In this paper, a general model of non-cooperating agents exploiting a renewable resource is considered, and it is shown that there exists a continuum of Markov-perfect Nash equilibria (MPNE).Abstract:
A general model of non-cooperating agents exploiting a renewable resource is considered. Assuming that the resource is sufficiently productive we prove that there exists a continuum of Markov-perfect Nash equilibria (MPNE). Although these equilibria lead to over-exploitation one can approximate the efficient solution by MPNE both in the state space and the payoff space. Furthermore, we derive a necessary and sufficient condition for maximal exploitation of the resource to qualify as a MPNE. This condition is satisfied if there are sufficiently many players, or if the players are sufficiently impatient, or if the capacity of each player is sufficiently high.read more

TL;DR: In this paper, a dynamic model of private provision of public bads allowing investments in technologies is developed and the analysis is tractable and the MPE unique, and the framework is used to derive optimal incomplete contracts in a dynamic setting.

Feedback Equilibria in a Dynamic Renewable Resource Oligopoly: Pre-Emption, Voracity and Exhaustion
Luca Lambertini,Andrea Mantovani +1 more
TL;DR: In this paper, the authors extend the model to describe a differential oligopoly game of resource extraction under static, linear feedback and nonlinear feedback strategies, generalizing the result that steady state feedback outputs are lower than monopoly and static oligopoly equilibrium outputs for any number of firms.

Climate Contracts: A Game of Emissions, Investments, Negotiations, and Renegotiations
TL;DR: In this article, the authors present a dynamic game where players can contribute to a public bad, invest in technologies, and write incomplete contracts, and the analysis is tractable and the symmetric Markov perfect equilibrium unique.

Poverty, Non-pecuniary Value of Employment, and Natural Resource Extinction
Y. Hossein Farzin,Ken-Ichi Akao +1 more
TL;DR: In this paper, the authors assume that people value employment not only to earn income to satisfy their consumption needs but also as a means of community/social involvement that provides socio-psychological (non-pecuniary) benefits.

Optimal Growth with a Convex-Concave Production Function
TL;DR: In this article, the authors consider a one-sector dynamic model of an economy with a convex-concave production function and apply the maximum principle in Arrow's form, which is extremely useful for the analysis of the economic processes.

Oligopoly extraction of a common property natural resource: The importance of the period of commitment in dynamic games
TL;DR: In this article, economic competition over time is modeled as a dynamic game, and the issue is the appropriate formulation of the players' strategy spaces, which is a methodological issue when modeling economic competition as a non-cooperative game.
