Τεκμήριο Are acquiring firms better off after an acquisition? Evidence from a knowledge-intensive industry in Greece(2011-07) Pazarskis, Michail; Alexandrakis, Alexandros; Notopoulos, Panagiotis; Kydros, DimitriosThis study examines the impact of mergers and acquisitions (M&As) on the post-merger operating performance of merger-involved firms in Greece at information technology industry, a knowledge-intensive industry. Using accounting data (financial ratios), the post-merger performance of all the Greek companies, listed on the Athens Stock Exchange at information technology industry, that executed one merger or acquisition in the period from 2004 to 2007 as acquirers (a sample of five firms), is investigated and the degree their successful knowledge transfer to the new merged firm is evaluated. For the purpose of the study, a set of eleven ratios is employed, in order to measure acquiring firms’ operating performance and to compare pre- and post-merger operating performance for two years before and after the M&A announcements. The results revealed that M&As had a negative impact on the post-merger performance of the mergerinvolved firms from a knowledge-intensive industry, concerning their total debt analysis, two years after the M&A transaction. Also there were not some other positive or negative impacts at any other examined ratio, which reveals a possible successful transfer of knowledge, but not the creation of potential synergies or cost reductions.Τεκμήριο The Economic Crisis (2008) and Effects on Income. The Case of Greece(2015) Magoulios, George; Kydros, Dimitrios; Athianos, StergiosThis paper investigates the impact on income from the economic crisis of 2008, especially in the case of Greece. We outline literature results relating to income effects of economic crises in various parts of the world in general and the recent economic crisis in particular. What if revealed is that crises always affect the distribution of income and aggravate the problem of poverty, since the weight tends to be unevenly distributed. During the recent economic crisis, risk of poverty has increased, employment prospects are deteriorating and fiscal consolidation measures tend to reinforce inequality. Based on the results of an empirical investigation of secondary data on the income tax and its share on professional and income groups, we study the effects of the economic crisis and the measures implemented to deal with it in Greece. During the recent crisis in Greece, despite the reduction in income, total tax burden was increased due to the increased share of indirect taxes in total tax revenue. Furthermore the share of wages on GDP declined dramatically. It is the lower income groups that shouldered the brunt of fiscal adjustment. After the applied measures, a redistribution of income from the middle and mainly from low to high and very high income groups is recorded, despite the fact that wages and salaries, much less than corporate profits, contribute to overall inequality mainly due to tax evasion. The main mechanism responsible for unequal income distribution involves anti-development and anti-social austerity measures (fiscal and institutional arrangements to enhance labour market flexibility, etc.) implemented under the Memorandum, which led to an increase in the tax burden, mostly of lower incomes, a reduction on available income of households and a deterioration in indicators of economic and social welfare, income inequality and absolute poverty. The economic crisis and the measures implemented to deal with it in Greece, as in other regions of the world in the past and today, is utilized for a high-intensity (in size) and area (in the range of social groups affected) redistribution of wealth, through which the poor become poorer and the rich richer. The European strategy to address the crisis in the Eurozone and especially in Greece reinforced the inequalities and therefore operates as an obstacle to economic recovery and the equitable sharing of its results.Τεκμήριο Homer's Iliad – A Social Network Analytic Approach(2015-03) Kydros, Dimitrios; Notopoulos, Panagiotis; Exarchos, GeorgiosIn this paper we provide some insights in Homer's Iliad from the perspective of social network analysis. We use the original text and other public available data to create a social network (i.e. a graph) that comprises of all actors in the Iliad together with their interactions. We present some visualizations of these data and discuss concepts like connectivity, connected components and groupings. Furthermore, we calculate some well-established metrics, coming from social network analysis in this social network and discuss the numerical results. These results indicate that the Iliadic network is a small-world network, rather dissasortative and relatively easy to disconnect.Τεκμήριο IFRS adoption effects in Greece: evidence from the IT sector(2011) Pazarskis, Michail; Alexandrakis, Alexandros; Notopoulos, Panagiotis; Kydros, DimitriosFrom January 2005 all the listed firms in the EU member states were required to prepare their financial statements according to the International Financial Reporting Standards – IFRS. In Greece, this transition from Greek GAAP to IFRS may have an effect on firms’ financial results. This study examines the possible impact of adoption of IFRS at Greek firms of the Information Technology (IT) sector, listed on the Athens Exchange. For this reason, the study analyses the financial statements of the sample firms for three years before and after the IFRS adoption in Greece with some ratios. Also, a further analysis is applied in order to estimate the exact influence of IFRS adoption effects in a different time interval and is compared the year 2002 (the year that was firstly announced the IFRS adoption in E.U.) with the year 2005 (the first year of IFRS official adoption on firms’ financial statements). The received results reveiled that, concerning the IFRS adoption effects, compared the year 2002 with the year 2005, as none of the accounting ratios had a statistically significant change due to the IFRS adoption, there is no evidence for a specific impact of the adoption of IFRS on accounting-based information and performance from financial statements at the sample firms. In contrary, in examining the data for the sample firms over a threeyear-period before and after the IFRS adoption, the results revealed that two (EBIT margin; gearing) out of twenty accounting ratios had a statistically significant change and a positive impact due to the IFRS adoption.Τεκμήριο Inter-border Cooperation in the Area of Serres Prefecture and Consequences of the EU Bulgaria Accession – An Empirical Research(2013) Magoulios, George; Dimitriadis, Sotirios; Kydros, DimitriosThe enlargement of the European Union to twenty five (25) member states (2004) resulted in greater inequalities between European regions and subsequent expansions in other countries of south-east Europe may exacerbate these inequalities. These regional disparities in the enlarged EU must be reduced and dealt with an effective cohesion policy, part of which is the development of cross-border cooperation. According to the European Outline Convention of Madrid (1980), trans-frontier cooperation means any agreed transaction intended to encourage and cultivate the relationships between neighbouring local authorities of two or more parties. Euroregions promote cross-border cooperation between border regions and social partners in areas such as culture, education, tourism and the economy. From a purely economic standpoint, the preservation of natural or “invisible” borders is an obstacle to economic development. Since “invisible barriers” (languages, cultural problems, etc.) are hard to eliminate, the need to turn the boundaries in contact zones is stressed. These areas should be “bridges between states”, “channels for the mutual understanding of peoples”, “prosperity borders” and “cradles of development”. Factors that promote cross-border cooperation is, among others, the tradition and experience in collaboration, adequate common mechanisms by local authorities, the availability of sufficient financial resources, etc. On the contrary, factors that impede this cooperation are legal restrictions, disputes about the responsibility of the various levels of government, the limited experience of local authorities in the implementation of development programs, etc. It is estimated that, regarding the economic situation of regions bordering to candidate countries and the potential consequences of EU enlargement on them, the border areas of Greece and especially continental border areas, are among the least favoured regions, since they are faced with the most difficult situation regarding income, labour market dynamics, infrastructure and human resources. The prefecture of Serres, a border region, according to the predictions of General and Regional Framework for Physical Planning, is indented to become a regional growth pole of the trans- border cooperation. In this paper, based on the results of empirical research in institutions of Serres, we examine the collaboration of institutions of Serres with their respective Bulgarian ones. More particularly we explore areas of cooperation, opportunities and obstacles, results, and impacts on Serres by the accession of Bulgaria to the EU. The majority of institutions consider Bulgaria's endorsement to the EU as a positive progress for Serres and the extended region. Half or more of the institutions began their collaboration after the Bulgarian accession, aiming mainly to economic-development benefits and the exchange of experience and expertise, in fields of environment, culture, education, employment, entrepreneurship, etc.Τεκμήριο A Network Analysis of Greek Tech Blogs: A lonely road(2014-01) Kydros, Dimitrios; Vrana, Vasiliki; Theocharidis, Anastasios-IoannisTechnology ranks second among the top topics on blogging. However, little research effort has been devoted to investigating “tech” blogs while it is interesting to provide insights on their network, as they may have strong influence in the way that readers act and make decisions. In this vein, the paper records Greek “tech” blogs and their incoming links reported through their blogrolls. A directed network was created where blogs are noted as nodes and linked as directed arrows—arcs. The resulting network is analyzed using centrality and topological measurements and results are discussed in the social network analysis context. The network is a small world, with sparse density for a real-life social network and is low in-degree that shows off a kind of immaturity. Bloggers prefer to link to nodes with smaller degrees perhaps due to the fact that they are afraid of the growing competition thus they have reservations.Τεκμήριο Women entrepreneurship: problems and means of finance(2011) Magoulios, Giorgos; Kydros, DimitriosOne of the obstacles women entrepreneurs face is their access to financing. As in the rest of the developed world, in the EU and Greece special financial tools were created, aiming at specific groups, in our case, women. This paper attempts to review relevant literature, to highlight the need for incentives to SMEs and in particular to women entrepreneurs, to list the financial instruments in the EU and Greece, which generally relate to SMEs, especially in women who own or will create a business. The specific financial tools to strengthen women's entrepreneurship in Greece, despite the steps taken in recent years, are still limited. Those tools are more or less the same for women as for all entrepreneurs.
