In this paper a model of housing demand behavior is proposed, in which both monetary and non-monetary adjustment costs (termed 'attachment') are allowed to affect demand levels. An empirical implication of the model is that the individual variance around the housing demand curve is likely to...

By comparing experimental and propensity-score impact estimates of dropout prevention programs, we examine whether propensity-score methods produce unbiased estimates of program impacts. We find no consistent evidence that such methods replicate experimental impacts in our setting. This finding...
