Abstract German (English abstract is added below) Arbeitslosigkeit gilt als eines der schwerwiegendsten gesellschaftlichen Probleme unserer Zeit. Doch welche Gründe liegen, trotz der über die Jahre eingeleiteten Maßnahmen zur Bekämpfung der Arbeitslosigkeit, für die anhaltende...

In the paper model of macroeconomic turnover and its possibilities for investments modelling are shown. The model consists from four blocks: in the first the theoretical model is described. In the second the model is reflected in accordance with the requirements of system dynamics method, there...

It is generally accepted that the recent economic crisis of 2007-2010 has caused widespread economic recession in different countries. Since the ports and coastal regions are of great importance to economic infrastructure, this study examined the possible impact resulting from such a global...

In this paper we present compelling evidence from a detailed analysis of historical prepayment data to demonstrate that a mortgage cohort remembers the level of the previous mortgage rate troughs experienced by the cohort. This is a general property, observed ubiquitously, that inescapably leads...

We present an actuarial loss reserving technique that takes into account both claim counts and claim amounts. Separate (over-dispersed) Poisson models for the claim counts and the claim amounts are combined by a joint embedding into a neural network architecture. As starting point of the neural...

The Polynomial Chaos Expansion (PCE) technique recovers a finite second order random variable exploiting suitable linear combinations of orthogonal polynomials which are functions of a given stochastic quantity $\xi$, hence acting as a kind of random basis. The PCE methodology has been developed...

This paper presents a new default risk model for market risk that is consistent with the requirements put forward by the Fundamental Review of the Trading Book. In particular, the model features correlated default times and stochastic recovery rates by exploiting the observed correlation between...

We present a claims reserving technique that uses claim-specific feature and past payment information in order to estimate claims reserves for individual reported claims. We design one single neural network allowing us to estimate expected future cash flows for every individual reported claim....

We study the possibility of completing data bases of a sample of governance, diversification and value creation variables by providing a well adapted method to reconstruct the missing parts in order to obtain a complete sample to be applied for testing the ownership-structure / diversification...

This paper will outline the functionality available in the CovRegpy package for actuarial practitioners, wealth managers, fund managers, and portfolio analysts written in Python 3.7. The major contributions of CovRegpy can be found in the CovRegpy_DCC.py, CovRegpy_IFF.py, CovRegpy_RCR.py,...
