Artificial Economics is one of the fastest growing approaches to analyse complex socio-economic systems. In this paper we present our views on the distinguishing features of Artificial Economics and on its relation with Theoretical Economics - the field that in our opinion lies closest to...

In this work we present an alternative approach to the usual graphics of time series for its comparative exploratory analysis. By having several time series measures in various contexts, we suggest its structure in multiple tables to study adequately their similarities and differences. The...

It is the purpose of this work to analyze the significance of changes in average for the collection of value-added (VAT) and income taxes from year 2000 and up to the second quarter of 2015. To accomplish that, classic methods of significance will be applied, but contrasted with tests for the...
