Caught in a low-level equilibrium, trapped states appear to be in a perpetual political and economic limbo that can last for years and in several cases, decades. Our goal is to determine those features that trapped states have in common, and compare changes in those features over time with states that have successfully exited. The paper unfolds in four parts. In the first part we examine key concepts underpinning fragility traps in addition to conducting a review of current theorizing. In the second part we present the results of our large sample analysis. In the third part we compare the results of our comparative case studies with findings from the large sample analysis. In the fourth and final section we conclude with a discussion on how our findings inform policy. 1 Our prior research on traps focused on examples of specific state transitions but did not explore the question of causes (Carment et al 2015).2 With a focus on Africa, Andrimihaja et al. (2011) found that not only do the continent's fragile states grow more slowly than non-fragile states, the probability that a fragile state in 2001 was still fragile in 2009 was 0.95. According to the authors, corruption, political instability and violence, insecure property rights, and unenforceable contracts conspire to create a 'slow-growth-poor-governance equilibrium trap' into which these most fragile states fall and which they denote as a fragility trap. They suggest growth focused aid will not work in such cases. 3 In our previous research we found that fragility correlated strongly with economic growth, aid to fragile states tended to be more volatile and many states tended to be over aided beyond their absorptive capacity (Carment, Samy and Prest 2008). We also found that aid focusing on state society relations tends to be neglected relative to building strong state capacity and authority. A key factor in determining long-term stability, namely legitimacy, is generally ignored in the policy process (Carment, Prest and Samy 2008).
