Deep equal risk pricing of financial derivatives with non-translation invariant risk measures
Carbonneau, Alexandre; Godin, Frédéric - In: Risks : open access journal 11 (2023) 8, pp. 1-27
The objective is to study the use of non-translation invariant risk measures within the equal risk pricing (ERP) methodology for the valuation of financial derivatives. The ability to move beyond the class of convex risk measures considered in several prior studies provides more flexibility...

Bubbles, blind-spots and Brexit
Fry, John; Brint, Andrew - In: Risks : open access journal 5 (2017) 3, pp. 1-15
In this paper we develop a well-established financial model to investigate whether bubbles were present in opinion polls and betting markets prior to the UK’s vote on EU membership on 23 June 2016. The importance of our contribution is threefold. Firstly, our continuous-time model allows for...

Meta-learning approaches for recovery rate prediction
Gambetti, Paolo; Roccazzella, Francesco; Vrins, Frédéric - In: Risks : open access journal 10 (2022) 6, pp. 1-29
While previous academic research highlights the potential of machine learning and big data for predicting corporate bond recovery rates, the operations management challenge is to identify the relevant predictive variables and the appropriate model. In this paper, we use meta-learning to combine...

An efficient method for pricing analysis based on neural networks
Arabyat, Yaser Ahmad; AlZubi, Ahmad Ali; Aldebei, Dyala M. - In: Risks : open access journal 10 (2022) 8, pp. 1-14
The revolution in neural networks is a significant technological shift. It has an impact on not only all aspects of production and life, but also economic research. Neural networks have not only been a significant tool for economic study in recent years, but have also become an important topic...

Forming a risk management system based on the process approach in the conditions of economic transformation
Sidorova, Elena; Kostyukhin, Yuri; Korshunova, Lyudmila; … - In: Risks : open access journal 10 (2022) 5, pp. 1-15
The economy is in a state of transformation into a new system, and it is quite realistic that economic entities will be under the influence of certain risky moments. The process of risk analysis and management should be considered by an enterprise as an integral part of enterprise management in...

Optimal structure of real estate portfolio using EVA : a stochastic Markowitz model using data from Greek real estate market
Petropoulos, Theofanis; Liapis, Konstantinos; … - In: Risks : open access journal 11 (2023) 2, pp. 1-19
The purpose of this paper is to examine the issue of portfolio optimization. Optimization consists of minimizing the risk for a given rate of return or achieving a bigger return for a given level of risk. We use historical data from the Bank of Greece to calculate the net return and the standard...

A two-account life insurance model for scenario-based valuation including event risk
Jensen, Ninna Reitzel; Schomacker, Kristian Juul - In: Risks : open access journal 3 (2015) 2, pp. 183-218
Using a two-account model with event risk, we model life insurance contracts taking into account both guaranteed and non-guaranteed payments in participating life insurance as well as in unit-linked insurance. Here, event risk is used as a generic term for life insurance events, such as death,...

Gaussian and affine approximation of stochastic diffusion models for interest and mortality rates
Christiansen, Marcus C. - In: Risks : open access journal 1 (2013) 3, pp. 81-100
In the actuarial literature, it has become common practice to model future capital returns and mortality rates stochastically in order to capture market risk and forecasting risk. Although interest rates often should and mortality rates always have to be non-negative, many authors use stochastic...
