Takashi Negishi (根岸隆 Negishi Takashi?, born 2 April 1933) is a Japanese neo-Walrasian economist.
Negishi graduated Faculty of Economics, University of Tokyo in 1956 and received a Ph.D. in Economics from University of Tokyo in 1963.
Negishi's research has provided a wide range of extensions to orthodox general equilibrium modelling. These additions have typically involved imperfect competition, stability and unemployment.
Negishi is most famous for Negishi welfare weights or Negishi social welfare function, a system of weighting welfare assessment used in the and other macro-economic analyses. These are controversial insofar as they recognize and embed into economic analysis a varying and unequal price of life across different countries. Elizabeth A. Stanton specifically criticized this approach in Negishi Welfare Weights: The Mathematics of Global Inequality, 2011, arguing in an interview that:
This is argued by Stanton and others to be both inequitable and inaccurate, as over time that "current distribution" would change, making the policy advice even more wrong than it was when it was decided.
The response of Joshua K. Abbott and Eli P. Fenchel [1] acknowledged that
often criticized on ethical grounds. [But] We show the Negishi SWF is ethically consistent with the Golden Rule, whereby the social planner weights others’ utilities at a point in time as he would weight his own future discounted utility. This result clarifies the implicit ethical assumptions embodied in many economic models. We also show that a specific link exists between Negishi weights and a generalization of the Ramsey discounting rule. "
