In advanced economies there is a tendency to move to digitization and cashless financial economic activities. In this sense, the number of cryptocurrencies that contributed more to this trend increased. In this article the authors aim to highlight the functions of money in the modern economy taking into account these trends and developments. In this sense, Bitcoin and other digital currencies can cause a change in the functions of money. In the article we sought to demonstrate the extent to which digital currencies can be considered money, using a complex methodology, logical and interpretive analyses, starting from the comparative study of the situation of coins and the existing situation in the monetary mass of the money that exists in circulation.

In this article, the authors present the results of research undertaken in relation to the situation regarding renewable and non-renewable energy reserves in the European Union, as well as the way in which this energy is consumed. The general view presented regarding energy resources around the world is that oil, natural gas and coal are being exhausted at an alarming rate and if we continue to exploit these oil resources at our current pace, we will see a massive depletion in energy resources over the next 41 years. The authors also focus on representing the intensity of greenhouse gas emissions from energy consumption, demonstrating that it has shown a slight decrease in the European Union. The resources and consumption of renewable and non-renewable energy were analyzed in close interdependence with these indicators under study, such as final energy consumption, renewable energy and total energy production, in order to give a correct interpretation of how these resources are used. At the same time, starting from the fact that the world economy is currently facing a cluster of crises (pandemic, financial-economic, energy, general resources), it was deemed important to highlight the fact that the total production of energy demonstrated an oscillating trend during this period.

The authors of this article aim to highlight how current crises (health, economic and financial, energy, food, etc.) have an effect on domestic and, especially, international affairs. At the same time, the aim is to identify and specify how the crises we are facing are jeopardizing macroeconomic stability. A number of study authors on the trend of the world economy have already stated that the world economy is practically in recession. This conclusion was reached based on the fact that, in addition to the crises affecting the world situation, the effect of the pandemic Corona virus, and the Russian-Ukrainian war (Russian-Ukrainian armed conflict) which is xpected to be long-lasting. The prospect of a Russian-Ukrainian armed conflict leads to the conclusion that, at the European Union and individual level, each and every state will face difficulties with negative effects on maintaining macro-stability and the development of domestic and international affairs at a convenient pace. In order to determine these aspects, we set out to use the widest possible methodology of international comparisons, the use of statistical indicators calculated and obtained from the European Union, Eurostat, the National Institute of Statistics and the application of statistical-econometric methods / models to obtain the parameters that will form the basis of the future comparison and, especially, of establishing the evolutionary trend of the world, European economy and, especially in this case, of Romania.

The COVID-19 pandemic crisis, which was triggered in 2019 with oscillating evolution in 2020 and 2021, was a factor that has had dramatic effects on the economic growth of countries worldwide. In the context of the pandemic crisis, population health has deteriorated; education and economic activity in all the countries around the world have been affected. The main purpose of this paper is to highlight the special situations that humanity is experiencing as a result of the unprecedented effects that the COVID-19 crisis is having on the socioeconomic evolution. Specific statistical econometric methods (such as analysis of linear correlations, multiple linear regression, analysis based on dynamics indicators, and spectral analysis, comparability based on indices) were applied to highlight the evolution and future prospects of the COVID-19 virus worldwide. The COVID-19 crisis has generated another major issue for mankind, along with global warming and the energy transition, namely, population health. For this reason, in this study, we focused on the impact of the COVID-19 crisis on population health in a broader context; the sustained growth of populations in developing countries and aging populations in developed economies.

Economic growth is a goal of every country and equally of the European Community. In this sense, all national strategies related and not subordinated to the European Union’s strategy aim at economic growth, which will ensure the improvement of the quality of life. Economic growth is always achieved by the level registered by the Gross Domestic Product (Gross Domestic Product per capita) these being the most important indicators of results calculated at macroeconomic level. The proper functioning of a country’s economy must be based, first of all, on certain correlations that are established between socio-economic variables, a context in which there must be certain proportions. The evolution of the economy in free market conditions reaches imbalances at certain times, a context in which macroeconomic stability is affected. Most often, crises, regardless of their health, economic, economic or financial nature, have the first effect of affecting macroeconomic stability. In the current conditions, when we face the health crisis, combined with the economic and financial crisis, the macroeconomic imbalance is obvious by not respecting some proportions and correlations, which must be established at the macroeconomic level. The analysis of this aspect of crises and their effect on economic correlations and macrostability is the subject of the study in this article.

Tourism is one of the consistent branches of the national economy, which can ensure some concrete results and a tailor-made contribution to the formation of the Gross Domestic Product. The tourism industry is also called invisible trade in the sense that, although it does not export goods and services, by practicing it, by developing it, it ensures consistent revenues to the state budget, but also ensures the possibility of increasing Gross Domestic Product. Analysing the current situation of the health and economic-financial crisis, it is found that in 2020 HoReCa, the tourism industry, complementary services have decreased alarmingly. Against this background, tourism has reduced its contribution to the formation of the Gross Domestic Product, which can lead to an even greater decrease. Investments in tourism are eroding. There is no possibility of refinancing despite support measures provided by the authorities. We say in spite of some measures granted because the postponement of some payments, the postponement of some credits, the transition to technical unemployment and others will be coupled later with other measures with almost devastating effect for the Romanian economy. Thus, many jobs will be lost. On the other hand, tourism companies will not be able to move from technical unemployment to normal activity and give a minimum of six months to those in this situation. The tourist market practically does not exist because there are only sequential possibilities in which it takes place, but especially under the rule of business activities, which are also considered tourist activities. The tourist activity materialized through arrivals, overnight stays, arrivals and departures has decreased steadily and this result mainly from the data subject to the study we mentioned. It is necessary to interpret these data and possibly find ways to recover.

Blockchain is a concept that tends to revolutionize the world of finance in a technological leap that allows fast, secure and decentralized transactions. The Blockchain technology is used in virtual coins (bitcoin) conditions, with a high innovation potential, applicable in various areas, with the advantage of storing databases, resulting in an unprecedented level of transparency in the private or public area. Interestingly, under the bitcoin conditions, the black chain system uses a decentralized peer-to-peer payment system. Practically, the bitcoin can be considered as the most appropriate triple game accounting system. All of these considerations are developing in the big data era, which is defined as a large, diverse, high-volume information base requiring new forms of processing. Big data is important for businesses because based on these, strategic and marketing decisions can be made to optimize the activity in the market conditions and consumer preferences. European Union directives provide for measures to ensure the development of all states and, in this context, the community. At the same time, some measures provide for a more accelerated development for states with a low accession. For this, funds have been made from which important amounts are allocated to these states. The complex development of the European Union aims, in fact, to improve the quality of life (standard of living) in all Member States. At the European community level there are databases usable in economic analyzes. Also, Eurostat is the institution with the most complex databases. Recently, the Conference of the Directors of the Institute of Statistics in the European States analyzed the perspective of calculating the indicators in the context of the big data to be implemented. The article focuses on the concrete study of the use of large data in the calculation of the indicators that underlie the comparability between the EU Member States.
