A robust definition of possibility for biseparable preferences
No full textThis note presents several preference-based definitions of a likely event, and shows that they induce (in the sense of Lo 2005b) the same set of possible states for biseparable preferences.

Although these labels could not be archived as the legitimate designation of types as they are not effectively published (see Art. 7.10 of the ICN), they supposedly reflect the original author’s intention and are thus adopted here.

Possibility and permissibility
No full textWe generalize permissibility (Brandenburger, 1992) to allow for any suitably defined model of preference and definition of possibility. We also prove that the generalized solution concept characterizes rationality, caution, and “common belief" of rationality and caution.
Essays in Incomplete Information and Trade Policy
No full textStrategic trade policy has been one of the most intensively researched areas in theory of industrial organization and international trade over the last three decades. The fundamental motivation is that governments adopt trade polices to confer strategic advantage to their respective domestic firms when firms are imperfectly competing with each other. However, most of existing literature focuses on markets with certainty and complete information among firms. This dissertation introduces incomplete information at industrial level into uncertainty markets in various trade models, and it also integrates the concept of option value from financial economics into equilibrium analysis.
In Chapter 1, incomplete information at industrial level is introduced into an importing country model in which the domestic market demand is uncertain, and the policy is chosen before the uncertainty is resolved. Unlike the classical findings on the issue of equivalence of tariffs and quotas under certainty and complete information, it is shown that a tariff is superior to a quota regardless of the degree of uncertainty. Moreover, a prohibitive quota that results in autarky is always preferred to a quota at the free-trade level as long as quota is concerned.
Chapter 2 studies the design of trade policies in an uncertain third market with incomplete information. It is shown that the country with firm having information disadvantage tends to choose the direct quantity control, while the country with well-informed firm would use export subsidy (export quota) when the degree of uncertainty is sufficiently high (low).
Finally, Chapter 3 extends the conventional literature on strategic trade policy in reciprocal dumping model to the context that involves market demand uncertainty and incomplete information. Incomplete information at industrial level redistributes the option value associated with better information to the country with well-informed firm. As a result, both governments tend to choose tariffs over export subsidies in the Nash equilibrium of the simultaneous strategic trade policy games under complete and incomplete information. This yields a second best outcome. Moreover, Nash equilibrium outcome is shown to be inferior to free-trade outcome

A Study on “Jen Chung” Images of Vairocana Dharmakaya
No full textThe term Jên-Chung images (Jên-Chung meaning “in one's body”) is found in such old Chinese Buddhist manuscripts as the Liao Kao Sêng Chuan (Biographies of High Priests, written in the Liao period) and the Lo Yang Ch'ieh Lan Chi (Record of Buddhsti Temples in Lo-yang). Because mentions in these manuscripts lack concrete descriptions, it has been unknown what sort of images they were and in what form. The Jên Chung images, which were widely known during their times but which were forgotten in later periods, have attracted the author's deep interest.
His first approach to the interpretation of this term was through literary sources, which has led him to the conclusion that it is an abbreviation of “Lu-shê-na Fa-chieh Jên-chung” image (Jên-chung images of Vairocana Dharmakaya), and denotes a peculiar type of Vairocana inage with illustration of the Atavamsa Cosmos in its body (Figs. 1-15). Examples of this type have been known in East Turkestan and Tun-huang, and the author has added some more through his studies on literary sources, establishing that the Jên-chung type was transmitted during the early fifth century from East Turkestan through Tun-huang and Ho-hsi to China Proper, where it was in use until the end of the Tsang period. He has thus succeeded to clarify the situation of Jên-chung images in the history of Chinese Buddhist art.
According to his interpretation, the principal statue in Cave No. 18 of Yün-kuang Cave Temple is a Jên-chung image (a Vairocana image), though this theory has been denied by other experts. He believes that this conclusion involves various problems concerning the eastward spread of Atavamsa teachings as well as the character of Northern Wei Buddhism.journal articl
Correlated Nash Equilibrium
No full textNash equilibrium presumes that players have expected utility preferences, and therefore the beliefs of each player are represented by a probability measure. Motivated by Ellsberg-type behavior, which contradicts the probabilistic representation of beliefs, we generalize Nash equilibrium in n-player strategic games to allow for preferences conforming to the maxmin expected utility model of Gilboa and Schmeidler [Journal of Mathematical Economics, 18 (1989), 141–153]. With no strings attached, our equilibrium concept can be characterized by the suitably modified epistemic conditions for Nash equilibrium.Agreeing to disagree, Correlated equilibrium, Epistemic conditions, Knightian uncertainty, Multiple priors, Nash equilibrium
