Using Markets to Fix Markets

Robert Stavins on the "enlightened use of markets" to make fisheries sustainable:

Using Markets to Make Fisheries Sustainable, Robert Stavins: Around the world, over-fishing is leading to severe depletion of valuable fisheries. ... According to the United Nations Environment Program, fully 25 percent of fisheries worldwide are in jeopardy of collapse due to over-fishing. Clearly, something needs to be done. Yet, what has long been considered the obvious answer - restrictions on fishing - has been shown time and time again to be the wrong answer. The right answer is enlightened use of markets.

The fundamental cause of the depletion of fish stocks is well known to economists: virtually all ocean fisheries are “open-access,” that is, fishermen - small operations or large corporations - can fish all they want. ... Each fisherman receives the full benefit of aggressive fishing (that is, a larger catch), but none pay the full cost (an imperiled fishery for everyone). One fisherman’s choices have an effect on other fishermen (of this generation and the next), but in an open-access fishery ... these impacts are not taken into account. What is individually rational adds up to collective foolishness, as the shared resource is over-exploited. This is the “tragedy of the commons.” What to do?

Government intervention is, alas, required. Fishermen don’t welcome such regulation in their economic sphere any more than anyone else does. And they have a point. Conventional regulatory approaches have driven up costs, but not solved the problem. And we know why. If the government limits the season, fishermen put out more boats. If the government limits net size, fishermen use more labor or buy more costly sonar. Economists call this over-capitalization. Costs go up for fishermen (as resources are squandered), but pressure on fish stocks is not relieved.

The answer is to adopt in fisheries management the same type of innovative policy that has been used for decades in the realm of pollution control - tradeable permits, called “Individual Transferable Quotas” ( ITQs) in the fisheries realm. Sixteen countries - some with economies much more dependent than ours on fishing - have adopted such systems with great success. New Zealand regulates virtually its entire commercial fishery this way. It’s had the system in place since 1986, and it’s been a great success, putting a brake on over-fishing and restoring stocks to sustainable levels ­- while increasing fishermen’s profitability!

There are several ITQ systems already in operation in the United States, including for Alaska’s pacific halibut and Virginia’s striped-bass fisheries. More important, the time is ripe for broader adoption of this innovative approach, because a short-sighted ban imposed by the U.S. Congress on the establishment of new ITQ systems has expired.

The first step in establishing an ITQ system is to establish the “total allowable catch.” The next step - and a crucial one - is to allocate shares of that total limit to fishermen in individual quotas that are theirs and theirs alone (read: well-defined property rights). Setting the individual quotas will not be easy. The guiding principle should be simple pragmatism - using the allocations to build political support for the system. Making the quotas transferable eliminates the problem of overcapitalization and increases efficiency, because the least efficient fishing operations find it more profitable to sell their quotas than to exploit them through continued fishing. If you can’t catch your whole share, you can sell part of your quota to someone else, instead of buying a bigger boat.

In addition, these systems improve safety by reducing incentives for fishermen to go out (or stay out) when weather conditions are dangerous. ... Further, because ITQ systems eliminate the motivation for government to limit the duration of the fishing season, supplies available to consumers improve in quality. Prior to the establishment of an ITQ system for Alaskan halibut, for example, the government had reduced the fishing season to just two days, but subsequent to the introduction of the system, the season length grew to more than 200 days.

A decade ago, environmental advocates - led by the Environmental Defense Fund - played a central role in the adoption of the sulfur dioxide allowance trading program that’s cut acid rain by half and saved electricity generators and rate-payers nearly $1 billion annually, compared with conventional approaches. The time has come for environmentalists to join forces with progressive voices in the fishing industry and in government to set up ITQ systems that can keep fishermen in business while moving fisheries onto sustainable paths.

The allocation of individual shares is, as noted above, crucial, and the danger in having the government set the individual quotas is that "pragmatism" and the desire to "build political support" will lead to political favoritism in the allocations, that large firms will have an advantage in capturing the quota regulators, etc. For these reasons, and others, it seems like an auction mechanism would work better, at least for the initial allocation, but perhaps there are political objections to auctions that preclude this option (though the fact that such strong political forces exist would argue for a market based allocation mechanism even though those same forces would prevent such a mechanism from being implemented).
