Uneven and combined development: convergence realism in communist regalia?

Leon Trotsky's notion of 'uneven and combined development' (UCD) has been gaining traction as an explanatory theory of international relations over the past decade, notably in work by Justin Rosenberg and Alexander Anievas. The idea that the uneven sequencing of economic development between countries affects both their relative power relationships and domestic political stability, in particular, carries prima-facie intuitive plausibility. The potential consequences for international stability of such relative power shifts and domestic upheavals suggest, furthermore, that there may be significant explanatory payoffs from this line of investigation. At the same time, however, the UCD intuition raises other questions about causal foundations and theoretical affiliations. What accounts for the sequencing of uneven development, for example? And how exactly do both relative power shifts and domestic political instability elevate war risks? This paper will address these lacunae, by demonstrating that – at the level of its underlying micro-foundations – UCD can be understood as a compound of catch-up convergence growth theory and security-dilemma realism. Such a recognition paves the way, in turn, for a fruitful application of UCD to contemporary questions in international politics. [ABSTRACT FROM AUTHOR]
