    It is fashionable today to criticize Big Business, and there is one issue on which the many critics agree: CEO pay. We hear that CEOs are paid too much (or too much relative to workers) , or that they control others’ pay, or that their pay is insufficiently related to positive outcomes. But the more likely truth is CEO pay is largely caused by intense competition.

It is true that CEO pay has gone up---top ones may make 300 times the pay of typical workers on average, and since the mid-1970s, CEO pay for large publicly traded American corporations has, by varying estimates, gone up by about 500%. The typical CEO of a top American corporation-from the 350 largest such companies-now makes about $18.9 million a year.

While individual cases of overpayment definitely exist, in general, the determinants of CEO pay are not so mysterious and not so trapped in corruption (腐败). In fact, overall CEO compensation for the top companies rises pretty much in line with the value of those companies on the stock market.

The best model for understanding the growth of CEO pay, though, is that of limited CEO talent in a world where business opportunities for the top firms are growing rapidly. The efforts of Americans highest-earning 1 % have been one of the more dynamic elements of the global economy.

It’s not popular to say, but one reason their pay has gone up so much is that CEOs really have upped their game relative to many other workers in the U. S. economy.

Today’s CEO, at least for major American firms, must have many more skills than simply being able to “run the company.” CEOs must have a good sense of financial markets and maybe even how the company should trade in them. They also need better public relations skills than their predecessors, as the costs of even a minor slipup can cause a bad consequence. Then there’s the fact that large American companies are much more globalized than ever before, with supply chains spread across a larger number of countries. To lead in that system requires knowledge that is fairly incredible.

There is yet another trend: virtually all major American companies are becoming tech companies, one way or another. An agribusiness company, for instance, may focus on R&D in highly IT- intensive areas such as genome sequencing (基因组序列). Similarly, it is hard to do a good job running the Walt Disney Company just by picking good movie scripts and courting stars ； you also need to build a firm capable of creating significant CGI (计算机生成图像) products for cartoon movies at the highest levels of technical sophistication and with many frontier innovations along the way.

On top of all of this, major CEOs still have to do the job they have always done- which includes motivating employees, serving as an internal role model, helping to define and extend a corporate culture, understanding the internal accounting, and presenting budgets and business plans to the board. Good CEOs are some of the world’s most powerful creators and have some of the very deepest skills of understanding.
