> 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.
> Keywords: hierarchical game theory; product warranty; pricing strategy;
