This paper argues that the introduction of a short-sale constraint in the ArrowRadner framework invalidates standard definitions of complete and incomplete markets. In this constrained set-up, two threshold values with familiar properties arise. The case of a zero short-sale bound set on some security fulfills the standard definition of “incomplete” financial markets. Beyond a particular level ...

We show how a collection of results in the literature on the empirical estimation of welfare indicators from sample data can be unified. We also demonstrate how some of these ideas can be extended to empirically important cases where the data have been trimmed or censored.

I T HAS BEEN well known for many years that the sera of patients with certam viral infections, acquired hemolytic anemia or other disorders may contam large quantities of proteins capable of directly agglutinating normal human erythrocytes during cold incubation.1’2 These proteins are designated pathologic “complete” cold agglutinins. The direct agglutination they produce is readily reversed by...

This is a study of incomplete neutralisation using Fuzhou tone sandhi as a test case. In Fuzhou Min, Tone 44 and Tone 232 undergo putative neutralisation into Tone 53 preceding a set of low tones, while T44 and T53 are neutralised into T44 preceding T53. Data from 10 Fuzhou speakers show the former neutralisation to be acoustically incomplete, with the sandhi tone of underlying Tone 44 having a...

Mutual information is widely used, in a descriptive way, to measure the stochastic dependence of categorical random variables. In order to address questions such as the reliability of the descriptive value, one must consider sample-to-population inferential approaches. This paper deals with the posterior distribution of mutual information, as obtained in a Bayesian framework by a second-order D...

This paper proposes that secondary unlicensed users are allowed to opportunistically use the radio spectrum allocated to the primary licensed users, as long as they agree on facilitating the primary user communications by cooperating with them. The proposal is characterized by feasibility since the half-duplex option is considered, and incomplete knowledge of channel state information can be as...

We present a generalization of Levesque's logic All I Know by presenting it as an extension of usual modal logics. We study how logic All I Know can represent complete and incomplete knowledge in Logical Information Systems. In these information systems, a knowledge base is a collection of objects (e.g., les, bibliographical references) described in a logical way, furthermore in the same logic ...

Abstract—It is well known that the Analytic Hierarchy Process (AHP) of Saaty is one of the most powerful approach for decision aid in solving of a multi criteria decision making (MCDM) problem. Several computing weights methods in AHP are analyzed. Based on least square method, three methods for calculating weights using the least the sum of squares of error criterion, the least the sum of erro...

This paper presents a method for performance evaluation, ranking and clustering based on the double-frontier view to analyze the complex networks. The model allows us to open the structure of the “black box” and can help to obtain important information about efficient and inefficient points of the system. In this paper, we consider a three-stage network, in respect to the additional desirable a...
