What would the economic impact be for Puerto Rico if the Jones Act were repealed or modified?

Executive summary
Repealing or modifying the Jones Act would almost certainly lower shipping costs to Puerto Rico and deliver measurable consumer and business relief, but the scale and distribution of those gains—and the fiscal, security, and industrial trade-offs—depend on how reform is designed and implemented [1] [2]. Existing studies and policy organizations portray a clear net cost to the island today, while industry and national-security voices warn of job losses and weakened domestic maritime capacity, making any change a political and economic balancing act [1] [3] [4].
1. Direct transport-cost impact: what the evidence says
Multiple independent papers and policy reports find that the Jones Act raises the cost of maritime transport to Puerto Rico by a substantial margin; a recent working paper estimates an annual welfare burden of roughly $1.4 billion on Puerto Rico, driven largely by higher consumer prices and inefficient cargo routing under cabotage rules [1]. Academic and think‑tank analyses also note that container shipments to San Juan have historically cost far more than comparable Caribbean routes—one Federal Reserve Bank of New York finding cited at a Stockton panel suggested east‑coast-to‑San Juan container rates could be roughly twice those to Jamaica or the Dominican Republic—which implies sizable savings if competition were allowed [5].
2. How lower shipping costs would flow to consumers and firms
Lower freight rates, in theory, translate into cheaper food, fuel, and intermediate inputs; advocates estimate savings that range from hundreds of millions to over a billion dollars per year in aggregate consumer welfare [6] [1]. Reports from legal and civic organizations argue that because Puerto Rico imports the vast majority of its food and many manufactured inputs, reduced maritime costs would be especially meaningful for low‑income households and for firms whose margins are squeezed by freight‑inflated input prices [7] [6]. Precise pass‑through rates, however, vary by sector and are sensitive to market structure—an evidentiary gap in public studies that makes exact household-level impacts hard to state with certainty [7].
3. Industrial structure, competitiveness, and long‑run growth
Scholars and local commentators contend the Jones Act distorts Puerto Rico’s industrial mix by biasing toward air‑shipped inputs and away from maritime‑intensive manufacturing, with one analysis claiming a 77% shortfall in sea‑shipped production inputs relative to air imports versus comparable Caribbean peers—a dynamic that suppresses export competitiveness and manufacturing investment [8]. If reform reduced maritime costs, Puerto Rico could regain competitive advantages for certain export‑oriented or scale‑sensitive industries and more easily deploy large capital projects—particularly in energy infrastructure tied to renewable goals—but quantifying new investment and jobs requires modeling beyond current public studies [8] [9].
4. Disaster relief, resilience, and infrastructure implications
Reform advocates point to emergency and resilience benefits: waivers have been used to speed fuel into Puerto Rico during crises, and critics say the Jones Act complicated relief after Hurricane Maria [4] [10]. Conversely, supporters argue that a robust domestic fleet provides predictable capacity and security in wartime or geopolitical stress, so any permanent change should incorporate contingency arrangements for national defense and emergency logistics [4] [5].
5. Counterarguments and winners/losers from repeal or amendment
Maritime unions, certain shipyards, and national‑security proponents emphasize that the law supports U.S. shipbuilding, crewing, and strategic sealift jobs; industry studies commissioned by unions assert that Jones Act services provide stability and local economic contributions to Puerto Rico itself [3]. Reform could therefore cost U.S. maritime employment and undercut the domestic industrial base unless accompanied by targeted support—an implicit agenda stressed by pro‑Jones Act sources that contrasts with reformers focused on consumer prices and territorial equity [3] [4].
6. Practical scenarios and political economy: repeal vs. targeted modification
Full repeal would most rapidly open competition and likely deliver the biggest immediate freight savings, but it would provoke stronger industry resistance and pose transitional risks to U.S. shipbuilding capacity; many commentators instead advocate targeted exemptions or time‑limited waivers for Puerto Rico, which could capture much of the island’s near‑term benefit while leaving national‑security safeguards intact [8] [5]. Congressional proposals and state resolutions in 2025 reflect growing bipartisan interest in reform or relief, but the final economic outcome will hinge on exemption design, regulatory detail, and whether savings are passed on to consumers and businesses [8] [9].
Conclusion and limits of the record
Available studies converge that the Jones Act imposes a meaningful annual burden on Puerto Rico and that reform could lower prices and improve competitiveness, but precise job, investment, and fiscal impacts depend on assumptions about pass‑through, industry responses, and transitional policy—areas where public evidence remains incomplete and contested among advocates, scholars, unions, and government analysts [1] [3] [7].
