I appreciated all of their summaries, especially Arjun's since he highlighted an often-ignored cause of the concentration of income and wealth: increasing economic returns from capital versus labor. However, none of the panelists mentioned that the discipline of economics is itself to blame at least in part for the growth of economic inequality, by exporting disproved neoclassical models of the economy into the public realm. Accordingly, I asked the panelists to what extent the cultural environment of economics (with a unique set of disciplinary values, beliefs, and norms based in utilitarianism) has contributed to the rise of economic inequality in the United States and elsewhere. In general they responded in the affirmative, although with a number of qualifications.
P.S. An overview of the talk can be found here.
