Competition and Coordination in Infrastructure: Port Authorities' Response to the Panama Canal Expansion (JMP)
Who should build infrastructure and how much should they build? In the United States, transportation infrastructure decisions are mostly made at the state or local level. I study seaports during a period when massive investments were being made on the East Coast to prepare for the larger vessels that could navigate an expanded Panama Canal. Competition between the ports spurs more investment and lower prices, but if ports do not internalize their business-stealing effect on others, there may also be overinvestment--especially with subsidization. With data on all container imports and capital costs of the major US ports, I estimate a model of the investment game that port authorities play with one another. I find the spatial distribution of investment on the East Coast would be very different if ports coordinated their activity.
