Annotation:  It may be said that COVID-19 eased the nature from human pollution. Present paper may argue this perception by analyzing the connection between the economic impact before and after the COVID-19 outbreak, measured by national GDP and the level of pollution in the European countries, referring to air and water pollution. A simple linear regression model with two control variables was applied in order to obtain the results (the control variable were the number of COVID-19 cases and the austerity measures applied in the countries, in the specified period, classified by the impact over the labor productivity).

Annotation: The Lucas Critique has attracted discussion since it was published in 1976. This article evaluates its impact on the epistemology of Macroeconomics. It probes deeper than an analysis on Rational Expectations into a debate on theory and practice in macroeconomics. The originality of the research concerns the convergence/divergence between the Keynes and Lucas critiques of econometrics/econometric policy. The paper updates and refines Lucas’s contribution to econometric policy evaluation framed by the Keynes – Tinbergen – Friedman – Lucas literature. The exegesis uses the expertise of the authors (one a cybernetician and one a macroeconomist) to provide a novel and stimulating platform for further debate.

Annotation: The technological ascension represents one of the main phenomena encountered by today’s society, influencing almost every field of activity of the modern world. In fact, technology has become part of our daily life, whether we refer to active participation in society, learning, work, or other activities. In order to gain a favorable position compared to other states considered as global powers, the European Union is constantly striving to advance in various fields, placing special importance on the digitalization of the Member States. In addition to the technological side, the process of digitalization takes place with and through the human factor. Thus, we are concerned with the human capital and its digital competences, as their deficiency or absence can have negative effects both on the general life chances of citizens and on the digital progress of EU Member States.
