Public goods and the public financing of major European seaports

Seaports are recognized for their importance in facilitating trade growth and associated economic development. These attributes often give rise to the notion that seaports, or infrastructure elements of seaports, are public goods. Public goods are regarded as goods or services which a market acting in isolation might have difficulty in providing, or at least providing in sufficient quantity and/or at a competitive price. An important element of a public good relates to its non-rival consumption, the implication being that it is impossible to exclude anyone, whether they pay or not. Key questions this paper seeks to address are, what constitutes public goods in seaports, to what extent is it necessary for the public sector to provide these goods, and can such intervention lead to market distortion in respect of competing ports? The paper describes the more common examples of public goods in seaports. This is followed by discussion of public and private sector investment at major north European seaports. The paper considers the potential for market distortion due to public sector expenditure on so-called public goods in seaports, and proposes that a more cohesive policy for major ports, particularly those very large containerports serving a common European hinterland, is necessary in order to deliver a sustainable transport system in the long term.
