Antitrust institutions and policies in the globalising economy Eleonora Poli provides a coherent and comprehensive explanation of the diffusion of liberal and neo liberal competition policies in the USA Europe Japan and the BRICS from an international political economy perspective. She investigates whether how and why these countries have progressively changed their respective interpretations of market competition in light of major economic crises or political and economic issues giving rise to the current neo liberal era. More specifically she analyses whether they responded to each downturn or pressure from the international arena through the enforcement of antitrust regimes and if so how and why specific institutional changes were implemented. In doing so she focuses on whether policy diffusion mechanisms favoured the adoption of similar antitrust policies.
