Pigou vs Coase, as refereed by Demsetz

This is a good summary of the Pigou vs. Coase debate on externalities. I have one comment: That the author should have brought Hayek into the picture. After all, the piece was published in 1996. What follows is a kind of executive summary.

Demsetz sees the debate on externality as one between two ideals: An ideal state (with perfect information) and an ideal market (also with perfect information and zero transaction cost). Taken to the limit, both models do not generally produce identical solutions. It is well known that the initial distribution of wealth and income affects market outcomes. Change that distribution and the economy rests somewhere else. With Pigovian state intervention, one also needs to factor in the initial distribution of wealth and income as a determinant of political process. Still, it is reasonable to imagine that both models arrive at the same end-point if they started with the same initial conditions.

Demsetz then concludes, based only on theoretical considerations, that the choice between the two models is one determined by preferences for freedom and the final (and/or initial) distribution of incomes and wealth.

Once we depart from the ideal to actual governments and markets, the choice between the two solutions would then have to take into account how much information there is (available) in the competing models, and how well they would reduce transaction cost. Here, Hayek would pronounce in favor of Coase, if only because Hayek believes that the market is more capable of ‘discovering’ such phenomena as efficient technologies and consumer preferences. Transaction cost can be seen as another form of externality, so we start to run the risk of arriving at a proverbial slippery slope.

Nonetheless, Demsetz is essentially right. Transaction cost is not at the kernel of Coase; and neither did Pigou ignore transaction cost. What was being debated was who should have the property rights to the externality, a question that economists usually avoid but one that Coase faced head on.

Philippines vs China


It seems that we can boil down the legal conclusion of the arbitral ruling as based on only two key questions.

One, what is an island? A rock is not an island. So there. Even if China builds up a rock, it still cannot become an island. It may be a feeler island, but still that’s not an island in the legal contemplation of international law. UNCLOS says that artificial islands are not properly islands. (Otherwise, any oil rig can claim to be an island!)

And there’s the economics of islands. Under UNCLOS (Art. 121(3)), only natural formations that can sustain economic life on its own, can have maritime zones, such as an Exclusive Economic Zone (EEZ).

Two, what is an archipelagic state? It is one composed of many islands. PH is archipelagic. China is not. It appears that China conceded its status as a coastal (non-archipelagic) state when it signed the UNCLOS because the UNCLOS classifies countries in only two ways — archipelagic or coastal. The Tribunal ruling, in para. 573, categorically restates that China is a coastal state.

The answers to these two questions determine the EEZ, which is 200 miles from the coastline of a non-archipelagic state; and 200 miles from the archipelagic baseline of an archipelagic state. The baseline is a point-to-point boundary that encompasses or includes the islands of an archipelagic state.

An outlying island in the South China Sea, even if it could be claimed as territory of China, cannot result in an expanded EEZ based on archipelagic baselines because China is not an archipelagic state. (Consider the following related question: Can the US consider the waters between Hawaii and Los Angeles as “internal waters” using the archipelagic baseline approach? The answer is in the negative because, like China, the US is not an archipelago.)

The EEZ of an outlying island is 200 miles around that island because such an island is treated like any other land territory (Art. 121(2)). The EEZ cannot extend beyond the 200 miles (beyond this, there would be continental shelf (something else) or open international waters (high seas)). And an EEZ could be delimited if competing EEZ’s from other nearby states exist.

The ruling states that the disputed territories are not at all islands, and therefore cannot provide China an EEZ. Practically all the major disputed territories are inside the EEZ of the Philippines because it is an archipelagic state. Therefore, even ‘rocks’ can be useful to the Philippines, if they are located within the EEZ based on the archipelagic baselines of the Philippines. These useful rocks include Scarborough Shoal, Second Thomas Shoal, Johnson Reef, McKennan Reef, Hughes Reef, and Mischief Reef. Some of the disputed rocks are outsize the EEZ of the Philippines.

An important caveat is that territory and sovereignty are matters of international law not subject to the UNCLOS. Nonetheless, disputes relating to the EEZ are pointedly the subject of the UNCLOS.


EEZ means maritime zones (not necessarily territory in the usual ‘conquest’ or ‘historic’ sense) that we can, under international law and UNCLOS, consider as usable only by us. We can, by negotiation, lease or allow others to use the EEZ, but the extent to which the Philippine Executive can do this is governed by the 1987 Constitution.

NB: The map of PH EEZ is from Wikipedia.

How are money and inflation institutions?

The macro textbooks usually say that inflation comes from the supply of money. In a regime of fiat monies, central banks “compete” at providing stable money. However, some central banks’ hands are tied by their governments’ desire to use the inflation tax. If you don’t trust the local money, you can always switch to foreign exchange, gold, or even Bitcoin.

But if money is what folks accept as such, its devaluation must also come from folks collectively thinking that the central bank intends to print more.  Its rise in purchasing power can also come from holders thinking of it as a “safe” money.

Veblen once defined institutions as collective habits of thought (at p.107).  That means that to predict inflation, one must anticipate the price expectations and strategies of buyers and sellers of money. Today, cash is king, so that it makes sense to see low or even negative inflation and interest rates.

This means that the macro textbooks don’t have the full story. Inflation is also a story of institutions in the sense of Veblen.

How economists approach history

If only to inspire economics students to study history, and how to apply economics to solve historical puzzles, here’s an example of a very interesting study.

In this work, Douglas Allen and Peter Leeson explain the economics of warfare in the medieval ages, focusing on the technologies of the long bow versus the short bow.

Perhaps, perhaps, one can conclude that major human endeavors, including war and struggles for power, are drivers of innovation.  This echoes the idea of ‘creative destruction’ from Josef Schumpeter.

A matter of gravity – incomplete or inaccurate SALNs

The law firm of Dimatulac and Calaboso asked an ‘of counsel’ partner to think about the impeachment proceedings. The partner, disinclined from absenting himself from his usual golf course circuit, assigned a junior partner to do the legal legwork.

The junior partner submitted a memorandum that never saw light of day in the law firm. However, a janitor named Juanito Umbanal discovered a USB drive which contained said memorandum. Juanito gave it to a journalist, who, using the usual shield law, agreed not to identify the source of the piece.

The memorandum read as follows.

Why the Philippines is poor – the empathy solution

Here’s another answer to the question.  It says we’re poor because we are “bad”:  we have no discipline, we tolerate bad leaders, etc. etc.  Therefore, to get rich we should change ourselves.

Unfortunately, it’s not quite the right answer.  We can be good, in that sense that will make Santa Claus bring us Christmas, but still we will remain poor.

Why is that?
