From decision problems to dethroned dictators

Abstract: Economic models as well as aggregation and decision problems with "holes" in the domain can be difficult to analyze because, unexpectedly, they are related to Arrow's Impossibility Theorem: embedded within the model may be "topological dictators." But, just as it is possible to remove the negative impact of Arrow's dictator by recognizing that the problem is caused by not using crucial, available information (about voter preferences), the obstacles confronting these economic decision problems can be removed by identifying what kind of available information is not being used.
