    Subsidizing a New Technology: An Impulse Stackelberg Game Approach

    Oct 31, 2024 11:00 AM — 12:00 PM (Montreal SUMMER time)

    Zoom webinar link

    Governments are motivated to subsidize profit-driven firms that manufacture zero-emission vehicles to ensure they become price-competitive. This paper introduces a dynamic Stackelberg game to determine the government’s optimal subsidy strategy for zero-emission vehicles, taking into account the pricing decisions of a profit-maximizing firm. While firms have the flexibility to change prices continuously, subsidies are adjusted at specific time intervals. This is captured in our game formulation by using impulse controls for discrete-time interventions. We provide a verification theorem to characterize the Feedback Stackelberg equilibrium and illustrate our results with numerical experiments. (with Georges Zaccour)

    A Stackelberg game approach to evaluate the effectiveness of cap-and-trade regulation under disruption

    Nov 7, 2024   11:00 AM — 12:00 PM

    Seminar in hybrid format at GERAD room 4488 or Zoom

    This study explores the impact of cap-and-trade regulations on the performance of dual-channel green supply chains in the presence of disruptions. It examines the interplay between pricing and greening strategies under cap-and-trade conditions and varying market demand disruptions. The model employs a Stackelberg game framework involving an eco-friendly product manufacturer and a retailer, applicable to centralized and decentralized systems. Results show that a dynamic cap-and-trade system can provide the needed flexibility to adjust emission allowances in real time, and dynamic regulatory frameworks should be supported to balance emission management with supply chain profitability.

    A general tractable differential game framework with an application to north-south climate policy

    Oct 24, 2024   11:00 AM — 12:00 PM

    We introduce a differential game framework that retains tractability while not relying on commonly used restrictive linearity assumptions. Our frame is particularly suitable for analytical study the implication of a large set of heterogeneity traits across players. As an illustration, we employ it to derive new insights on climate-related policy. Our framework allows us to characterize emissions, consumption, and welfare across different equilibrium outcomes by comparing the Nash and Stackelberg equilibria of a game capturing climate negotiations between “global north” and a “global south.” We draw various comparisons between such outcomes and the efficient frontier. We find that both the global north and south underinvest in abatement. Stackelberg leadership by the global north reduces emissions and increases welfare over the Nash outcome, although emissions remain far from the optimum. Asymmetric vulnerability to climate change leads to a reversal in emissions, where the less vulnerable country emits more. We employ robust control to study how deep uncertainty affects outcomes.
