effect has been a collapse of the rouble and will be high domestic inflation, coupled with the collapse of many small private firms which will no longer have access to bank credit.

New paper in the Journal of International Economics

The paper By a Silken Thread: regional banking integration and credit reallocation during Japan’s lost decade (with Toshihiro Okubo), has been accepted by the Journal of International Economics. We show how the geographical reallocation of credit dampened regional heterogeneity in business cycles during Japan’s lost decade. Even though large, country-wide (“integrated”) banks were most affected by the property crisis in the major cities, they reduced their lending less in areas where they had many bank-dependent SME customers all while reducing credit to big corporates who increasingly turned to bond issuance.

How high local public debt and local public banks crowd out private investment in Germany – and what the debt brake has to do with it

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.

European Forum at Beijing University, Oct 17th 2020

I had the honor to represent the University of Zurich at the 2020s European Forum of the School of Economics at Beijing University. My slides on Learning from the China Trade Shock: Lessons for European Monetary Union in a Post-COVID World are based on my recent UZH Econ DP with Lilia Ruslanova.
