Outcome bias occurs when an evaluator considers ex-post outcomes when judging whether a choice was correct, ex-ante. We … formalize this cognitive bias in a simple model of distorted Bayesian updating. We then examine strategy changes made by …

In this paper, I present a simple characterization of the sample selection bias problem that is also applicable to the … problem of sample selection bias is fit within the conventional specification error framework of Griliches and Theil. A simple … estimator is discussed that enables analysts to utilize ordinary regression methods to estimate models free of selection bias …
