<p>This paper explores an effective pricing strategy for new and remanufactured short-lived products, such as smartphones and laptops, where two generations of products coexist. The existing literature argues that remanufacturing short-lived products can benefit the environment and the company’s profits, but it creates a complex market with two generations of new and remanufactured products, leading to pricing complexities. To this end, the study develops a model that factors in different product generations, accounting for time-dependent and price-sensitive demand. The closed-loop supply chain considered in the study includes a retailer, a collector, and a manufacturer (acting as a remanufacturer). The study models and evaluates two scenarios: optimizing profit in a coordinated and an uncoordinated supply chain setting. The results yield the most favorable pricing conditions for different sales horizons, based on the fluctuating rates of change in the demand for new and remanufactured products.</p>
