Geometric optimisation algorithms are developed that efficiently find the nearest low-rank correlation matrix. We show, in numerical tests, that our methods compare favourably to the existing methods in the literature. The connection with the Lagrange multiplier method is established, along with...

This paper decomposes the overall market beta of common stocks into four parts reflecting uncertainty related to the long-run dynamics of stock- specific and market-wide cash flows and discount rates. We employ a discrete time version of Merton’s Intertemporal CAPM to test whether these four...

In financial markets, not only prices and returns can be considered as random variables, but also the waiting time between two transactions varies randomly. In the following, we analyse the statistical properties of General Electric stock prices, traded at NYSE, in October 1999. These properties...

In dit artikel wordt ingegaan op het statistisch kwantificeren van valutarisico’s met behulp van meervoudige regressie-analyse. Centraal punt van deze methode is dat, teneinde een integrale kwantificering van valutarisico’s te bereiken, zowel het translatierisico als het economisch...

In the product economy there is no debate as to whether the market price is the 'real' price, but instead is described as being the 'real' price. This approach has not been continued into the securities market because it is impossible to apply existing theoretical pricing mechanisms. Supply and...

We propose and examine a simple model for credit migration and spread curves of a single firm both under the real-world and the risk-neutral measure. This model is a hybrid of a structural and a reduced-form model. Default is triggered either by successive downgradings of the firm or an...

Over the last two decades MENA countries as much of the developing countries have experienced a wave of liberalization of financial sector. The purpose of this paper is three fold: to review the literature on the rationale for financial repression, examining why governments adopt financial...

This paper analyzes risk premia and volatility transmission across the stock and bond markets within an expected return beta representation of the conditional capital asset pricing model. Time variation in the market price of risk is characterized by a two state Markov regime switching process,...
