Three kinds of the Lotka-Volterra model transfer from biology to economics

Philosophers of science regard the Lotka-Volterra model as an exemplar of model transfer across disciplines. This article traces three cases of the Lotka-Volterra model transfer to economics during the 1960-70s. Each model represents a different kind of methodological attitude towards model transfer. After detailing the historical case studies where the Lotka-Volterra model was transferred to economics and how the economists actually adopted it into their model constructions, the following philosophical discussions on interpretation and justification suggest that formal template or structure alone does not produce successful transdomain model transfer; rather it is subject to the model builders' intentions and interpretation. In addition to interdisciplinary transfer, intradisciplinarity is also crucial to how models are constructed in order to be resituated in their economic context.
