This interview with Wassily Leontief is the first to appear in Macroeconomic Dynamics. Other interviews of importance to the history of economic thought will appear occasionally in this journal. Since this journal prizes the openness that characterizes the scientific method, the views expressed by economists interviewed in this section may span a broad range and will not necessarily represent the views of the journal's editorial board or the primary focus of the journal. However, in all cases in which Macroeconomic Dynamics publishes an interview, the journal thereby evidences its deep respect for the scholar whose interview we publish.
