In the development of traditional supply-chain finance, information asymmetry all parties in supply chain has become primary problem hindering its development. Blockchain technology is an effective method to solve silos. Based on differential game theory, this paper constructs a model financial information-sharing behavior based blockchain technology. Three scenarios independent decision, cost-...

In this paper we consider a class of hybrid stochastic games with the piecewise openloop information structure. These games are indexed over a parameter ε which represents the time scale ratio between the stochastic (jump process) and the deterministic (differential state equation) parts of the dynamical system. We study the limit behavior of Nash equilibrium solutions to the hybrid stochastic ...

Stochastic evolutionary game dynamics in hierarchy are very popular in economics and in management sciences. This study extends the model of stochastic evolutionary game dynamics. This paper highlights hierarchy selection model and we show that the hierarchy selection games are more stable without structures in this paper. Furthermore, an example in industrial organization is given to rationall...

This paper considers a class of mean field linear-quadratic-Gaussian (LQG) games with model uncertainty. The drift term in the dynamics of the agents contains a common unknown function. We take a robust optimization approach where a representative agent in the limiting model views the drift uncertainty as an adversarial player. By including the mean field dynamics in an augmented state space, w...

The following topics are important teaching operation research: games theory, decision theory, utility theory, queuing theory, scheduling theory, discrete optimization. These topics are illustrated and the connection with global optimization is shown considering the following mathematical models: competition model with fixed resource prices, Nash equilibrium, competition model with free resourc...

This paper studies the backward-forward linear-quadratic-Gaussian (LQG) games with major and minor agents (players). The state of major agent follows a linear backward stochastic differential equation (BSDE) and the states of minor agents are governed by linear forward stochastic differential equations (SDEs). The major agent is dominating as its state enters those of minor agents. On the other...

PURPOSE To test the effects of employer subsidies on employee enrollment, attendance, and weight loss in a nationally available weight management program. DESIGN A randomized trial tested the impact of employer subsidy: 100%; 80%, 50%, and a hybrid 50% subsidy that could become a 100% subsidy by attaining attendance targets. TRIAL REGISTRATION NCT01756066. SETTING AND PARTICIPANTS Twenty ...

This article deals with a two-player zero-sum differential game with infinitely many initial positions and without Isaacs condition. The structure of information is asymmetric: The first player has a private information on the initial position while the second player knows only a probability distribution on the initial position. In the present model, we face two difficulties: First, the incompl...
