In strategic-form games Selten's (1975) perfect equilibria are admissible. This is not true for extensive-form perfection. Quasi-perfect equilibria solves this problem using Selten's (1975) trembles to introduce a refinement of Nash equilibrium wherein each player puts infinitesimal weight on other players's strategies, but not her own. One might be sure of oneself, while (infinitesimally) unsure of others. However, also quasi-perfection itself is not without problems, precisely because it ignores future infinitesimal uncertainties in one's own play. We introduce a refinement; perfect quasi-perfect equilibrium, to capture the best of both concepts. Our idea is to force each player to consider infinitesimal deviations in her own future play, but to make them so unlikely that they are infinitely less likely than the combined likelihood of deviations by all other players. Our refinement uses only strategies that are neither weakly dominated in the strategic form nor in the agent normal form.

By isolating key variables and limiting their value, limiting case models portray processes that are empirically rare or nonexistent. Such models, however, have often been extremely useful in the analysis of events in the real world. The perfect competition model, borrowed from economics, has been useful in analysis of social behavior, but many social phenomena appear rather far removedfrom the limited assumptions of this model. This paper proposes two additional limiting case models-perfect benevolence and perfect malevolence-as alternative ideal descriptions. Insights from the three ideal models are then used to develop a more general model with less restrictive assumptions based on four variables: degree of monopoly, degree of explicitness, identification, and terms of exchange. Several empirical applications are discussed.

Citation: Castle, Clara Francelia. Perfect liberty. Senior thesis, Kansas State Agricultural College, 1894. ; Morse Department of Special Collections ; Introduction: Man early shared the love of greater gain, which generated oppression and bondage. The question of liberty has been the thought and highest interest of the nations. Much study has been put upon the beginnings and growth of liberty; and to understand its nature, has been the desire of man. Often, for the best growth of liberty, there must be revolution and bloodshed, before it can be fully established. The settlement of the colonies, the separation from England, and the civil war, examples of revolution that were necessary, for the higher advancement of liberty. Individual and civil liberty are closely connected. Religion, society, and custom, may be transformed into a yoke that binds. The final triumph, when perfect liberty will exist.

In this paper, I will develop a new theory of the nature of happiness, or "perfect happiness." I will examine what perfect happiness is and what it is not and I will try to answer some fundamental questions about this property. According to the theory, which I shall call "the fulfillment theory," perfect happiness is perfect fulfillment. The analysis of happiness in this paper is a development of the old idea that happiness is getting what you want and can be classified as a kind of desire-satisfaction theory. According to the fulfillment theory of happiness, it is necessarily the case that an individual x is perfectly happy if and only if all x's wants are fulfilled. The interpretation of this basic definition is important, since the consequences of the particular version defended in this essay are radically different from the consequences of many other popular theories of happiness. The fulfillment theory is also quite different from most other desire-satisfaction theories of happiness. We will see that it has many interesting consequences and that it can be defended against some potentially serious counterarguments. The upshot is that the analysis of (perfect) happiness developed in the present paper is quite attractive.

Along rivers in Bali, small groups of farmers meet regularly in water temples to manage their irrigation systems. They have done so for a thousand years. Over the centuries, water temple networks have expanded to manage the ecology of rice terraces at the scale of whole watersheds. Although each group focuses on its own problems, a global solution nonetheless emerges that optimizes irrigation flows for everyone. Did someone have to design Bali's water temple networks, or could they have emerged from a self-organizing process? Perfect Order--a groundbreaking work at the nexus of

An important and timely contribution to International Relations and political science, this is the first general analysis of deterrence since the end of the Cold War. Using non-cooperative game theory, the authors develop a new approach to deterrence (Perfect Deterrence Theory), which they apply to unilateral and mutual direct-deterrence relationships, and to extended-deterrence relationships supported by deployment policies such as Massive Retaliation and Flexible Response. The authors focus on the relationship among capabilities, preferences, credibility, and outcomes to achieve a new understanding of threats and responses. Some surprising conclusions emerge, indicating that credible threats to respond to attack can sometimes make an attack more likely, and that incredible response threats can sometimes promote peace. With the application of deterrence theory in diverse social settings, and historical examples from before, during, and after the Cold War, this book provides a welcome new examination of the subject
