Abstract:A stochastic successive approximation method is analyzed with a view to solving risk assessment problems that are reduced to a renewal integral equation and, in particular, to assessing the insolvency risk of an insurance company. Integrals in the equation are evaluated approximately, for example, by the Monte Carlo method. Iterations of the method are proved to converge uniformly with probability one. Theoretical results are illustrated by numeral computations.
“…In [31], the bankruptcy probability in a complex Poisson model was estimated by the Monte Carlo method. The papers [32][33][34] consider a risk process with arrival of claims in an insurance company, described by the general process of restoration and deterministic nonlinear monotonically increasing intensity of arrival of preiums. An algorithm is presented to construct successive approximations for nonruin probability.…”

A general mathematical concept is proposed to describe banking operation. To this end, a reference model of banking operation is introduced, which describes the evolution of capital by a Markov process. The ruin probability in the reference model that majorizes the bankruptcy probability of bank in the proposed model is estimated. The value of the initial bank capital such that the bank can operate for infinite time with a sufficiently small ruin probability is indicated.
