Power of Corporations
Recent study suggests that a few key corporations influence or control most equity holdings in most countries:
Based on their analysis, Glattfelder and Battiston identified the ten investment entities who are “big fish” in the most countries. The biggest fish was the Capital Group Companies, with major stakes in 36 of the 48 countries studied. In identifying these major players, the physicists accounted for secondary ownership — owning stock in companies who then owned stock in another company — in an attempt to quantify the potential control a given agent might have in a market.
The results raise questions of where and when a company could choose to exert this influence, but Glattfelder and Battiston are reluctant to speculate.
“In this kind of science, complex systems, you’re not aiming at making predictions [like] … where the tennis ball will be at given place in given time,” Battiston said. “What you’re trying to estimate is … the potential influence that [an investor] has.”
Glattfelder added that the internationalism of these powerful companies makes it difficult to gauge their economic influence. “[With] new company structures which are so big and spanning the globe, it’s hard to see what they’re up to and what they’re doing,” he said. Large, sparse networks dominated by a few major companies could also be more vulnerable, he said. “In network speak, if those nodes fail, that has a big effect on the network.”
Sobering.
