The image describes the positive impact of CEOs on businesses for twenty year rolling periods. The time period used is 1950 to 2009 — a period of fifty nine years. The scale used indicates year and impact in percentage.
At first glance, it appears that CEOs have had a huge impact on the business market, with their contributions seemingly taking up more than half of the graph, but closer inspection proves differently.
Actually, the CEO contribution to business improvement has been at an unsteady rate of ten percent for the six decade time period.
For the first thirty years, CEOs have contributed about ten to fifteen percent impact, starting from 1950 to 1980. For the most part, the CEOs have contributed to the lower range of the ten to fifteen percent frame, with an interesting surge for the last four years of the first half of this For the last four years of this period, CEOs made impact of fifteen percent or higher. A significant increase from the last twenty-six years.
From 1980 to the end, however, CEO impact was significantly raised when compared to the first half. Whereas they had previously made almost minimal impact — less than five percent impact for thirty years, CEOs initially began making about fifteen percent impact or slightly more for the first fifteen years and then twenty percent or near to twenty percent more impact after that.
