The analysis indicates that billionaires in rent-thick sectors have higher wealth levels, on average. As well, the evidence also supports lower wealth for self-made and entrepreneurial billionaires. The findings also reveal that self-interested actions by billionaires tend to raise agency costs, which, in turn, dampens profitability and firm value. Finally, there is evidence which suggests a tendency on the part of billionaires to block innovative activity. JEL Classification: D31, N35, P52
