Market Exchange Modelling Experiment, Simulation Algorithms, and Theoretical Analysis

The purpose of this paper is, through a system of software, to analyze some theoretical aggregate models. We suggest to build a disaggregated model to compare its results with these of the aggregated one. The disaggregated model uses an analogical mechanism of the individual behaviors so that a validation of it by experiments is possible. We apply the system to the mechanism of prices and we do experiments at school, which unable the Mises-Hayek-Lange debate to be reconsidered through the computer implementation of its system.Economic Modelling ; Simulation ; Planning vs Market ; Economic Software ; Experimental Economics

Learning-Testing Process in Classroom: An Empirical Simulation Model

This paper presents an empirical micro-simulation model of the teaching and the testing process in the classroomH. It is a non-econometric micro-simulation model describing informational behaviors of the pupils, based on the observation of the pupils’ communication behavior during lessons and tests. The representation of the knowledge process is very simplified. However, we tried to study the involvements of individual motivation, capability and relationship with other pupils of each pupil, to compare them to the new-classical(and keynesian) and Austrian information and knowledge theoretical results. It is a first step and future development should concern expectation behaviors and dynamics. This paper aims too to give, we hope so, some criteria of pupils’ rationality in the classroom.Teaching ; Learning ; Cheating ; Information ; Communication ; Knowledge ; Micro-simulation ; Classroom

Numerical Analysis in Econom(etr)ic Softwares: the Data-Memory Shortage Management

The econometricians and the economic modelers have to know and use numerical analysis not only to have a good understanding of their results, but sometimes to built their own tools. The increasing tendency to the use of large-scale models leads the softwares to reach the limit of the saturation of the Data-Memory. In this paper, we present an intuitive procedure DMT - i.e. Disk-Matrix Technique - which could help econom(etr)ic software developers to correct the problem of the data-memory shortage during the building of their own software.Algorithms ; Numerical Analysis ; Econom(etr)ic Softwares ; Operating System ; Data-Memory ; Data Storage

Quantitative Economic Modeling vs Methodological Individualism ?

During a long time, the Austrian Economic School was against any mathematical formalization in social and economic sciences because it would be opposed to an individualist point of view of social phenomenons. We try to find an quantitative individualism modelling way from a criticism of holist modelling. But this paper tries to improve the dilemma of the quantitative modelling : we have to choose between whole representations - which denies individuals - and individualist models which are'nt able all to represent. Each one of these models have got his own logic of elaboration (statistical, experimental etc.) but we have to consider they are complementary from a scientific point of view.Methodological Individualism ; Austrian Economics ; Quantitative Economics ; Computational Economics

Network structure of phonographic market with characteristic similarities between musicians

We investigate relations between best selling artists in last decade on phonographic market and from perspective of listeners by using the Social Network Analyzes. Starting network is obtained from the matrix of correlations between the world's best selling artists by considering the synchronous time evolution of weekly record sales. This method reveals the structure of phonographic market, but we claim that it has no impact on people who see relationship between artists and music genres. We compare 'sale' (based on correlation of record sales) or 'popularity' (based on data mining of the record charts) networks with 'similarity' (obtained mainly from survey within music experts opinion) and find no significant relations. We postulate that non-laminar phenomena on this specific market introduce turbulence to how people view relations of artists.Comment: 15
