He has also produced a number of mathematical models describing specifically long-term political-demographic dynamics of Egypt and used them for a demographic structural analysis of the 2011 Egyptian Revolution. Korotayev was one of the first to predict and assess the June 2013 Egyptian protests. Note also his study of 20132014 revolutionary wave and his interpretation of the Arab Spring events as a trigger of a global "phase transition". Of special importance is his study of the hypothesis that population pressure causes increased warfare. This hypothesis has been recently criticised on the empirical grounds. Both studies focusing on specific historical societies and analyses of cross-cultural data have failed to find positive correlation between population density and incidence of warfare. Korotayev, in collaboration with Peter Turchin, has shown that such negative results do not falsify the population-warfare hypothesis. Population and warfare are dynamical variables, and if their interaction causes sustained oscillations, then we do not in general expect to find strong correlation between the two variables measured at the same time (that is, unlagged). Korotayev and Turchin have explored mathematically what the dynamical patterns of interaction between population and warfare (focusing on internal warfare) might be in both stateless and state societies. Next, they have tested the model predictions in several empirical case studies: early modern England, Han and Tang China, and the Roman Empire. Their empirical results have supported the population-warfare theory: Korotayev and Turchin have found that there is a tendency for population numbers and internal warfare intensity to oscillate with the same period but shifted in phase (with warfare peaks following population peaks). Furthermore, they have demonstrated that in the agrarian societies the rates of change of the two variables behave precisely as predicted by the theory: population rate of change is negatively affected by warfare intensity, while warfare rate of change is positively affected by population density. As Kohler and Reed put it, Korotayev and Turchin have demonstrated that "human population movements and sociopolitical strife play the roles of sometimes endogenous, sometimes exogenous, factors that on small spatial scales may seem inexplicable but which on longer temporal and wider spatial scales may have understandable rhythms". Thus, Korotayev has demonstrated that the Malthusian trap tends to generate sociopolitical upheavals. On the other hand, he has shown that the escape from the Malthusian trap is accompanied by another "trap" generating new sociopolitical upheavals (what he calls "a trap at the escape from the trap").

==== Russian demographic crisis ====

In collaboration with Daria Khaltourina he has made a significant contribution to the study of the factors of the Russian demographic crisis of the 1990s/early 2000s. They have demonstrated that post-Soviet Russia experiences one of the world's highest prevalence of alcohol-related problems, which contributes to high mortality rates in this region. Reduction in alcohol-related problems in Russia can have strong effects on mortality decline. They have analysed the plausibility of application of general principles of alcohol policy translated in the Russian Federation. Korotayev and Khaltourina have shown that alcohol policy approaches could be implemented in the same ways as they have been in other countries, and contributed to the development of alcohol control measures in this country. In addition, according to Korotayev, there should be special attention to decreasing distilled spirits consumption, illegal alcohol production, nonbeverage alcohol consumption, and enforcement of current governmental regulations. In late 2014 they correctly predicted the forthcoming return of Russia to negative natural population growth.

==== "Literacy and the Spirit of Capitalism" ==== Korotayev and his colleagues have demonstrated that Protestantism has indeed influenced positively the capitalist development of respective social systems not so much through the "Protestant ethics" (as was suggested by Max Weber) but rather through the promotion of literacy.

They draw attention to the fact that the ability to read was essential for Protestants (unlike Catholics) to perform their religious duty to read the Bible. The reading of Holy Scripture was not necessary for Catholic laymen. The edict of the Council of Toulouse (1229) prohibited Catholic laity from possessing copies of the Bible. Soon after that, a decision by the Council of Tarragona spread this prohibition to ecclesiastic people as well. In 1408, the Oxford Synod absolutely prohibited translations of the Holy Scripture. From the very beginning, Protestant groups did not accept this prohibition. Thus, Luther translated in 15221534 first the New Testament, and then the Old Testament, into German, so that any German-speaking person could read the Holy Scripture in his or her native language. Moreover, the Protestants viewed reading the Holy Scripture as a religious duty of any Christian. As a result, the level of literacy and education was, in general, higher for Protestants than it was for Catholics and for followers of other confessions that did not provide religious stimuli for learning literacy. Literate populations have many more opportunities to obtain and use the achievements of modernisation than illiterate ones and display greater innovative-activity levels, which correspond with opportunities for modernisation, development, and economic growth. Empirical tests performed by Korotayev and his colleagues have confirmed the presence of a rather strong and highly significant correlation between the early introduction of mass literacy and subsequent high rates of capitalist economic development.
