Podcast on Maritime Policy

I recently recorded an episode of The Economics Detective podcast with Garrett Petersen. The subject of the podcast is my paper, “U.S. Maritime Policy and Economic Efficiency.” A link to the paper is here. A link to a blog post I recently wrote about the paper is here.

On Maritime Policy

Some time ago, I was listening to NPR and the hosts were discussing the Jones Act. For those who are unaware, the Jones Act requires that any shipping done from one U.S. port to another U.S. port must be carried by a U.S.-flagged ship with a U.S. crew that was built in the U.S. The hosts claimed that they could not find an economist who could explain why this sort of law existed. The policy seemed like a run-of-the-mill protectionist giveaway. My reaction was much different.

Here we have this law that is nearly 100 years old and no economist can explain why it exists? The only plausible explanation is that this 100-year-old law is a protectionist giveaway? This seems unlikely. One would have to believe that democracy is incredibly inefficient. This is especially true when one hears the estimates of the costs of the Jones Act. Why are voters in the U.S. just leaving billions of dollars on the sidewalk?

There is an entire literature on elections and accountability that seems to suggest that elections discipline the behavior of politicians to follow the will of the voters. However, as part of this literature, this can lead politicians to give greater weight to special interest groups. These groups tend to have more information than the average voter and provide more feedback to politicians. As a result, politicians might be too responsive to special interest groups in trying to achieve re-election. Of course, what seems like an obvious question (to me) is how special interests could convince politicians to support this legislation for so long without some other special interest group emerging to get the inefficient policy repealed. In fact, I have made the argument (along with my co-authors, Brian Albrecht and Alex Salter) that, in a world with endogenous entry of special interest groups, long-lasting policies must either have modest costs or actually efficient.

Given my prior beliefs on the endogenous entry of special interest groups, I figured that something like the Jones Act must either be substantially less costly than conventionally claimed. I decided to study this more closely and what I discovered is that there is a clear and consistent pattern of subsidizing the shipping industry throughout U.S. history. In addition, there is also an argument that such subsidies are actually efficient. So, I decided to write a paper about it. For those who don’t want to read the whole paper, what follows is a synopsis of my argument.

Consider the following basic idea. During times of peace, a navy needs less capacity than during times of war. At the same time, a navy needs to have the ability to expand rapidly when war occurs. Excess capacity during times of peace could be wasteful. A potential solution to this problem is for the navy to use private ships to assist them during times of war. Of course, there are several problems with doing so. First, diverting private ships for naval use might impair international trade. Second, foreign crews might not want to have any part in another country’s conflict. Third, if the government offers to pay ships for their services once conflict has begun or is imminent, it might be subject to a hold-up problem. Fourth, if the government simply expropriates the ships for naval use, the expectation of expropriation will cause the shipping industry to underinvest.

Given the need for a naval auxiliary, it would seem like some sort of Coaseian bargain is in order. One possibility is for the government to provide peacetime subsidies to the shipping industry in exchange for this industry’s services during times of war. This sort of thing is not without precedent.

What we have here is a possible argument for why the U.S. government offers maritime subsidies. But how would we know if this is actually the case? How do we know that I haven’t crafted a just-so argument to put a thumb in the nose of those who say there’s no justification for policies like the Jones Act? Well, I would suggest that we would observe multiple things. First, we should observe a clear and consistent pattern of maritime subsidies across U.S. history. Second, we should observe similar subsidies for other transportation services.

It turns out that both observations are true. As I detail in my paper, there is a clear and consistent pattern of subsidizing shipping and revising and updating these maritime subsidies in the run-up to military conflict or in the aftermath of conflict. Furthermore, the legislation for these subsidies, as well as speeches by FDR and Richard Nixon, explicitly outline the importance of these subsidies for the role of the merchant marine as a naval auxiliary.

There is also a history of doing this with other forms of transportation. In the decade prior to World War I, the U.S. became concerned about the number horses that would be available during times of war. Again, the U.S. could potentially purchase horses from private citizens in the event of war. However, military horses do not always have the same characteristics as the horses used on farms. Furthermore, mother nature determines the “time-to-build” for horses such that no reallocation of resources or productivity improvements allow military-ready horses to be produced any faster. As a result, the U.S. government set up remount depots and subsidized horse breeding.

Similarly, during both World War II and the Korean War, the U.S. government requisitioned private planes to provide airlift during the war. The role of aircrafts was later formalized with the creation of the Civil Reserve Air Fleet in 1952. This program allows the government to use participating member planes for airlift during times of war. In exchange, the government uses the participating airlines for airlift during times of peace and the amount of business and compensation provided is a function of the complementarity of the planes for military airlift.

In other words, what we see is a clear and consistent pattern of Coaseian bargains across time and different methods of transport as it relates to creating additional transportation capacity during times of war.

This finally brings me back to the Jones Act. As I detail in my paper, the Jones Act is part of a larger subsidization effort on the part of the U.S. government since its founding. In fact, the cabotage restrictions that are so notoriously criticized actually originated in 1817.

As I stated at the beginning of this post, much of the criticism of the Jones Act is based on its perceived astronomical costs. If one takes these costs as given, then when can understand why it is so hard to find an economist who can explain why it exists. However, what I have found is that these costs are dramatically overblown because they fail to consider the proper counterfactual. When estimating the costs of the Jones Act, most critics compare the cost of U.S.-flagged ships engaged in U.S.-based trade to the costs of foreign-flagged ships engaged in international trade. When you do so, what you find is that the cost of U.S. ships is almost 3 times as high as the foreign-flagged ships. This makes the Jones Act seem really expensive! Shouldn’t we just let the foreign-flagged ships do the work?

What this comparison ignores is that these foreign-flagged ships often fly so-called flags of convenience. These flags allow them to avoid the sort of taxes and regulations that they would face by flying the flag of a major developed country. Port-to-port U.S. shipping is considered domestic production. As a result, any ship engaged in U.S. port-to-port shipping would be subject to U.S. tax law, immigration law, labor law, and environmental laws. Perhaps most important among these compliance issues is immigration law. Under current U.S. law, foreign crews could not work on a ship conducting U.S. port-to-port shipping. This means that the labor costs of the crews on foreign-flagged ships would be substantially higher. In fact, back-of-the-envelope calculations suggest that once labor costs are taken into account, the cost of U.S. ships would only be 8% higher than foreign-flagged ships rather than nearly 3 times higher – and this is without taking into account taxes and other regulatory costs.

So, perhaps the reason that voters in the U.S. aren’t reaching down to grab billions of dollar bills on the sidewalk is that they recognize these dollars as a mirage.

None of this is to say that current maritime policy is optimal. In fact, I detail criticisms of current policy in my paper and offer suggestions for reform. Nonetheless, my paper illustrates that there is a compelling reason that countries offer maritime subsidies. This significantly changes the relevant counterfactual. So there is at least one economist who can now explain the existence of the Jones Act to the good people at NPR.

Macro Musings

This week I was a guest on David Beckworth’s Macro Musings podcast. We discussed my policy brief on the labor standard as well as monetary policy more generally. Here is a link for those interested.


A couple of updates:

  • The topic of this month’s Cato Unbound is J.P. Koning’s proposal for the U.S. to issue a large denomination “supernote” and to tax that note as a way of punishing illegal activity. I will be contributing to the discussion this month along with James McAndrews and Will Luther. You can read J.P.’s lead essay here. The response essays will be linked below the lead essay. My response essay will appear next week.
  • My paper with Alex Salter and Brian Albrecht entitled “Preventing Plunder: Military Technology, Capital Accumulation, and Economic Growth” has been accepted at the Journal of Macroeconomics. I think that this paper is based on a really interesting idea (biased, I know). The basic idea is that military technology is a limiting factor for economic growth. We also suggest that both economic growth (at least to some degree) and state capacity could be driven by this common factor.

Monetary Policy as a Jobs Guarantee

Today, the Mercatus Center published my policy brief on the idea of a “labor standard” for monetary policy that was first proposed by Earl Thompson and David Glasner.

Towards an Alchian-type Approach to Political Economy

In my previous post, I discussed what I called the sleight of hand of an Olson-approach to political economy. The basic idea of that post was that Olson’s theory of concentrated benefits and dispersed costs is often used to malign policies deemed to be inefficient. The sleight of hand aspect is as follows. First, the economist deems a particular policy to be inefficient using a standard theoretical model. Second, the economist hypothesizes that the reason we have such an inefficient policy is due to special interests getting what they want because the costs are dispersed. Third, the economist examines either in historical detail or through regression analysis the role of special interests in getting the policy implemented. Fourth, if special interests are found to have had an effect on the policy being put into place, the economist concludes that the reason we have this inefficient policy is due to special interests. However, the inefficiency of a particular policy is determined by some theoretical model. The empirical finding that special interests had a marginal effect on the policy’s implementation is then used to explain why we got this inefficient policy. Whether or not this is the correct interpretation of the empirical result depends critically on whether the theoretical assertion is true!

Let me elaborate on this point using an example. Consider the example of pollution, which is a principles of microeconomics textbook version of an externality. Suppose that in the absence of special interests, such as environmental groups, pollution would go untaxed. Empirical evidence would show that a tax on pollution was due to the influence of special interest groups (the environmental groups). If we had no concept of externalities and we used the perfectly competitive model as our benchmark model, the conclusion would be that special interests were to blame for this inefficient policy. However, since this is a commonly understood externality, one would not conclude that special interests were to blame for an inefficient policy. On the contrary, the special interest groups would be the reason for implementing the socially optimal policy. In other words, finding evidence of the role of special interest groups does not tell us anything about what is efficient or what is optimal. To do so, we need an explicit theoretical argument or model. Not only that, to come to the correct conclusion we need a correct theoretical model in the sense that it addresses relevant factors, such as externalities.

In my previous post, I criticized economists for too often simply asserting that a policy is inefficient and subsequently applying Olson’s model to explain why we get such stupid, inefficient policies. I also argued that political economy should shift to using an evolutionary argument. In that post, I was short on some of these details. As a result, in this post I want to outline what I meant by this.

In 1950, Armen Alchian published a paper entiled “Uncertainty, Evolution, and Economic Theory.” In that paper he outlines an evolutionary approach to economic theory. Specifically, he argues that it might be misleading to describe firms as profit-maximizers. The reason is that when firms face decisions, there might be a distribution of outcomes across each decision. If these distributions overlap, then it doesn’t make sense to think of the firm as maximizing anything. For example, one distribution might have a higher average profit, but also be associated with a greater variance in profit than some other possible decision. So if firms aren’t maximizing profit, what are they doing?

Alchian suggested that we think of firms as practicing trial-and-error and imitation. Firms try certain things to see what works and imitate things that worked for other firms. Along the way, some firms benefit from good luck and other firms suffer from bad luck. Nonetheless, through this process of trial-and-error, imitation, and uncertainty, the profit mechanism ultimately determines what firms are able to stay in the market and what firms must leave the market. Firms that earn a profit are able to continue operating. Firms that are losing money will be forced to drop out of the market. The profit and loss mechanism therefore selects for firms who are making a profit. This might be due to the firm’s decision-making or it might be due to luck (or some combination of the two). Nonetheless, the economist should be able to explain the success (or lack thereof) of firms. An economist can look at the characteristics and decisions shared by the surviving firms and contrast those characteristics and decisions of the firms that have left the market. In doing so, one can get the sense of the role of decision-making and luck as well as the types of decisions that have proven successful and unsuccessful.

In my view, political economy would benefit from the same sort of approach. Rather than start with a baseline model to determine whether some policy is efficient or not, one should start with the policy itself.

1. What was the primary justification for the policy? More importantly, under what grounds could we consider the policy to be efficient? These questions help to set a much more relevant benchmark than some abstract model of the economist’s choosing.

2. Once these questions have been answered, the economist has some general idea about the conditions under which the policy would be considered efficient. Now, one can take an evolutionary approach to the policy. Did the policy survive for a long time and/or is it still around? What other states or countries have adopted the same or similar policies? How did states and/or countries adopting the policy perform along the relevant dimension in comparison to others? Did any other states/countries have similar policies and abandon them? What happened if they did?

The answers to these questions help to determine the conditions under which the policy survived and the relative success of those places that implemented the policy. This can help to determine if the policy actually achieved what it was supposed to and/or whether the policy is consistent with conditions under which it could be considered efficient. In addition, if the policy seems to have been an efficient response to a particular problem, it is then possible to examine why some places got rid of it and had to bear the cost of doing so thereafter.

In short, I think that it would be useful to do something in political economy with respect to government policy today that Pete Leeson has done with policies and institutions of an earlier time and place. Leeson’s work often starts by examining some policy, law, or institution that seems completely weird, strange, or backwards. He then starts with the premise that it must have been efficient. He outlines the conditions under which the policy or institution would have been efficient and then tests that theory by examining what would have to be true for his efficiency hypothesis to be correct. This approach to political economy or public choice is clearly enlightening, judging by Leeson’s publication record. However, I notice a reticence on the part of many political economists and public choice economists to take the same approach to more recent policies and institutions. The attitude toward more modern policies and institutions seems to be that we “know” that policy X or institution Y is inefficient because economic theory tells us so. Therefore we need to explain why it exists. But how do we “know” this any more than we “know” that trial by battle was a backwards and barbaric practice of no practical use? Leeson’s work showing that trial by battle was a good way of eliciting the true value that particular claimants placed on land was actually quite efficient. So maybe we should be a bit more humble about modern policy as well.
