Interesting statistic in the article about a 25% reduction of Fortune 500 female CEOs in the last year. They have discussed female CEOs on Freakonomics podcast a fair bit including the theory that shareholders and employees prefer a CEO with more masculine traits when the economy is good (aggressive, risk-taking, outward-facing). And people prefer more feminine traits when the company is struggling (care-taking, risk-aversion). Interesting theory and the economy has been doing well in the last year.
