In continuation of our previous study (A. Sathyavathi (2023). Analysis of the General Administration Management Expenditure of the Bangalore Municipal Corporation https://www.ssrn.com/abstract=4403863 ; http://dx.doi.org/10.2139/ssrn.4403863 ) we propose to further analyze the sample of the...

The paper deals with models and methods for evaluation of efficiency and performance of production units. Especially, it aims at data envelopment analysis (DEA) models, which are based on the definition of efficiency as the ratio of outputs produced by the unit on the one hand and inputs spent...

The topic of this paper is evolutionary-economic models and how they are implemented in a new, effective system for programming and simulating such models. The evolutionary-economics simulation models are exemplified by the Nelson and Winter family of models of Schumpeterian competition in an...

A case is made that today's graduate students in economics must master early on a computational environment suitable for their research needs. The virtues of Mathematica for this purpose are highlighted. Descriptions of its elements that are particularly suited for this need are given along with...

In the present paper we introduce and study a generalization of the Hukuhara differ- ence and also generalizations of the Hukuhara differentiability to the case of interval valued functions. We consider several possible definitions for the derivative of an interval valued function and we study...

The LU-model for fuzzy numbers has been introduced in [4] and applied to fuzzy calculus in [9]; in this paper we build an LU-fuzzy calculator, in order to explain the use of the LU-fuzzy representation and to show the advantage of the parametrization. The calculator produces the basic fuzzy...

We propose a generalization of the Hukuhara difference. First, the case of compact convex sets is examined; then, the results are applied to generalize the Hukuhara difference of fuzzy numbers, using their compact and convex level-cuts. Finally, a similar approach is seggested to attempt a...

In this paper we illustrate the LU representation of fuzzy numbers and present an LU-fuzzy calculator, in order to explain the use of the LU-fuzzy model and to show the advantage of the parametrization. The model can be applied either in the level-cut or in generalized LR frames. The hand-like...

This document presents a set of indicators designed to measure the credit risk implicit in the deposits maintained by domestic financial institutions in foreign countries. It discusses the theoretical definition of the indicators, the software implementation and a case of study based on the...
