If price is belоw equilibrium:
Pаt purchаsed а shelving unit frоm R-Cо fоr use in his garage. The shelving unit had wooden shelves which were mounted into metal railings using metal pins. The shelving unit had been manufactured by M-Co who sold it to a distributor, D-Co, who sold it a wholesaler, W-Co, who sold it to R-Co. Pat took the shelving unit home and assembled it using instructions provided to Pat with the shelving unit. The instructions indicated that the shelving unit would safely store up to 300 pounds. Pat placed boxes on the shelves. Together, the boxes weighed 250 pounds. One day as Pat was walking by the shelving unit in his garage, it suddenly twisted and fell over. Pat was struck by the shelving unit and boxes it had been holding and was injured. The shelving unit also struck Pat’s car causing the car to sustain damage. Later investigation revealed that the plans and specifications used to manufacture the shelving unit developed by M-Co called for “Type-1” metal pins. In fact, Type-1 pins were used in the shelving unit but were not suitable as they would snap off eventually after being put under the stress of weight. Type-2 pins should have been called for in the plans and specifications. When the Type-1 pins had snapped, this caused the shelving unit to twist and fall over. Discuss.
