Macroprudential Policy and Intra-group Dynamics: The Effects of Reserve Requirements in Brazil
IWH Discussion Papers,
This paper examines whether intra-group dynamics matter for the transmission of macroprudential policy. Using novel bank-level data on the Brazilian banking system, we investigate the effect of reserve requirements targeting headquarter banks’ deposit share on credit supply by their municipal bank branches. For identification purposes, we exploit that reserve requirements are adjusted following global economic cycles. Our results reveal a lending channel of reserve requirements for branches whose parent banks are more exposed to targeted deposits. Branch ownership and exposure to internal liquidity are central in explaining the results. Our findings reveal limitations in current macroprudential policy frameworks.
Central Bank Transparency and Cross-border Banking
Journal of International Money and Finance,
We analyze the effect of central bank transparency on cross-border bank activities. Based on a panel gravity model for cross-border bank claims for 21 home and 47 destination countries from 1998 to 2010, we find strong empirical evidence that a rise in central bank transparency in the destination country, on average, increases cross-border claims. Using interaction models, we find that the positive effect of central bank transparency on cross-border claims is only significant if the central bank is politically independent and operates in a stable economic environment. Central bank transparency and credibility are thus considered complements by banks investing abroad.
International Banking and Cross-border Effects of Regulation: Lessons from Germany
International Journal of Central Banking,
Supplement 1, March
We analyze the inward and outward transmission of regulatory changes through German banks’ (international) loan portfolio. Overall, our results provide evidence for international spillovers of prudential instruments. These spillovers are, however, quite heterogeneous between types of banks and can only be observed for some instruments. For instance, domestic affiliates of foreign-owned global banks reduce their loan growth to the German economy in response to a tightening of sector-specific capital buffers, local reserve requirements, and loan-to-value ratios in their home country. Furthermore, from the point of view of foreign countries, tightening reserve requirements is effective in reducing lending inflows from German banks. Finally, we find that business and financial cycles matter for lending decisions.
The Importance of Localized Related Variety for International Diversification of Corporate Technology
Internationalization of research and development has increased substantially in recent years. This paper analyses the determinants of spatial distribution of foreign technological activities across 96 regions in Germany. It identifies foreign technological activities by applying the cross-border ownership concept to patent applications. The main proposition is that regions with higher related variety of technological activities between sectors attract more foreign technological activities. The estimations show that this is the case in regions characterized by a high overall technological strength. This suggests that related variety facilitates technological diversifications of foreign corporations in regions at the top of the geographic hierarchy.
Risikobewertung von Staatsanleihen im Euroraum während der Staatsschuldenkrise von Ansteckungseffekten getrieben
Wirtschaft im Wandel,
Die europäische Staatsschuldenkrise hat in vielen Ländern zu Zinsaufschlägen auf Staatsanleihen geführt. Dies war vor allem in den Jahren 2010 und 2011 in Ländern wie Griechenland, Italien oder Spanien zu beobachten. Zur gleichen Zeit blieben die Kreditrisiken deutscher oder französischer Staatsanleihen auf einem moderaten Niveau. Trotz der unterschiedlichen Entwicklung in den Niveaus findet man ein hohes Maß an Gleichbewegung von Kreditrisiken in den Ländern des Euroraums. Dieser Beitrag untersucht, inwieweit dies durch strukturelle Ähnlichkeiten, internationale Verflechtungen und globale Marktentwicklungen erklärt werden kann.
Sovereign Default Risk and Decentralization: Evidence for Emerging Markets
European Journal of Political Economy,
We study the impact of decentralization on sovereign default risk. Theory predicts that decentralization deteriorates fiscal discipline since subnational governments undertax/overspend, anticipating that, in the case of overindebtedness, the federal government will bail them out. We analyze whether investors account for this common pool problem by attaching higher sovereign yield spreads to more decentralized countries. Using panel data on up to 30 emerging markets in the period 1993–2008 we confirm this hypothesis. Higher levels of fiscal and political decentralization increase sovereign default risk. Moreover, higher levels of intergovernmental transfers and a larger number of veto players aggravate the common pool problem.
