Abstract

The article shows that there is a profound contrast between the concepts of economics that Walras and Pareto support. This contrast is based on the way each author views human nature and, from this the pricing mechanisms and forms of rationality they assign to the agents. We show that Walras’ approach to human nature structures the connection he proposes between pure, applied and social economics while Pareto’s leads him to methodologically separate his pure economics from his sociology. According to Walras the starting point of the study of economics is not market exchange between rational individuals as many authors propose, but a specific conception of human nature that promotes a synthesis between pure and social economies. However, we show that Pareto separates pure economics and sociology by means of specific representations of real man and homo œconomicus. These differences imply that Walras and Pareto’s works no longer be related in the same way to the Lausanne School.
