Review of 'The Outer Limits of Reason' by Noson Yanofsky 403p (2013) (review revised 2019)
I give a detailed review of 'The Outer Limits of Reason' by Noson Yanofsky from a unified perspective of Wittgenstein and evolutionary psychology. I indicate that the difficulty with such issues as paradox in language and math, incompleteness, undecidability, computability, the brain and the universe as computers etc., all arise from the failure to look carefully at our use of language in the appropriate context and hence the failure to separate issues of scientific fact from issues of how language works. I discuss Wittgenstein's views on incompleteness, paraconsistency and undecidability and the work of Wolpert on the limits to computation. To sum it up: The Universe According to Brooklyn---Good Science, Not So Good Philosophy.

Climate change in game theory
The study provides an overview of the application possibilities of game theory to
climate change. The characteristics of games are adapted to the topics of climate and carbon. The importance of uncertainty, probability, marginal value of adaptation, common pool resources, etc. are tailored to the context of international relations and the challenge of global warming
Climate change in game theory context
The aim of this paper is to survey the game theory modelling of the behaviour of global players in mitigation and adaptation related to climate change. Three main fields are applied for the specific aspects of temperature rise: behaviour games, CPR problem and negotiation games. The game theory instruments are useful in analyzing strategies in uncertain circumstances, such as the occurrence and impacts of climate change. To analyze the international playersâ relations, actions, attitude toward carbon emission, negotiation power and motives, several games are applied for the climate change in this paper. The solution is surveyed, too, for externality problem
Information, fairness, and efficiency in bargaining
Economic theory assumes people strive for efficient agreements that benefit
all consenting parties. The frequency of mutually destructive conflicts
such as strikes, litigation, and military conflict, therefore, poses an important
challenge to the field
Dynamic Non-Bayesian Decision Making
The model of a non-Bayesian agent who faces a repeated game with incomplete
information against Nature is an appropriate tool for modeling general
agent-environment interactions. In such a model the environment state
(controlled by Nature) may change arbitrarily, and the feedback/reward function
is initially unknown. The agent is not Bayesian, that is he does not form a
prior probability neither on the state selection strategy of Nature, nor on his
reward function. A policy for the agent is a function which assigns an action
to every history of observations and actions. Two basic feedback structures are
considered. In one of them -- the perfect monitoring case -- the agent is able
to observe the previous environment state as part of his feedback, while in the
other -- the imperfect monitoring case -- all that is available to the agent is
the reward obtained. Both of these settings refer to partially observable
processes, where the current environment state is unknown. Our main result
refers to the competitive ratio criterion in the perfect monitoring case. We
prove the existence of an efficient stochastic policy that ensures that the
competitive ratio is obtained at almost all stages with an arbitrarily high
probability, where efficiency is measured in terms of rate of convergence. It
is further shown that such an optimal policy does not exist in the imperfect
monitoring case. Moreover, it is proved that in the perfect monitoring case
there does not exist a deterministic policy that satisfies our long run
optimality criterion. In addition, we discuss the maxmin criterion and prove
that a deterministic efficient optimal strategy does exist in the imperfect
monitoring case under this criterion. Finally we show that our approach to
long-run optimality can be viewed as qualitative, which distinguishes it from
previous work in this area.Comment: See http://www.jair.org/ for any accompanying file
Analytic Narratives: What they are and how they contribute to historical explanation
The expression "analytic narratives" is used to refer to a range of quite recent studies that lie on the boundaries between history, political science, and economics. These studies purport to explain specific historical events by combining the usual narrative approach of historians with the analytic tools that economists and political scientists draw from formal rational choice theories. Game theory, especially of the extensive form version, is currently prominent among these tools, but there is nothing inevitable about such a technical choice. The chapter explains what analytic narratives are by reviewing the studies of the major book Analytic Narratives (1998), which are concerned with the workings of political institutions broadly speaking, as well as several cases drawn from military and security studies, which form an independent source of the analytic narratives literature. At the same time as it gradually develops a definition of analytic narratives, the chapter investigates how they fulfil one of their main purposes, which is to provide explanations of a better standing than those of traditional history. An important principle that will emerge in the course of the discussion is that narration is called upon not only to provide facts and problems, but also to contribute to the explanation itself. The chapter distinguishes between several expository schemes of analytic narratives according to the way they implement this principle. From all the arguments developed here, it seems clear that the current applications of analytic narratives do not exhaust their potential, and in particular that they deserve the attention of economic historians, if only because they are concerned with microeconomic interactions that are not currently their focus of attention
Three alternative (?) stories on the late 20th-century rise of game theory
The paper presents three different reconstructions of the 1980s boom of game theory and its rise to the present status of indispensable tool-box for modern economics. The first story focuses on the Nash refinements literature and on the development of Bayesian games. The second emphasizes the role of antitrust case law, and in particular of the rehabilitation, via game theory, of some traditional antitrust prohibitions and limitations which had been challenged by the Chicago approach. The third story centers on the wealth of issues classifiable under the general headline of "mechanism design" and on the game theoretical tools and methods which have been applied to tackle them. The bottom lines are, first, that the three stories need not be viewed as conflicting, but rather as complementary, and, second, that in all stories a central role has been played by John Harsanyi and Bayesian decision theory.game theory; mechanism design; refinements of Nash equilibrium; antitrust law; John Harsanyi
