A Differential Game for Renewable Resource Extraction Asymmetric Players and Asynchronous Horizons

In this paper we study a differential game, for resource extraction of a renewable good, in which players are overlapping generations of extractors. The framework of overlapping generation allows us to consider intragenerational (players in the same generation) and intergenerational (players in different generations) game equilibrium. We consider the case in which players, even if identical, face competition in an asymmetric way. Since we consider overlapping generations, players have asynchronous horizons, in contrast with a number of studies in intertemporal exploitation of resources in which players have identical time horizons.Feedback Nash Equilibrium, resource extraction, overlapping generations, asynchronous horizon, asymmetric players.

A Stackelberg Differential Game with Overlapping Generations

We study a differential game, for the extraction of a renewable resource, in which players are overlapping generations of extractors. The framework of overlapping generation allows us to consider both intragenerational (players in the same generation) and intergenerational (players in different generations) competition. Since we consider overlapping generations, players have asynchronous horizons. We consider the case in which players, even if identical, face competition in an asymmetric way by mean of two different approaches: different costs and Leader-Follower competition. The leader-follower structure, as a consequence of the overlapping generation framework, is not fixed but depends on the time period in which each player is living in. The behaviour of the players can be of two ways: myopic or not myopic.Feedback Feedback Nash Equilibrium, resource extraction, overlapping generations, asynchronous horizon, asymmetric players, Stackelberg differential game.

A Review on Strong Interpolation Theorem for Way Below Relation

The present paper aims to introduce the principal definitions and proof of fundamental properties of the so called "Way Below" relation. We introduce an alternative proof, with respect to \cite{Scott}, of the strong interpolation theorem. The strong interpolation theorem is the theoretical result which provide computational consistency to way below relation because it guarantee the use of successive algorithm in order to find a better and better approximation of the result.continuous lattice, way-below relation, strong interpolation

Resource extraction activity: an intergenerational approach

The problem of resource extraction (both renewable and nonrenewable) can be studied by considering two important aspects: competition among extractors and intergenerational equity. In resource extraction activity actions of present generations influence the choices of future generation in an obvious way. In order to capture these features we consider a differential game in which players are overlapping generations of extractors, in this way both competition and intergenerational equity are included in the model. An important feature of this model is that, since we consider overlapping generations, players have asynchronous horizons, in contrast with a number of studies in intertemporal exploitation of resources in which players have identical time horizons. The framework of overlapping generation allows us to consider intragenerational (players in the same generation) and intergenerational (players in different generations) game equilibrium in the contest of differential games with asynchronous horizons.Feedback Nash Equilibrium, resource extraction, overlapping generations, asynchronous horizon

Encouraging pro-environmental behaviours: a review of methods and approaches. ESRI Working Paper No. 645 December 2019

Many urgent environmental problems can be mitigated with more sustainable use of resource. An acknowledgement of which is a growing interest among policy practitioners in encouraging pro-environmental behaviour change initiatives. The effect of anthropic pressure on the environment is long known and the first pro-environmental behaviour studies date back to the middle 1970s. Despite this, the scientific literature has not yet answered several questions: what are the most suitable ways to encourage behavioural changes? What are the barriers to project implementation? What are the long run effects of behavioural change projects? With this in mind, this contribution offers a review of the existing literature on behavioural change case studies and provides a categorisation of treatments and guidelines for successful project implementation. Five different approaches have been considered: education and awareness, social influence, relationship building, incentives and nudges, which have been used in experimental studies. On balance the case studies suggest that all approaches are suitable but their selection should be based on specific objectives and target population. Interestingly, the choice of the behaviour to change is rarely discussed before project implementation. This analysis also highlights that little is known on whether behaviour change projects achieve sustained pro-environmental behavioural change over time

Stripe formation in electron-doped cuprates

We investigate the formation of charge domain walls in an electron-doped extended Hubbard model for the superconducting cuprates. Within an unrestricted Hartree-Fock approach, extended by the introduction of slave-bosons to obtain a more proper treatment of strong correlations, we demonstrate the occurrence of stripes in the (1,1) and (1,-1) directions having one doped electron per stripe site. The different filling, direction and width of these electron-doped stripes with respect to those obtained in the hole-doped systems have interesting observable consequences, which are discussed.Comment: 4 pages, 2 encapsulated postscript figure

Hunting electroweakinos at future hadron colliders and direct detection experiments

We analyse the mass reach for electroweakinos at future hadron colliders and their interplay with direct detection experiments. Motivated by the LHC data, we focus on split supersymmetry models with different electroweakino spectra. We find for example that a 100 TeV collider may explore Winos up to ~ 7 TeV in low scale gauge mediation models or thermal Wino dark matter around 3 TeV in models of anomaly mediation with long-lived Winos. We show moreover how collider searches and direct detection experiments have the potential to cover large part of the parameter space even in scenarios where the lightest neutralino does not contribute to the whole dark matter relic density.Comment: 25 pages, matches version accepted by JHE
