In the sports world, particularly in the NBA, it's taken for granted that some athletes will start mailing it in after they receive their big guaranteed contract. It turns out that CEOs do the same thing:
We study real estate purchases by major company CEOs, compiling a database of the principal residences of nearly every top executive in the Standard and Poor’s 500 index. When a CEO buys real estate, future company performance is inversely related to the CEO’s liquidation of company shares and options for financing the transaction. We also find that, regardless of the source of finance, future company performance deteriorates when CEOs acquire extremely large or costly mansions and estates.
BTW, if you haven't started reading Marc Andreessen's blog, you are missing out.
