Tax Policy and the Dividend Puzzle
This paper offers a new explanation of the dividend puzzle, based upon a model in which firms attempt to signal profitability by distrubuting cash to shareholders. I assume that dividends and repurchases are identical, except that dividends are taxed more heavily. Nevertheless, I demonstrate that, under certain plausible conditions, corporations will pay dividends. Indeed, some firms will actually pay dividends, and then retrieve a portion of these payments by issuing new equity (perhaps through a dividend reinvestment plan), despite the fact that this appears to create gratuitous tax liabilities. In addition to providing an explanation for the dividend puzzle, I also derive a number of strong results concerning corporate payout decisions and government tax policy. Some of these results are surprising. For example, the relationship between repurchases and firm quality is hump-shaped. Moreover, despite the fact that a higher dividend tax rate depresses dividend payments, it does not affect either government revenue or welfare.
