How Off-farm Employment Affects Technical Effi ciency of China’s Farms: The Case of Jiangsu
Using three-wave survey data for four villages of Jiangsu Province in China, the present paper examines whether and to what extent off-farm employment affects the technical efficiency of agricultural production. The level of technical efficiency is measured using a stochastic frontier production function approach. Based on estimation results from instrumental variable panel quantile regressions...
متن کاملQuantile Regression for Dynamic Panel Data
This paper studies estimation and inference in a quantile regression dynamic panel model with fixed effects. Panel data fixed effects estimators are typically biased in the presence of lagged dependent variables as regressors. To reduce the dynamic bias in the quantile regression panel data model I develop an instrumental variables approach that employs lagged regressors as instruments. I show ...
متن کاملThe Influence of Accounting Information Use on Small Farm Inefficiency
This paper aims to estimate a translog stochastic frontier production function in the analysis of a balanced panel of 147 mixed Catalan farms in a five-year period (1989-1993), in order to attempt to measure and explain variation in output inefficiency scores with a one-stage approach. The mean output efficiency in the period analysed was estimated to be 62.3%. Using techniques for confidence i...
متن کاملProduction Frontiers with Cross-sectional and Time-series Variation in Efficiency Levels*
In this paper we consider the efficient instrumental variables estimation of a panel data model with heterogeneity in slopes as well as intercepts. Using a panel of U.S. airlines, we apply our methodology to a frontier production function with cross-sectional and temporal variation in levels of technical efficiency. Our approach allows us to estimate time-varying efficiency levels for individua...
متن کاملLabor Productivity Growth in the Kansas Farm Sector: A Tripartite Decomposition Using a Non-Parametric Approach
We use nonparametric production function methods to decompose farm-level labor productivity growth into components attributable to efficiency change, technical change, and factor intensity. The estimation is accomplished using balanced panel data drawn from the Kansas Farm Management Association for the period 1993 to 2007. We find that labor productivity growth is primarily driven by factor in...
