- Transportation is the lynchpin. Electric power generation and transmission, freight rail, warehousing and logistics, pipelines and energy terminals are mostly in private ownership and doing just fine. Social infrastructure (schools, hospitals, correctional facilities, the courts) creates broad public benefits and is largely publicly financed, albeit with private competition in some areas. Same with water and sewage. So those are mainly off the table. Fixing our roads, bridges, tunnels and transportation hubs are a must and will have the biggest impact. Government tends to be pretty bad at multitasking, so Trump should narrow the immediate focus on the transport sector.
- Public or private, or both? Done right, government involvement in infrastructure is inevitable. It is the key to the effective use of private capital in transportation. It provides operating concessions, eminent domain, rate-setting, engineering and safety standards, and in some cases financial partnerships with the private sector (public-private partnerships). There always has to be a coincidence of interest between the private and government sectors that is carefully anchored in durable and robust project agreements, and everyone has to be able to claim victory.
The key issue is to identify projects that generate robust future cash flows that can be turned into today’s private sector financing – attractive non-listed and listed equity investments, bank lending facilities capable of coping with construction risks supported by solid infrastructure bankers who have been around the block a couple of times, and the kinds of high-quality long-duration debt instruments backed by realized cash flows that big institutional investors like insurers and pension funds crave. Attractive projects that cannot be calibrated to meet these conditions, however valuable, will have to remain off the table for the private sector.
- OK on the private sector involvement, but what’s with the tax credit idea? It’s not obvious how private infrastructure financing can benefit from tax credits. Municipal bonds are already tax-favored - a status that may be up for negotiation as part of Trump’s tax reforms. Any additional infrastructure-specific tax benefits would probably take the form of corporate “tax subsidies” on “approved” projects, which puts the government in a position of deciding which worthy projects would count toward the promised $1 trillion in federal support. Here the U.S. can learn quickly from Europe and Asia, where good outcomes in many cases seem to have captured broad public support for public-private ventures and where creative moves, such as the European Bank for Reconstruction and Development (EBRD) by now have a track record that can teach us some valuable lessons on what works.
- Be patient about jobs. Infrastructure investments increase aggregate spending in the economy but at the same time require high-quality, specialized labor that’s in limited supply due to U.S. education and training bottlenecks. This could put the brakes on promised employment gains. The newly popular emphasis on vocational training for high-skill jobs and attractive pay that comes with it should help. A key issue is the excruciating delays that often beset US infrastructure projects in our hyper-litigious and politically testy environment. Trump has already tried to clear away some of the regulatory underbrush and should make sure it actually happens. Still, benefits that start flowing a decade or more from now aren’t worth very much today, and in any case will be harvested by governments - so they require a good dose of statesmanship.
The devil is in the details. But the product of a good infrastructure plan is significantly higher income and output in the short term and economic growth in the long term, so that prospects are seen to improve for everyone. The product of good tax reform is much the same. The two issues are joined at the hip. Both are positive-sum games, with plenty of scope for promising gains in one domain to compromise perceived losses in the other. In politics, more degrees of freedom are good for outcomes that are in the public interest. Linking infrastructure to tax reform can make a positive contribution, so Trump should give it a shot.
