David Glasner — G. L. S. Shackle and the Indeterminacy of Economics


Analysis of rational expectations more than Shackle.
So in the end , I find myself unable to make sense of rational expectations except as a test for the internal consistency of an economic model, and, perhaps also, as a tool for policy analysis. Just as one does not want to work with a model that is internally inconsistent, one does not want to formulate a policy based on the assumption that people will fail to understand the effects of the policy being proposed. But as a tool for understanding how economies actually work and what can go wrong, the rational-expectations assumption abstracts from precisely the key problem, the inconsistencies between the expectations held by different agents, which are an inevitable, though certainly not the only, cause of the surprise and regret that are so characteristic of real life.
