Dr. Vasileios Kosmas

Postdoctoral Research Fellow
Maritime Logistics

Vasileios Kosmas is a postdoctoral research fellow in the field of Maritime Logistics at the Kühne Logistics University since January 2020. His PhD program under the supervision of Professor Dr. Michele Acciaro specializes in sustainable shipping and runs in cooperation with the Copenhagen Business School.

Vasileios received his MSc degree in Marine Transport with Management from Newcastle University in 2014. His gain in expert theoretical knowledge and the improvement of his research skills contributed to his achievement of being awarded his MSc with distinction (i.e. First Class Honours). In addition, Vasileios received a distinction grade for his final thesis with the title “Inland waterway shipping of containers in Germany”. The thesis presented the up-to-date role of this mode of container transport in Germany’s logistics system (environmental friendliness, economic considerations, social aspects etc.) and identified also if there are any potentials for its further market expansion.

Vasileios holds also a BSc degree in Economics, with focus on Planning and Development, from Aristotle University of Thessaloniki (AUTH). Moreover, he gained valuable professional experience as an economic consultant and analyst during his internship in the Development Company of the Professional Chamber of Thessaloniki.

Abstract: A fuel levy is one of the market-based measures (MBMs) currently under consideration at the International Maritime Organization. MBMs have been proposed to improve the energy efficiency of the shipping sector and reduce its emissions. This paper analyses the economic and environmental implications of two types of levy on shipping bunker fuels by means of an analytical model built on the cobweb theorem. A unit-tax per ton of fuel and an ad-valorem tax, enforced as a percentage of fuel prices, are examined. In both cases, a speed and fuel-consumption reduction equivalent to an improvement in the energy efficiency of the sector would be expected as a result of the regulation enforcement. The speed reduction in the unit-tax case depends on fuel prices and the tax amount, whereas in the ad-valorem case it relies upon the enforced tax percentage. Both schemes lead to industry profit decline, the extent of which depend on the structure of the levy and market conditions. Since there is concern that the costs resulting from the policy will be passed from shipping companies to their customers along the supply chain, the paper dwells on how the costs arising from the enforcement of the levy will be actually allocated between ship-owners and operators, and cargo-owners. In a market characterised by high freight rates and with no or limited excess capacity, a higher percentage of the total tax amount is transferred from ship-owners to shippers. In case of a recession the opposite happens.
