We develop a dynamic multivariate default model for a portfolio of credit-risky assets in which default times are modelled as random variables with possibly different marginal distributions, and Lévy subordinators are used to model the dependence among default times. In particular, we define a...

Bankruptcy is a menacing situation, which the investors, businesses, and the economy are afraid of, due to its adverse effects. Prediction of bankruptcy can help the investors and businesses in formulating their strategies in order to improve their profits or at least avoid losses. Researchers...

The research focuses on the financial turmoil, pursuing different methods to foretell such turmoil. Besides, the methods are undertaken from (McCulloch and Pitts 1943) and ended till (Hosaka 2019). The evidence from such a comprehensive analysis pointed to the use of various ratios using...

John Maynard Keynes war ein Ökonom, der stets zwischen der Welt der Theorien und der Realität pendelte, er prüfte und verwarf theoretische Annahmen aufgrund seiner Beobachtungen, die er wiederum als Ausgangspunkte für die Entwicklung neuer Theorien nutzte. Gleichzeitig betrieb er als...

We define two measures: the Model Performance Ratio (MPR), which ranks asset pricing models based on their ability to price random portfolios, and the Rate of Market Efficiency (RME), which measures market efficiency assuming the best pricing model (largest MPR). We find that: (i) market...

In this primer, we review the classical methods for assessing the performance of a financial portfolio. The analysis relies on benchmarking the return on the portfolio with that of a peer group. We define and discuss the pros and cons of four performance metrics that are theoretically consistent...

The duration of a bond approximately measures the interest rate risk caused by parallel shifts of the yield curve. This paper uses a generalization of the duration suggested by Diebold et al. (2006a), that takes the variations of the level, the slope and the curvature of the yield curve into...
