We quantify and endogenize the model risk associated with quantile estimates using a maximum entropy distribution (MED) as benchmark. Moment-based MEDs cannot have heavy tails, however generalized beta generated distributions have attractive properties for popular applications of quantiles....

With a sample of twelve US bond indices spanning different maturities, credit ratings and industry sectors, we investigate the impact of new bank capital regulation for trading portfolios introduced by Basel III. Specifically, we estimate the new capital requirements for (a) liquidity risk and...

By using Moody's historical corporate default histories we explore the implications of scenarios based on the Great Depression for banks' economic capital and for existing and proposed regulatory capital requirements. By assuming different degrees of portfolio illiquidity, we then investigate...

Basel II rules allow qualified banks to assess the risk in their portfolio of credit exposures with a methodology based on the informational content of credit ratings and two crucial assumptions: (1) the credit risk of individual exposures is driven by one systematic risk factor only and (2) the...

The new bank capital regulation commonly known as Basel II includes a internal rating based approach (IRB) to measuring credit risk in bank portfolios. The IRB relies on the assumptions that the portfolio is fully diversified and that systematic risk is driven by one common factor. In this work...

We examine the pricing of Asian and non-Asian credit default swaps that traded during the 1997 to 1999 time period. We employ two credit risk models, Duffie and Singleton (1999) and Jarrow and Turnbull (1995). We argue that credit default swaps should have a positive economic value since credit...

Current research on financial risk management applications of econometrics centres on the accurate assessment of individual market and credit risks with relatively little theoretical or applied econometric research on other types of risk, aggregation risk, data incompleteness and optimal risk...

We view risk management as an integral part of good management. Risk management should take a balanced view of decision problems encompassing all significant risks and rewards. Operational risks are only one type of risks and therefore are only one piece in the jigsaw puzzle that only makes...

Credit spreads can be derived from the prices of securities traded in different markets. In this paper we investigate the price discovery process in single-name credit spreads obtained from bonds, credit default swaps, equities and equity options. Using a vector error correction model (VECM) of...

We analyze, in a model of occupational choice in the labour market and discrimination in the capital market, the relationship between the gender of the owner and of the top manager of a firm, access to finance, and this firm's performance. Occupational choice serves as the link from the capital...
