Building from the theoretical literature I posit here that repressors' reac
tions to perceived domestic threats in Argentina and Chile from the 1940s t
hrough the 1980s are determined in large part by four independent factors:
incidence of collective political opposition, policy inertia, policy memory
, and pervasive military control The model works reasonably well in both co
untries Findings for the two latter, interactive factors in particular sugg
est a way that analysts can go beyond the typical additive approach to mode
ling state repression (repression as a function of factor X-1 + factor X-2
+ factor X-i) to include temporal interactive affects into their analyses.
I argue that this approach presents a new and promising direction in our qu
est to understand the dynamic nexus between repressors and their opponents.
