This paper analyses the impact of fiscal imbalances on expectations for an emerging economy with inflation targeting. In particular, based Colombian experience, we build a credibility index and evaluate its 2004-2019 period. To analyse monetary interactions, propose econometric model use OLS GMM methods. The results show that loss credibility, associated divergences between deficit agents’ ex...

The formation of macroeconomic policy is conceptualized as on-going process of interaction between private individuals and a centralized policymaker. This interaction is inherently strategic in nature and lends itself to a gametheoretical treatment. Starting from the basic principle of rational expectations, the analysis advances a theoretical perspective on the related concepts of macroeconomi...

Absurd? Yes. However, this false belief – that children are somehow naturally more able to use technology and are also somehow more Internet savvy – is a common one. Problems with Internet information and in more traditional forms of information are well documented. Professors of entering college undergraduates observe that students “are ill prepared to function in a technological and informati...

In this paper, the utility of credibilistic critical values in crisp conversion of fuzzy data sets is considered. Conversion of this type becomes essential mainly when clustering of fuzzy data sets is carried out. In this paper performance of two popular clustering algorithms namely Fuzzy c–means and Fuzzy c–medoids algorithms are evaluated under credibilistic critical value crisp conversion is...

Decision support systems (DSS) are beginning to use content sourced from social networks such as Twitter to provide decision makers with information to make timely and critical decisions. Misleading information obtained from Twitter can lead to adverse outcomes as well as cause trust issues within DSSs. In this paper, we propose and investigate a context-aware Twitter validator (CATVal) system ...

With both the improvement of the technology and the formalization of final user needs, distributed architectures have become common both for control and measurement applications. The credibility of the information got from this distributed architectures is not easy to point out. Several aspects need to be taken into account, relative to processing which are done on the information on various pl...

The reliability of a system is often referred to as a quality index reflecting the capability of the system to complete the specified function within specified time in reasonably satisfactory manner under the specified conditions (including hard conditions: say, operating environments, input materials and soft conditions: say, system management and operator team, and computerized monitoring ato...
