Why is it rational to pay out a dividend?
It comes down to the practical value of paying dividends. The investor can continually receive a stream of income without selling shares of the stock. If the stock did not pay a dividend and wanted continual income, the investor would have to continually sell shares to gain this stream of income, incurring transaction costs and increased time and effort involved with making these transactions.
