¹ In a June 1, 1965 speech Wm. McChesney Martin, Chairman of the Board of Governors of the Federal Reserve System, spoke of “disquieting similarities between our present prosperity and the fabulous twenties.” Offsetting these similarities, however, in his only reference to the stock market, the increase in stock market credit was said to be smaller now than at that time. (New York Times, June 2, pp. 1, 69.) Despite overall fears, the Chairman evidently felt no concern about the stock market.

⁶ While the criterion variables may not be independent of each other, the effect of the use of first differences is to virtually eliminate the intercorrelation of the independent variables.

⁸ One would have to assume that banks respond to the higher absolute return on business loans (as well as to possible related advantages of business lending) when business demand increases, rather than to higher relative returns, since over the period considered the call loan rate (based on average December figures) has risen slightly as compared with the business loan rate. (Data on call loan rates secured from the Federal Reserve Bank of Cleveland.)

¹⁰ Although margin requirements in the various regressions play the role of both dependent and independent variable, the equations escape inconsistency because of the varying lags in the relationships. Changes in margin requirements (as dependent variables) have their closest relationship with security credit with a two quarter lag and with security prices when the latter are lagged one quarter. Changes in security credit and prices (as dependent variables) are most closely linked with changes in margin requirements of the same quarter (now the independent variable). In this way the various relationships involving margin requirements are consistent with each other.

¹⁴ In the equations shown, stock market purchases, nonfinancial expenditures and current receipts after deductions (the flow of funds equivalent of disposable personal income) are expressed in their actual flow form. We have also tested the effects of expressing them in first difference so that all the variables are uniformly expressed in first differences. The effect is to strengthen the conclusions reached below. That is, the effect of bank security credit on financial flows becomes weaker (significance levels decline although the negative relation remains) at the same time that the relation with nonfinancial expenditures becomes more significant (and remains positive).

We also note some effects from these adjustments on the significance of the “outside” explanatory variables—income and financial dissaving. The latter variable loses its significance in all of the equations with this being true of the disposable income variable in the financial flow equations.

¹⁵ It should be pointed out that in earlier work using flow of funds data 1939–56, we did find a significant impact of bank security credit on net increases in financial assets. Other variables used in the same equation were gross increases in consumer credit, net increase in “other”: security credit, net increase in mortgage credit, and the flow of funds equivalent of disposable personal income.
