Business Intelligence and Analytics systems have the capability to enable organizations to better comprehend their business and to increase the quality of managerial decisions, and consequently improve their performance. Recently, organizations have embraced the idea that data becomes a core asset, and this belief also changes the culture of the organization; data and analytics now determine a data-driven culture, which makes way for more effective data-driven decisions. To the best of our knowledge, there are few studies that investigate the effects of BI&A adoption on individual decision-making effectiveness and managerial work performance. This paper aims to contribute to bridging this gap by providing a research model that examines the relationship between BI&A adoption and manager’s decision-making effectiveness and then his individual work performance. The research model also theorizes that a data-driven culture promotes the BI&A adoption in the organization. Using specific control variables, we also expect to observe differences between different departments and managerial positions, which will provide practical implications for companies that work on BI&A adoption.

Organizational sustainability efforts focus on three main areas: people, profit, and the environment (Elkington, 1998). With an increasing emphasis on sustainable development, economic entities are concerned with achieving long-term performance, the capacity to create value and to meet the needs of interest groups (investors, employees, customers, communities, local development), but also on the development, promotion and implementation of concrete actions for environmental protection. This study aims to identify the current stage of the relationship between sustainable development and financial performance, in order to identify key elements, trends and research gaps. Based on these considerations, we performed a quantitative analysis of a sample of 62 articles from 3 databases (ScienceDirect, Scopus and Web of Science), which we subsequently studied qualitatively.
组织可持续发展的努力集中在三个主要领域:人员、利润和环境(Elkington,1998)。随着对可持续发展的日益重视,经济实体关注的是实现长期业绩、创造价值的能力和满足利益集团(投资者、员工、客户、社区、地方发展)的需求,同时也关注环境保护具体行动的制定、促进和实施。本研究旨在确定可持续发展与财务绩效之间关系的当前阶段,以确定关键要素、趋势和研究差距。基于这些考虑,我们对来自3个数据库(ScienceDirect、Scopus和Web of Science)的62篇文章进行了定量分析,随后对其进行了定性研究。

On the background of the exponential decrease of natural resources and the continuous and accentuated degradation of the quality of the environment, ensuring the sustainability of economic and social processes has become a reality of everyday life. However, the primary focus is on the degradation of the quality of the environment, which has the main effect of global warming. The idea of sustainable development is based on 3 fundamental pillars, namely the economic, the social and last but not least the environmental. In contemporary society, direct investment is often seen as a vital source for development and even sustainable development. Thus, the desire for development must go hand in hand with sustainable development, implicitly with the quality of the surrounding environment. At the level of the European Union, it is important that all member countries implement common measures on sustainable development. This is the generous context in which the paper aims to analyse the impact of environmental effects in the volume of direct investments. We will analyse the countries of European country in the period 2004-2020, and we will use the Stata program. Thus, following the running of the multiple regression equation, we found that in attracting direct investments in European country in the period 2004-2020, the environmental effects have a positive influence.

The link between fiscal progressivity and subjective well-being at global level is an issue that has hardly been considered in the literature on the Economics of Happiness. Oishi et al. (2012) is almost the only work in this field, and they concluded that those countries which had more progressive income tax systems were also happier. Our work use their definition of progressivity as the difference between the upper and lower marginal rate on income, in order to prove its relationship with subjective well-being (SWB), but we have observed that such indicator is not very significant for a sample of 111 countries. Besides, we conclude that the fact that a country's maximum income tax rate is high turns out to have a strong influence on the declared subjective well-being of its citizens. One possible explanation for it could be that they are countries with a high GDP per capita in which disposable income after taxes remains high. However, it must be taken into account that in our work we have managed to isolate the influences that the GDP per capita variable could have using the principal component analysis method.

The current global changes bring to the fore the importance of the innovation and digital transformation for economic development. Under the previous assumption, an objective evaluation of the economic growth discrepancies, considering the digitalization process, is required. The main goal of the present research is to analyse the economic growth of the European countries, based to the digitalization process, by using an input-output method. Under these circumstances, a Data Envelopment Analysis (DEA) was performed, considering the digitalization dimensions of DESI Index as input and the economic growth (annual %) as output. Based on the proposed model, the results highlighted the bidirectional relationship between economic growth and digitalization. Consistent with the research results, the European countries can be divided in two main categories: the efficient and the inefficient. On one hand, we can find the relatively efficient European states in terms of achieving the economic growth through digitalization (Ireland, Romania, Croatia and Greece). On the other hand, there is a numerous list of the inefficient ones, including important countries like Finland, Germany or France. Obviously, a remarkable aspect related to their situation is that, considering the national available inputs, an output maximization will be possible. According to the proposed model, the efficient countries can serve as peers or optimal benchmarks for solving the issue of relative inefficiency, by adapting and implementing their good practices.

The service sector has become the dominant sphere of market economies over the last forty years. The maturity of a country’s economy is directly related to the maturity of services as an economic sector. The immense growth across the service sector has also put mounting pressure on the competitiveness of service enterprises and their marketing activities. The turn of the millennium has already seen the competitive struggle affected by two crises – first, an economic one and now, one caused by the Covid-19 pandemic, which has had a great impact (not only) on the service sector. The article deals with the question of how Czech service enterprises reflect on the impact of the pandemic. The article’s aim is to find out how service enterprises perceive the impact of the Covid-19 crisis depending on their size and classification within the service sector and how they approach marketing investments during a pandemic crisis. The research is focused on service enterprises (n=90) in terms of their application of marketing processes in the conditions of the Czech Republic in the period 2020-2021. The results, based on descriptive and inferential statistics (ANOVA test in conjunction with Hochberg and Games-Howell tests, Pearson’s correlation coefficient and chi-squared test), show that smaller enterprises tend to be more affected by the effects of government measures in the context of the Covid-19 crisis than medium and large enterprises.

Greed plays an important in the fluctuations of stock prices because investors want profits irrespective of the risk taken by them. This study aims to determine, whether, in times of rising trends in the market, greediness is good for the investor or not. Secondly, investors can get high profits by beating the market or not. The already formed deciles portfolios of listed companies on NYSE, AMEX, and NASDAQ based on size and book to market value are taken from the Kenneth R. French data library from Dec 1994 to Dec 2021. Sharpe, Treynor, and Sortino ratios are used as the measure of the performance of portfolios. Ordinal logistic regression is used to calculate the probability at different benchmark levels to determine, whether the investor gets the profit by beating the market or not. The results show that the investor who used the Sharpe ratio has an average 85% probability of getting a profit of more than 75% of the benchmark of S&P-500 in all periods. Thus, the investors’ greediness is good in the long run if the investor considers total risk and can beat the market. By using the Sortino and Treynor ratio, there is an average 50% probability of achieving the profit up to the benchmark which is S&P-500. This means that the investors are not able to beat the market thus, support the efficient market hypothesis by considering the downside and market risk.
贪婪在股票价格的波动中起着重要的作用,因为投资者想要利润而不顾他们所承担的风险。本研究旨在确定,在市场趋势上升的时候,贪婪是否对投资者有利。其次,投资者可以通过战胜市场或不战胜市场来获得高额利润。根据规模和账面市值,纽约证券交易所、美国证券交易所和纳斯达克上市公司已经形成的十分之一的投资组合来自1994年12月至2021年12月的Kenneth R. French数据库。夏普比率、特雷纳比率和索蒂诺比率被用来衡量投资组合的表现。利用有序逻辑回归计算在不同基准水平上的概率,以确定投资者是否通过跑赢市场获得利润。结果表明,使用夏普比率的投资者在所有时期获得超过标准普尔500基准指数75%的利润的平均概率为85%。因此,如果投资者考虑总风险并能战胜市场,那么从长期来看,投资者的贪婪是好的。通过使用Sortino和Treynor比率,平均有50%的概率实现达到标准普尔500指数的利润。这意味着投资者无法战胜市场,因此,通过考虑下行和市场风险来支持有效市场假说。

The magnitude of the subprime crisis effects caused recessions in several economies, giving rise to the global financial crisis. The scale of this major shock and the different recovery profiles of European economies motivated this paper. The main objective is to look for evidence of contagion between the North American financial market (S&P500) and the financial markets of Portugal (PSI20), Spain (IBEX35), Greece (ATHEX) and Italy (FTSEMIB), in the South of Europe, and the financial markets of Sweden (OMXS30), Denmark (OMX2C0), Finland (OMXH25) and Norway (OsloOBX), in the North of Europe. Considering the period from January 1, 2003 to December 31, 2013, the ARMA-GARCH models were estimated to remove the autoregressive and conditional heteroscedastic effects from the time series of the daily returns. Then, the copula models were used to estimate the dependence relationships between the European stock indexes and the North American stock index, from the pre-crisis subperiod to the crisis subperiod. The results indicate financial contagion of the subprime crisis for all analyzed European countries. The North European markets intensified the relations of financial integration (both in negative and positive shocks) with the North American market, apart from the Danish against the Portuguese. In addition to the contribution made by the joint application of the ARMA-GARCH models, the findings are useful to identify channels of financial contagion between markets and to warn about the effects of possible new crisis, which will require different levels of adaptation by the companies’ financial managers and intervention by the authorities.

Emerging markets are more exposed to risk than developed markets. Therefore, they require risk management using futures market instruments. This study aims to determine the hedging effectiveness of the spot index market risks in the stock index futures market in Brazil, Russia, India, South Africa, and Turkey. Measuring the hedging effectiveness level of futures markets is vital for these countries because investors must remain in the stock markets for the sustainability of the financial markets and economies. Weekly closing data for the period from January 2009 to October 2021 were analyzed via a dynamic method referred to as flexible least squares (FLS). Although the FLS results show that futures transactions provide high hedging effectiveness for all countries within the scope of this study, country-specific conditions may reduce the hedging effectiveness.
