A tool to evaluate state capacity in post‐communist countries, 1989–2006

In an attempt to bring together the research on state capacity, this article proposes a five‐item index to operationalise and measure the concept of state capacity. The index was constructed for 26 post‐communist countries on a yearly basis from their first year of independence from communist rule to 2006. Different states unavoidably display dissimilar levels of aptitude in the different domains of state capacity, but the aggregated index of state capacity presented is high in both validity and reliability. With the help of this index, the starting conditions as well as the evolution of state capacity within the countries included in this study are explored, with three conclusions. First, post‐communist countries emerged displaying very contrasting levels of state capacity. Second, the level of state capacity has remained relatively stable within most countries between 1989–1991 and 2006, which ties in the last conclusion that the initial level of state capacity is the strongest determinant of subsequent levels of state capacity. All three conclusions carry important implications for research using state capacity either as an independent or as a dependent variable.
