Therefore, it is of utmost importance to understand the geography of the evolution of successive pandemic waves. Particularly in European countries, where, in recent decades, more advanced models for cohesion and competitiveness of a whole with more than 400 million inhabitants have been achieved, with ambitious challenges for horizon 2030 regarding this vast territory’s economic, social, and environmental sustainability. Objective: The main objective of this research is to describe the multivariate trajectories of COVID-19 incidence, mortality, hospital admissions, ICU admissions and testing, over three successive waves, covering al...

Firstly we aimed for a deeper understanding of various aspects of well-being evolution in the last nine years using a multivariate statistical analysis of 79 indicators considered in such period. Then we approached one of the main issues usually pointed out about index construction: the use of weights for the computation of composite indexes. Using a simulation, we discussed the possible resilience of changing the weights attributed to each of the ten domains used in the construction of this index of well-being.

The dynamics of retirement pensions are usually studied in Economics using overlapping generation models. These models are based on simplifying assumptions like the use of a representative agent to ease the problem of tractability. Alternatively, we propose to use agent-based modelling (ABM), relaxing the need for those assumptions and enabling the use of interacting and heterogeneous agents assigning special importance to the study of inter-generational relations. We treat pension dynamics both in economics and political perspectives. The model we build, following the ODD protocol, will try to understand the dynamics of choice of public versus private retirement pensions resulting from the conflicting preferences of different agents but also from the coop...

SDMX Content-Oriented Guidelines (COG) recommend practices for creating interoperable data and metadata sets using SDMX technical standards, focusing on the harmonization of specific concepts that are common to a large number of statistical domains. As well as commonly understood data structure definitions (DSDs) allows mapping the exchanged data messages from and to internal statistical databases and systems, also commonly understood metadata structure definitions (MSDs) allow mapping metadata from and to statistical information systems that may be technologically or linguistic diverse. To establish these common structures, cross-domain concepts that are commonly used in SDMX messages have be...

The dynamics of retirement pensions are usually studied in Economics using overlapping generation models. These models are based on simplifying assumptions like the use of a representative agent to ease the problem of tractability. Alternatively, we propose to use agent-based modelling (ABM), relaxing the need for those assumptions and enabling the use of interacting and heterogeneous agents assigning special importance to the study of inter-generational relations. We treat pension dynamics both in economics and political perspectives. The model we build, following the ODD protocol, will try to understand the dynamics of choice of public versus private retirement pensions resulting from the conflicting preferences of different agents but also from the cooperation between them. The aggregation of these individual preferences is done by voting. We combine a microsimulation approach following the evolution of synthetic populations along time, with the ABM approach studying the interactions between the different agent types. Our objective is to depict the conditions for the survival of the public pensions system emerging from the relation between egoistic and altruistic individual and collective behaviours.
