We show that an increase in uncertainty about the probability of being audited (ambiguity) increases tax compliance for ambiguity-averse taxpayers but reduces compliance for ambiguity lovers. Because experimental evidence reveals considerable heterogeneity with respect to ambiguity preferences, we conclude that fostering uncertainty about the probability of being audited may not be an effective...

ambiguity is one of very important techniques in persian rhetoric, but in spite of its importance, it seems there is not enough accuracy in its definition and types.  the present essay tries to redefine the concept of ambiguity. we will begin by analyzing the definitions of ambiguity and amphiboly according to the old and new persian sources; then we presents a new definition and review and ana...

Why don’t people in developing countries insure themselves? I propose that some households are ambiguity averse, and that these households fear any insurance contract they purchase will payout when it is not needed and will not payout when it is. I study two applications of this observation. I first study formal crop insurance, in particular index insurance and the insurance element of limited ...

The order relation of fuzzy number is important in decision making and optimization modeling, and ranking fuzzy numbers is difficult in nature. Ranking trapezoidal intuitionistic fuzzy numbers (TrIFNs) is more difficult due to the fact that the TrIFNs are a generalization of the fuzzy numbers. The aim of this paper is to develop a new methodology for ranking TrIFNs. We define the value-index an...

| We present results concerning three diierent types of quartic (fourth order) time-frequency distributions. First, we present new results on the recently introduced local ambiguity function, and show that it provides more reliable estimates of instantaneous chirp rate than the Wigner distribution. Second, we introduce the class of quartic, shift-covariant, time-frequency distributions, and inv...

The paper investigates the properties of ambiguity functions of 2-D analytic, quaternionic and monogenic signals. In the introduction the notions of the above signals and their Wigner distributions and ambiguity functions are recalled. The properties of the ambiguity functions are investigated using two kinds of test signals: A band-pass test signal in the form of a sum of two harmonic signals ...

AbSlracl: Algorilhms for providing a quanlitati\e measure of edge ambIguity are described through fuzzy measures in a set. An IOdex is derined whose value IS maximum fOJ a grey lone image and decreases as the fnzzmess In detecting edges decreases. The inherent fuzzifying properly of the S-funclion is found to enable one nOI 10 use the tNT operator for contrasl enhancement and 10 save the time o...

The connection between the Wigner function and the generalized OTF, and between the ambiguity function and the generalized OTF is investigated for non-paraxial scalar wavefields. The treatment is based on two-dimensional (2-D) wavefields for simplicity, but can be extended to the three-dimensional case.

We propose iterative, adaptive trellis-based blind sequence estimators, which can be interpreted as reduced-complexity receivers derived from the joint ML data/channel estimation problem. The number of states in the trellis is considered as a design parameter, providing a trade-off between performance and complexity. For symmetrical signal constellations, differential encoding or generalization...

In this paper, considers the usage of intuitionistic fuzzy numbers in decision making. The values and ambiguities of the membership degree and the non-membership degree for trapezoidal intuitionistic fuzzy number are defined as well as the value-index and ambiguity-index. The proposed ranking method is easily implemented and has a natural interpretation. 2010 AMS Classification: 47S20, 03E72
