ABSTRACT This article has two main aims. The first is to problematize the dominant view of the informal economy as a sort of separate economy, related primarily to (immigrant) small business and distinct from the so-called formal economy, which for the most part encompasses big companies as well as state economic activities. In contrast, the present article assumes that all economic actors are increasingly ready to adopt informal economic strategies to secure their economical survival. In line with this assumption, the second aim of the article is to contribute to our knowledge of the causes of, as well as the actors within, the current informalization trends that characterize Western economies. The article concludes that the informalization of contemporary advanced economies in general terms is a result of a structural conflict between new economic trends and old regulatory frameworks. These frameworks, with their focus on decommodification, have become too restrictive for new forms of capital accumulation, with their focus on flexible adaptation, which include an increasing demand for the re-commodification of labour. The conflict emerges and intensifies, among other reasons, because of the radically different internal operational logics, agendas and priorities that characterize these two social processes.
