This study constructs an equilibrium displace model that provides the framework to assess the effects of shifts in supply and demand curves and the changes in marketing costs on price and quantity under imperfect competition. The solutions of the model show that if middle men or food processors exercise market power when the procure raw agricultural products as well as when sell the products (or processed food), the changes in price and quantity that are incurred from exogenous shocks are smaller compared to the case that nobody exercise market power.
