Turnpike Property and Convergence Rate for an Investment Model with General Utility Functions

open access: yes, 2014
In this paper we aim to address two questions faced by a long-term investor with a power-type utility at high levels of wealth: one is whether the turnpike property still holds for a general utility that is not necessarily differentiable or strictly ...

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.

Image Restoration via the Integration of Optimal Control Techniques and the Hamilton–Jacobi–Bellman Equation

open access: yesMathematics
In this paper, we propose a novel image restoration framework that integrates optimal control techniques with the Hamilton–Jacobi–Bellman (HJB) equation.

Optimal control in an inventory management problem considering replenishment lead time based upon a non-diffusive stochastic differential equation

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2019
An inventory management problem is theoretically discussed for a factory having effects of lead times in replenishing the inventory, where it stocks materials used for its products.

Mitigating the Curse of Dimensionality: Sparse Grid Characteristics Method for Optimal Feedback Control and HJB Equations [PDF]

open access: yes, 2016
We address finding the semi-global solutions to optimal feedback control and the Hamilton--Jacobi--Bellman (HJB) equation. Using the solution of an HJB equation, a feedback optimal control law can be implemented in real-time with minimum computational ...

A New Scheme for Discrete HJB Equations

open access: yesApplied Mathematics, 2014
In this paper we propose a relaxation scheme for solving discrete HJB equations based on scheme II [1] of Lions and Mercier. The convergence of the new scheme has been established. Numerical example shows that the scheme is efficient.

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

Well-posedness and regularity of the Cauchy problem for nonlinear fractional in time and space equations

open access: yes, 2014
The purpose is to study the Cauchy problem for non-linear in time and space pseudo-differential equations. These include the fractional in time versions of HJB equations governing the controlled scaled CTRW.

Satellite Data Trace Seasonal Freshwater Dispersion in Hudson and James Bays

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Freshwater dispersal controls stratification, circulation, and biogeochemical processes in Hudson and James Bay (HJB); however, limited field observations hinder understanding of how different freshwater types drive change. This study uses Aqua‐Moderate Resolution Imaging Spectroradiometer and Soil Moisture and Ocean Salinity‐Microwave Imaging

Contingency discrimination training and resurgence: Effects of reduced extinction session durations

open access: yesJournal of the Experimental Analysis of Behavior, Volume 125, Issue 1, January 2026.
Abstract Resurgence is an increase in a suppressed target behavior following a worsening of conditions for a more recently reinforced alternative behavior. Prior research shows that exposure to equal‐duration sessions of alternative reinforcement availability versus unavailability during treatment (i.e., contingency discrimination training; CDT ...
