The purpose of this research work is to find a methodology for the strategic development of competitive advantage for information technology (IT) companies (Mezger and Violani, 2011). The ultimate aim of this project is to develop a methodological approach on this issue, based on dynamic simulation models (DSM) (Wirahadikusumah and Abraham, 2003). With the aid of DSM, senior managements of organizations will have the opportunity to make decisions of assured success. This success shall be guaranteed by the realization of entrepreneurial activity in a safe and inexpensive computing environment before actual investment.

This paper highlights the advantages of the dynamic modelling of systems aiming at developing competitive advantage for IT companies (Ordóñez de Pablos, 2006). In this research, we have used the science of design and the research methodology for testing the concept of modelling as well as the process of modelling. The models have been completed through a series of alternations and iterations in the design, development, simulation, testing and evaluation.

This paper examines the interface among several dimensions for the development of dynamic models. The validity and usefulness of those models in the process of decision-making has been confirmed by the usage of dynamic models in various sectors.

This paper applies the system and the concepts of dynamic modelling, which are pioneering elements as to their nature and evolution. Although the sector, where the modelling was applied, is an IT company, the concepts and principles investigated, developed and validated can be applied to most enterprises.

In this chapter, we investigate the interactions between governance quality and economic development. More specifically, we analyze how the institutions through which state authority is exercised influence the level of economic development. In that respect, governance could be considered as a quasi-factor of production which affects the country's economic growth and development, an issue that lies in the heart of institutional economics. The effect of governance on economic development is mainly played out via two channels. Namely, the quality of democracy, distinguished in political rights and civil liberties, and the level of corruption, associated with the exercise of state authority. Good governance is in principle associated with a high quality of democracy and a low level of corruption. Both generate positive effects on the level of economic growth and development, mainly due to their impact on state effectiveness and private and public investment. At the same time, there also exists an inverse causality: the level of economic development affects positively the quality of democracy and negatively the level of corruption which in turn tend to improve the quality of democracy. These coexistent mechanisms are associated with crucial policy issues which are largely neglected by the traditional theory of economic growth.

This paper explores the fragmented social policy choices imposed in Greece during the turbulent period 2010–2020. The institutional, political, and economic crisis brought in the enforcement of huge austerity reforms provoking deep socioeconomic devaluation: in GDP, in available income, in job opportunities, in living standards, in social protection. The decade is marked by a couple of mismatches diminishing welfare provision and mounting social need, inexpedient national administration, and unbalanced international intervention. A major cause of the national bankruptcy has been the stark imbalances of a residual social policy system which never aimed at tackling inequalities, challenging market outcomes, or fighting poverty. A fractured system distributing welfare according to individualistic/corporatist criteria, preserving a clientelistic/corrupting pattern, focusing upon an unfair/irrational pension provision. At a first sight, the urgent changes during the crisis have reinforced residualism, deregulated social/labor rights, reproduced inadequacies, exacerbated the discontinuities with the European Social Model. At a second reading, they have also recalibrated the system embracing elements of universality, unity, rationality, sustainability, and equity. In sum, the 2021 social policy starting point provides modest protection and keeps complexities, contradictions and controversies. The crisis imposed a welfare strategy of cuts that has produced less provision, stricter conditions, more harmony, dubious viability, dribs, and drabs of justice. The pandemic health crisis gives now prominence to the neglected but crucial role of the NHS and, in a broader sense, to the vital importance of institutionalised welfare provision.

The tourism industry in Greece has come a long way since its beginning as a distinct economic activity to reach the recent impressive results. It is a sector that has grown remarkably and became a major source of growth for the Greek economy. As such this chapter aims to discuss the importance and the potential of the sector, the unique characteristics of the Greek tourism industry and the future challenges ahead. Tables and suitable graphics are provided to visually enhance and inform the discussion. A wide range of articles, journals, books, and electronic sources has been reviewed to present as accurately and up to date information as possible. This chapter can therefore prove useful for academics and non-academics to use it as a reference point for the tourism sector in Greece.

With its presence, which can create inefficiencies, uncertainties and risks, information asymmetry poses a significant challenge to successfully managing the agri-food supply chain (AFSC). Understanding the variables that influence information asymmetry is crucial for devising more effective strategies to mitigate it. This study, therefore, explores the variables that influence information asymmetry in the AFSC.

A qualitative analysis was conducted, relying on semi-structured interviews with 17 experts representing different actors in the AFSC (e.g. seed producers, retailers, etc.) in Germany. The collected data was analysed using the GABEK® method.

The study confirms that the influencing variables derived from the existing theory, such as price performance, digitalisation, environmental, process and quality measures, contribute to information asymmetry. It further reveals new variables that associate with information asymmetry, including documentation requirements, increasing regulation, consumer behaviour, incorrect data within the company as well as crises, political conflicts and supplier–buyer conflicts. Furthermore, the study shows that supply chain actors counteract asymmetry by focusing on social behaviour and monitoring suppliers through key performance indicators, employees and social aspects.

The study was limited to the universal influence of the variables on information asymmetry in the AFSC, making the magnitude of the influence and its context-specific nature unexplained.

This study is one of the very few that examines information asymmetry across the AFSC from the perspective of different actors, providing a more overarching and deeper understanding of information asymmetry.
