10 Long Beach and Eldon Dvorak
Some remarks need be made about my job at Cal StateCollege at Long Beach during 1965–1967. In 1965, it was very easy to find ateaching job in economics. I received unsolicited offers from England,Australia and Alaska. I went to Long Beach because it was a one-hour drive toUCLA. I needed to consult Jack and Armen about my dissertation. My greatfortune at Long Beach was to share an office with Eldon Dvorak, the man wholater played an important role in the development of the Western EconomicAssociation. After only several months Eldon was telling colleagues that CalState Long Beach will someday be remembered of having employed Steven Cheung.Of course it was a hyperbole, but it did me no harm, and in 1966 Eldon and LongBeach students help me to earn the best teacher award in economics among the 18state colleges. This was good for my immediate academic future, becauseprospective employers would naturally query whether a Chinese could speakEnglish well enough to teach properly.
Teaching 12 hours a week at Long Beach was a heavyload, but Eldon, a senior member of the department, would arrange for me thebest possible schedule. In the early spring of 1966, I read a Chinese articlesaying that after land reform in Taiwan, introduced in 1949 to reduce andrestrict the landlord’s rental share to substantially below the market level,agricultural output increased sharply. This did not make sense to me, so I wentto the library to see what I could find to support or refute this claim by theTaiwanese government.
It just so happened that the library possessed acomplete set of the Taiwan Agricultural Year Book, containing extremelydetailed reports of annual yields of different crops in different localities.At first, I thought that for political propaganda, the Taiwan government hadinflated the figures to demonstrate the success of land reform. But afterseveral weeks I could detect no lies: Agricultural yields did jump aftercontrol of the landlord’s share percentage was imposed. It would be verydifficult to cheat when the data were so meticulous and detailed, and I couldfind no inconsistency after weeks of careful checking.
One evening in March 1966, I sat down and firstworked out the equilibrium of sharecropping without the sharing restriction,then injected the sharing restriction, and to my great surprise found thatagricultural yields would rise. It took me only one evening to come up withthis theory. After two more days spent going over the analysis repeatedly andfinding no flaw, I asked Eldon to sit down to listen carefully to what I havedone. I proceeded very slowly, step by step, and after each step I waited untilEldon fully understood and agreed. Eldon asked many questions along the way,and I would say, “Slow down, Eldon, slow down.” I would not continue until hefully understood my reasoning at every turn. After three hours Eldon said,“Steve, this theory of yours is going to be earthshaking.”
It is a simple theory, obvious almost, but verydifficult to accept. When I presented my findings to a UCLA seminar in May1966, everybody disagreed. When the first of my sharecropping analysis (Cheung 1968) appeared as a lead article in JPEin October 1968, the journal received a number of comments saying I was wrong.Bob Mundell, then JPE editor, asked whether I would like to reply, but Isaid no.
I will always remember Eldon fondly. In the spring of1967, he solicited a small grant of $500 to finance my one-man photographicexhibition at the Long Beach Museum of Art. He himself even made wooden framesfor the pictures in his own garage when the money ran out. It was to become themost successful art exhibition in the history of that museum, with headlinecoverage in the newspapers, viewers drawn from afar, and they twice extendedthe length of the exhibition period.
11 My association with Coase
In 1962, I made a copy of Coase’s 1960 paper onsocial cost and carried it in my pocket for months, read it over and over againuntil the sheets fell into small pieces. What happened was that I could notunderstand the meaning of externality. Though it was a popular topic at thattime for some reason I had never discussed externality with Armen, and evenstranger is that in 1967 I discovered that Coase himself had never heard ofthat term. No teacher at UCLA could answer my query on the meaning ofexternality, although they all claimed they knew what it was. My efforts tounderstand externality eventually led to the publication of a paper on thestructure of contracts in 1970, followed by a paper on bees in 1973 (Cheung1973), and a pamphlet on social cost in 1978 (Cheung 1978).
My deep understanding of Ronald’s 1960 paper igniteda friendship which has become legendary, and which in all likelihood will berecorded in the economic history of China. It began in the fall of 1967, when Iwalked into Ronald’s office at the Chicago Law School and introduced myself:“Professor Coase, my name is Steven Cheung, a student of Alchian, I had spentseveral years reading your paper on social cost.” He was sitting and reading,raising his head, and asked: “What did I say in that paper?” I replied, “Yourpaper is about the constraints subject to which contracts are made.” He stoodup, and said, “At long last somebody understands me. Let us go to lunch.”
12 A happy share of the take and aCoase error
It was the intellectual highlight of my life, to beable to walk up and down the Chicago campus with Coase and discuss economicsduring my tenure there in 1967–1969. Talking about the future of economics, Iexplained my view that Coase’s 1960 paper would change economics. Nearly half acentury has past, and if one does not mind the tedious task of going throughthe Chinese Internet, one would find that I am credited as the founder ofcontract economics, Coase the founder of transaction costs, and Alchian thefounder of property rights. I am happy with my share of the take, but would notmind trading with Ronald for his. As for Armen’s property rights, I find it toodifficult to obtain testable propositions and therefore use the associatedconcepts less and less over time. But Armen’s beautiful insights on pricing andcompetition are so interesting that I use them more and more. I may be the onlystudent who inherited fully Armen’s thinking. Picking a seat close to theclassroom door has paid-off handsomely!
An great moment came when, in writing a piece on thefuture of China in 1981 (Cheung 1982), I found a flaw in Coase (1960): If transaction costs are zero,there would be no market! Both Ronald and Ken Arrow later concurred with thisview. I did not know how important this discovery is until twenty years later,when I began to include the dissipation of rent as a part of transaction costs.But I had to wait until a few years ago to come up with a beautiful theorem oftransaction costs substitution: Markets emerge as the result of one type oftransaction costs (the cost of using the market) substituting for another type(the dissipation of rent).
13 The Chicago school
In the Foreword to a collection of my Englishwritings, Coase noted that when at Chicago I studied the thinking of eightgrand masters, including himself, and absorbed and extended their ideas andmade them my own. It was the Chicago School at its peak, with a gathering of economictalent surpassing any other group in history. I venture to predict that it willnever be seen again.
But the Chicago School was on the verge of decline.Uzawa left the same year I did (1969), Mundell a year or two later, thenFriedman and Director retired, Harberger moved to UCLA and Griliches toHarvard. Harry Johnson was seldom around. Although the replacements weresuperb, the departure of Milton and Aaron and Al spelled the end of a paradigm.The critical mass of the Chicago School disintegrated at that time. Puttingbrilliant minds together is a necessary but not sufficient condition to form anacademic school of historic significance. When Al Harberger tried to persuademe to stay in Chicago, he rightly pointed out to me that the 1967–1969 groupwas unsurpassed and in all likelihood will never be seen again.
At Chicago, I was a small figure surrounded bygiants. I shared an office with a wonderful Donald McCloskey, who taught me howto write better English. I adored and imitated the writing style of Stigler.George was a truly brilliant man. He belonged to the Business School, and Iloved to drop into his office to get knocked about by him. Once he dropped intomy office, with Don also sitting there to listen, and said, “Steve, I haveeverything essential for a great economist, but no original ideas!” I replied,“George, I am full of original ideas, but nothing else!” He knew all along Iadored him, and to show him that I, too, could handle the history of economicthought, I wrote a long chapter on the development of sharecropping theory,detailing the thinking on the subject from Adam Smith to Gale Johnson. After heread the manuscript I went to see him and told him that is how the history ofthought should be handled. George knew I scored one-up on him and said: “Butyou are wrong in saying that Marshall understood the concept of cost. He didnot!” And he went to the bookshelf to find a copy of Marshall’s Principles,and turned to the page in which there was one sentence demonstrating thatMarshall did not understand cost. Yes, Stigler was not only brilliant, he wasone of the finest scholars I had the honor of knowing.
