In this paper, we compared the models for selecting the optimal portfolio based on different risk measures to identify the periods in which some of the risk measures dominated over others. For decades, the best known return-risk model has been Markowitz's mean-variance model. Based on the...

Purpose - The purpose of this paper is to study the Hölder calmness of solutions to equilibrium problems and apply it to economics. Design/methodology/approach - The authors obtain the Hölder calmness by using an effective approach. More precisely, under the key assumption of strong convexity,...

This paper aims to identify an optimal investment strategy in cases of high-intensity R&D private micro entities. A game theory matrix is constructed using publicly available empirical data extracted from the financial statements of an R&D-intensive private micro-entity. The game theory matrix...

In this article, we extend the application of cooperative game theory to the so-called low-risk puzzle. Specifically, we apply concepts that consider hierarchies on the assets in the allocation of portfolio risk. These hierarchies have not previously been considered in portfolio risk allocation...

The problem of coordination between policymakers seems to have created fundamental problems related to economic and social costs, targeted inflation, potential growth, and a high budget deficit. To resolve these problems in this framework, it is important to see the results of the interaction...

We consider a game-theoretic model of undocumented immigration with the aim of emphasizing the strategic interaction between the different forces affecting the issue. Specifically, we analyze the strategic interaction between firms in the destination country, native labor, the elected officials...

Through a structured literature review and an exploratory factor analysis, this thesis presents a conceptual framework with 6 key factors composed of 19 indicators, including government, consumer, company, product, operation and partnership, which affecting the development of e-logistics in...

This study explores the dynamics of international strategic learning alliances through the lens of game theory, incorporating complexity and cooperative game theories to develop a model of organizational evolution. Using simulations and network resources, we examine 1200 cases to assess the...

The focus of this review is the long and broad history of attacker-defender games as a foundation for the narrower and shorter history of cyber security. The purpose is to illustrate the role of game theory in cyber security and which areas have received attention and to indicate future research...
