First, on the systemic level, Pollins (2008) advances Modelski and Thompson's (1996) work on leadership cycle theory, finding that rhythms in
the global economy are associated with the rise and fall of a pre-eminent power and the often bloody transition from
one pre-eminent leader to the next. As such, exogenous shocks such as economic crises could usher in a redistribution
of relative power (see also Gilpin, 1981) that leads to uncertainty about power balances, increasing the risk of
miscalculation (Fearon, 1995). Alternatively, even a relatively certain redistribution of power could lead to a permissive
environment for conflict as a rising power may seek to challenge a declining power (Werner, 1999). Separately, Pollins
(1996) also shows that global economic cycles combined with parallel leadership cycles impact the likelihood of conflict among major, medium
and small powers, although he suggests that the causes and connections between global economic conditions and security conditions remain
unknown. Second, on a dyadic level, Copeland's (...
