This is a study of the nature of internal diversity within liberal and collaborative market economies. Based on large scale comparative survey data, we assess the extent to which specific clusters of practices are associated with specific varieties of capitalism. Given that recent literature has pointed to internal diversity within specific national contexts, we explore the nature of internal diversity within both liberal and collaborative market economies, and what makes each variety of capitalism distinct. We find that more than one cluster of practices is indeed likely to be encountered in a particular national context, but that this diversity was bounded: only a limited number of alternative paradigms are likely to emerge and persist. The survey findings not only shed light on the nature of this internal diversity, but also reveal the fact that liberal and collaborative markets remain distinct, with the rights accruing to employees being more deeply embedded in a wide cross section of firms within the latter. This is a study of the nature of internal diversity with liberal and collaborative market economies. Based on large scale comparative survey data, we assess the extent to which specific clusters of practices are associated with specific varieties of capitalism. Given that recent literature (Brewster, Wood and Brookes 2006;Crouch 2005; Crouch and Voelkzow 2004) has pointed to internal diversity within specific national contexts, we aim to explore the nature of internal diversity within both liberal and
