. After the global crisis of 2008-2009, the world economy entered the era of restructuring. This article focuses on the risks that a new leader will face in the process of shaping the world economy. The methods employed in the research include big data processing of continuous change and the...

Over the past years, there has been an increase in global geopolitical risk, the most recent example being the intensifying conflict between the USA and Iran. Such geopolitical risks also affect the German economy. A geopolitical shock, defined as an unexpected increase in risk, has a...

By the end of 2020, the European Central Bank (ECB) will present the results of its monetary policy strategy review. What changes are to be expected and what changes are needed? This report covers two areas of the strategy review. First, alternatives to the current definition of price stability...

This paper captures and measures the longevity risk generated by an annuity product. The longevity risk is materialized by the uncertain level of the future liability compared to the initially foretasted or expected value. Herein we compute the solvency capital (SC) of an insurer selling such a...

This paper considers the risk model perturbed by a diffusion process with a time delay in the arrival of the first two claims and takes into account dependence between claim amounts and the claim inter-occurrence times. Assuming that the time arrival of the first claim follows a generalized...

Mean-variance portfolio optimization is more popular than optimization procedures that employ downside risk measures such as the semivariance, despite the latter being more in line with the preferences of a rational investor. We describe strengths and weaknesses of semivariance and how to...

The present study aims at modelling market risk for four commodities, namely West Texas Intermediate (WTI) crude oil, natural gas, gold and corn for the period 2007-2017. To this purpose, we use Extreme Value Theory (EVT) together with a set of Conditional Auto-Regressive Logit (CARL) models to...

We discuss aspects of numerical methods for the computation of Gerber-Shiu or discounted penalty-functions in renewal risk models. We take an analytical point of view and link this function to a partial-integro-differential equation and propose a numerical method for its solution. We show weak...
