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...

A recent note by Merrilees [15] concludes that Divisia index numbers as employed in our studies of productivity change [ l l , 141 represent a new perspective on the analysis of productivity. Merrilees concludes further that Divisia index numbers are appropriate for the explanation of productivity change, but that they should not be used for measurement. In this note we examine and reject both ...

the performance of a decision making unit (dmu) can be evaluated in either across-sectional or a time-series manner, and data envelopment analysis (dea) is a useful method for both types of evaluation. the malmquist productivity index (mpi) evaluates the change in efficiency of a dmu between two time periods. it is defined as the product of the catch-up and frontier-shift terms. in this paper, ...

Impact assessment of climate change on potato productivity in Punjab for three potato cultivars of late (Kufri Badshah), medium (Kufri Jyoti) and early (Kufri Pukhraj) maturity groups was carried out for A1FI scenario of temperature and atmospheric CO2 of the years 2020 and 2055. The simulation study was done using WOFOST crop growth model for potential production at 13 locations in Punjab. The...
