Size matters in banking. In this paper, we explore whether shocks originating at large banks affect the probability of distress of smaller banks and thus the stability of the banking system. Our analysis proceeds in two steps. In a first step, we follow Gabaix [Gabaix, X., 2008a. The Granular Origins of Aggregate Fluctuations. Available at SSRN: http://ssrn.com/abstract=1111765] and construct a measure of idiosyncratic shocks at large banks, the so-called Banking Granular Residual. This measure documents the importance of size effects for the German banking system. In a second step, we incorporate this measure of idiosyncratic shocks at large banks into an integrated stress-testing model for the German banking system following De Graeve et al. (2008). We find that positive shocks at large banks reduce the probability of distress of small banks.

This paper analyzes the existence of flights from stocks to bonds and vice versa. We propose a definition and a test for flight-to-quality, flight-from-quality and cross-asset contagion and examine their characteristics and effects for the financial system. The empirical analysis for eight developed countries including the US, the UK, Germany and Japan shows that flights exist and are a common feature in many crises episodes. Our findings also reveal that flights are not merely country-specific events but occur simultaneously across countries. This indicates that there is a link between the occurrence of flights and cross-country contagion. Moreover, we show that flights enhance the resiliency of the financial markets by providing diversification benefits in times when they are needed most.

There is a considerable amount of research that seeks to determine the extent to which retail market participants exert market discipline on banks either through the price approach (the correlation of price to risk), or the quantity approach (the movement of funds in response to changes in risk). In this paper we propose and implement a third approach: the retail market conditions approach. We seek to determine if the prerequisites for the exertion of effective market discipline by stakeholder monitors, as set out in Llewellyn and Mayes (2003. The role of market discipline in handling problem banks. Bank of Finland Discussion Papers. extlesshttp://www.bof.fi/eng/7_tutkimus/index.stm extgreater (retrieved 13.04.04)), prevail by directly examining conditions that prevail among retail market participants. We find little evidence to support the proposition that they are being met among New Zealand retail depositors.

We estimate the impact of macroeconomic news on composite stock returns in three emerging European Union financial markets (the Budapest BUX, Prague PX-50, and Warsaw WIG-20), using intraday data and macroeconomic announcements. Our contribution is twofold. We employ a larger set of macroeconomic data releases than used in previous studies and also use intraday data, an excess impact approach, and foreign news to provide more reliable inferences. Composite stock returns are computed based on 5-min intervals (ticks) and macroeconomic news are measured based on the deviations of the actual announcement values from their expectations. Overall, we find that all three new EU stock markets are subject to significant spillovers directly via the composite index returns from the EU, the U.S. and neighboring markets; Budapest exhibits the strongest spillover effect, followed by Warsaw and Prague. The Czech and Hungarian markets are also subject to spillovers indirectly through the transmission of macroeconomic news. The impact of EU-wide announcements is evidenced more in the case of Hungary, while the Czech market is more impacted by U.S. news. The Polish market is marginally affected by EU news. In addition, after decomposing pooled announcements, we show that the impact of multiple announcements is stronger than that of single news. Our results suggest that the impact of foreign macroeconomic announcements goes beyond the impact of the foreign stock markets on Central and Eastern European indices. We also discuss the implications of the findings for financial stability in the three emerging European markets.
