Abstract This study aims to examine the relationship between bank performance and environmental performance—measured by the Environmental Pillar score—while accounting for shifts in bank performance profiles. The study focuses on the top institutions with high scores on the Environmental Pillar of ESG ratings, questioning whether their environmental performance increases financial performance. Th…

Abstract Recent years have shown continuous progress in nanoscale assembly with the development of affordable large-scale manufacturing technologies. Modular robotics and, especially, the programmable matter is one of the emanations of this evolution, which consists of a set of identical modular robots capable of reconfiguring into any shape. However, the success of such a technology depends on t…

This paper presents a novel approach to conducting environmental and social risk assessments associated with financing renewable energy projects. Risks such as community opposition, regulatory delays, and ecological damage can significantly impact both project viability and investment decisions. The aim is to provide a tool that enhances decision-making in the face of the uncertainty associated w…

Abstract When the number of Decision-Making Units (DMUs) is not large enough compared to the total number of input parameters and outputs, traditional Data Envelopment Analysis (DEA) and Network Data Envelopment Analysis (NDEA) models often produce solutions that identify many DMUs as efficient, in addition to obtaining unrealistic weight distributions. In fact, this poor discrimination power and…

The classical Myerson value for network games assigns payoffs to the players in a network based on their productivity in it. This often results in an unequal distribution of the resources generated by the players in the network. However, when link formation is costly but essential for generating resources in the network, one way of keeping the network stable is to incentivize those lesser-paid pl…
