What determines the efficiency cost of taxation in the presence of optimization errors? Employing recent results quantifying efficiency cost when consumers are subject to biases, this paper shows how budget adjustment rules, debiasing, and the nature of tax perception affect efficiency cost....

How quickly does marginal utility diminish? It depends on the dimension along which we consider concavity of the utility function. This paper estimates the distribution of heterogeneous curvature parameters in individuals' utility functions from hypothetical choice data, while carefully...
