On the background of the exponential growth of the world’s population, doubled by the decrease of natural resources and the continuous, accentuated degradation of the quality of the environment, with global warming as its main effect, ensuring the sustainability of economic and social processes is becoming a growing concern. At the European Union level, it is important that all member countries adhere to and implement common measures on sustainable development, which involve, inter alia, ensuring the convergence of policies and their effects at EU level. The EU through detailed SDGs presents the structure of a system of indicators structured on 17 objectives, indicators taken over, implemented, and calculated by EUROSTAT. The study proposes, based on a Composite Index of Sustainable Development of EU Countries’ Economies (ISDE-EU), the analysis of the convergence of the sustainability of EU states’ economies, not so much at individual level, but at cluster level, each cluster containing EU countries with similar/close ISDE-EU levels and dynamics. The results of the analysis confirm the partial existence of the beta and sigma convergence of the sustainability of EU countries’ economies. Please note that, at the time when we processed data, the UK was an EU state, which is why it was included in the analysis.

A State's GDP represents the aggregated image of economic outcomes. Both the GDP dimension and its structure constitute important information with respect to th

The main objective of this research is to identify the determining factors in the decision to open a term deposit following a telemarketing campaign carried out by a Portuguese bank. To support this objective, three secondary objectives were defined: (1) analyzing the impact of holding a personal loan or mortgage on a person s decision to access term deposits, (2) examining differences in education levels among individuals who open a term deposit, and (3) assessing the influence of individuals responses to previous bank campaigns on their decision.The study is based on data collected by a Portuguese bank during a telemarketing campaign promoting term deposits. The data was gathered between May 2008 and November 2010. To achieve these objectives, we will employ data mining techniques such as logistic regression and decision trees. The analysis classifies individuals into two categories: those who accepted and those who did not accept the bank s offer. Results indicate that call duration and the outcome of the previous marketing campaign are the most significant predictors of a customer s decision. These findings provide valuable insights for optimizing direct marketing strategies in the banking sector. Future research could enhance predictive accuracy by integrating additional variables such as financial behavior, economic conditions, and demographic factors.

Micro-zonal statistics or, simply, microstatistics is a new concept introduced by the author in 2005 and it refers to statistical information regarding socio-economic indicators structured by districts and may contribute to increase the quality of decisions made by local public administration.
