The impact of proximity to urban areas on the success of fishing cooperatives: evidence from Mexico

[Under review]
(with E. Wintergalen)

Due to global trends in coastal development and population growth, a growing number of small-scale fishing (SSF) communities are within or near urban areas. Organization theory and local-level research suggest that these urban transformations may disincentivize certain forms of SSF self-organization while promoting others. These ideas have potentially important implications for SSF governance but have not been tested on a national scale. To fill this gap, this study uses data from Mexico to establish the relationship between fishing cooperatives’ travel time to the nearest urban center and the probability they are defunct. Results show substantial evidence of an association between a cooperative’s odds of survival and its distance from the nearest large population center. Specifically, a cooperative that is less than half an hour from a large urban center is about twice as likely to go defunct compared to a similar cooperative that is farther away. This result suggests that cooperatives in or near urban areas may face greater challenges compared to their more isolated counterparts. These challenges may include lower transaction costs of commercialization, ecosystem degradation, and the availability of alternative livelihood opportunities. Policymakers in Mexico and beyond should be aware of the possibility that urban fishers may be choosing alternative forms of self-organization, such as patron-client arrangements, that are less conducive to sustainable resource use and participatory governance. Additionally, conservation initiatives that rely upon long-term collaboration with fishing cooperatives may be likelier to succeed in locations farther away from cities, where cooperatives are less likely to go defunct.

What is the impact and value of hurricane forecasts? We study this question using newly-collected forecast data for the universe of land-falling US hurricanes between 2005–2022. We find higher wind speed forecasts increase pre-landfall protective spending. Erroneous under-forecasts of wind speed increase hurricane damage and after-hurricane rebuilding expenditures. Our main contribution is a new theoretically-grounded approach for estimating the marginal value of forecast improvements. We find that the average annual improvement reduced total per-hurricane costs, inclusive of unobserved protective spending, by over $500,000 per county. Improvements since 2007 reduced costs by 19%, averaging $2 billion per hurricane. This exceeds the annual budget for all federal weather forecasting.

The Economic Impact of Modern Piracy on Global Shipping

[Undergoing revisions]
(with G. McDermott, G. McDonald, J.C. Villaseñor-Derbez) Link

Maritime transport has been historically susceptible to piracy. While broad assessments suggest the impact of modern piracy causes large economic losses, the literature lacks quantification of the magnitude of the costs and the behavioral responses that underpin them. Here, we combine theory and a unique geospatial dataset combining more than 26 million shipping voyages and thousands of pirate encounters across the globe to test for behavioral responses and quantify their private and public costs. We find that shippers modify their path along a route to avoid locations with known pirate encounters, which increases voyage distance and duration leading to significant increases in fuel and labor costs estimated to be over US$1.5 billion/year. Additionally, emission of CO2, NOx, and SOx due to increased fuel consumption results in environmental damages valued at US$5.1 billion per year. Together, our results provide the first global estimates linking the presence of pirates to individual behavior and aggregate transportation cost, as well as its environmental impact, with major implications for the shipping industry and maritime security at a global scale.
