Asymmetric multivariate normal mixture GARCH

An asymmetric multivariate generalization of the recently proposed class of normal mixture GARCH models is developed. Issues of parametrization and estimation are discussed. Conditions for covariance stationarity and the existence of the fourth moment are derived, and expressions for the dynamic correlation structure of the process are provided. In an application to stock market...

Young measure flow as a model for damage

Models for hysteresis in continuum mechanics are studied that rely on a time-discretised quasi-static evolution of Young measures akin to a gradient flow. The main feature of this approach is that it allows for local, rather than global minimisation. In particular, the case of a non-coercive elastic energy density of Lennard-Jones type is investigated. The approach is used to...

Look-ahead benchmark bias in portfolio performance evaluation

Performance of investment managers is predominantly evaluated against targeted benchmarks, such as stock, bond or commodity indices. However, most professional databases
do not retain timeseries for companies that disappeared, and do not necessarily track the change of constitution in these benchmarks. Consequently, standard tests of performance suffer from the “look-ahead...

Cash sub-additive risk measures and interest rate ambiguity

A new class of risk measures called cash sub-additive risk measures is introduced to assess the risk of future financial, nonfinancial and insurance positions. The debated cash additive axiom is relaxed into the cash sub-additive axiom to preserve the original difference between the numeraire of the current reserve amounts and future positions. Consequently, cash sub-additive risk...

CHICAGO: A fast and accurate method for portfolio risk calculation

This paper shows how independent component analysis can be used to estimate the generalized orthogonal GARCH model in a fraction of the time otherwise required. The proposed method is a two-step procedure, separating the estimation of the correlation structure from that of the univariate dynamics, thus facilitating the incorporation of non-Gaussian innovations distributions in a...

Assessing and improving the performance of nearly efficient unit root tests in small samples

The development of unit root tests continues unabated, with many recent contributions using techniques such as generalized least squares (GLS) detrending and recursive detrending to improve the power of the test. In this article, the relation between the seemingly disparate tests is demonstrated by algebraically nesting all of them as ratios of quadratic forms in normal variables. By...

Prospect theory and mean-variance analysis: Does it make a difference in wealth management?

We show that prospect theory is a valuable paradigm for wealth management. It describes well how investors perceive
risk and with appropriate modeling it can be made consistent with rational decision making. Moreover, it can be
represented in a simple reward-risk diagram so that the main ideas are easily communicated to clients. Finally, we
show on data from a large...

Optimality of prompt corrective action in a continuous - time model with recapitalization possibility

Prompt Corrective Action (PCA) is a system of predetermined capital/asset ratios that trigger supervisory actions by a banking regulator. Our paper addresses the optimality of this regulation system by adapting a dynamic model of entrepreneurial fi?nance to banking regulation. In a dynamic moral hazard setting, we fi?rst derive the optimal contract between the banker and the...
