Previous studies report that semi‐democratic regimes are less durable than both democracies and autocracies. Still, mixing democratic and autocratic characteristics need not destabilize regimes, as three highly plausible alternative explanations of this correlation remain unaccounted for: (a) semi‐democracies emerge under conditions of political instability and social turmoil; (b) other regime characteristics explain duration; and (c) extant democracy measures do not register all regime changes. We elaborate on and test for these explanations, but find strikingly robust evidence that semi‐democracies are inherently less durable than both democracies and autocracies. "Semi‐democracies are particularly unstable political regimes" should thus be considered a rare stylized fact of comparative politics. The analysis yields several other interesting results. For instance, autocracies and semi‐democracies are equally likely to experience "liberalizing" regime changes more specifically, and once accounting for differences in degree of democracy, there is no robust evidence of differences in duration between military and single‐party regimes.

The article predicts changes in global and regional incidences of armed conflict for the 2010-2050 period. The predictions are based on a dynamic multinomial logit model estimation on a 1970-2009 cross-sectional data set of changes between no armed conflict, minor conflict, and major conflict. Core exogenous predictors are population size, infant mortality rates, demographic composition, education levels, oil dependence, ethnic cleavages, and neighborhood characteristics. Predictions are obtained through simulating the behavior of the conflict variable implied by the estimates from this model. We use projections for the 2011-2050 period for the predictors from the UN World Population Prospects and the International Institute for Applied Systems Analysis. We treat conflicts, recent conflict history, and neighboring conflicts as endogenous variables. Out-of-sample validation of predictions for 2007-2009 (based on estimates for the 1970-2000 period) indicates that the model predicts well, with an area under the receiver operator curve of 0.937. Using a p>.30 threshold for positive prediction, the true positive rate 7-9 years into the future is 0.79 and the False Positive Rate 0.085. We predict a continued decline in the proportion of the world's countries that have internal armed conflict, from about 15% in 2009 to 7% in 2050. The decline is particularly strong in the Western Asia and North Africa region and less clear in Africa south of Sahara. The remaining conflict countries will increasingly be concentrated in East, Central, and Southern Africa and in East and South Asia. Adapted from the source document.
