Since its evolution, the concept of Entropy has been applied in various fields like Computer Science, Quantitative Finance, Physics etc. The definition of Entropy has slightly different meanings depending on the field of science to which it is being applied. This paper aims to examine the...

This paper describes some analytic simulation experiments performed on a nonlinear macroeconometric model of the Italian economy. The proposed techniques extend to nonlinear models methods that are available, in the literature, for linear econometric models. The results can be profitably used...

A model of Markov dependent trials is considered that leads to a generalization of the binomial distribution in the context of evaluating models of a time series by exploiting the sequential nature of model-based predictions. Adopting an evaluation method similar in nature to that suggested by...

A microeconomic model is developed, which accurately predicts the shape of personal income distribution (PID) in the United States and the evolution of the shape over time. The underlying concept is borrowed from geo-mechanics and thus can be considered as mechanics of income distribution. The...

The assumption we submit, because macroeconomic forcasts would be unperfect, is that behavioral equations doesn't enough describe economic behaviours through the capacity of reaction opposite to environment. Further, the forcaster belongs to his search-system, so that, may be, we must now...

The trade off between investing in energy savings in single family houses and investing in more expensive heating technologies with low variable costs has been modelled for a number of building and consumer categories in Denmark. The households have an option to combine their primary heating...

The Lucas critique has exposed the problem of the trade-off between changes in monetary policy and structural breaks in economic time series. The search for and characterisation of such breaks has been a major econometric task ever since. We have developed an integral technique similar to CUSUM...

One can compare Econometrics with an Art which tries to minimize the lag between a quantitative law and a sample of data. Hence, the econometrics teaches us that before to built models, we must built data bank through strict procedures to prevent errors. Our paper presents classical methods to...

Okun’s law for the biggest developed countries is re-estimated using the most recent data on real GDP per capita and the rate of unemployment. Our results show that the change in unemployment rate can be predicted with a high accuracy. The link needs the introduction of a structural break...
