This paper assesses the dynamics of treatment effects arising from variation in the durationof training. We use German administrative data that have the extraordinary feature that theamount of treatment varies continuously from 10 days to 395 days (i.e. 13 months). Thisfeature allows us to...

This paper identifies health determinants in urban China applying Grossman model. Using wave of China Health and Nutrition Survey in 2000, we find that education has important positive effect on health, and cost of health care services has significantly negative impact. However, effects of wage...

This paper investigates the evolution of earnings inequality in urban China from 1989 to 2006. After decomposing the variance of log of earnings into transitory and permanent two parts, we find that both components are important contributors to the total variance of earnings. We also find that...

Propensity score matching estimators have two advantages. One is that they overcome the curse of dimensionality of covariate matching, and the other is that they are nonparametric. However, the propensity score is usually unknown and needs to be estimated. If we estimate it nonparametrically, we...

Using 2002 cross-sectional data and 1998, 2000, 2002 three waves of panel data from the Chinese Longitudinal Healthy Longevity Survey, we study health in oldest old population. We measure health using the Katz Index of Activities of Daily Living (ADL) and in term of mortality. Our results...

"We use the data from the National Supported Work Demonstration to study performance of non-propensity-score-matching estimators, and to compare them with propensity score matching. We find that all matching estimators we studied here are sensitive to the choice of data set. Propensity score...
