Idea merchants and paradigm peddlers in global antitrust

In global antitrust, policy paradigms circulate according to forces analogous to those of the market. Policy entrepreneurs operate in a setting where, notwithstanding various cooperative platforms, competition and rivalry occur and are manifest across a number of dimensions. This chapter thus begins from the premise that competition enforcers in jurisdictions around the world compete among themselves in a global 'market'. The primary competitive relationship explored in this chapter is that between enforcers in the United States and enforcers in the European Union, but the discussion also accounts for antitrust's global expansion, with the multiplication of antitrust jurisdictions ('new entrants') around the world.
