活动简介：

Previously, firms adopt a product-based model by selling drip irrigation systems to farmers and letting farmers operate them. However, farmers do not have the knowledge to efficiently operate drip irrigation systems. Recently, firms have started to provide solutions for farmers by letting the firm's professional technicians operate drip irrigation systems.We study the firm's optimal contract menu with and without using the service-based model.We develop a game-theoretic model consisting of one manufacturing firm and farmers in the presence of the firm's asymmetric information on the farmers' knowledge level of operating drip systems. Analytical results show that the addition of the service-based option to the firm's contract menu (instead of the pure product-based model) promotes the adoption of drip irrigation systems. However, when the firm's operating cost is neither low nor high, such an addition can backfire by decreasing the profit of farmers with high skill levels. Moreover, when both the farmers' fertilizer efficiency and the profit-maximizing firm's water efficiency are low, compared with the pure product-based model, this firm's optimal contract can decrease the total agricultural product supply and total water usage, while increase the total fertilizer usage.
