Mechanism
Synthesis from 1 study
When one oil company has a major accident, investors blame only that company and don’t think the whole industry is risky. That’s why other oil companies’ stock prices don’t drop — people see it as one company’s problem, not everyone’s.
Most probable mechanism
Investors evaluate each company’s actions and history separately, so when one company has a major accident, they do not assume all companies in the same industry are equally at fault or at risk. This keeps the stock prices of other companies stable even when one company suffers a major loss.
Investors process information about corporate misconduct as isolated events tied to specific management decisions, operational practices, or geographic exposures rather than as indicators of systemic industry failure.
