Also, as Pelayo and Elisenda's attitude changes from the best judgment of treating him as equal as a human being, to using him to make money, and finally to no judgment, treating him as indifferent, eventually they regard the old man as a burden.展开更多

The price is determined by two optimal stochastic control problems(mixed with optimal stopping time in the case of American option) of forward-backward stochastic differential equations.By means of backward stochastic differential equation and partial differential equation methods, we show that both bid and ask prices are closely related to the Black-Scholes risk-neutral price with modified dividend rates.The two prices will actually coincide with each other if there is no trading constraint or the model uncertainty disappears. Finally, two applications to European option and American option are discussed.展开更多

Hori et al. constructed the Bayes-Fuzzy Estimation and demonstrated that system theory can be applied to the possibility of Markov processes, and that decision-making approaches can be applied to sequential Bayes estimation. In this paper, we focus on the Natural Flowing Case within reserved judgment. Here, the possibility of oblique (or principal) factor rotation is considered as a part of the tandem fuzzy system that follows step by step for sequential Bayes estimation. Ultimately, we achieve a significant result whereby the expected utility can be calculated automatically without the need to construct a utility function for reserved judgment. There, this utility in Re-Do can be calculated by the prior utility, and that utility in Re-set does not exist by our research in this paper. Finally, we elucidate the relationship between fuzzy system theory and fuzzy decision theory through an applied example of Bayes-Fuzzy theory. Fuzzy estimation can be applied to only normal making decision, but it is impossible to apply abnormal decision problem. Our Vague, specially Type 2 Vague can be applied to abnormal case, too.展开更多

Freedom of indifference is the option to choose between opposites in a given situation. In this paper, I present the ambitious attempt of the German pre-Kantian philosopher Christian August Crusius (1715-1775) to argue for the claim that we have freedom of indifference as a matter of hypothetical necessity. The point is that, in his view, there can be no actual world without freedom of indifference. This is not a logical but a metaphysical truth. I argue that a possible (motivational) reason for CrusiusJs choice to tread this slippery path is that he attempts to bestow some metaphysical dignity on the freedom of indifference. As a consequence, this metaphysical value of freedom of indifference shapes the relation between the divine and free, rational agents in a way that is completely different from a rationalist’s conception such as Leibniz’s. In this paper, I give a plausible interpretation of a metaphysical argument that has been neglected in the relevant literature.展开更多

First, when they are pre-set, the amount of possible information about Indifferent Event tends to be large. Therefore, since the decision is risk tolerant, the Max-Product method of Tanaka et al. is used to calculate the expected utility possibility. Next, in the case of automatic derivation after the fact, the amount of information on the possibility of Indifferent Event is relatively small, so the expected utility possibility is derived using Zadeh’s Fuzzy Event Possibility Measure. Here, it is assumed that the setting of the utility function is independent of the information on the occurrence of the Indifferent Event and is identified by the decision maker by lot drawing using the certainty equivalence method. As a concrete example, we focus on the pass/fail decision of a recommendation test, which is a two choice question in the No-Data Problem, and illustrate the multistage state identification method. .展开更多

In view of their significant cost to firms, the Financial Accounting Standards Board (FASB) has mandated expensing ESOs since 2004. The main difficulty of ESO valuation lies in the uncertain timing of exercises, and a number of contractual restrictions of ESOs further complicate the problem. We present a valuation framework that captures the main characteristics of ESOs. Specifically, we incorporate the holder's risk aversion, and hedging strategies that include both dynamic trading of a correlated asset and static positions in market-traded options. Their combined effect on ESO exercises and costs are evaluated along with common features like vesting periods, job termination risk and multiple exercises. This leads to the study of a joint stochastic control and optimal stopping problem. We find that ESO values are much less than the corresponding Black-Scholes prices due to early exercises, which arise from risk aversion and job termination risk; whereas static hedges induce holders to delay exercises and increase ESO costs.展开更多

Often, legal claims of medical negligence and §1983 based on deliberate indifference by the correctional officials follow. Unique stable and dynamic factors and circumstances and their interaction explain most suicides. A systematic suicide screening using a well-designed suicide screening questionnaire that captures known risk factors will identify most inmates at risk if adequately used. Identification and subsequent mental health assessment set the stage for preventive intervention, monitoring, and treatment of the inmates. A multidimensional suicide prevention program saves not only lives but also the best defense against a liability lawsuit.展开更多
