We examine how selection bias in the promotion of CEO amplifies risk taking, using prenatal exposure to pollution such as exogenous shock for individual risk preferences.
The idea is that reckless CEOs are born in that way. The question that seeks to answer is related to whether companies with a culture of high risk tolerance tend to choose a CEO with a similar character, or if companies involuntarily promote risk makers based on their fate:
If promotion systems reward executives whose risky decisions succeeded in low -risk environments, companies can raise it without knowing people whose leadership style reflects survival bias instead of skill. This concern is especially relevant to internal candidates, which represent more than 70 percent of CEO’s appointments.
The authors of the study, P. Raghavendra Rau, Yilin Wu and Richard Lok-Si Ieong, choose as measure the “biological shock” of the prenatal exposure to pollution. It is a different approach for previous research on risk tolerance and early life, which has concentrated after the CEO is born.
Children of the Great Depression, for example, show High financial risk aversion By becoming CEO, except when their families were rich enough to protect them from difficulties. Children exposed to fatal natural disasters in childhood become Risk handle ceosBut that could be due to the fact that they were raised by a family that chose to live in a disasters -prone region. Having rich or reckless parents will affect the career of a person in innumerable difficult ways to measure, so it is difficult to discharge the effects of the effects of corporate selection. Taking all the way back to conception eliminates these complicated factors, argue the authors.
There is a good amount of evidence that if a baby is exposed to toxic chemicals in the uterus, it will be more impulsive and aggressive, more ADHD prone and with a greater risk of adult crime.
The document method is to estimate the probability of a CEO to develop these features based on whether they were born near the black points of US industrial pollution. UU. Known as Superfund sitesthat qualify for toxicity on the date of birth. There were more than 1800 sites of this type in the United States as of December 2018.
To be born near a hazardous waste site makes a person less likely to become CEO, the study discovers, what could be for biological or economic reasons. However, being exposed to pollution makes a person more likely promoted to the CEO.
Almost all CEO included in the data set were born before such environmental hazards were widely recognized, so the data offers a clean measure of innate risk appetite, the authors argue. The lines in the table below mark the publication of the influential exposure of Rachel Carson of the chemical industry, Silent Spring; the formation of the United States Environmental Protection Agency; and the proposal of the Superfund Law that was approved in 1980:
The study also finds that the so -called superfund CEO are not disproportionately in high -risk sectors. Employees who rise to superior work in Superfund
From this, the authors make some inferences on how the prenatal toxic load affects the management style:
The CEOs that are not superfund can advance through consistent consistent performance. The CEOs of Superfund, on the contrary, are more likely to take internal risks of high variance, such as aggressive restructuring, which sometimes generate outstanding results. When these bets are worth it, they are difficult to distinguish from skill. Companies, observing only the results, can systematically promote risk takers whose behavior is only revealed under the high risk pressure of exposed decision making. This selection bias driven by survival offers a novel explanation of why some CEO perform well in the internal roles, but hesitated once.
Empirically, we find that superfund CEOs are significantly more likely to be promoted internally instead of hiring externally, suggesting that companies have considerable weight on previous internal success. Once in office, these CEO pursue external financial policies significantly more risky: higher leverage, lower cash possession and unrelated acquisitions. Their companies exhibit a greater volatility of actions, lower credit grades and higher indebted costs.
There are enough conjectures underlying this statement. The study does not directly observe the decision making of an executive before becoming a boss. He Peter principle It is a convincing explanation, not a demonstrable trend.
Instead, the study measures the consequences. A company whose CEO was born in a county with a Superfund site will add almost 19 percent to its bankruptcy risk score and will make the breach more than 7 percent more likely, discover. The yields of purchase and retention actions are a bit worse, but probably not enough to become a factor.
However, there is also an unusually high number of CEO of superfund leaders in Fortune’s The most admired companies in the United States Top 50. It would make sense that a cohort with a greater propensity to the bet will result in some winners and many losers.
The document concludes:
Our findings help explain why companies can systematically overturn to risk engines whose internal success reflects luck, not the ability. In doing so, we show how performance -based promotion systems can inadvertently channel high -risk people to positions where their features are misaligned with paper demands, creating a structural risk source at the company level that is hidden and difficult to correct.
Regardless of what you do with the argument, the data set yields a strange peculiarity. The most toxic county in the United States, with 23 active superfund sites, is Santa Clara County in California. Santa Clara is also where almost all American technological companies are headquarters.
Silicon Valley, the spiritual home of risk taking and creative destruction, was built around the toxic legacies of local operators, including Intel, HP, Applied materials and National semiconductor. We are not saying that there is any connection. It would be very incorrect to suggest that the culture of American technological management is a poisoning by -product to babies not born soft enough to become CEO and administer to companies in bankruptcy. That would be ridiculous, reductive and limit offensive. All we are doing is observing the correlation.
