Why Natural Disasters are a Disaster in Common Property Resources

Developing countries tend to suffer the most from natural disasters, but the mechanisms underlying this outcome are poorly understood. I postulate that the lack of strong and well defined property rights for renewable resources is a key factor increasing the impacts of disasters. Using a theoretical model for renewable resource extraction with irreversible investment, I show that common property regimes incentivize agents to invest in ways that exacerbate both immediate losses from disasters and increase the cost of recovery after they hit. I test these predictions by examining investment patterns across institutional regimes in Chilean small scale fisheries before and after a tsunami in 2010. The results indicate causal links between more common regimes and excessive investment increasing the cost of the tsunami. This paper contributes to the ongoing work on the economic impact of natural disasters and provides an argument for how institutional regimes can be used as mitigation strategies. Link

Transboundary Marine Protected Areas

(with Costello, C.)

Countries exploiting transboundary fisheries face strong incentives for over-exploitation. This basic economic insight has been validated empirically; transboundary fisheries tend to be in worse condition than fisheries in single nations. Thus, transboundary fisheries pose a significant, and globally ubiquitous, management challenge. Attempts to solve this challenge through cross-country cooperation have been largely unsuccessful because defection is often more attractive than adhering to cooperative agreements. We explore the economics of an alternative solution, a transboundary marine protected area (TMPA), and derive the conditions under which it can improve profits and stock biomass, even in the presence of individually-rational non-cooperation across countries. We find that well-designed TMPAs have the potential to overcome non-cooperation across countries; this result is strengthened when stocks have relatively low growth rates. A well-designed TMPA can earn higher profits for both countries, increase stocks in both countries, and reproduce the fully cooperative outcome. Link

The Economic Impact of Modern Piracy on Global Shipping

(with G. McDonald)

Poorly defined and enforced maritime jurisdictions have historically rendered the shipping industry vulnerable to piracy. Currently more than six hundred attacks take place every year, with most of them taking place in the Straits of Malacca, West Africa, the waters off Somalia, and the Indian Ocean. In this paper, we develop the theoretical background and empirically establish and quantify the causal effect of piracy on the shipping industry. We update past theoretical efforts by including strategic behavior across and between shippers and pirates, and compile a unique global geospatial dataset to test those insights. The empirical analysis utilizes high spatial and temporal resolution information on pirate attacks from the US National Geospatial-Intelligence Agency, individual vessel tracks of all known cargo and tanker vessels that use the AIS vessel monitoring system, and individual track weather patterns. Our results show that pirate attacks lead to significant aversion responses by the shipping industry that translate into an industry-wide waste of fuel and labor resources that far exceed the cost of anti-piracy deployments. This paper contributes to the public debate on maritime jurisdiction enforcement and international duties for the protection of trade channels, and their role in global non-renewable resource utilization.
