In general, the properties of the conditional distribution of multiple period returns do not follow easily from the one-period data generating process. This renders computation of Value-at-Risk and Expected Shortfall for multiple period returns a non-trivial task. In this paper we consider some...

In this note it is argued that the estimation error in Value-at-Risk predictors gives rise to underestimation of portfolio risk. We propose a simple correction and find in an empirical illustration that it is economically relevant.

In the estimation of risk measures such as Value at Risk and Expected shortfall relatively short estimation windows are typically used rendering the estimation error a possibly non-negligible component. In this paper we build upon previous results for the Value at Risk and discuss how the...

ENGLISH ABSTRACT: The objective of almost all firms should be to maximise the wealth of shareholders.To achieve this goal, firms should use an optimal combination of debt and equity,which will consequently result in the lowest weighted average cost of capital. Firmstherefore need to determine...

This study aims to investigate whether the phenomena found by Shnoll et al. when applying histogrampattern analysis techniques to stochastic processes from chemistry and physics are also present infinancial time series, particularly exchange rate and index data. The phenomena are related to...

Universities manage their administrative and financial operations traditionally by meansof cost centres in the form of faculties, departments and divisions. In these cost centresfinancial performance is purely measured by comparing actual expenses with drawn upbudgets. During performance...

This paper studies the impact of news announcements on trade durations in stocks on the Stockholm Stock Exchange. The news are categorized into four groups and the impact on the time between transactions is studied. Times before, during and after the news release are considered. Econometrically,...
