Non-linear incentive equilibrium strategies for a transboundary pollution differential game

Producción CientíficaIn this paper we apply non-linear incentive strategies to sustain over time an agreement. We illustrate the use of these strategies in a linear-quadratic transboundary pollution differential game. The incentive strategies are constructed in such a way that in the long run the pollution stock (the state variable) is close to the steady state of the pollution stock under the cooperative mode of play. The non-linear incentive functions depend on the emission rates (control variables) of both players and on the current value of the pollution stock. The credibility of the incentive equilibrium strategies is analyzed and the performance of open-loop and feedback incentive strategies is compared in their role of helping to sustain an agreement over time. We present numerical experiments to illustrate the results.This research is partially supported by MINECO under projects MTM2016-78995-P (AEI) and ECO2014-52343-P and ECO2017-82227-P (AEI) and by Junta de Castilla y León VA024P17 and VA105G18 co-financed by FEDER funds (EU

Household Models: An Historical Perspective

This paper is a survey of the literature on theoretical models of the household, paying particular attention to some of the earlier contributions, and using them to place the current state of the theory in perspective. One of its aims is to suggest that the literature’s neglect of Samuelson’s proposal, that households can be modelled as if they maximised a form of social welfare function, was a mistake. However, the idea following directly from the Nash bargaining models, that the household’s preference ordering over the utility profiles of its members depends on exogenous variables, in particular wage rates and non-wage incomes, is an important one. Combined with Samuelson’s proposal, it can be made the basis for a general approach to modelling household decision taking, flexible enough to encompass non-cooperative behaviour and Pareto inefficiencies arising out of the inevitable incompleteness and unenforceability of domestic agreements. We also point out the importance of household production and some of the implications of its neglect in modelling households. Above all, the aim is to provide a deeper understanding of the current theoretical literature on household economics by means of a survey of its history.household behavior, family economics, household welfare, time allocation, labor supply, household production, child care, gender, discrimination, cooperative models, non-cooperative models, trade models, microeconomic history

Non-centralized Control for Flow-based Distribution Networks: A Game-theoretical Insight

This paper solves a data-driven control problem for a flow-based distribution network with two objectives: a resource allocation and a fair distribution of costs. These objectives represent both cooperation and competition directions. It is proposed a solution that combines either a centralized or distributed cooperative game approach using the Shapley value to determine a proper partitioning of the system and a fair communication cost distribution. On the other hand, a decentralized noncooperative game approach computing the Nash equilibrium is used to achieve the control objective of the resource allocation under a non-complete information topology. Furthermore, an invariant-set property is presented and the closed-loop system stability is analyzed for the non cooperative game approach. Another contribution regarding the cooperative game approach is an alternative way to compute the Shapley value for the proposed specific characteristic function. Unlike the classical cooperative-games approach, which has a limited application due to the combinatorial explosion issues, the alternative method allows calculating the Shapley value in polynomial time and hence can be applied to large-scale problems.Generalitat de Catalunya FI 2014Ministerio de Ciencia y Educación DPI2016-76493-C3-3-RMinisterio de Ciencia y Educación DPI2008-05818Proyecto europeo FP7-ICT DYMASO

Integrated game-theory modelling for multi enterprise-wide coordination and collaboration under uncertain competitive environment

In this work, an integrated Game Theory (GT) approach is developed for the coordination of multi-enterprise Supply Chains (SCs) in a competitive uncertain environment. The conflicting goals of the different participants are solved through coordination contracts using a non-cooperative non-zero-sum Stackelberg game under the leadership of the manufacturer. The Stackelberg payoff matrix is built under the nominal conditions, and then evaluated under different probable uncertain scenarios using a Monte-Carlo simulation. The competition between the Stackelberg game players and the third parties is solved through a Nash Equilibrium game. A novel way to analyze the game outcome is proposed based on a win–win Stackelberg set of “Pareto-frontiers”. The benefits of the resulting MINLP tactical models are illustrated by a case study with different vendors around a client SC. The results show that the coordinated decisions lead to higher expected payoffs compared to the standalone case, while also leading to uncertainty reduction.Peer ReviewedPostprint (author's final draft

Individual Decisions and Household Demand for Consumption And Leisure

The standard microeconomic assumption of a household utility function raises two theoretical problems: it contradicts methodological individualism and it ignores economic phenomena like income and consumption sharing, division of labour, externalities and altruism within a household. This paper reviews two approaches, aggregation theory and more recent non-unitary models, to compare the different properties that household consumption and leisure demands have to satisfy in the two basic contexts. The paper also discusses some recent empirical evidence which seems to encourage further investigation in the non-unitary framework.consumption, labour supply, intra- household allocation

Tradable Permits vs Ecological Dumping

In this paper we examine an alternative policy scenario, where governments allow polluting firms to trade permits in a strategic environmental policy model. We demonstrate, among other things, that with no market power in the permits market, governments of the exporting firms do not have an incentive to under-regulate pollution in order to become more competitive. This strategic effect is reversed and leads to a welfare level closer to the cooperative one and strictly higher to that when permits are non-tradable. Allowing for market power in the permits market, the incentive to under-regulate pollution re-appears regardless of whether permits are tradable or not. With tradable permits, however, the incentive to under-regulate pollution is comparatively weaker relative to the case of non-tradable permits. This entails potential benefits for the exporting firms and countries since the prisoners’ dilemma is moderated.Strategic Environmental Policy, Tradable Permits, Race to the top
