Adopting as analytical framework an organizational perspective we divide the main challenges that arise from the management of open innovation in two main categories: coordination problems as a result of open the innovation system to ideas and knowledge that may lie outside the boundaries of the firm and, incentive problems related with the creation and value capture of ideas an knowledge by the innovator. We describe and analyze several problems related with coordination and incentives.

The examined variables are market capitalization, industrial production, the economic sentiment indicator, and inflation, while the twelve countries are those which have adopted the euro. The empirical results reveal a strong effect of the first three factors, while inflation has a negative but not statistically significant coefficient. Further, the variables that affect the stock markets positively are market capitalization and the economic sentiment indicator. Finally, an applied statistical model confirms the significant convergence of the EU-12 stock markets in the long run, indicating a low geographic diversification across European markets.

In addition to ship loss, the international community has always been sensitive to the fact that such accidents may lead to serious environmental damage. Recently, after the Prestige accident (2002), maritime safety and effective protection of the marine environment, in cases where a ship finds itself in serious difficulty or in need of assistance, without presenting a risk to the safety of life of persons onboard, were placed high on the agenda. In response to the above, the international community (IMO) as well as the European Union, have undertaken to develop and implement a series of measures and policies aimed at increasing efficiency when facing incidents as well as serious accidents at sea. The recent debate initiated by the Green paper on EU Maritime Policy is indicative of the need to develop an overall maritime policy that will ensure a sustainable future for the industry. The framework described as “places of refuge” has already supported several countries to develop plans to accommodate ships in distress, in waters under their jurisdiction. Such plans have incorporated the necessary procedures to provide a ship in distress with a network of areas, where adequate means and facilities for assistance, repair, and salvage and pollution response exist, as well as criteria for selecting and designating such areas. This paper discusses issues that inevitably arise when a balance needs to be established between both the prerogative of a ship in need of assistance to seek a place of refuge and the prerogative of a coastal State to protect its coastline, in the context of enhancing maritime safety, as well as preventing and controlling marine pollution from the maritime industry.

An empirical investigation Authors: Katrakilidis, Constantinos P.; Trachanas, Emmanouil Abstract: This paper investigates the existence of possible causal linkages between the internal and external imbalances of the Greek economy, over the period 1960-2007, as well as the directions of the detected causal effects. Actually, it tests empirically the validity and rationale of the “twin deficits” hypothesis, taking into consideration the impact of the accession of Greece in the European Economic Community in 1981, which constitutes a great institutional change. By means of the ARDL cointegration methodology, errorcorrection modeling and Granger causality, we find evidence in favor of the “twin deficits hypothesis” for the Greek case over the pre-accession period (1960-1980), with causality running from the budget deficit to the trade deficit. However, over the post-accession period (1981-2007) the causal relationship is reversed, indicating changes in the linking mechanism of the two deficits and providing useful inferences for the national economic policy.
