The term ‘asset cluster’ refers to an ownership pattern in which one agent owns a large number of assets while the other owns none. Arguably, asset clusters are one of the most evident ownership patterns that we observe since most firms own large numbers of assets while their workers typically have no ownership rights over the assets they use in the production process.
