Firms that have market power can apply the mixed bundling strategy to increase their profits. Some researchers claim that even if a firm does not have any market power, i.e., even in a competitive market, firms can use mixed bundling (for example, those small restaurants/fast food restaurants located in the shopping malls). Explain why and how firms in competitive markets may apply mixed bundling. Provide a numerical example to prove your case. Please give a numerical example. I need a help particularly this part of question.
