Ronald Coase Institute



Interview with Ronald Coase



Inaugural Conference
International Society for New Institutional Economics
St. Louis, Missouri, USA
September 17, 1997

Editor's note: To introduce the interview, John Nye of the Economics Department, Washington University, writes, "Ronald Coase, the first president of the Society, has been a leader in creating ISNIE. Part of the interest in forming the Society arose from his view that the mainstream members of the economics profession have failed to live up to the promise of the field inherent in Adam Smithís work: they have overemphasized the formal and abstract aspects of theory at the expense of empirical and institutional research. Prior to the inaugural conference of ISNIE, several members of the Society met with Professor Coase in St. Louis for a question-and-answer session, asking him to expound on New Institutional Economics and the aims of the Society, and moving from there to a wide-ranging discussion of the economics profession and his hopes for the future of economic research."
The interviewers were Tawni Ferrarini, Northern Michigan University (who also videotaped the session); John Nye, Washington University; and Alfredo Bullard and Hugo Eyzaguirre, INDECOPI, Lima, Peru. The interview was transcribed from video by Alexandra Benham. Editing has been very minor.

Ferrarini: What is New Institutional Economics?

Economists have never considered until recently the role that institutions play in the working of the economic system. In fact, the institutions determine the way in which the economic system operates.


Nye: What about the old institutionalists? How does the new institutionalism differ?

The old institutionalists were concerned in the main with describing institutions rather than with analyzing them, thatís basically the difference.


Nye: Could you tell us some more about how the new institutionalism will affect or change standard conventional economics?

Well, it wonít so much change conventional economics as reshape it and replace it. In my mind, the New Institutional Economics is economics. Itís what economics ought to be. Existing economics is a theoretical system which floats in the air and which bears little relation to what actually happens in the real world.


Nye: Could you expand on that? Is the problem the methodology of conventional economics or is the problem the subject matter?

I would say it has no subject matter. Thatís the problem.


Nye: Is it because you think that conventional economics is more about an analytic framework than it is a subject matter?

Itís concerned with the development of a theory, a theory which is not related to what actually goes on in the economic system. Harold Demsetz explained how this has come about. Adam Smith introduced the notion of the invisible hand or the pricing system coordinating the working of the economic system. What economists have done in the time since then is to formalize this system. It deals with a system of extreme decentralization. It is not the system that actually exists.


Nye: Could you give us an example of something that New Institutional Economics treats or studies better than conventional economics? Could you expound on that?

The New Institutional Economics is not a single body of thought. There are a whole series of separate strands which have not been brought together and indeed in my view should not at the moment be brought together because we donít know enough to do it. So I think these separate strands should develop, and from time to time people will be able to mesh them together. The part Iíve been most interested in is, of course, the relation of economics and law. Unfortunatelyóand this is one of the difficulties with the New Institutional Economicsóthat part of the relationship of economics and law which analyzes the legal system has gone ahead much more than that part of the subject which deals with the effects of the legal system on the economic system. That is to say, what people have done is to use economics to study the legal system rather than discuss how changes of the law affect the actual way the economic system operates.


Nye: Thatís a good subject to pursue. Many economists would say that since the publication of your 1960 article which contained the germ of what people call the Coase Theorem, it has been assimilated into economics, and yet you are suggesting that the combination of economics and the law has not been well done yet. Could you comment on the way economists have taken your work and developed it, versus the way you would like to see it developed?

I think the success of the Coase Theoremóbecause itís discussed all over the placeóis an interesting illustration of whatís wrong with economics; because, if you read "The Problem of Social Cost," it occupies perhaps four pages. Itís useful. I think itís useful because you can show, using it, the type of contracts that would have to be made in order to have an efficient economic system. But then you have to introduce, having done that, the obstacles to doing it. Then you see how the system actually works. But many people have only read the four pages or only thought about the four pagesóone of the reasons theyíve done that, of course, is itís the most abstract part of the article.


Nye: So you think what they like about the Coase Theorem is the abstract nature of it, but theyíre not seriously interested really in the gist of your article?

Absolutely. The article has been very successful for the wrong reasons. To people who like success thatís all right, but to people who are concerned with the development of the subject itís not a very good thing.


Nye: Letís talk about what you think research would look like if it had been successful for the right reason. What kinds of research would you observe if it were successful for the right reasons?

Youíd be concerned with the types of contracts people make in different situations, how the ability to make these contracts depends on the existence of various institutions, of various laws, of the type of educational system that exists, and so on. You would have begun to see what it is that makes possible the types of contracts youíd like to make. You get into the problem. At the moment, that is being completely ignored.


Ferrarini: You argue in "The Nature of the Firm" that the firm is the supercession of the price mechanism. Planning and the price mechanism co-exist in an economy. Depending on the cost of an organization and transactions, the agents will decide which one to use. Letís talk about the economic system as a whole. How should a society decide which economic system to choose? Is there a more efficient economic system and why?

Well, there is no one way better economic system, because everything depends on the society youíre in. You may have views on the part that educational or religious organizations play in economic life; but if you have a society in which the only educated people are the clergy, you have a very different view of what the role should be of religious organizations. That is an extreme example. There was a time in England when the chief politicians were also cardinals and other clerics, but you wouldnít from that infer on the whole that itís a good system to have cardinals in charge of economic policy. It might have been at a certain time. I canít give an answer to that particular question simply because you get a different answer for every country and every historical situation.


Nye: But that argument has been used in the past to justify almost any economic system, some of which have been marked failures. What guidance can you give to a country, particularly a developing one, looking for a means of deciding where to draw the line?

Well, there are two. First of all, they should make a study of how their actual economic system operates, what the important factors are that encourage development. And the next thing is to be cautious in drawing conclusions. Itís so easy to go wrong. There are so many wrong ways of doing things and so few right ones.


Nye: According to the typical International Monetary Fund prescription, neoclassical theory suggests steps to follow toward a market-oriented economy: privatization, deregulation, macroeconomic stability, and so on. Is that enough? How should we think about the problems of determining the conditions for a properly functioning market economy?

I donít think itís enough just to think in those terms. One should also think in terms of the institutions of that country, particularly the social institutions, and build from where you are. It seems to me a mistake not to start from the point where you are. To try and change a country dramatically, pull it up by the roots and start again, that seems to me wrong. In this respectóand I donít know whether Iím right or notómy feeling is that at the moment things are moving better in, say, China than in Russia simply because they have built on the existing institutions. They have household-responsibility contracts which they have been able to develop because it was very easy to move from a commune to a family system because of the social organization of the family in China. You could turn it into an economic unit. You could develop contracts, with the result, I understand, that output in the agricultural field has doubled as a result of these contracts. Whereas what you had in Russia, if you could get rid of a collective farm, you would have a lot of unemployed bureaucrats and farm laborers. So obviously I would think you have to go about things in a different way in these two countries. I think weíre going to learn a lot from the efforts which people are making for privatization in different countries. Weíre going to find out a lot about the ways not to do it. I donít know that I can say what the way is to do it, because we have so much to learn, but I certainly donít think thereís one way.


Nye: But a Russian might come to you and say, "We have so many institutions we need to reform and change, but political realities make it difficult for us to reform all of them at the same time. Where should we start? How can you help us think about this problem?"

I wouldnít try. I would say, you know your institutions. I donít know your institutions. One of the things that went wrong after the war was that people went around from country to country telling them how they should operate, and they gave the same prescription for each country. They knew nothing about these countries. Of course the answer they gave then was, "move to socialism."


Bullard: With recent reform experience in Eastern Europe and in developing countries, many have studied the question whether the appropriate legal framework and the improved enforcement of the rules is not enough. Do you think that beliefs play also an important role in the agentís decisions and therefore in the performance of the price system? Is there then a market culture that needs to be developed in these situations?

Yes, I think so. When you get a society in which people are completely unaccustomed to operating in a market system, you are not going to get a very good market system. Thatís perhaps another reason why Iím all in favor of caution so that people can learn how to operate a market system. I donít think you want to think simply about introducing prices, because if you give people the right institutions the prices will emerge. They do need to have institutions within which they can work. They do need to have institutions that they can understand, that they have experience of operating. Now again I think that will vary from place to place. I suspect that the difference in the performance of different countries in Eastern Europe is related to the length of time they have been under a communist system, because under a communist system you donít learn how to operate a market system. I think the difference between East Germany and West Germany is very interesting here. Itís sort of surprising that different attitudes emerge so quickly. Iím surprised that there was this difference between the attitudes of the Germans in East Germany and West Germany after only forty years.


Bullard: Is there a role for the state in the development of this market culture? And is there a role for the state in the reduction of transaction costs in the economy?

Well, there is a double role for the state. One is, not to stop things happening. Thatís very important, not to get in the way. On the other hand, Iíve never felt that you could get a property rights system without the use of state powers. You can in narrow areas; trade associations and others can form organizations to set up what is in effect a private legal system. Itís very hard to do that when youíre dealing with people with very diverse interests.


Bullard: In the developing countries, government intervention has resulted in the emergence of important underground economiesóinformal economies. For example, in Peru, in the last thirty years most urban development has been the result of agentsó private agentsóoperating outside of the legal system. They have created their own property rights. They have created their own enforcement mechanisms. The informal sector of housing generates half of the gross national product. It influences more than half the labor force. How can your theory of New Institutional Economics explain these phenomena?

I would have thought it was rather easy to explain. If the government in fact doesnít allow certain activities or impedes them in various ways, people try to establish them. But, of course, lacking the enforcement powers of the state, they have to adopt their own. They often are very inefficient, arbitrary, intermittent, and so on. Iím sure you know more about what happened in Peru. But the enforcement mechanisms arenít necessarily particularly efficient ones, and the intervention of the government is also intermittent and uncertain. So sometimes they will prevent something and sometimes they wonít. Sometimes theyíll encourage something and sometimes they wonít. So you have an economic system where people are very unsure of their rights and therefore not as willing to trade and invest as they might be.


Bullard: In many of your writings you argue that the government usually tends to do too much in an economy. How to define an adequate level of intervention of the state in the economy? What about regulation, for example, regulation for consumer protection, antitrust, or that kind of issue?

Well, you cannot say that regulations might not improve things; for example, standardization is an example. On the other hand, regulation can also make things bad. What has been puzzling to me in the studies that weíve made in the United States is how many of the regulations make things worse, although thereís no particular reason why they have to make things worse. The answer that I have given is that in the United States the government operates on such a massive scale that people donít really know whatís happening. The only people who really are interested or able to follow these things are the people who are being regulated, and their interests do not necessarily coincide with the interests of other people. At the present time here, the government operates on such a massive scale that in this room where we are there are probably hundreds of agencies which have regulations which impinge on what is happening here. No one knows about them except the people who are immediately affected by them. They are therefore interested in seeing that the regulations are of such a character as to help themselves. So you get a lot of bad regulation. The studies we published in the Journal of Law and Economics gave us very few good regulations. It doesnít seem inevitable that this should be, and I think if we got the governmentís intervention in the economic sphere much reduced, weíd get much more sensible regulation. Whether that is true or not, I donít know. At any rate, that is my view. Itís very easy to see that you can get good regulation. One that I happen to know about is the screw thread agreement: so that you have standardization on screw threads such that itís possible for people in different countries to use the same screws. It might have happened, and it sometimes happens, without government action. In other cases it only seems to come about if you do have government regulation.


Bullard: One of the temptations that the government has in developing countries is try to solve the poverty problem or the unfair distribution problem through regulations or through intervention. For example, we have a case in Peruó a very small case but I think it will show what is going onówhere a person goes to a store, not a normal store but a vendor on the streets. He buys a pair of shoes, and these shoes cost around two dollars. Theyíre very cheap. That night he goes to a party: he bought the shoes to go to a party. In Lima it never rains, but it rains that night. And the shoes become softer and softer, and they disappear. They were made from paper. And the problem that the governmental agency in charge of consumer protection has at the moment is, "Well, I have two ways to deal with this. One, I cannot accept that poor people have to buy paper shoes. On the other hand, I can decide that paper shoes are the only chance poor people have to have something on their feet. The regular shoes are too expensive." Should the government decide which kind of shoes people have to use, in that kind of situation, even when we are talking about very bad quality of the product? The problem is, is there space for the state in this kind of case or should we let the things go on as they are?

In a case like this I wouldnít see the need for the government regulation at all. On the whole, people are pretty good judges of what is appropriate for them. Naturally, if you are poor, you donít want to spend most of your money on a high-grade product because that would mean you would not be able to spend money on other things. The meaning of being poor is that you have to buy shoes made of paper and other things.


Nye: Whatís your attitude toward large-scale redistribution at the expense of property rights? Massive taxation, or land reform, or confiscation from the rich to redistribute to the poor?

It operates the same way as regulation. On the whole, whatever you do, the smart people will take advantage of it. Take the changes in the tax laws. Itís very dubious whether they changed the net distribution at all. Theyíve just made the system less efficient.


Ferrarini: Recently there was an article in The Economist that attacked economics or economistsí ability to explain accurately, with their theories, current events. How will New Institutional Economics specifically help economists make individuals like the person who wrote this article better understand that economists can provide fairly accurate explanations, as well as improve their abilities to do so?

Well, Iím not sure that the writer of the article is wrong. I have not read it, but judging from what you say, it says it seems right on the whole. Economists have not given very good explanations as to why economic arrangements are made in the way they are. But I think they could, and I think there are two ways in which this could be done. One is to make empirical studies, not to develop a theory but find out what happens. And the second way is for people to specialize in particular areas so they know what theyíre talking about.


Ferrarini: When you talk about the particular areas, are you talking about different social, political and economic frameworks where you have specialists come in and study each aspect?

I think particular industries, transactions, countries. It means youíre going to get a whole lot of studies which are at the present stage difficult to relate to one another. But thatís the state in which we are.


Ferrarini: So youíre interested basically in having individuals come together and collectively study how political, social and economic institutions act upon and interact with each other?

Not come together. Do it themselves.


Ferrarini: Do it separately, individually?

Yes.


Ferrarini: Then what about merging the final product? How are you going to bring everything together? Why would you not want to bring things together?

I want to bring them together when you can bring them together. We are not ready yet. We need to have all the individual studies done. Then some new Adam Smith or someone like that will be able to do it. One of our problems is that weíve got to understand this interrelated system. But you canít understand the interrelated system if you donít know how the individual parts operate. We donít know how the individual parts operate. That weíve got to do first of all.


Ferrarini: Economists, in my mind, pretend that they know how the individual parts operate. And this is stated in principles texts all over the place. How do you think New Institutional Economics is going to change the way we teach the principles of economics?

Well, itís going to change it in this way. We wonít just talk about the supply and demand in the determination of prices. Weíre going to talk about what is demanded and what is supplied and what is priced. It seems very odd to me. Adam Smith not only introduced the notion of prices coordinating the economic system but he also pointed out that our standard of living depends on the real flow of goods and services. But somehow we donít study the real flow of goods and servicesóIíve always said that the economists invented the widget. They introduced it because it doesnít mean anything. And we price widgets. Well, we want to discover what it is thatís priced. Minasian pointed this out when he was dealing with radio and television broadcasting where the marginal cost is zero and economists said that therefore the price should be zero. Minasian pointed out that if you just broadcast a squeak, the price would be equal to marginal cost but you wouldnít get anything from it. By just considering pricing and not what is being priced, you miss the whole point.


Nye: I take it that youíre in favor of collections of empirical studies, almost like taxonomies of different industries, of different groups, of different contracts. Is that more the sort of issue you like?

Yes. I do not know what problems people should be investigating. Let them choose their problems. Weíll gradually develop. You know, how would biology have developed if people hadnít studied what the heart did, what the kidneys do?


Nye: Part of what determines what economists study is the demand and supply of economists in academia. Recent studies have argued that many graduate students believe that knowledge of the economy is not a prerequisite for being a good economist. How does one change the way in which they are educated, to take your perspectives into account?

Well, I donít think itís going to change all at once, but in different sub-disciplines a change will take place. It depends on the composition of the people in them, the persuasiveness of people, the employment policies, the courses that are given, what articles editors of journals acceptóand this will be different in different fields.


Nye: But until now this has not given the results youíve wanted in terms of the profession as a whole. Is it your view that people are sufficiently disenchanted with the way things are or that people in the New Institutional Economics are sufficiently persuasive that they are going to be successful in making change from within, in reversing some of the trends of the last twenty years?


Itís no different from any of us. If we have some sort of illness or disease or problem, you get along with it, you accept it, and then it gets so bad that you feel you ought to do something about it. Now I think that in economics people are now beginning to think that things have got so bad that one ought to do something about it, and therefore those people who have always wanted to do something about it have a more sympathetic audience than in the past. I think that is the present situation. You get lots of statements to the effect that what economists are doing is not particularly useful.


Eyzaguirre: Probably development economics is one of the areas that I think we have advanced the least. We donít know much about how economies start to develop. For example, you said that how people contract is very important. And we havenít done much about comparing how people contract in developing countries and how they do it in developed countries. Would you agree that New Institutional Economics has a lot to contribute in this area?

When you say area, itís the individuals working who are going to make the contribution, and I would have thought that we could learn vastly more than we do. I will give an example from Latin America that always has been of interest to me. You get countries with high rates of inflation, extraordinarily high. What forms of contracts do people make in order to handle this problem? What difficulties does it cause in contractual arrangements? You would think that it would make things very difficult. But the sort of answer I get is, "Oh well, we draw up contracts in a foreign currency." That obviously is not the whole answer, and Iíve never seen a good study of exactly how people handle the inflation problem. But I have been looking and I have been asking and I havenít got the answer. Thatís an obvious problem and I would like to see people tackle it. But Iím not expecting to see the goal that I would like to see achieved within under a hundred years or something like that.


Bullard: According to the Coase Theorem, if transaction costs are zero then the efficient outcome will be achieved regardless of the legal rules. Is that always true? Complex legal rules make judgesí decisions more unpredictable, and that increases transaction costs in uncertainty, so it is not entirely true that that you can have any legal rule in this situation. For example, in torts the fault rules are more complex than the strict liability rule because the tort attempts to apply a standard that is not easy to apply and predict. How important is it to have here simple rules, understanding by simple rules here rules which are easy to apply for judges and are easy to predict by society?

I donít know where I ought to go on this question. We need to think of how the Coase Theorem is going to be used. That is to say, is one going to use a simplifying assumption and say "Iím going to ignore this factor." For example, one might say, "Iím going to study how a bullet flies through the air, and Iím going to ignore the effect of gravity." People do this sort of thing; itís very sensible. But if you say, "Iím going to ignore the effect of gravity in total," you donít have a bullet. So youíve got to handle these things in a sensible way, and what I find is in discussions of the Coase Theorem, people donít handle it in a sensible way. It is a teaching device. Itís to say, "Letís ignore this for the time being and see what happens." And if you ignore transaction costs, you see their importance, you see the arrangements that have to be made. And then you can say, "Oh, this is what you do in a world in which there are no transaction costs. Well, now letís move to one in which we have transaction costs and see how it operates." Itís a stage in oneís thinking. Thatís the way I regarded it. But people got stuck on this assumption because, as I say, by being abstract and unreal, economists feel quite at home since thatís the world they already inhabit.


Nye: You seem to be a great adherent of common sense judgement, as opposed to a formal mechanistic method of deciding what is right and what is wrong. But common sense is not so common. Is it your view therefore that part of the tradition of economics that youíd like done is the ability to transmit to subsequent generations of economists some sense of judgement of what constitutes right and wrong in abstractions?

You know, I saw a statement once of Niels Bohr, who is the originator of quantum mechanics, a very great man. He was always distrustful of formal and mathematical arguments. When people made such arguments, heíd always say, "Oh youíre just being logical; youíre not thinking." What we want to do is to move people from being logical to thinking. If you judge economists on the basis of their logic, theyíre very good, I mean theyíre probablyó some of themóeven better than the physicists, but theyíre not thinking.


Ferrarini: Would you say New Institutional Economics is changing the economics world as we know it?

Well, the world actually is very little affected by what economists do, so I donít think we can say that a change in the views of economists is affecting the economic world, although if you ever get a decent economics which is useful to people in the real world, it will. Thereís a very interesting caseóI think you probably know about itóa firm, I think in St. Louis, got rid of its economists because now that you have futures markets, you donít need them. They were engaged in activities which the market can now do perfectly well. Well, thereís more to economics than that.


Nye: You are speaking of macroeconomic forecasting in particular. Do you see any role for macroeconomics in the New Institutional Economics? It seems to be the one field that is essentially left out of the New Institutional Economics.

Thatís right. I donít know how it will be affected, but my feeling is that at the moment we know that the forecasts are commonly wrong, so we know that theyíre not doing a very good job in forecasting. That is to say that they donít understand what the relationships are between these broad aggregates. My guess is that one of the reasons is that you are dealing with these broad aggregates. Until you strip them down much more, you canít really forecast very well. I would expect that the New Institutional Economics, because it will give data about individual business activities, would be of help there, though I know nothing really about macroeconomics.


Nye: Let me ask one last question. It sounds like youíre an adherent of really traditional price theory in the tradition that goes back to Adam Smith and perhaps the old Chicago school as opposed to the new one. What youíre suggesting is that we return to our roots as joint interest in price theory and the institutions of market economies, jointly?

Yes. The point Iím going to make when I talk in the meeting is that economists boast that Darwin got his ideas from Malthus and Adam Smith. Well, to me, what is interesting is to see what has happened since Darwin in biology and what has happened to economics since Adam Smith. The differences are startling. They really understand how biological processes work in a way that we do not understand how economic processes work.
