New Analysis Helps Manage Risks to Shipping in the Great Lakes

Modeling of mysteriously fluctuating water levels in the Great Lakes has helped to optimize the prices of shipping insurance contracts along with investments in dredging navigation channels.

A new step has been taken in bringing financial dimensions into water resources decision making. In Meyer et al. [2020], authors from the Universities of North Carolina and Massachusetts have examined both financial and engineering responses to the risk of water level fluctuations for navigation in the Great Lakes. They show that two very different adaptation strategies—dredging waterways and insurance contracts—can be combined practically and analytically. This is a fascinating example, not least because fluctuations of water levels in the Great Lakes are still not entirely predictable, so the risks of low water levels in navigation channels need to be effectively hedged. The finance sector should be paying attention!
