Guided "Free" Fall

Have you ever wondered why do analysts working for banks and brokerage firms provide stock recommendations and advise in newspapers? I mean they don't get paid for it and why pass such information on if it can make money?

A research paper on Reasons for Channeling Information listed the following 5 reasons for this:

First, the analyst employer have incomes based on transaction fees; an increased trading volume consequently leads to an increased income. Recommendations in the printed media will presumably lead to an increase in trading volume and thereby an increase in analysts' income.
Second, they may also have private clients who have recently taken, or are about to take, positions in certain securities; hence a 'helping-hand' phenomenon
may be a reason for analyst recommendations.
Third, they may also have, or be willing to get, the firm whose stock they recommend as a future client.
Fourth, it is an opinion driven factor wherein their beliefs on a particular stock are re enforced by them recommending the same stock.
Fifth, there may be a reputational aspect involved as well; analysts would
want to have a reputation as giving valuable and accurate recommendations
rather than the opposite.
