New research from the University of Bath shows that graduates of elite MBA programmes, particularly the so‑called M7 super‑elite US schools, are significantly more likely to become top management team members and CEOs than those with non‑elite MBAs or no MBA at all. However, the study of more than 106,000 executives in S&P 500 companies between 2000 and 2018 showed the benefits of holding an elite MBA were not evenly spread between men, women and minorities, and altered according to the prevailing economic winds.

A new study in the American Economic Journal: Applied Economics assessed life trajectories of children in Lesotho, Africa, across a wide range of educational and later-life outcomes. The study found that children who enrolled in primary school at an older age—despite an initial disadvantage in years of schooling—were more likely to remain in school through adolescence, obtained higher total years of schooling, and developed greater literacy than children who began primary school at younger ages. The older children were also more likely to delay marriage, have fewer children, hold higher-earning jobs, and accumulate greater wealth.

Warren Buffett advised that you should never invest in a business you can’t understand. But that hasn’t stopped many investors.

New research from the McCombs School of Business at The University of Texas at Austin might help them better understand the complications of companies they’re investing in. The study offers the most precise and comprehensive tool yet for measuring business complexity.

The tool, devised by Sara Toynbee, associate professor of accounting, simplifies the measurement by using artificial intelligence. It also finds that in areas such as structuring debt, complexity can sometimes be a good thing.
