Furthermore, supposing there were some sort of absentee owner effect (boards of directors are comprised of other CEOs, and they conspire to raise each other's pay), you'd expect to see a different market value in closely held corporations. Strangely, the price of a CEO for a closely held corporation closely tracks the price of a CEO for absentee shareholders.

The obvious way to fix this is with increased shareholder activism (ala Gordon Gekko), and reducing regulations on hostile takeovers. Possibly also regulating things like poison pills, staggered board elections, etc. Do you favor such rule changes? If not, why not?
This will be unpopular but I think all salaries should be made public. This would allow a lot of people to negotiate better salaries.
I don't know, is what I think I'm trying to say. There hasn't been a lot of data...very few companies are open about the salaries they pay, and there is a definitely hesitation among employees about discussing their salary (and it is often discouraged by the company, to boot).
We have developed a tolerance for executives being paid extravagantly just in the past generation, or so. It wasn't always the case, and it is at least as much a function of what people are willing to accept as what the market necessitates.
When market value is set by the CEOs themselves, the trend in market value is ever upward, as long as there is no pressure in the opposite direction. The highest paid executives have seen their share of the pie grow drastically over the past couple of decades, while fantasy stories of their importance and value get passed around to convince everyone that a CEO making 250 times the average worker salary is perfectly reasonable.
Competence has value, but the royal treatment of C-levels is absurd.
