How Costly is Modern Maritime Piracy?

This paper focuses on the impact of maritime piracy on international trade. Piracy increases the cost of international maritime transport through an increase in insecurity regarding goods deliveries. Bilateral trade flows between the main European and Asian countries over the 1999 to 2008 period are used to estimate an augmented gravity model that includes various measures of piracy acts. We found robust evidence indicating that maritime piracy reduces the volume of trade; the effect of 10 additional vessels hijacked being associated to an 11% decrease in exports. Consequently, the current cost of piracy in terms of international trade destruction is estimated at 24.5 billion dollars.

That is from a paper by Bensassi & Martínez-Zarzoso (Review of International Economics, November 2012). An ungated version is here.
