C&S Authors Article for Finnish Competition Law Association Yearbook 2020

Common ownership refers to a situation where stock investors—usually institutional investors such as pension funds, insurance companies, or mutual investment funds—have minority holdings in companies that compete in the same relevant market. The purpose of the article is to contextualise some of the current legal and economic understanding of the anti-competitive effects potentially stemming from common ownership in addition to providing a framework for identifying and assessing the circumstances under which common ownership may lead to anti-competitive outcomes.
