Evolutionary Dynamics in Heterogeneous Oligopolies for the Exploitation of Renewable Natural Resources (2023)
Journal Article
Bischi, G. I., & Sbragia, L. (2023). Evolutionary Dynamics in Heterogeneous Oligopolies for the Exploitation of Renewable Natural Resources. Rivista internazionale di scienze sociali, 2023(1), 35-64. https://doi.org/10.26350/000518_000109

In this paper we provide an overview of some dynamic oligopoly models proposed in the literature to describe the exploitation of a common pool renewable natural resource (e.g. fisheries) when agents can switch between different harvesting strategies....

Self-image and the Stability of International Environmental Agreements (2023)
Journal Article
Breton, M., & Sbragia, L. (2023). Self-image and the Stability of International Environmental Agreements. Ecological Economics, 211, Article 107869. https://doi.org/10.1016/j.ecolecon.2023.107869

In this paper we examine the stability of international environmental agreements about a (common) emissions target. By signing the agreement, the parties develop a sense of responsibility to the commitment made, gaining a self-image that contributes...

Intra-brand competition in a differentiated oligopoly (2020)
Journal Article
Breton, M., & Sbragia, L. (2020). Intra-brand competition in a differentiated oligopoly. Journal of Economics, 132(1), 1-40. https://doi.org/10.1007/s00712-020-00712-w

In this paper we consider a differentiated oligopoly with two product varieties that are supplied by two groups of firms. After computing the Cournot solution of the game, we study its sensitivity to different sources of competition, namely the degre...

The Impact of Adaptation on the Stability of International Environmental Agreements (2019)
Journal Article
Breton, M., & Sbragia, L. (2019). The Impact of Adaptation on the Stability of International Environmental Agreements. Environmental and Resource Economics, 74(2), 697-725. https://doi.org/10.1007/s10640-019-00341-y

We examine the stability of international environmental agreements that include clauses pertaining to both adaptation and mitigation measures. We assume that adaptation requires a prior irreversible investment and presents the characteristics of a pr...

The impact of adaptation on the stability of international environmental agreements (2017)
Preprint / Working Paper
Breton, M., & Sbragia, L. (2017). The impact of adaptation on the stability of international environmental agreements

We examine the stability of international environmental agreements when they include both adaptation and mitigation policies. We assume that adaptation requires a prior irreversible investment and presents the characteristics of a private good by red...

Adaptation to Climate Change: Commitment and Timing Issues (2016)
Journal Article
Breton, M., & Sbragia, L. (2017). Adaptation to Climate Change: Commitment and Timing Issues. Environmental and Resource Economics, 68(4), 975-995. https://doi.org/10.1007/s10640-016-0056-9

We study the impact of timing and commitment on adaptation and mitigation policies in the context of international environmental problems. Adaptation policies present the characteristics of a private good and may require a prior investment, while mit... Read More about Adaptation to Climate Change: Commitment and Timing Issues.

Dynamic Modeling in Renewable Resource Exploitation (2016)
Book Chapter
Lamantia, F., Radi, D., & Sbragia, L. (2016). Dynamic Modeling in Renewable Resource Exploitation. In G. I. Bischi, A. Panchuk, & D. Radi (Eds.), Qualitative theory of dynamical systems, tools and applications for economic modelling : lectures given at the COST Training School on new economic complex geography at Urbino, Italy, 17-19 September 2015 (257-289). Springer Verlag. https://doi.org/10.1007/978-3-319-33276-5_5

This chapter reviews some fundamental models related to the exploitation of a renewable resource, an important topic when dealing with regional economics. The chapter starts by considering the growth models of an unexploited population and then intro... Read More about Dynamic Modeling in Renewable Resource Exploitation.

Adaptation to climate change: Commitment and timing issues (2016)
Preprint / Working Paper
Breton, M., & Sbragia, L. (2016). Adaptation to climate change: Commitment and timing issues

We study the impact of timing and commitment on adaptation and mitigation policies in the context of international environmental problems. Adaptation policies present the characteristics of a private good and may require a prior investment, while mit... Read More about Adaptation to climate change: Commitment and timing issues.

Strategic interaction and imitation dynamics in patch differentiated exploitation of fisheries (2009)
Journal Article
Bischi, G., Lamantia, F., & Sbragia, L. (2009). Strategic interaction and imitation dynamics in patch differentiated exploitation of fisheries. Ecological Complexity, 6(3), 353-362. https://doi.org/10.1016/j.ecocom.2009.03.004

In this paper we propose a discrete-time dynamic model for studying the time evolution of fish stocks in an aquatic environment divided into two adjacent patches, one characterized by an imposed constant fishing effort and another one where fishermen...

A model of financial market dynamics with heterogeneous beliefs and state-dependent confidence (2008)
Journal Article
Chiarella, C., Dieci, R., Gardini, L., & Sbragia, L. (2008). A model of financial market dynamics with heterogeneous beliefs and state-dependent confidence. Computational Economics, 32(1/2), 55-72. https://doi.org/10.1007/s10614-008-9131-9

In a simple model of financial market dynamics, we allow the price of a risky security to be set by a market maker depending on the excess demand of heterogeneous interacting traders, fundamentalists and chartists, who place their orders based upon d...

Learning the Demand Function in a Repeated Cournot Oligopoly Game (2008)
Journal Article
Bischi, G., Sbragia, L., & Szidarovszky, F. (2008). Learning the Demand Function in a Repeated Cournot Oligopoly Game. International Journal of Systems Science, 39(4), 403-419. https://doi.org/10.1080/00207720701792131

In this article, single product Cournot oligopolies are considered, where the demand and cost functions are linear. While cost functions are completely known by all firms, they only partially know the demand function, as they misspecify the slope. At...

Oligopoly Games with Local Monopolistic Approximation. (2007)
Journal Article
Bischi, G., Naimzada, A., & Sbragia, L. (2007). Oligopoly Games with Local Monopolistic Approximation. Journal of Economic Behavior and Organization, 62(3), 371-388. https://doi.org/10.1016/j.jebo.2005.08.006

We propose an oligopoly game where quantity setting firms have incomplete information about the demand function. At each time step they solve a profit maximization problem assuming a linear demand function and ignoring the effects of the competitors’...
