Disagree. Research has consistently shown that American multinationals consistently apply better corporate management practices than their European counterparts.[1] This is especially true in IT-intensive industries.[2] This is true even when comparing American multinationals operating in Europe.
Any sufficiently large company in a globally integrated, competitive industry, is going to reap potentially large efficiency gains by replacing European management with American management.

Also, it's not like in economics/business science there's a European vs American distinction in publications. The European Economics Association is quite small and most European departments hire out of the American association's market, for instance
European companies grow to a certain size, and are then either sold to an established American company or relaunched from Silicon Valley with American investments.
I think most of this is tax driven. American tax rules allow venture funds and also private wealth to accumulate and grow easier than European counterparts. The American government simply allows its business and private individuals to accumulate money via off shore companies in the Caribbean. The US deliberately allows this.
