Título: Cooperative and Non-Cooperative Strategies in Product Warranty
Pricing: A Hierarchical Game Approach Palestrante: Dr. Henrique Santos (Pós
doutorando, UFPE) Abstract
This paper analyzes the pricing dynamics of product warranties by
developing a three-player hierarchical game model involving a manufacturer,
an independent service agent, and a consumer. The model provides a scenario
where the manufacturer and the agent form a coalition to coordinate pricing
strategies, while interacting non-cooperatively with the consumer. In this
framework, the manufacturer sets the product’s sale price, including the
base warranty, while the agent determines the price of extended maintenance
services. The key contribution is the application of the Shapley value to
equitably distribute the coalition’s profits based on each member’s
contribution—a novel approach in the warranty pricing literature. We detail
the characteristic functions that define the coalition’s structure and
present computer simulations to estimate the expected costs associated with
maintenance services. A comprehensive sensitivity analysis is applied to
report how changes in parameters influence equilibrium strategies and
players’ payoffs. The results provide strategic insights into how
manufacturers and agents can coordinate to optimize pricing, capture
consumer surplus, and improve decision-making in warranty service markets.
