Summary/Abstract

This paper employs a fully nonparametric stochastic frontier model with time and individual effects to study technical efficiency in China's post-reform economy. The panel data cover China's thirty provinces for the period of 1985-2008. The empirical results show that the average output elasticity of labor is larger than the other two inputs of capital and human capital. Based on the specified inefficiency Tobit model, the factor analysis on technical efficiency shows that the time effects of technical efficiency in China's post-reform economy are significantly contingent on the factors. There exists significant regional differences in technical efficiency in China's economic development, and a number of policy implications can be drawn.

Summary/Abstract

Teacher's holding an administrative position (AP) while teaching is common in schools in China. Does it harm the students' academic performance? This paper uses a representative survey of middle school students in China to answer the question. Using a causal identification based on schools with random class assignments, we find that the effect of a headteacher's holding an AP is negative and significant. In contrast, the effect of a subject teacher's holding an AP may be positive. The results are robust to various robustness checks. The heterogeneity analysis shows that the negative effect is driven by 9th grade students and is larger for boys, rural students, those whose parents migrate out to work, and those whose mothers have lower levels of education. Mechanism analysis suggests that head teachers with an AP devote lower levels of teaching effort, measured by time spent on grading and frequency of adopting supplementary teaching tools.
