Unlike recent tendencies to specify the variety of postsocialist trajectories, this article attempts to characterize the common features of postsocialist capitalism, as it has developed since the 1990s in Eastern Europe. Using conceptual tools of economic sociology, the postsocialist socio-economic organization is analyzed as embedded economy, the institutionalization of capitalism as a moral project, and the pervasiveness of informality from the networks and culture perspectives. Economic development is viewed as dependent, simultaneously, on the system's structural, political and cultural features. For postsocialist capitalism, these features include lack of state autonomy due to close coupling of political and economic roles; the embrace of greed and self-interest as legitimate motives for action; and persistence and bolstering of informality as modus operandi. Stipulations about developmental consequences are provided in the conclusion.Keywords Political and economic transformation . Eastern Europe . Embedded economy . Moralized markets .

Development Scholarship on the socio-economic changes after the communist transitions in Eastern Europe has focused on the intra-regional differences in development, inspired by the literature on the varieties of capitalism (Hall and Soskice 2001) to specify varieties of postsocialist capitalism (King and Szelenyi 2005;Feldmann 2007;Noelke and Vliegenthart 2009;Bohle and Greskovits 2012;Bruszt 2012). In contrast, the present article proposes to bracket the obvious cross-country differences and to challenge the received wisdom, asking if, possibly, we can identify some common institutional features for countries, which underwent relatively rapid simultaneous political and economic transformations from socialism to capitalism. 1 The article does so by applying conceptual Theor Soc DOI 10.1007/s11186-016-9265-z 1 The emphasis is on rapid simultaneous political and economic transformations toward a capitalist democracy, which means that the scope of countries discussed here does not include countries of Central Asia and South Caucasus, nor China, Vietnam, and Laos.
