In recent years, there has been growing concern that a trend has emerged in which markets around the world are becoming more concentrated and less competitive. This is sometimes attributed to the increasingly digital and globalized nature of many markets and the firms that operate within them. In other cases, lax antitrust enforcement or excessive regulation have been blamed for the increase of concentration.
