We develop a composite indicator measuring the performance of national innovation systems. The indicator takes into account both "hard" factors that are quantifiable (such as R&D spending, number of patents) and "soft" factors like the assessment of preconditions for innovation by managers. We...

The growing literature on the potential role of energy resources around the Caspian Sea is dominated by geoplitics whereas economic aspects have been largely neglected thus far. The relevance of Caspian oil and gas reserves continues to be praised, though objective data on production and exports...

Shipbuilding has changed from a "heavy industry" to become a capital- and technologyintensive activity over the last decades. While Japanese, South Korean and Western European yards dominate the merchant shipbuilding market so far, Eastern European yards are increasingly active, in particular in...

Integrating large quantities of supply-driven renewable electricity generation remains a political and operational challenge. One of the main obstacles in Europe to installing at least 200 GWs of power from variable renewable sources is how to deal with the insufficient network capacity and the...

Coal continues to be an important fuel in many countries' energy mix and, despite the climate change concerns, it is likely to maintain this position for the next decades. In this paper a numerical model is developed to investigate the evolution of the international market for steam coal, the...

Structural changes in the European natural gas market such as liberalization, increasing demand, and growing import dependency have triggered new attempts to model this market accurately. This paper presents a model of the European natural gas supply, GASMOD, which is structured as a...

This paper presents results of simulating a more collusive behavior of a group of natural gas producing and exporting countries, sometimes called GASPEC. We use the World Gas Model, a dynamic, strategic representation of world gas production, trade, and consumption between 2005 and 2030. In...

The restructuring of telecommunication in Central and Eastern Europe occurs at a time when the classical structures of telecommunication are falling apart worldwide. Coming from the socialist system in which telecommunication did not exist as an independent economic activity, the Eastern...
