In the conditions of a digitalized and sustainable economy, a smart decision is focused on all demand aspects regarding: the product demand, the quality demand, and the elements of national and international bodies able to ensure the criteria of economic integrity on the European Markets. These aspects represent a set of challenges and indicate the smart component of the management decision assisted by reliable economic models. The present work aims to develop such a model applied to the wheat seed production starting from the study of the specialized literature and using empirical methods. The analysis covers 2016–2020. The main objective of the study is the combination of the information from the observational study to obtain the smart decision model. The study results in the smart model of managerial decision, which represents a real necessity for managers, considering the challenges to which they are subjected. The proposed model in the paper can be used for all types of seeds across the EU and not only. The implementation of the present study by the authors validates the proposed model.

Measuring and monitoring sustainability plays an essential role in impact assessment of global changes and development. Multi-criteria decision-making (MCDM) represents a reliable and adequate technique for assessing sustainability, especially in the field of municipal buildings management, where numerous parameters and criteria are involved. This study presents an MCDM model for the sustainable decision-making, tailored to municipal residential buildings facilities management. The main outcome of this research concerned normalized and weighted decision-making matrixes, based on the complex proportion assessment (COPRAS) and weighted aggregated sum product assessment (WASPAS) methods, applied for ranking investment alternatives related to the management of the buildings. The delivered model was applied to 20 municipal buildings of Kaunas city municipality, located in Lithuania, which an EU member state employing practices and regulations in accordance with the EU acquis, as well as a former Soviet Republic. The proposed model aspires to enhance sustainability practices in the management of municipal buildings and to demonstrate a solid tool that will allow informed decision-making in the building management sector.

Crane Selection

Modular construction, which involves unit production in factories and on-site work, has benefits such as low cost, high quality, and short duration, resulting from the controlled factory environment utilized. An efficient tower crane lifting plan ensures successful high-rise modular project completion. For improved efficiency, the lifting plan should minimize the reaching distance of the tower crane, because this distance directly affects the tower crane capacity, which is directly related to crane operation cost. In situations where units are lifted from trailers, the trailer-to-tower crane distance can have a significant impact on the tower crane operation efficiency. However, optimization of this distance to improve efficiency has not been sufficiently considered. This research proposes a genetic algorithm optimization model that suggests optimized tower crane and trailer locations. The case study results show that through the proposed model, the project manager can reflect the optimal location selection and optimal tower crane selection options with minimal cost.

Yang and Qiu proposed and reframed an expected utility–entropy (EU-E) based decision model. Later on, a similar numerical representation for a risky choice was axiomatically developed by Luce et al. under the condition of segregation. Recently, we established a fund rating approach based on the EU-E decision model and Morningstar ratings. In this paper, we apply the approach to US mutual funds and construct portfolios using the best rating funds. Furthermore, we evaluate the performance of the fund ratings based on the EU-E decision model against Morningstar ratings by examining the performance of the three models in portfolio selection. The conclusions show that portfolios constructed using the ratings based on the EU-E models with moderate tradeoff coefficients perform better than those constructed using Morningstar. The conclusion is robust to different rebalancing intervals.

AbstractThis article explores issues of energy supply security from the perspective of the EU–Russian energy relationship and of competing foreign energy policy paradigms. Using approaches developed by Peter Rutland within the context of Russia's energy policy towards the CIS and the three pillars of EU energy policy as a starting point, the article concludes that the overall EU–Russian energy relationship can be best explained through a framework of mutual interest and dependency: that is, the EU is becoming increasingly, but not totally, dependent on Russian energy, particularly gas; and Russia is becoming increasingly, but not totally, dependent on European markets. Nevertheless, other paradigms continue to yield useful insights in relation to individual components of the EU–Russian energy relationship.

This chapter analyzes the differences of decision-making process in the EU member countries, caused by differences in main dimensions of national culture of each of them. The influence of different cultural dimensions on decision-making process is explained. Thanks to the application of qualitative research method and deductive approach, there are conclusions about specificities of decision-making process, in particular EU countries. Using the inductive approach, content analysis method and method of synthesis, the EU countries were grouped regarding to the decision-making styles that are the most appropriate in each of them, based on the characteristics of the cultural framework that exist within them. Obtained results may help managers to better understand their decision-maker role in different cultural environment and it would enable them to apply the appropriate decision-making style, which would increase the quality of business decisions that are being made.

Decision Making Processes

The COVID-19 pandemic accelerated trends to digitalization and automation, which allow us to acquire massive datasets useful for managerial decision making. The expected increase of available data (including big data) will represent a potential for an increasing deployment of management decision support systems for more general and more complex tasks. Sophisticated decision support systems have been proposed already in the pre-pandemic times either to assist managers in specific decision-making processes or to perform the decision making fully automatically. Decision support systems are presented in this chapter as perspective artificial intelligence tools contributing to a deep transform of everyday management practices. Attention is paid here to their new development in the quickly transforming post-COVID-19 era and to their role under the post-pandemic conditions. As an original contribution, this chapter presents a vision of information-based management, which far exceed the rather limited pre-pandemic visions of evidence-based management focused primarily on critical thinking.

Abstract The ongoing crisis in the euro zone raises the question of whether the previously chosen path of European integration is likely to spur internal and external competitiveness and capability of action. In economic terms, it is about a strategy that does justice to the uniqueness of the landscape of European markets. Its special feature is that Europe – in contrast to North America – has developed diverse economic cultures historically whose qualities match the requirements of distinct markets and whose set of institutions are functional. An adequate European economic policy has to acknowledge these cultures and develop strategies to improve their individual effectiveness, i.e. comparative institutional advantage. This productive governance (Ordnungspolitik of the visible hand) is in stark contrast to a policy of harmonization that emanates from the idea of uniform market conditions. The attempt to integrate Europe on the basis of a “multi-speed” model has failed. The essential task now is to take into account the diversity of economic cultures in Europe and to unite the continent along a variety of paths. What the EU needs are rules and strategies that create unity in diversity, realizing its official motto: united in diversity. What Europe needs is an integration strategy on several paths – not only at several speeds. JEL Codes: F15, F53

Purpose This study aims to examine the relation between illiquidity, feedback trading and stock returns for several European markets, using panel regression methods, during the financial and the sovereign debt crises. The authors’ interest here lies twofold. First, the authors seek to compare the results obtained here under crisis conditions with those in the existing literature. Second, and of greater importance, the authors wish to examine the interaction between liquidity and feedback trading and their effect on stock returns. Design/methodology/approach The authors jointly model both feedback trading and illiquidity, which are typically considered in isolation. The authors use panel estimation methods to examine the relations across the European markets as a whole. Findings The key results suggest that in common with the literature, illiquidity has a negative impact upon contemporaneous stock returns, while supportive evidence of positive feedback trading is reported. However, in contrast to the existing literature, lagged illiquidity is not a priced risk, while negative shocks do not lead to greater feedback trading behaviour. Regarding the interaction between illiquidity and feedback trading, the study results support the view that greater illiquidity is associated with stronger positive feedback. Originality/value The study results suggest that when price changes are more observable, due to low liquidity, then feedback trading increases. Therefore, during the crisis periods that afflicted European markets, the lower levels of liquidity prevalent led to an increase in feedback trading. Thus, negative liquidity shocks that led to a fall in stock prices were exacerbated by feedback trading.
