Anti-tax loss trafficking rules disallow the use of loss carryforwards after a change in ownership or activity (such as significant changes in turnover, employment, or the product portfolio). This restriction could threaten accumulated loss carryforwards of start-ups. Accounting for the...

Hedge Funds are often considered as a possibility for optimizing traditional portfolios due to their alternative risk factors and sources of return. But as the return distribution of hedge funds shows negative skewness and excess kurtosis, using portfolio optimization techniques, based on the...

We investigate the problem of modeling defaults of dependent credits. In the framework of the class of structural default models we study threshold models where for each credit the underling ability-to-pay process is a transformation of a Wiener processes. We propose a model for dependent...

Credit risk measurement and management become more important in all financial institutions in the light of the current financial crisis and the global recession. This particularly applies to most of the complex structured financing forms whose risk cannot be quantified with com-mon rating...

In almost every financial market crisis we can observe widening credit spreads, especially in the last years during the subprime and sovereign debt crisis. But what exactly drives the credit spread? This paper will outline static components, i.e. default risk, liquidity, risk and the relative...

This paper investigates the managing strategies of a bank's liquidity reserve in the broader context of the role of asset-liability management according to the liquidity issues of a banking organisation. Several types of liquidity are presented and how these are interconnected and how they might...

The paper models and analyses the dynamics of credit spread curves based on ratings over the period from 2004 to 2021. Using more than 1.5 million data points of individual bonds, instead of using index data, monthly asset swap spread (ASW) curves are constructed for all rating levels. The paper...

In markets with quality unobservable to buyers, third-party certification is often the only instrument to increase transparency. While both sellers and buyers have a demand for certification, its role differs fundamentally: sellers use it for signaling, buyers use it for inspection. Seller...

This paper tests for the sensitivity of R&D to financing constraints conditional on restrictions in external financing. Financing constraints of firms are identified by an exogenously calculated rating index. Restrictions in external financing are determined by (i) the specific time period...

This paper provides evidence of deliberate private-information disclosure within banks’ international business networks. Using supervisory trade-level data, we show that banks with closer ties to a target advisor in a takeover buy more stocks of the target firm prior to the deal announcement,...
