Implication

Randomized trial estimates operational disruptions from weather in port logistics, highlighting economic implications.

Key Points

This research aims to estimate the operational effects and opportunity costs associated with weather-induced stoppages at the Rio Grande Port Complex.
Combined operation-level port microdata from ANTAQ and meteorological data from INMET.
Utilized a two-step design based on Entropy Balancing and Weighted Least Squares with HC3 robust standard errors.
Analyzed waiting-to-berth time, operation time, and total port stay over the period 2020–2024.
Cumulative opportunity costs are estimated at US$ 5.39 million for General Cargo and US$ 7.60 million for Solid Bulk.
Statistically significant increases in waiting-to-berth time, operation time, and total port stay after climate-related stoppages were observed.
Evidence shows persistent losses in effective port capacity associated with adverse weather conditions.
