We investigate the role of competition on the outcome of Austrian Treasury auctions. EU accession by Austria provides a natural experiment causing an exogenous increase in the number of bidders in Treasury Auctions. Difference-in-difference estimates suggest that the increased number in bidders...

To issue Treasury securities by auctions is a common method in many countries all over the world. The auction mechanisms used vary across countries. As our understanding of bidder behavior in Treasury auctions is still rather limited it is not surprising that the question which auction mechanism...

We propose a new method for the analysis of systemic stability of a banking system relying mostly on market data. We model both asset correlations and interlinkages from interbank borrowing so that our analysis gauges two major sources of systemic risk: Correlated exposures and mutual credit...

We propose a new approach to assess the financial stability of an entire banking system using standard tools from modern risk management in combination with a network model of inter-bank loans. Rather than looking at banks individually, we analyze risk at the level of the banking system as a...

I discuss a network of banks which are linked by financial obligations and cross holdings. Given an initial endowment the value of the obligations and the equity values of the banks are determined endogenously in a way consistent with the priority of debt and the limited liability of equity....

We analyze the pricing of risky income streams in a world with competitive security markets where investors are constrained by restrictions on possible portfolio holdings. We investigate how we can transfer concepts and pricing techniques from a world without frictions to such a more realistic...

We provide an empirical analysis of the network structure of the Austrian interbank market based on Austrian Central Bank (OeNB) data. The interbank market is interpreted as a network where banks are nodes and the claims and liabilities between banks define the links. This allows us to apply...

In this paper we suggest a new approach to risk assessment for banks. Rather than looking at them individually we try to undertake an analysis at the level of the banking system. Such a perspective is necessary because the complicated network of mutual credit obligations can make the actual risk...

I discuss a network of banks which are linked with each other by financial obligations and cross holdings. Given an initial endowment the value of the obligations and the equity values of the banks are determined endogenously in a way consistent with the priority of debt and the limited...
