Institutional Diversity and Trade

A popular argument against free trade is that the logic of trade requires identical (or at least similar) rules/institutions between the trading parties.  Dani Rodrick recently made this argument, and you can see Don Boudreaux’s response here.  There is absolutely nothing in the logic or argument for free trade that necessitates similar institutions between the partners.  Only one thing is required: both parties benefit.

However, for both parties to benefit from trade, they must inherently be different from each other.  If the two were identical, then no trade would ever occur.  Diversity in tastes, in endowments, in incomes, even in rules, are desirable and, to differing degrees, necessary.  The idea that trading partners must be similar to one another, including in their belief structures, undermines the logic of trade.

Moving from the individual level to the national level, institutional diversity helps show actual costs and benefits of various institutions.  For example, if the whole world were as protectionist as Red China in the 1950’s, no one would know what a horrible scheme that is as the whole world would have looked like massive starvation.  Fortunately, the Chinese realized their mistake and have become rapidly more open-trade, thus leading to their huge economic gains lately, but it was the fact that institutional diversity existed that such folly was understood.  If a given national government decides not to allow peaceful trading between their citizens and another group of citizens, then their citizens are harmed and the true costs of their institutions, as well as their true benefits, are not known.

Diversity is a necessary ingredient of trade.

In Stark Contrast

In booming economic times, the detrimental effects of policies like minimum wage, immigration restrictions, protectionism scarcityism, or socialism, can be hard to see.  The good growth outweighs the bad from the policies, obscuring their effects.  However, once times get tough, then the negative aspects of these policies stand in stark contrast.  By way of metaphor, imagine going downhill in a car.  Lightly applying the brakes won’t do much (depending on how steep the hill is, you may actually gain speed!).  However, if you are going uphill, even a light tap will have a large effect on the car.

Unfortunately, the obscurity generated by the good times can cause less careful thinkers to determine that there are no negative effects of the policies they want.  We see this quite often with protectionism.

We are now seeing the negative effects of protectionism and immigration restrictions here in the US following three major hurricanes that have hit in the past month: Harvey in Houston, Irma in Florida, and Maria in Puerto Rico.  In normal times, the detrimental effects of artificially high prices and artificially scarce resources tend not to be noticed.  Like the farmer who grows 100 acres of corn, and 1 acre is destroyed by parasites, it’s not too noticeable.  But if a disaster hits, and how only 10 acres can grow with 1 acre being destroyed, it’s very problematic.  When times are tough, and resources scarce, the market needs to work.  These artificial restrictions only make the scarcity worse.

Looking at disasters like Irma, Harvey, Maria, etc give us an excellent chance to test the claims of the scarcityists, that protectionism, minimum wage, and immigration restrictions grow the economy, not shrink it.  Given the tough time Texas, Florida, and Puerto Rico have is recovering basic supplies, it’s hard to believe the claims of the scarcityists.  Abundance is wealth, not scarcity.

Why Have Property Rights?

The purpose of this essay is to flesh out some aspects and properties of property rights.  For many readers, this is probably redundant.  Nothing I will write here is original or particularly new.  However, following recent conversations I have had, I feel it is worth it to rehash some of these ideas.

Property rights, defined as the right to use resources*, exist to help resolve conflicts.  In a world of scarce resources with more than one person in it, conflicts will inevitably rise.  The prototypical Robinson Crusoe, who finds himself alone on a desert island, need not worry about conflicting uses of resources.  He can choose to eat the berries or plant them, and there will be no other objections to their use.

However, once Friday comes ashore, now there is the risk of conflict.  If Robinson wants to eat berries and Friday wants to plant them, then there is a conflict; doing one necessarily means the other cannot happen.  The clear delineation of property rights, who owns the berries, in this case, helps solve/prevent the conflict.  If Robinson and Friday agree that Robinson owns the berry bushes and Friday owns the fruit trees, then Friday can use the fruit trees and Robinson can use the berry bushes to their hearts’ content.  Indeed, they could even trade with one another!

But, what about if there are conflicts with the use of the resources?  Does Robinson have any right to object to Friday’s use?  In other words, are property rights absolute?  Let me be absolutely clear by what I mean by “absolute,” and here a very little mathematical formalism would be helpful: By “absolute,” I mean that the use of the resource will be determined by the resource owner with a probability of 1.  If Joe owns a resource, and its use is determined by Joe and Joe alone 100% of the time, then his ownership is absolute.  If the probability is less than 1 at any time, then the property right is not absolute.

Going back to Robinson and Friday, let’s say that one of Friday’s trees is a coconut tree.  I have already said above that Friday has the property right to the trees.  He can use the trees for his purposes.  But does Friday and only Friday determine how those resources are to be used?  Can we think of an example where his right might be restricted, that is its use would not be determined by Friday?  Yes: Friday may not use his coconuts to bash in Robinson’s skull.  One can think of many other examples.  Therefore, Friday’s property right is not absolute.

Another example: I own a crowbar.  I can use that crowbar for many things, but I cannot use that crowbar to pry open my neighbor’s door without his consent.  Therefore, the use of my crowbar is not 100% determined by me.  For a very select few set of cases, the use is determined by my neighbor.  The property right is not absolute.

The discussion of using property to harm another (whether intentionally or not) is of major importance in law and economics.  As Ronald Coase pointed out when property rights are ill-defined, that is to what extent their use is defined, then conflicts arise.  If rights are absolute, then conflicts are inevitable and cannot have a just resolution.

To be clear, just because property rights are not absolute does not mean they are arbitrary.  They cannot be revoked, renegotiated, or reneged without due cause.  But the glorious thing about common law is that it allows for the flexibility needed to address conflicts which are at the present unseen but may arise down the road without sacrificing the right itself.

This blog post is a little over 600 words.  I will not pretend to have done justice to the issue of property rights here.  For a more detailed discussion, I’d recommend the following readings:

Institutions Matter

While cruising around Facebook this morning, I came across this argument against immigration by one Jasen Tenney:

Illegal immigration is down over 50% with Trump and now to get legal immigration way down. Glad to see them go. Since these people are so good for an economy they can make their own crappy home country a better place to live.

Jasen’s argument is somewhat typical of many man-in-the-street arguments against illegal immigration (and immigration in general).  If immigration is good for the US, if specifically, these people are really a net benefit to the country) and not, as President Trump said infamously, criminals, rapists, and drug dealers, why don’t they stay in their own country and make it a better place?

The economist’s response to this question is simple: institutions matter.  Institutions like rule of law, secure property rights, impartial judiciary, individual rights, etc (in other words, classically liberal institutions) go a long way in producing economic growth.

A person is more likely to flourish, and help others flourish, in an area with institutions that encourage economic growth than s/he is in an area that discourages or predates upon economic growth.  Why produce in an area where property rights are insecure (eg, roving bandits can just steal your stuff, or government can appropriate anything at will)?  Even the best producer may not produce anything under such circumstances.  But, under a different institutional structure, s/he may thrive.

To return to Jasen’s question that motivated this post: why can’t these immigrants simply return to their “crappy” home country and make it a better place?  Quite possibly, because the institutional arrangements necessary to make the country a better place do not exist (or are sufficiently weaker compared to the country the immigrant was headed to)!

Coase, Transaction Costs, and Environmental Entreprenureship

Today’s Quote of the Day comes from pages 7-8 of Ronald Coase’s 1988 book The Firm, the Market, and the Law [emphasis added]:

Markets are institutions that exist to facilitate exchange, that is, they exist in order to reduce the cost of carrying out exchange transactions.  In an economic theory that assumes transaction costs are nonexistant, markets have no function to perform and it seems perfectly reasonable to develop the theory of exchange by an elaborate analysis of individuals exchanging nuts for apples on the edge of a forest or some similar fanciful example.

Many readers of Coase (including economists!) misunderstand him.  This is evident in the improperly named Coase Theorem (it’s improper in that it’s not a theorem).  In fact, Coase is so often misunderstood, he felt compelled to write the book this quote is from to clarify his point!  Coase is often understood to say that, absent transaction costs (or sufficiently low transaction costs), externality issues (eg pollution, noise, etc) can be solved by an allocation of property rights and, regardless of their initial allocation, will result in a Pareto-efficient outcome.  This is correct, but only a partial understanding of Coase.

Much of Coase’s work (and work that spun off from him, such as with Armin Alchian, Harold Demsetz, Gordon Tullock, and many others including my own) focus on the role of the market in addressing externality issues.  Detractors from Coase argue that his insights, that markets for externalities can exist only if there are no/low transaction costs, are not applicable to the “real world,” since transaction costs abound and, therefore, government intervention is necessary.  But this argument represents a misreading of Coase.  In a purely ideal world, there would be no transaction costs, but then no market would be necessary.  As Coase says in the above quote, it is in the world of transaction costs that the market is most useful!  The existence of transaction costs gives rise to firms and other means of human collaboration, which in turn reduce transaction costs, and increase the market exchange of individuals (see The Nature of the Firm (1937) for a more in-depth conversation on this point).

Expanding the idea of markets, firms, and transaction costs to environmental issues, we see the rise of “enviropreneurs” (to use the phrasing of PERC), that is people who seek out and find ways to mitigate these transaction costs in order to achieve desired environmental ends; in short, a market process of environmental concerns (for a detailed look at many different kinds of enviropreneurs, see Free Market Environmentalism for the Next Generation, especially Chapter 9).  The fact transaction costs exist is not a detriment to free market environmentalism, like the detractors of Coase argue, but rather what allows it to come about!

Like Coase (and Buchanan and many others) before me, I realize the market is not a panacea.  There may be conditions for government to get involved (namely where involvement by the firm or an individual are too costly).  But the work of Coase (and Alchian and Demsetz and Buchanan and Tullock and Anderson and many others) show us that the mere existence of an externality and transaction costs is not enough to justify intervention.

Economics as a Positive Science

Following a natural disaster, one can count on two things in the opinion pages and blogosphere: economists of all stripes decrying price-gouging legislation in a disaster and proponents calling economists immoral for questioning such legislation.

The conversation/disagreement between these two is a microcosm of a much larger discussion: the difference between the normative (subjective) and the positive (objective).

Economics is a positive science.  It deals with what is, not what ought to be.  When economists argue that price ceilings (like price-gouging legislation) cause shortages, that is a positive claim: it is a claim of what is.  This claim can be empirically tested, but it does not reflect the moral positions or suppositions of the economist.  In fact, the claim carries with it no moral implications whatsoever.  The claim price-gouging legislation causes shortages carries with it no more or less moral weight than the claim the sky is blue.

Conversely, morality is a normative science.  It deals with what ought to be, not what is.  When moralists argue that raising prices during a disaster is immoral, that is a normative claim: it is a claim of what ought (not) to be.  This claim cannot be empirically tested (although it can be tested to see if it falls into various moral criteria).  It reflects the belief structure of the person making the claim.  The claim raising prices during a disaster is bad carries with it no more or less empirical weight than the claim the sky is blue is good.

Allow me to elaborate, lest I give the mistaken impression that normative and positive sciences are opposed.  Normative and positive are not opposed; in fact, they compliment each other quite well.  Normative can prevent positive from becoming abusive (think, for example, our modern sensibilities against eugenic human breeding [normative] despite knowing certain traits are genetic [positive]).  But positive can also keep normative from being “pie in the sky,” by explaining how the world is.  For example, normative claims like “one should not kill his neighbor,” are all well and good, but the positive claim that “murder happens,” is important to know, too.  Knowing the two together brings us to the conclusion that police are needed for the few who do break the law.

To apply this reasoning to disasters, knowing price-gouging legislation makes the logistical system worse is important to know, as it can help inform better forms of aid and legislation.

In short, answering a positive claim with a normative claim will get us nowhere, but the two must be given, and understood, concurrently.

Price Gouging Legislation Means Fewer Resources for Search & Rescue

Police, like any resource, is scarce: there simply is not enough to satisfy every want and need.

Because of this simple fact, anti-price-gouging legislation has two perverse effects on a disaster.  The first, and the one economists tend to focus on, is what I discussed the other day, namely that price controls create shortages.  The other, as the title of this post would suggest, is even more of an immediate threat to life and limb.

If police resources are diverted toward price-gouging enforcement, then that means there are fewer police resources for search and rescue operations!  A cop who has to spend his time making sure merchants don’t charge too much is not spending his time looking for people, or preventing looting, or distributing goods.

Just your daily reminder: scarcity is a thing
