When the demand curve for a firm’s product is negatively sloped into the short run, in that case the firm: (i) operates in a purely or perfectly competitive market. (ii) experiences economies of scale in its production function. (iii) will face a horizontal demand curve in the long run. (iv) is in a decreasing cost industry. (v) has some control over pricing and is not a pure quantity adjuster.
