ON THE STRUCTURE OF THE SINGULAR SET OF A PIECEWISE SMOOTH MINIMAX SOLUTION OF THE HAMILTON–JACOBI–BELLMAN EQUATION

open access: yesUral Mathematical Journal, 2016
The properties of a minimax piecewise smooth solution of the Hamilton–Jacobi–Bellman equation are studied. It is known the Rankine–Hugoniot conditions are necessary and sufficient conditions for the points of nondifferentiability (singularity) of the ...

Optimal dividends for a NatCat insurer in the presence of a climate tipping point

open access: yesCanadian Journal of Statistics, Volume 54, Issue 1, March 2026.
Abstract We study optimal dividend strategies for an insurance company facing natural catastrophe claims, anticipating the arrival of a climate tipping point after which the claim intensity and/or the claim size distribution of the underlying risks deteriorates irreversibly.

Playing with fire? A mean‐field game analysis of fire sales and systemic risk under regulatory capital constraints

open access: yesCanadian Journal of Statistics, Volume 54, Issue 1, March 2026.
Abstract We analyze the effect of regulatory capital constraints on financial stability in a large homogeneous banking system using a mean‐field game (MFG) model. Each bank holds cash and a tradable risky asset. Banks choose absolutely continuous trading rates in order to maximize expected terminal equity, with trades subject to transaction costs ...

A General Dynamic Programming Approach to the Optimal Water Storage Management for Irrigation

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 3, Page 1987-1997, February 2026.
ABSTRACT This paper proposes a dynamic programming approach targeted to solve a natural resource problem of water storage management for irrigation in an environmentally and socially sustainable way. The problem we address in our formulation, focusing on the control of water storage in tanks, is based on assumptions that are less restrictive than those

On Nonuniqueness of Solutions of Hamilton–Jacobi–Bellman Equations [PDF]

open access: yesApplied Mathematics & Optimization, 2016
An example of a nonunique solution of the Cauchy problem of Hamilton-Jacobi-Bellman (HJB) equation with surprisingly regular Hamiltonian is presented. The Hamiltonian H(t,x,p) is locally Lipschitz continuous with respect to all variables, convex in p and with linear growth with respect to p and x.

Portfolio Optimization for Pension Purposes: Literature Review

open access: yesJournal of Economic Surveys, Volume 40, Issue 1, Page 45-72, February 2026.
ABSTRACT This systematic review identifies persistent challenges and gaps in the literature on pension portfolio optimization models. We searched, selected, and critically analyzed 82 articles from three major academic databases published over the past decade to investigate the barriers to the effective implementation of these models.

On the Stochastic Optimal Control Model of the Investments of Defined Contribution (DC) Pension Funds

open access: yesJournal of Applied Sciences and Environmental Management, 2020
One of the major problems faced in the management of pension funds and plan is how to allocate and control the future flow of contribution likewise the proportion of portfolio value and investments in risky assets. In this work, optimal investment for a

On the Provision of International Public Goods in Dynamic Open Economies

open access: yesReview of International Economics, Volume 34, Issue 1, Page 198-218, February 2026.
ABSTRACT This study develops a dynamic two‐country model with an international public good, the stock of which positively affects the productivity of the private‐goods sectors in each country, and the evolution of the stock is determined by each country's voluntary contribution in the form of public investment. Two scenarios are examined: A cooperative
