Market production and productivity: The effects of cash cropping on technical efficiency in staple crop production

To meet increasing food demand, most developing countries cannot rely on expanding the crop area, but will need to stimulate yield growth arising from increased factor productivity. This can be achieved through more efficient utilization of inputs to produce maximum output given existing technologies. Low productivity arising from technical inefficiency negatively impacts on household income and food security by reducing...
