This paper by Trygve Haavelmo was never submitted to a journal. The paper has been transcribed from Haavelmo's handwritten notes for a seminar given in 1942. The notes were kept by Haavelmo and were not known to exist by anyone else until Haavelmo died in 1999 and left his scientific remains to the Department of Economics, University of Oslo. The paper was retrieved from these personal archives by Olav Bjerkholt, who transcribed it from the original handwritten manuscript and submitted it to Econometric Theory.
