This study examines the impact of incentives on commuters’ travel behavior based upon a questionnaire survey conducted on the Beijing Subway System. Overall, we find that giving incentives to commuters, especially fast food restaurant-related services and reduced ticket fares, has a positive...

This paper proposes a simple and efficient estimation procedure for the model with non-ignorable missing data studied by Morikawa and Kim (2016). Their semiparametrically efficient estimator requires explicit non- parametric estimation and so suffers from the curse of dimensionality and requires...

This paper presents a weighted optimization framework that unifies the binary, multi-valued, continuous, as well as mixture of discrete and continuous treatment, under unconfounded treatment assignment. With a general loss function, the framework includes the average, quantile and asymmetric...
