The Overlapping Generations Model in 1947
指出莫里斯·阿莱在1947年出版的书中已使用世代交叠模型，比萨缪尔森1958年的文章更早，并反思作者自己为何长期未注意到这一相似性。
During the last decade, while overlapping generations provided the framework for the study of many theoretical issues, no one seems to have noticed the use of this model in the book published by Maurice Allais in 1947, Economie et intert. The introduction of the model is commonly attributed to a well-known article published in 1958 by Paul Samuelson. This note intends to bring the unnoticed anteriority of Allais' use of the model to the attention of a wide readership. The case may be of interest not only to economic theory but also to the more general historicological study of the process by which science is being built. Indeed, my role in the story is surprising and may reveal something worth remembering. I had closely studied Economie et inWret in 1948, in particular the appendix in which the overlapping generations model is used. I later worked on capital theory and intensively reflected in 1958 on the relationship between Samuelson's findings and my own results. But I did not pay attention to the similarity between the models used independently by Allais and Samuelson. It is only recently, when looking for what might be the subject of my contribution to a festschrift in honor of Allais that I became conscious of this similarity (Malinvaud 1986). In the meantime, like others, I referred to Samuelson's article when introducing overlapping generations in my own writings. '
