Examples (and Non-Examples) of Social Cycle Theories

Let us try to distinguish true social cycle theories from cycle theories involving humans but not representing true social cycles. Let us define a true social cycle as one in which both the initial disruption, the subsequent adjustments, the disruptions that follow them, the adjustments that follow on, and so on, are all primarily social in nature, i.e., they are driven by human action and the social environment that gives human action its setting. Let us offer a paradigmatic case of a true cycle that is not a social cycle: the spike in the sale of sunscreen in the summer, and its trough in the winter. This cycle clearly includes human action and social factors, but the primary driver of the cycle is the earth's rotation around the sun, a distinctly non-human, non-social phenomenon. That, we will say, is a genuine cycle, but not a social cycle. The fact that farmers en masse plant corn in the spring and harvest it in late summer is another such cycle: it is obviously true that they do so, so in saying that is not a true social cycle I am not disputing the facts on the ground, I am just saying that a major factor driving this cycle is not social in nature.

In the following list, we are not concerned with whether a cycle theory is true, but merely whether it is a genuinely social cycle theory.

Some social cycle theories:

1) The Aristotelean-Polybian theory of anacyclosis: Here, it is the weakness inherent in each form of good rule (monarchy, aristocracy, democracy) that drive the system into the next form in the cycle. These are all social factors.
2) The Malthusian theory of the population cycle: Abundance drives population increase, which creates scarcity, which drives population reduction. Query: Is this really a social cycle, or is it more of a biological cycle?
3) Marx's theory of the business cycle: The "anarchy of capitalist production" drives waves of high investment, which prove over-optimistic, and are followed by a wave of low investment, producing the slump.
4) Pareto's theory of alternation of the elites: Any elite class rules either mostly by guile or mostly by force. Whichever is the case, a group within the non-elite class gradually comes to have a decisive advantage in the other means, and then, by force or guile, it displaces the current elite.
5) The Mises-Hayek theory of the business cycle: Too-low interest rates prompt the boom, which threatens to turn into the "crack-up boom," and that threat prompts higher rates. Those higher rates expose malinvestments, producing the slump. The response to the slump by the central bank is a renewal of too-low interest rates.
6) The Keynesian theory of the business cycle: The animal spirits of investors are riding high, but get spooked, by the threat of war, by a supply-side shock, by a threat of high tariffs, and so on. As a result, they reduce investment spending. That causes cut-backs in consumption spending which further spook investors, causing further reductions in investment spending, and so on. This continues (absent government intervention) until the price of capital goods sinks low enough that profit opportunities again become obvious: mathematically, we can use IS/LM model and the multiplier (in its negative manifestation) to see where this might occur, but the problems in that approach were pointed out early on by Hicks.
7) Callahan's theory of fads as social cycles. (Yes, this is a rather trivial example, but I think it is a real one, and highlights the phenomenon in a situation relatively free of ideological conflict. By doing so, I hope to penetrate past the ideological disputes towards the real essence of social cycles.)

Questions: 

What about Kondratiev? Schumpeter? Lucas? Do they have genuine social cycle theories?

What/who should we be looking at that we are not? Are the social cycle theories in anthropology? Linguistics? In sociology, besides Pareto?
