Downward calibration property of estimated response propensities
Acta et Commentationes Universitatis Tartuensis de Mathematica, 2017 We consider four methods for estimating response propensities: three traditional ones (linear, logistic, probit) and one more recent, a decision tree method. We show that some but not all the methods produce estimates that calibrate sample totals of auxiliary variables down to the response set totals.

COMMUTING TIME AND HOUSEHOLD RESPONSIBILITIES: EVIDENCE USING PROPENSITY SCORE MATCHING [PDF]
Journal of Regional Science, 2015 ABSTRACTWe examine the relationship between individual commuting behavior and household responsibilities, with a focus on gender differences in that relationship. Using the Dutch Time Use Survey for the years 2000 and 2005, we analyze the relationship between commuting time, home production, and childcare.
