Estimating the total factor productivity change in northern India using non-parametric malmquist productivity index

Total factor productivity change is found to be negative for the three top foodgrain producing states of northern India. The value of TFP is found to be equal to 0.987, i.e, -1.3%. The study identified the main component leading to a fall in TFP and found a lack of technical progress. The study suggests that the focus should be on developing technologies that will help the farmers to realize higher output employing the lesser amount of inputs.
