> via their own shares increasing This isn't any more true for the executives than any other shareholder, and doesn't really work that way anyway.

The buybacks may be a bad idea and lower the demand from the marketplace but that information takes more time to disseminate and is harder to actually determine where as someone buying up millions of shares is a piece of information that is immediatley known. >You ob…
The company has a value. If the P/E ratio gets worse because the share price went up with the same earnings, more investors will find it profitable to cash out and invest in something with a better ROI.

Except that then the perverse incentive for managers becomes to boost the stock price by not issuing dividends, since dividends reduce the stock price. The only real way to fix it is to fix their incentives, and once you do that you're back to preferring buybacks due to the tax treatment.
