Why is it rational to pay out a dividend?
The real value of a share of stock is the current cash value of all dividends the owner will receive, plus the current cash value of the final liquidation if any.  Since people with different needs may judge the current cash value of an income stream differently, there would be a market basis for people to buy and sell stocks even if everyone could predict all future payouts perfectly. If shareholders knew that a company wouldn't pay any dividends until it was liquidated in the year 2066, whereupon it would pay $2000/share, then each share would in 2016 effectively be a fifty-year zero-coupon bond with a $2000 maturity value.  While some investors would be willing to trade in such an instrument, the amount of money a company could charge for such an instrument would be far lower than the money it could charge for one with payouts that were more evenly distributed through time. Since the founders of most companies want their companies to be around for a long time, that would mean that shareholders would have no expectation of their shares ever yielding anything of value within any foreseeable timeframe.  Even those who would be more interested in share-price appreciation than dividends wouldn't be able to see share prices rise if there wasn't any likelihood of the stock being bought by someone who wanted the dividends.
