“Relative Labor Demand in an Open Economy”.


03/2003  – 55th International Atlantic Economic Conference – Vienna.

Abstract: This paper contributes to the discussion concerning the nature of the well-documented worsening of wage and employment inequality in western economies during the past three decades. It critically discusses the use of the traditional Heckscher and Ohlin approach to analyze the distributional effects of international competition. The paper also discusses an innovative theoretical scenario in order to effectively explain the empirical observations. The model overcomes the problem of a dichotomized labor market, which is an unfavorable result of the traditional approach. Furthermore, the factor-biased character of the technological change becomes endogenous as the strength of foreign competition and the induced incentives for technical innovations are taken into consideration.

“Soft and Hard Within- and Between-Industry Changes of US Skill Intensity: Shedding light on worker’s inequality”

“Soft and Hard Within- and Between-Industry Changes of US Skill Intensity: Shedding light on worker’s inequality” (Co-author: Lynn Riggs)

Abstract: In order to examine the worsening of inequality between workers of different skill levels over the past three decades and to further motivate the theoretical discussion on this issue, we use the decomposition methodology to focus on the interaction of within- and between-industry changes of the relative skill intensity in U.S. manufacturing. Unlike previous work, we use more detailed levels of industry classification (5-digit SIC product codes), and we analyze the impact of plants switching industries as well as of plant births and deaths on these changes. Internal, plant-level data from the U.S. Census Bureau’s Longitudinal Research Database and the new Longitudinal Business Database provide us with the requisite information to conduct these studies. Finally, our empirical conclusions are discussed in relation to the inspired theoretical inference, as they enrich the debate concerning the sources of the inequality by justifying the skill-biased character of technical change.

“Transportation Costs and Final Prices: A case study for fuels in Greece”

“Transportation Costs and Final Prices: A case study for fuels in Greece” (Co-author: Aristea Gkagka). SOUTH-EASTERN EUROPE JOURNAL OF ECONOMICS,6(2), Fall 2008

Abstract: In the present study, we focus on the regional differentiation of final fuel prices in major cities of Greece. While recognizing the significance of transportation costs, we observe the implications of other socioeconomic and geopolitical factors. This allows us to consider the inefficiencies of the Greek fuel market and to discuss relevant policy considerations.

Abstract: Standard growth theory emphasizes the closure of gaps: as internationalization proceeds, socioeconomic, structural characteristics of different countries become similar. Despite the fact that the European Union (EU) represents a historical experiment of a region of gradually strengthening internationalization, a wide range of EU studies reject the convergence hypothesis, showing an unclear development of standard deviation in time. Many of the studies find that something went wrong in the 1980s, yet they describe it as the result of a temporary effect. In the present paper, we show that the puzzle of the 1980s is not a short-term break in a continuous trend, but a complete alteration of the process, a structural shift toward a persisting period of continuous divergence! The previous trend of closing the gap among the member countries was reversed completely: in 2010, the coefficient of variation returned to higher levels than those of 1960. Second, all previous gains of labor vanished: in the period 1980-2005, real wages lost about 35 percent against per capita gross domestic product (GDP). The empirical findings we provide support our main suspicion: apart from confirming the Organization for Economic Cooperation and Development (OECD) observation of growing and persisting inequality in all Western economies, the gradual transition of the European free trade area into an economic and monetary union, accompanied by the prevalence of a specific policy, explains the prevalence of a period of deepening divergence since the beginning of the 1980s.

“Growth and EU-Trade Relations: A Case Study”

“Growth and EU-Trade Relations: A Case Study” (Co-author: Aristea Gkagka).


05/2009 – XIX International Conference of IT&FA – Beijing

09/2010 – European Trade Study Group 2010 – Lausanne

Our analysis differs in two ways from the existing trade / growth literature. First, we testify the validity of the four thinkable relevant hypotheses for the same dataset simultaneously: export-led growth, import-led growth, growth-led imports and growth-led exports. Second, we check for the different effects that might result from trading within a regional trade agreement regime. We see that trading partners do matter: EU-15 growth seems to be favored by intra-EU ex-ports and imports from the rest of the world, with the exception of China. Yet, the reversed hypotheses are not confirmable. Therefore, even if trading with specific countries creates positive growth effects, they are not likely to be long-lasting.

“Green Way-out from the crisis: the European experience”

“Green Way-out from the crisis: the European experience” (Co-author: Eva Sdrolia).


05/2012 – 8th International Conference of ASECU, University of Rzeszow, Poland

Global economic crisis, along with domestic structural inefficiencies, weakens growth perspectives for the less developed and/or the financially weaker economies of Europe. On the other hand, the relevant literature that technological innovations, especially with respect to the ecological aspects of products and processes, could be an effective way-out. The present paper contributes to this discussion in two ways: first, we discuss relevant case studies of certain mulitnationals. Second, we proceed with a panel data analysis of recent intra-EU data, estimating the effect of enviromental expenditures and investments on exporting activity, considering also “gravity” – explanatory variables. We conclude that “green” – investments seem to have a positive effect, both, in the micro – as well as macro – dimension, while expenditures could affect extroversion and competitiveness adversely.

“What lies Behind “Inflation-Phobia” and European “Corset Policy”?”

“What lies Behind “Inflation-Phobia” and European “Corset Policy”?”

JOURNAL OF STOCK & FOREX TRADE 1:e106. doi:10.4172/jsft.1000e106

The present situation in the European Union (EU) provides an advantageous field for cutting edge research, basically due to the following reasons: first, given the systemic global crisis and the appearing structural weaknesses of European integration, policy meets (again) economics, in terms of the problematic that dominates the public debate, but also of the recognized necessity for going into the essential “second step” of political integration, next to the creation of €-zone. Second, the European area offers a historical experiment for the prospects and the wider effects of regional trade agreements and custom unions, as well as the expectations with respect to the process of economic internationalization. Hence, I strongly believe that scholars should invest effort and time in a thorough analysis of the recent developments in the EU, which, by the way, relates strongly to the very purpose of the Journal of Stock & Forex Trading. This leads to the main aspiration of the present editorial: to summarize personal views that may provide motivation for relevant contributions…

“Black Sea: Old Trade Routes and Current Perspectives of Socioeconomic Co-operation”

“Black Sea: Old Trade Routes and Current Perspectives of Socioeconomic Co-operation”, (Co-author: Domna Lyratzopoulou). PROCEDIA ECONOMICS AND FINANCE by Elsevier, Volume 9, 2014, Pages 74–82

05/2013 – 5th International Conference EBEEC2013, Istanbul.

Abstract On the coasts of the Black Sea, across the coastline of six countries (today), 32 important medieval and byzantine port-cities have flourished the last decades. Those port-cities facilitated the merchandise shipping from Europe to Central Asia and faraway China, through sea roads and routes followed not only by merchandisers and travelers but also by emperors and pilgrims. This paper constitutes a summarized literature review of the economic history of some of the most important Black Sea port-cities, counting from the 19th century, through 20th century and up to the present. It also seeks to examine the reconstruction and development of those port-cities after the demise of the Ottoman Empire, a number of Wars, political changes and finally through the economic and political transition of the Black Sea area. Additionally, the paper reviews the Black Sea trade routes followed by the merchants of the examined period. We conclude on current comparative advantages of the wider region and the perspectives for socio-economic development.
