We study the optimal loan securitization policy of a commercial bank which is mainly engaged in lending activities. For this we propose a stylized dynamic model which contains the main features affecting the securitization decision. In line with reality we assume that there are non-negligible...

The aim of this paper is to provide a modeling of capital transfer between a portfolio consisted by two assets. For this purpose we use the Arrhenius Equation, which is a modeling tool for the specific modeling. We provide a stochastic differential equation of the Arrhenuis equation. We consider...

Most finance textbooks talk about the benefits of conducting sensitivity and/or Monte Carlo simulation analyses in financial modeling, but mostly limit coverage to commenting on these techniques in passing. This is particularly true when it comes to simulation analysis, which typically requires...

This paper introduces a formulation of the optimal network compression problem for financial systems. This general formulation is presented for different levels of network compression or rerouting allowed from the initial inter-bank network. We prove that this problem is, generically, NP-hard....

One of the key challenges implied by the upcoming regulatory framework for market risk, known as FRTB, is the PL attribution (PLA) tests. PLA tests constitute a major innovation in the way risk engine and models are assessed for effectiveness and accuracy (on both pricing and risk factors...

In this paper we outline the Lagrangian constrained optimization method to solve complex problems subject to constraints. Firstly we summarize the Lagrangian constrained optimization routine. Secondly we outline a detailed implementation strategy. Thirdly and finally we provide example and solve...

The algorithm for optimization of a credit portfolio has not been fully demonstrated. This paper fills the gap in the literature by presenting a general approach for optimizing a credit portfolio by minimizing the default risk of the entire portfolio. Default risk is measured with quadratic...
