In the light of the unconventional monetary policies implemented by most large central banks around the world, there is an intense debate about the potential impact on the prices of capital assets. Particularly in Germany, skepticism about the sustainability of the current policy by the European Central Bank is wide spread and concerns about the emergence of a speculative price bubble in the housing market are increasing. The present study analyzes a comprehensive data set covering 127 large German cities from 1990 through 2013, using tests for speculative bubbles, both at a national and city level. Furthermore, we apply two new testing approaches: panel-data and principal components versions of explosive root tests. We find evidence for explosive price increases in many cities. However, it is only in select urban housing markets that prices decouple from their fundamental values. There is no evidence for speculative price movements nationally.

The objective of this paper is to examine the relationship between bank characteristics, in particular

value, performance and volatility of bank stock returns, and its exposure to financial derivative contracts.

The study is based on 109 publicly traded European banks over the period from 2005 to 2010. The database

contains both accounting data from Bankscope and manually collected information from the notes to financial

statements. After controlling for bank-specific characteristics, time effects and cross-country differences,

we find that banks efficiently using hedging derivatives have a lower risk and a higher value. However,

this relationship becomes less pronounced or is inversed in the post-crisis period and concerns both

trading and hedging derivatives. For systemically important banks heavily involved in derivatives market

volatility of stock returns is higher and valuations are lower.We notice however that derivatives play second

fiddle to bank risk and performance. Our findings corroborate the importance of distinction of derivatives

by the purpose of use, which becomes less obvious for investors in the post-crisis period. Our results have

important policy implications, especially in the light of the recent debate over the necessity of separation of

risky banking activities from commercial bank branches (for instance, as proposed in Liikanen report) in an

attempt to reduce systemic risk. We emphasize the need for a higher transparency of disclosures regarding

hedge accounting and harmonisation of reporting formats across EU.
