The pattern of financial linkages is important in many areas of banking and finance. Yet bilateral linkages are often unknown, and maximum entropy serves as the leading method for estimating unobserved counterparty exposures. This paper proposes an efficient alternative that combines information-theoretic arguments with economic incentives to produce more(More)
Multiple structural change tests by Bei and Perron (1998) are applied to the regression by Demetrescu, Kuzin and Hassler (2008) in order to detect breaks in the order of fractional integration. With this instrument we tackle time-varying inflation persistence as an important issue for monetary policy. We determine not only the location and significance of(More)
There is growing consensus that the conduct of monetary policy can have an impact on stability through the risk-taking incentives of banks. Falling interest rates might induce a “search for yield” and generate incentives to invest into risky activities. This paper provides evidence on the link between monetary policy, commercial property prices, and bank(More)
This paper analyses information from survey data collected in the framework of the Eurosystem’s Wage Dynamics Network (WDN) on patterns of firm-level adjustment to shocks. We document that the relative intensity and the character of price vs. cost and wage vs. employment adjustments in response to cost-push shocks depend – in theoretically sensible ways –(More)
Discussion Papers represent the authors' personal opinions and do not necessarily reflect the views of the Deutsche Bundesbank or its staff. Credit default swaps (CDSs) are financial derivatives that are designed to transfer credit risk between banks, hedge funds or asset managers in a simple way: The buyer of the CDS is insured by the seller against the(More)
Distinguishing pure supply effects from other determinants of price and quantity in the market for loans is a notoriously difficult problem. Using German data, we employ Bayesian vector autoregressive models with sign restrictions on the impulse response functions in order to enquire the role of loan supply and monetary policy shocks for the dynamics of(More)
This study analyzes the impact of bank relationships on a firm’s cost of debt. We focus on relationships with the main bank. We find that a firm’s cost of debt decreases with relationship strength, proxied by the share of bank debt provided by the main lender, but rises with relationship length. While the increase over time is weak on average,(More)
