From technical perspective, an important condition for developing industrial symbiosis (IS) is the match between waste supply and demand. Such a match is hampered by lack of information among companies, i.e., demand (supply) for waste exists but firms producing (requiring) that waste are not aware of such a demand (supply). Despite online information-sharing platforms are proposed to support the creation of industrial symbiosis networks (ISNs), related environmental and economic benefits are not in-depth investigated. This paper firstly aims to fill this gap.

The aim of this paper is to propose a taxonomy of industrial symbiosis (IS) business models. Rather than to adopt a firm perspective, we take a system perspective and focus on the governance of the system made up of the firms implementing IS, being the latter considered an important factor influencing firm's competitive advantage. Four extreme IS business models are identified, characterized on the basis of two governance features: (1) need for coordination and (2) centralization of control.

Industrial symbiosis (IS) is recognized as an effective practice to support circular economy and sustainable development because it is able to enhance the technical efficiency of production processes, provided IS relationships among companies remain active over the long period. However, although it has been established that IS relationships can be vulnerable to disruptive events that reduce the willingness of companies to cooperate in IS synergies, to date few contributions to the literature focus attention on the events which lead firms to interrupt IS synergies.

This paper presents a game theoretic morphological analysis of the strategic interactions between environmental enforcement authorities and polluting firms. The models explore the role of discretion that such authorities enjoy, either in deciding how to pursue environmental violations (investigative and prosecutorial discretion) or in judging them (judicial discretion). The purpose is to identify both the optimal

This paper addresses the problem of ranking growth episodes from a microeconomic perspective.
While most of the existing criteria, framed in the pro-poor growth tradition, are either based on anonymous
individuals or are used to identify them on the basis of their status in the initial period, this
paper proposes new criteria to evaluate growth, which are robust to the choice of the reference period
used to identify individuals. Suitable dominance conditions that can be used to rank alternative growth
