Leontief enjoyed New York. At Leontief’s request before he left Kiel, Schumpeter<br />

had sent him suggestions for people to meet in New York. In addition to Mitchell and<br />

Kuznets at NBER, Schumpeter had suggested John Maurice Clark and Ralph Souter at<br />

Columbia. 172 He enclosed with the letter to Leontief a greeting card for Henry Moore<br />

whom Schumpeter described as suffering and withdrawn. Moore had retired in 1929 and<br />

Leontief didn’t get to see him.<br />

At Columbia Leontief instead met Harold Hotelling who was an outlier at Columbia at<br />

that time as the only non-institutionalist. Hotelling had indeed been hired to take over<br />

Henry Moore’s courses in mathematical statistics and mathematical economics. 173<br />

Schumpeter had furthermore mentioned Carl Snyder at the Federal Reserve Bank of New<br />

York and also the blind Mr. Thomas, whom Schumpeter held to be one of the most gifted<br />

economists of the day. Leontief visited the Fed and met Thomas and several other young<br />

economists.<br />

In the beginning of December 1931 Leontief explained to Schumpeter what his<br />

ongoing work was:<br />

“The basic idea of my current work is the following. The ‘empirical’ explanation of<br />

economic changes must start with the isolation of primary changes from secondary<br />

ones, which can be regarded as the response of the total system. It can theoretically<br />

(mathematically) be shown that when an essential change, a ‘new combination’ i.e.<br />

an elasticity shift, occurs in any point of the economic circulation, then this will call<br />

forth in all other and particularly in the ‘neighboring’ parts of the system quite<br />

specific shifts (both in size and direction) of the supply and demand curves.<br />

If the elasticities of the individual markets are known, then the level shifts<br />

can be measured. And if the latter are determined for the ‘strategically’ important<br />

points of the circular flow, then deductions can be drawn from their configuration<br />

about probable location of the primary change at stake. The results I have achieved<br />

so far show that the task is not hopeless.” (Leontief to Schumpeter, 15 Dec. 1931,<br />

transl. by ob).<br />

This is an informative passage in view of Leontief’s earlier work and our knowledge<br />

of where he was heading, although disappointingly brief. The keyword in the description<br />

was “economic changes.” Leontief was clearly struggling with a theoretical framework of<br />

general equilibrium character, comprising several industrial markets, not necessarily<br />

172 J.M. Clark was a leading institutionalist but carried with him also parts of the neoclassical legacy<br />

of his father, J.B. Clark. Both had been invited charter members of the Econometric Society. R.<br />

Souter was from New Zealand and at Columbia 1930-35.<br />
