There is a theory that money is power and people or corporations that control large amounts of wealth yield more influence. However, how do we measure this power. When companies are ranked based on such things as market capitalization, revenue, assets, the rankings very greatly depending on the criteria used. For instances banks tend to have large amounts of assets but because they are highly leveraged they may not be valued the great as some non finical institutions by the market. Still the fact that they own a lot could mean that they wield significant power even if they aren't the most profitable companies. Based on the above ways we can rank a company what metric would best determine market power?
