Standardization and its problems are not unique to telecommunications. Compatibility may be important even if there is no physical network. For example, one can use nuts and bolts from different manufacturers; one can play the same records on different brands of gramophone, and so forth.

Benefits and Costs of Standardization We will describe three types of benefit from standardization: cost sav- competitive ings, effects, network and externalities. will We mention then some social costs that are less obvious than the benefits. 2.1 Benefits of Standardization 2-1.1 Cost Savings By allowing greater scale economies (enabling different manufacturers to exploit economies of scale in using a common supplier), use is a of interchangeable parts, and by allov;ing the standardization reduces production costs. staple of economic history; see for instance Landes (1969, This 1983), Hemen- way (1975)'.

Although systems ex ante, incom- patibility destroys competition ex post^. Thus, we should recognize that there may be effects of standardization on competition: 6 When the products of different makers are standardized, • directly in price and performance. Lack of standardization is uct differentiation. If variety is mostly "spurious", erse tastes but merely splits the market, i.e. a they compete form of prod- does not serve div- then this differentiation is ineffi- cient. If variety is valuable in itself, or if it represents the trying out of different approaches to it is to firms have compete problem, a on then not clear whether it and performance price of a better is standard product, or whether it is better to have them compete on product design. Standardization can commit producers to compete • for spare or replacement parts, complementary inputs, Often, the market for such items (for instance, model) is a or in an "af termarket" peripheral devices. replacement fenders for a car natural monopoly, and the original manufacturer (car maker) has an advantage in taking the market (because he makes the original fenders). Absent standardization, this the auto industry, is possible source of after-sale profits; a is notorious it that indeed, in spare parts have a much higher profit Sometimes such pricing policies are inefficient (for in- margin than cars do. because buyers will inefficiently substitute away from the complemen- stance, tary input), and if anticipated by buyers, that is it may be profitable for the seller (and nutualiy beneficial) to com.T.it to low or reasonable prices for afterparts. • Standardization will achieve As well as protecting against this''. exploitation from ex-post standardization protects against orphaning.

In a simple model (1985c) we can ask the following question. Suppose that there are two types of users, group A and group B, each of whom prefers a different standard. Consider three possible outcomes: both standards could be provided (thus catering to diverse tastes), or only group A's preferred stan- dard could be provided, or only group B's.^^ We show that there is for too little standardization, opti.Tium is for two incompatible reverse cannot standard to exist, single e in the following sense: it can happen that the but the unique equilibrium is for standards to persist (one for each tvpe of buyer), happen. Intuitively, the tendency a externality imposed by one while the group of buyers on the other is alv;ays negative if the first group chooses to be incompatible. However, there can be multiple equilibria, and it is compatibility to be an equilibrium even though the optimum is patibility and variety.

This may well be the most important anticompetitive effect from standards. Below, we discuss some other possible effects.

The announcement can be predatory in the sense that the firm that undertakes the action ficing short-run profits in order to cause the exit or failure of v;hen it a is sacri- rival, succeeds in doing so it enhances its future profits. Moreover, it and is reasonable to expect v;hen installed base is important that future re-entry may be blocked, so that the usual problem in explaining what can be predatory is not present. It is also worth noting that the standard tests for predation may fail to detect the predation. See our 1965b paper. 17 5. Incentives for R&D 5.7 Excess Inertia and R&D Incentives How does the possibility (discussed above) of excess inertia affect the research development and of (R&D) new technology? At first incentives for glance, would seem that the influence of excess inertia on incentives for it R&D will be Even if straightforv7ard. firm develops a not certain that it v;ill be adopted in the market; wards for R&D are means that part of less the than they would be without better system, a implies this excess it that the inertia. is re- This also inefficiency caused by excess inertia is invisible to even the most careful study of inventions not adopted, R&D projects never get started (or pursued) as a since presumably many result of anticipated iner- tia. that argument is based on considering only one potential inno- However, vation.

As the the "base" incentive for R&D grows over v/ill be time, inertia strongest early v.'ill m the tend to increase^ ^. Thus industry history before 18 the standard gets locked in. Also, the time when a new technology seems taking over may be the best time to introduce a further innovation, to be since the former has no installed base. 5-2 Network Externalities and Licensing of Patents In a market with important netv;ork externalities, there is an extra in- centive to licence patented or sponsored technology. It does not pay for an a inventor to keep his new technology to himself. Indeed, it may pay to licence at no charge to some buyers with large volumes but low willingness to pay. For example, computer makers have been very willing to donate machines to schools and universities. Another example: Xerox licenced its local area network "Etliernet" at no cost to other suppliers. become a presumably intended to ensure that Ethernet v;ould and that the originator the industry edge, or make standard, It \>/ill have enough of is sufficiently uncompetitive, a competitive the originator will that satisfactory profit from its share of the market for the standardized a product.

Such translation, however, is sometimes impossible and is often so difficult that standardization remains important. 2. It 3. Cost reductions may be valued by users or by makers (or both), depending on what economists call the incidence of cost savings, which is a matter of market structure. For example, in a perfectly competitive market, all cost savings that reduce marginal costs are passed on to buyers, but cost savings that reduce fixed costs but do not affect marginal costs are not. In imperfectly competitive markets, some cost savings may go to enhance the profits of sell- ers . For example, Fisher (1979) writes: To the extent that certain boots are associated with certain bindings- -the real competition tai<e5 place between binding-boot combinations- 4. 5. We mean this term in a broad sense, to include not only computers and their peripheral devices, but also cameras and lenses, ski boots and bindings, nuts and bolts, autos and fenders, etcetera. 6. See for instance Farrell, 1985. This raises the question of why sellers might resist standardization, given that it enhances the value of their product and also helps tov/ards an efficient selling system. The answer may lie, as Katz and Shapiro (1985a) suggest, as Berg in some sort of costs of standardization. Perhaps more plausibly, (1985) has suggested, standardization somehov; makes competition more direct. Thus firms trade off the incentive to maximize the value of their product against the desire to restrain competition. We are also v;orking on this line of inquiry. 7. If a seller is large enough, there may be a presumption that someone would take over these support services, but it is typically not the large sellers that suffer from this fear. E. In m.arkets with a high (or potentially high) degree of vertical integration, moreover, buyers may not v;ish to be strategically dependent on a supplier who may later become a direct competitor. Sometimes a user may avoid a de facto standard for this reason: the user fears that the de facto standard setter may exploit his position. Some of the standards decisions of the European community reflect such a concern. For an interesting history of European standards decisions on color television, see Crane (1979). 9. 10. Indeed, some antitrust decisions have suggested that an ovmer of a network may have an obligation under law (as opposed to regulation) to allow interconnection by competitors, if the network becomes an "essential facility". 22 which it sometimes is, a seller would 11. If it is technically feasible, always wish to have one-way compatibility: his buyers get the advantages of the whole network, while other firms' customers only get the externalities associated with their small networks. A classic case of this is the competition that led to the strange-shaped holes in the safety razor blades that dominated the market until the seventies. 12. For example, see Dixit and Stiglitz (1977), or Spence (1976). 13. For a discussion of the possibility of compromising on the Berg (1985). standard, see 14. For another analysis of standardization with differences in tastes over standards, see Berg (19S5). The work of Katz and Shapiro (1985b), and Farrell and Saloner (1985b), although not explicitly about the efficiency-variety those terms. They analyse the evolution of tradeoff, can be interpreted standards over time v;hen buyers at different times have different preferences or different opportunities. m We focus on what Arthur (1984) has called "non-sponsored" technology. That there is no ovmer of the new (or the old) standard v;ho can subsidize early adopters in order to get a new standard rolling. Interesting questions arise (Katz and Shapiro, 19o5b, Hanson, 1985) if the technology is sponsored, and also if, v.-hile the nev; standard would not be owned, its early developer v;ould have a substantial first-mover advantage if it succeeds. (We briefly treat the question of first-mover advantage belov;.) 15. is, 16. ers, This term means that each decisionmaker knows the preferences of all othand everyone knov;s that, etc. 17. Sometimes the installed base v;ill be physical capital; in other cases the human capital invested in training on the old system v;ill be more important. The t^'pev7riter keyboard case (Da\-id, 1935a) is an interesting intermingling of the two IS. A related problem (without the dynamics) is the problem of uneconomic bypass in telephone markets. It is v.-idely predicted that, if pricing is constrained by uniformity requirements, bTOass will become very popular and v;ill reduce the value of being on the netv;ork (here, for cost-sharing reasons) to such an extent that the bypass is socially inefficient. A-gain, an autarchic technology may reduce the value obtained from a netv/crk technology; again, this would not happen if pricing were not constrained. not speculate here on V7hether any particular standard switch is Brock (1975) describes the announcement of IBM's System 360 in terms that suggest such an interpretation. Honeyv;ell had announced a computer knovm as the K-200, together with a translator device (called the Liberator) making it compatible v;ith the IBM 1401. This combination competed directly and favorably v;ith IBM's 1401 machine, v;hich was then the market leader. IBM's System 360, v/hich was announced shortly after Honeyv;ell's announcement, was incompatible with the 1401 and the K-200, and yet (whether because the 360 was superior, or because of IBM's reputation as a de facto stanIS. We v;ill predatory. Hov;ever, 23 dard setter) customers chose to commercial viability of the H-200. wait for the 360, thus destroying the m California Computer Products Corp. v IBM Corp., 613F.

IBM's rivals have also complained about insufficient advance notice of Evidently, firms that IBM's changes in its (and de facto industry) standards. depend on following the lead of a de facto standard setter are at a competitive disadvantage if they learn about standard shifts only late in the day. IBM has agreed to announce standard shifts in advance, as a result of an EEC antitrust action. 21. 22. Details available on request. 23. This may account for some "waves of innovation": no sooner does innovation A start to succeed than innovation B pushes it out of the way; in contrast to many years. It may other industries in which there has been no innovation also account for the tremendous economic growth sometimes observed after warOnce a large fraction of tlie existing time destruction of the capital stoclc. stock is destroyed, there is (or can be) a general expectation that new tecliniques can profitably be put in place. See Shleifer (1985) for a business-cycle model related to this observation. m 24 References Arthur, B., "On Competing Technologies and Historical Small Events: The Dynamics of Choice under Increasing Returns," mimeo, Stanford, 1983 Berg, S., "A Duopoly Model of Technological Externalities and Compatibility Standards," mimeo.
