When the Bank of Northern Minnesota (BNM) Acquired a Major

When the Bank of Northern Minnesota (BNM) acquired a major investment firm,senior executives noticed hostilities forming between the financial analysts in the investment company and the bank's marketing people who provide marketing expertise for the investment firm's mutual funds and other investment vehicles.The marketing staff said that the finance staff did not care much for the needs of the customers.They partly attribute this to the poor marketing expertise in the investment firm before BNM bought it.The analysts,many of whom have graduate degrees from top universities,privately complained that the marketing types did not have enough brainpower to turn on a light switch.Use the social identity theory to explain why these hostilities might have existed.
