Extract 3.4 Yoram Barzel, Economic Analysis of Property Rights (2nd edn, Cambridge University Press, Cambridge, 1997), pp. 101–2

In 1958, the Convention on the Continental Shelf was signed in Geneva . . . The provisions of the convention divided among the countries bordering the North Sea some of the commonly held attributes of that sea, particularly those related to minerals. Two factors had been working to enhance the value of the North Sea in the years preceding the agreement. First, underwater drilling, which was becoming more widespread, was declining in cost; second, various signs were emerging that the region contained natural gas and crude oil reserves. The countries surrounding the North Sea could conceivably have unilaterally extended their territorial rights towards the middle of the sea. Oil companies, however, were not going to invest resources in searching for oil unless they expected their potential legal ownership and, concurrently, their economic ownership of that oil to be secure. The preceding discussion suggests that the increase in value of the oil resources of the North Sea generated forces to better delineate rights over it.
By reaching an agreement, the countries involved gained ownership of segments of the sea. They could then either exploit their sea rights directly or grant them to private parties and let those private concerns exploit them. Subsequent events proved that the formal agreement and the accurate delineation of borders was ultimately of great value. When the North Sea countries convened to establish rights over the sea, no one knew where oil would be found, so it was easy to arrive at a formula that would give each country the territory nearest to it without generating much dispute regarding the precise setting of borders. The formula actually selected was that any point on the sea (and on the sea bottom) belonged to the country to which the point was closest.
As it turned out, many of the major oil and gas discoveries lay close to the border between the Norwegian and the United Kingdom sectors. Since the border was precisely marked, ownership of these finds was not in dispute. There is little doubt that without the agreement oil companies would not have searched in that area. The value of the clear delineation is further illustrated by the following observation. There is a deep trench in the Norwegian sector of the North Sea. Laying a pipeline across the trench is prohibitively costly. Some of the Norwegian oil deposits are on the United Kingdom side of the trench, which seems to make the United Kingdom a more natural owner of that area than Norway. Consistent with the Coase theorem, however, once rights were delineated, there was little difficulty in developing the area. Indeed, some of the Norwegian oil is shipped by pipeline to the United Kingdom.
Notes and Questions 3.1
1What does Hardin mean by ‘the commons’? Some of the examples he gives (e.g. fish in oceans, air and water into which pollutants are released) are what we describe here as no-property, i.e. an unowned resource which everyone has a

76 Property Law
privilege to use but no right not to be excluded from. At least one other (National Parks) is open access communal property, i.e. a resource which everyone has a privilege to use and a right not to be excluded from, and another (grazing land leased by cattlemen on the western ranges) is limited access communal property, where each cattleman-tenant has a privilege to graze cattle, a right not to be excluded from doing so, and a right to exclude non-cattlemen- tenants. Up to a point, Hardin’s failure to distinguish these different categories does not matter: his argument (that each individual has a positive and a negative incentive to over-use the resource) applies equally to all three categories. However, the solution to the problem of over-use may vary from category to category. In relation to each of the examples given by Hardin, and in the light of what is said in the other materials extracted here, consider whether use regulation might best be achieved:
(a)by making the resource subject to private ownership;
(b)by self-regulation by the users acting in concert;
(c)by state ownership; or
(d)by state regulation by imposition of quotas, or by taxation (most famously advocated by Pigou, The Economics of Welfare (consider how this would work)), or by other means.
2There are many documented cases of (b) above, i.e. cases where users of scarce no-property, or of scarce limited access communal property, have avoided depletion of the resource by self-regulation of their use. See, for example, the elaborate rituals and use patterns associated with use of scarce resources in Australia by aboriginal tribes, documented in Milirrpum v. Nabalco Pty Ltd (1971) 17 FLR 141 and Mabo v. Queensland (No. 2) (1992) 175 CLR 1 (both extracted at www.cambridge.org/propertylaw/ and discussed in Chapters 4 and 5), which have been highly successful in conserving resources for thousands of years (but not necessarily exploiting them to their full potential). Major studies of similarly long-standing self-regulated communal systems have been produced in response to Hardin’s analysis: see, for example, Chakravaty-Kaul,
Common Lands and Customary Law, Dahlman, The Open Field System and Beyond (an analysis of the open field system in medieval England specifically undertaken to demonstrate what Dahlman argued was a highly efficient system of communal land usage, whose eventual disintegration was caused not by Hardin’s ‘tragedy of the commons’ but by other complex social and political factors) and Stevenson, Common Property Economics (a study of Swiss alpine grazing commons we refer to again in question 9 below). References to further examples can be found in Ellickson, ‘Property in Land’; Fennell, ‘Common Interest Tragedies’; and De Alessi, ‘Gains from Private Property’.
3Would the factors that Hardin identifies as leading inexorably to over-exploi- tation of the pasture be removed if the animals were also communally owned? In other words, has Hardin identified a problem arising only when there is a

Justifications for property rights 77
mixture of private and communal ownership, which would not arise if all relevant resources were communally owned? At one level, this appears to be the case: if each animal is communally owned, each herdsman shares equally the benefits and detriments of grazing an additional animal. However, this does not alter the argument; it merely converts the problem from one of over-exploita- tion to one of under-exploitation. If the value of the pasture and the animals grazed there is to be maintained, never mind maximised, it will be necessary for the herdsmen to expend labour on them. But, while each herdsman bears 100 per cent of the burden of the labour he expends, he has to share the benefits accruing from his labour with all the other herdsmen: most of the benefits are external to him. Consequently, so the argument goes, he has no incentive to work harder because he has no means of ensuring that every other herdsman will do the same. In other words, in the case of any type of communal use of resources by human beings, an interface between communal ownership and private ownership is inevitable, for so long as we each own our own labour.
4Does Demsetz sufficiently distinguish between limited access communal property and no-property? If not, does this affect the force of his arguments?
5Demsetz assumes that those labouring for the communal good will inevitably work less hard than those labouring exclusively for their own benefit. Examine the arguments he puts forward. Do they, as Grunebaum suggests, oversimplify the issue?
6Demsetz argues that the interests of future generations must be taken into account if resources are to be put to their optimal use, and that this will only occur if the resource is privately owned. To what extent does Grunebaum disagree with this? Who do you think is right?
7According to Demsetz, how are externalities internalised by private property? Is he right?
8Elsewhere in the article, Demsetz applies the same analysis to corporate ownership: see Chapter 8.
9In his study of Swiss alpine grazing, Common Property Economics (referred to above), Glenn Stevenson found a wide variety of patterns of ownership of alpine grazing meadows within a relatively small area of Switzerland, and this appeared to be typical of other parts of Switzerland and also of alpine areas in other countries. Many of the meadows are communally owned (and have been for up to a thousand years); others are privately owned by individuals and either used by the owners personally or let out to other users; others are co-owned by a small number of private co-owners. Communal ownership exists in several different forms. In all cases (private and communal), use is highly regulated, sometimes by state regulation but more usually by elaborate

78 Property Law
self-regulation, which also takes a wide variety of forms. Stevenson was unable to establish whether the communally run meadows were more or less efficient than the ones that were privately run. He was able to establish (by analysing milk yields) that they were less productive, but it was not possible to tell whether or not this was attributable to other differences: it could have been the case that they would have been even less productive under private ownership. In other words, a possible explanation (perhaps confirmed by the longevity of the mixed pattern of ownership) was that the pattern of ownership which had evolved for each meadow was the one to which it was most suited. As Stevenson concludes (pp. 234–5):
Whether or not an eventual net revenues analysis [i.e. looking at the productivity relative to the costs input] indicates that commons management is generally poorer than private management, common property will still have its place in specific instances. In Switzerland, natural conditions exist under which only commons will work, regardless of the general incentives inherent in commons management. Particularly the remote areas are unsuitable for private management. Because of the costs of managing the resource privately at these locations, rents under common property may well be higher. Thus, even if generally poorer performance of common property is found in a net revenues analysis, not all commons will be inferior, nor can the conclusion be reached that all commons should be converted to private property. This notion parallels the more general idea that particular resource configurations exist – from fisheries to the atmosphere – for which we are compelled to find common property rather than private property solutions.
10Barzel refers to the Coase theorem, which is that, in the absence of transaction costs inhibiting the proper working of the market, the efficient allocation of resources will occur wherever the entitlement is first put. We look at this again in Chapter 6.
3.2.2. Viability of single property systems
Even if economic efficiency is the overriding criterion for measuring the success of a particular form of property ownership (and we consider below whether there are other alternative or additional criteria), and even if we are persuaded that in principle private ownership is the most efficient form of ownership, we might nevertheless want to question whether it would be economically efficient to have private ownership of all resources.
As a matter of historical record, in most societies private, communal and state ownership coexist. It is difficult to envisage a society which did not recognise some form of private ownership of some resources, however exiguous. This is probably true even of a wholly Marxist society. As Jeremy Waldron points out (Waldron, The Right to Private Property, pp. 425–6) it is an integral part

Justifications for property rights 79
of Karl Marx’s argument that private property should be abolished in total. He quotes Marx as responding to bourgeois critics of the socialist programme in the following terms:
You are horrified at our intending to do away with private property. But in your existing society, private property is already done away with for nine-tenths of the population; its existence for the few is solely due to its nonexistence in the hands of these nine-tenths. You reproach us, therefore, with intending to do away with a form of property the necessary condition for whose existence is the nonexistence of any property for the immense majority of society. In one word, you reproach us for intending to do away with your property. Precisely so; that is just what we intend. (Marx and Engels, Communist Manifesto, p. 98)
Waldron comments:
Throughout his work, Marx is adamant that the indictment against capitalism is not merely the fact that private property happens to be distributed unequally or in a way that leaves millions without any guaranteed access to the means of production; the problem is that private ownership is a form of property that has this characteristic necessarily. No matter how noble your egalitarian intentions, the existence of any distribution of private property rights in the means of production will lead quickly to their concentration in the hands of a few. Thus egalitarian intentions, so far as private property is concerned, are hopelessly utopian, for they underestimate the dynamic tendencies of the system they are interested in. ‘For us the issue cannot be the alteration of private property but its annihilation.’
Nevertheless, even Marx had to have some way of recognising something akin to private property in relation to such ownables as one’s labour and personal possessions. He refers to such things as ‘private possessions’, and although he pays little attention to precisely what rights individuals would have in such things they appear to go beyond purely possessory rights, even if not extending to full rights of alienation for reward, bequest and commercial exploitation (see further Grunebaum, Private Ownership, pp. 135–40, for a discussion of what these rights might be, consistently with what he terms Marx’s free development principle).
At the opposite end of the scale, a society in which all resources are privately owned is probably also not feasible. This is not simply because there are some resources that any society would wish to make available for public use, such as roads and national defence systems. Resources which are to be made available for public use can still be made the subject of a modified type of private ownership which ensures public access, as we know from the privatisation of public utilities that occurred in many Western states in the late twentieth century. Nevertheless, economists recognise a category of resources, usually referred to as public goods, which many argue are most efficiently held by public ownership. As Demsetz has argued elsewhere (Demsetz, ‘Ownership and the Externalities Problem’, pp. 297–9), in the case of some resources such as the two examples already given,
